四、前端界面设计与实现

4.1 用户输入表单设计

创建直观且功能完整的用户输入界面，包含所有必要的参数控制：

<div class=\"card\"> <div class=\"card-header bg-primary text-white\"> <h5 class=\"mb-0\">图像生成参数</h5> </div> <div class=\"card-body\"> <form id=\"imageForm\"> <div class=\"mb-3\"> <label for=\"promptInput\" class=\"form-label\">正向提示词 *</label> <textarea class=\"form-control\" id=\"promptInput\" rows=\"3\"  placeholder=\"请输入详细的图像描述，使用英文效果更佳...\" required></textarea> <div class=\"form-text\">详细描述您想要的图像内容，越详细生成效果越好</div> </div> <div class=\"mb-3\"> <label for=\"negativePrompt\" class=\"form-label\">负向提示词</label> <textarea class=\"form-control\" id=\"negativePrompt\" rows=\"2\"  placeholder=\"不希望图像中出现的内容...\"></textarea> <div class=\"form-text\">排除不需要的元素，如: lowres, bad anatomy, text, watermark</div> </div> <div class=\"row\"> <div class=\"col-md-6 mb-3\">  <label for=\"modelSelect\" class=\"form-label\">模型选择</label>  <select class=\"form-select\" id=\"modelSelect\"> <option value=\"black-forest-labs/FLUX.1-Krea-dev\" selected>FLUX.1 (推荐)</option> <option value=\"MAILAND/majicflus_v1\">MajicFLUS v1</option> <option value=\"qwen-qwen1.5-72b-image\">Qwen-Image 72B</option>  </select> </div> <div class=\"col-md-6 mb-3\">  <label for=\"sizeSelect\" class=\"form-label\">图像尺寸</label>  <select class=\"form-select\" id=\"sizeSelect\"> <option value=\"512x512\">512x512</option> <option value=\"768x768\">768x768</option> <option value=\"1024x1024\" selected>1024x1024</option>  </select> </div> </div> <div class=\"row\"> <div class=\"col-md-4 mb-3\">  <label for=\"stepsInput\" class=\"form-label\">采样步数</label>  <input type=\"number\" class=\"form-control\" id=\"stepsInput\" value=\"30\" min=\"1\" max=\"100\">  <div class=\"form-text\">值越高质量越好但速度越慢</div> </div> <div class=\"col-md-4 mb-3\">  <label for=\"guidanceInput\" class=\"form-label\">引导系数</label>  <input type=\"number\" class=\"form-control\" id=\"guidanceInput\" value=\"7.5\" min=\"1.5\" max=\"20\" step=\"0.1\">  <div class=\"form-text\">控制提示词对生成的影响程度</div> </div> <div class=\"col-md-4 mb-3\">  <label for=\"seedInput\" class=\"form-label\">随机种子</label>  <input type=\"number\" class=\"form-control\" id=\"seedInput\" min=\"0\">  <div class=\"form-text\">留空则随机生成，固定种子可重现结果</div> </div> </div> <button type=\"submit\" class=\"btn btn-primary w-100\" id=\"generateBtn\"> <span class=\"spinner-border spinner-border-sm d-none\" id=\"loadingSpinner\"></span> 生成图像 </button> </form> </div></div>

4.2 图像展示与历史记录

设计图像展示区域，包含结果预览和历史记录功能：

<div class=\"card\"> <div class=\"card-header bg-success text-white d-flex justify-content-between align-items-center\"> <h5 class=\"mb-0\">生成结果</h5> <button class=\"btn btn-sm btn-outline-light\" id=\"clearHistory\">清除历史</button> </div> <div class=\"card-body\"> <div class=\"text-center py-5\" id=\"placeholder\"> <img src=\"assets/icons/image-placeholder.svg\" alt=\"Image placeholder\" class=\"opacity-25\" height=\"120\"> <p class=\"text-muted mt-3\">图像将在此处显示</p> </div> <div class=\"d-none\" id=\"resultContainer\"> <div class=\"text-center mb-3\"> <img id=\"generatedImage\" class=\"img-fluid rounded\" alt=\"Generated image\"> </div> <div class=\"d-grid gap-2 d-md-flex justify-content-md-center\"> <a href=\"#\" class=\"btn btn-outline-primary\" id=\"downloadBtn\" download=\"generated-image.jpg\">  <i class=\"bi bi-download\"></i> 下载图像 </a> <button class=\"btn btn-outline-success\" id=\"regenerateBtn\">  <i class=\"bi bi-arrow-repeat\"></i> 重新生成 </button> </div> </div> <div class=\"mt-4\" id=\"historySection\"> <h6>生成历史</h6> <div class=\"list-group\" id=\"historyList\">  </div> </div> </div></div>

4.3 响应式CSS样式设计

创建自定义CSS样式，优化移动端和桌面端的显示效果：

:root { --primary-color: #4e73df; --secondary-color: #6f42c1; --success-color: #1cc88a; --dark-color: #5a5c69;}body { background-color: #f8f9fc; font-family: \'Nunito\', -apple-system, BlinkMacSystemFont, \'Segoe UI\', Roboto, sans-serif;}.card { border: none; border-radius: 0.35rem; box-shadow: 0 0.15rem 1.75rem 0 rgba(58, 59, 69, 0.15);}.card-header { border-radius: 0.35rem 0.35rem 0 0 !important;}#generatedImage { max-height: 70vh; object-fit: contain;}.history-item { transition: all 0.2s;}.history-item:hover { transform: translateY(-2px); box-shadow: 0 0.5rem 1rem rgba(0, 0, 0, 0.15);}.btn { border-radius: 0.35rem;}/* 移动端适配 */@media (max-width: 768px) { .container { padding-left: 15px; padding-right: 15px; } .card-body { padding: 1rem; } .row { margin-left: -8px; margin-right: -8px; } [class*=\"col-\"] { padding-left: 8px; padding-right: 8px; }}/* 暗色模式支持 */@media (prefers-color-scheme: dark) { body { background-color: #1a1a1a; color: #e6e6e6; } .card { background-color: #2d2d2d; color: #e6e6e6; } .form-control, .form-select { background-color: #3d3d3d; border-color: #4d4d4d; color: #e6e6e6; }}

五、JavaScript应用逻辑实现

5.1 核心API调用模块

实现与ModelScope API交互的核心功能，处理异步任务和错误处理：

// 配置常量const MODEL_SCOPE_BASE_URL = \'https://api-inference.modelscope.cn/\';const API_KEY = \'your_modelscope_api_key_here\'; // 实际应用中应从安全来源获取// 通用请求头const commonHeaders = { \"Authorization\": `Bearer ${API_KEY}`, \"Content-Type\": \"application/json\",};// API调用函数class ModelScopeAPI { /** * 提交图像生成任务 * @param {Object} params - 生成参数 * @returns {Promise} 任务ID */ static async submitImageGenerationTask(params) { try { const response = await axios.post( `${MODEL_SCOPE_BASE_URL}v1/images/generations`, {  model: params.model,  prompt: params.prompt,  negative_prompt: params.negativePrompt || undefined,  size: params.size,  seed: params.seed || undefined,  steps: params.steps,  guidance: params.guidance }, {  headers: { ...commonHeaders, \"X-ModelScope-Async-Mode\": \"true\"  } } ); if (response.data && response.data.task_id) { return response.data.task_id; } else { throw new Error(\'Invalid response format: missing task_id\'); } } catch (error) { console.error(\'Error submitting generation task:\', error); throw new Error(`Failed to submit task: ${error.response?.data?.message || error.message}`); } } /** * 检查任务状态 * @param {string} taskId - 任务ID * @returns {Promise} 任务状态和结果 */ static async checkTaskStatus(taskId) { try { const response = await axios.get( `${MODEL_SCOPE_BASE_URL}v1/tasks/${taskId}`, {  headers: { ...commonHeaders, \"X-ModelScope-Task-Type\": \"image_generation\"  } } ); return response.data; } catch (error) { console.error(\'Error checking task status:\', error); throw new Error(`Failed to check task status: ${error.response?.data?.message || error.message}`); } } /** * 轮询任务结果 * @param {string} taskId - 任务ID * @param {number} interval - 轮询间隔(毫秒) * @param {number} timeout - 超时时间(毫秒) * @returns {Promise} 生成的图像URL */ static async pollTaskResult(taskId, interval = 5000, timeout = 120000) { const startTime = Date.now(); return new Promise((resolve, reject) => { const poll = async () => { // 检查超时 if (Date.now() - startTime > timeout) {  reject(new Error(\'Task polling timeout\'));  return; } try {  const taskStatus = await this.checkTaskStatus(taskId);  switch (taskStatus.task_status) { case \'SUCCEED\': if (taskStatus.output_images && taskStatus.output_images.length > 0) { resolve(taskStatus.output_images[0]); } else { reject(new Error(\'Task succeeded but no image URL returned\')); } break; case \'FAILED\': reject(new Error(`Task failed: ${taskStatus.message || \'Unknown error\'}`)); break; case \'PENDING\': case \'RUNNING\': // 继续轮询 setTimeout(poll, interval); break; default: reject(new Error(`Unknown task status: ${taskStatus.task_status}`));  } } catch (error) {  reject(error); } }; // 开始轮询 poll(); }); }}

5.2 用户界面交互逻辑

实现表单处理、状态管理和用户交互功能：

// 应用状态管理class AppState { constructor() { this.currentTaskId = null; this.generationHistory = JSON.parse(localStorage.getItem(\'imageGenerationHistory\')) || []; this.isGenerating = false; } addToHistory(entry) { // 保留最近20条记录 this.generationHistory.unshift(entry); if (this.generationHistory.length > 20) { this.generationHistory = this.generationHistory.slice(0, 20); } // 保存到本地存储 localStorage.setItem(\'imageGenerationHistory\', JSON.stringify(this.generationHistory)); // 更新UI this.renderHistory(); } clearHistory() { this.generationHistory = []; localStorage.removeItem(\'imageGenerationHistory\'); this.renderHistory(); } renderHistory() { const historyList = document.getElementById(\'historyList\'); if (!historyList) return; historyList.innerHTML = \'\'; if (this.generationHistory.length === 0) { historyList.innerHTML = `     暂无生成历史
 
 `; return; } this.generationHistory.forEach((item, index) => { const historyItem = document.createElement(\'a\'); historyItem.href = \'#\'; historyItem.className = \'list-group-item list-group-item-action history-item\'; historyItem.innerHTML = `   ${item.prompt.substring(0, 60)}${item.prompt.length > 60 ? \'...\' : \'\'}
  ${new Date(item.timestamp).toLocaleTimeString()} 
 模型: ${item.model} | 尺寸: ${item.size}
 点击查看详情 `; historyItem.addEventListener(\'click\', (e) => { e.preventDefault(); this.showHistoryItem(item); }); historyList.appendChild(historyItem); }); } showHistoryItem(item) { // 填充表单 document.getElementById(\'promptInput\').value = item.prompt; document.getElementById(\'negativePrompt\').value = item.negativePrompt || \'\'; document.getElementById(\'modelSelect\').value = item.model; document.getElementById(\'sizeSelect\').value = item.size; document.getElementById(\'stepsInput\').value = item.steps; document.getElementById(\'guidanceInput\').value = item.guidance; if (item.seed) { document.getElementById(\'seedInput\').value = item.seed; } // 显示图像 this.displayGeneratedImage(item.imageUrl, item.prompt); }}// 初始化应用const appState = new AppState();// 页面加载完成后初始化document.addEventListener(\'DOMContentLoaded\', function() { // 渲染历史记录 appState.renderHistory(); // 表单提交处理 document.getElementById(\'imageForm\').addEventListener(\'submit\', handleFormSubmit); // 清除历史按钮 document.getElementById(\'clearHistory\').addEventListener(\'click\', () => { if (confirm(\'确定要清除所有生成历史吗？此操作不可撤销。\')) { appState.clearHistory(); } }); // 重新生成按钮 document.getElementById(\'regenerateBtn\').addEventListener(\'click\', () => { document.getElementById(\'imageForm\').dispatchEvent(new Event(\'submit\')); });});/** * 处理表单提交 * @param {Event} e - 表单提交事件 */async function handleFormSubmit(e) { e.preventDefault(); if (appState.isGenerating) { alert(\'当前已有任务正在处理中，请稍候...\'); return; } // 获取表单数据 const formData = { prompt: document.getElementById(\'promptInput\').value.trim(), negativePrompt: document.getElementById(\'negativePrompt\').value.trim(), model: document.getElementById(\'modelSelect\').value, size: document.getElementById(\'sizeSelect\').value, steps: parseInt(document.getElementById(\'stepsInput\').value), guidance: parseFloat(document.getElementById(\'guidanceInput\').value), seed: document.getElementById(\'seedInput\').value ? parseInt(document.getElementById(\'seedInput\').value) : undefined }; // 验证输入 if (!formData.prompt) { alert(\'请输入提示词\'); return; } if (formData.prompt.length > 2000) { alert(\'提示词长度不能超过2000个字符\'); return; } // 更新UI状态 setGeneratingState(true); try { // 提交生成任务 const taskId = await ModelScopeAPI.submitImageGenerationTask(formData); appState.currentTaskId = taskId; // 轮询获取结果 const imageUrl = await ModelScopeAPI.pollTaskResult(taskId); // 显示生成的图像 displayGeneratedImage(imageUrl, formData.prompt); // 保存到历史记录 appState.addToHistory({ ...formData, imageUrl, timestamp: new Date().toISOString(), taskId }); } catch (error) { console.error(\'Generation error:\', error); alert(`生成失败: ${error.message}`); } finally { // 恢复UI状态 setGeneratingState(false); }}/** * 显示生成的图像 * @param {string} imageUrl - 图像URL * @param {string} prompt - 提示词 */function displayGeneratedImage(imageUrl, prompt) { const placeholder = document.getElementById(\'placeholder\'); const resultContainer = document.getElementById(\'resultContainer\'); const generatedImage = document.getElementById(\'generatedImage\'); const downloadBtn = document.getElementById(\'downloadBtn\'); // 隐藏占位符，显示结果区域 placeholder.classList.add(\'d-none\'); resultContainer.classList.remove(\'d-none\'); // 设置图像和下载链接 generatedImage.src = imageUrl; generatedImage.alt = prompt; downloadBtn.href = imageUrl; downloadBtn.download = `generated-${Date.now()}.jpg`;}/** * 设置生成状态UI * @param {boolean} isGenerating - 是否正在生成 */function setGeneratingState(isGenerating) { appState.isGenerating = isGenerating; const generateBtn = document.getElementById(\'generateBtn\'); const loadingSpinner = document.getElementById(\'loadingSpinner\'); if (isGenerating) { generateBtn.disabled = true; loadingSpinner.classList.remove(\'d-none\'); generateBtn.innerHTML = \'生成中...\'; } else { generateBtn.disabled = false; loadingSpinner.classList.add(\'d-none\'); generateBtn.innerHTML = \'生成图像\'; }}

5.3 高级功能实现

实现图像放大、批量生成和高级参数控制等扩展功能：

// 高级功能类class AdvancedFeatures { /** * 使用Real-ESRGAN放大图像 * @param {string} imageUrl - 原始图像URL * @param {number} scale - 放大倍数(2, 4) * @returns {Promise} 放大后的图像URL */ static async upscaleImage(imageUrl, scale = 2) { // 这里需要实现图像放大逻辑 // 可以使用其他ModelScope模型或第三方API console.log(`Upscaling image from ${imageUrl} with scale ${scale}`); // 模拟实现 - 实际应用中应调用相应的放大API return new Promise((resolve) => { setTimeout(() => { resolve(imageUrl); // 实际应用中应返回放大后的URL }, 2000); }); } /** * 批量生成图像 * @param {Object} baseParams - 基础参数 * @param {number} count - 生成数量 * @param {Array} seeds - 种子数组(可选) * @returns {Promise<Array>} 生成的图像URL数组 */ static async batchGenerate(baseParams, count, seeds = []) { const results = []; for (let i = 0; i < count; i++) { try { const params = {...baseParams}; // 使用指定种子或随机生成 if (seeds[i] !== undefined) {  params.seed = seeds[i]; } else {  params.seed = Math.floor(Math.random() * 1000000); } const taskId = await ModelScopeAPI.submitImageGenerationTask(params); const imageUrl = await ModelScopeAPI.pollTaskResult(taskId); results.push({  url: imageUrl,  seed: params.seed,  index: i }); // 更新进度 if (typeof this.onBatchProgress === \'function\') {  this.onBatchProgress(i + 1, count); } } catch (error) { console.error(`Batch generation failed for item ${i}:`, error); results.push({  error: error.message,  index: i }); } } return results; } /** * 生成图像变体 * @param {string} imageUrl - 原始图像URL * @param {string} prompt - 提示词 * @param {number} similarity - 与原始图像的相似度(0-1) * @returns {Promise} 变体图像URL */ static async generateVariant(imageUrl, prompt, similarity = 0.7) { // 这里需要实现图像变体生成逻辑 // 可以使用img2img功能的ModelScope模型 console.log(`Generating variant for ${imageUrl} with similarity ${similarity}`); // 模拟实现 - 实际应用中应调用相应的img2img API return new Promise((resolve) => { setTimeout(() => { resolve(imageUrl); // 实际应用中应返回变体图像的URL }, 2000); }); }}// 扩展UI功能function initAdvancedFeatures() { // 添加放大按钮 const buttonGroup = document.createElement(\'div\'); buttonGroup.className = \'btn-group mt-2\'; buttonGroup.innerHTML = `    `; document.querySelector(\'#resultContainer .d-grid\').appendChild(buttonGroup); // 添加批量生成UI const batchSection = document.createElement(\'div\'); batchSection.className = \'mt-4\'; batchSection.innerHTML = ` 批量生成
    
  
 
 
 `; document.getElementById(\'resultContainer\').appendChild(batchSection); // 事件监听 document.getElementById(\'upscale2x\').addEventListener(\'click\', () => handleUpscale(2)); document.getElementById(\'upscale4x\').addEventListener(\'click\', () => handleUpscale(4)); document.getElementById(\'generateVariant\').addEventListener(\'click\', handleGenerateVariant); document.getElementById(\'startBatch\').addEventListener(\'click\', handleBatchGenerate);}// 处理图像放大async function handleUpscale(scale) { const imageUrl = document.getElementById(\'generatedImage\').src; try { setGeneratingState(true); const upscaledUrl = await AdvancedFeatures.upscaleImage(imageUrl, scale); // 创建新标签页显示放大后的图像 window.open(upscaledUrl, \'_blank\'); } catch (error) { alert(`放大失败: ${error.message}`); } finally { setGeneratingState(false); }}// 处理批量生成async function handleBatchGenerate() { const count = parseInt(document.getElementById(\'batchCount\').value) || 4; if (count < 1 || count > 10) { alert(\'批量生成数量必须在1-10之间\'); return; } // 获取当前参数 const formData = { prompt: document.getElementById(\'promptInput\').value.trim(), negativePrompt: document.getElementById(\'negativePrompt\').value.trim(), model: document.getElementById(\'modelSelect\').value, size: document.getElementById(\'sizeSelect\').value, steps: parseInt(document.getElementById(\'stepsInput\').value), guidance: parseFloat(document.getElementById(\'guidanceInput\').value) }; try { setGeneratingState(true); const progressBar = document.getElementById(\'batchProgress\'); const batchResults = document.getElementById(\'batchResults\'); progressBar.classList.remove(\'d-none\'); batchResults.innerHTML = \'\'; // 设置进度回调 AdvancedFeatures.onBatchProgress = (current, total) => { const percent = (current / total) * 100; progressBar.querySelector(\'.progress-bar\').style.width = `${percent}%`; progressBar.querySelector(\'.progress-bar\').textContent = `${current}/${total}`; }; const results = await AdvancedFeatures.batchGenerate(formData, count); // 显示结果 results.forEach((result, index) => { if (result.url) { const col = document.createElement(\'div\'); col.className = \'col-6 col-md-3\'; col.innerHTML = `   <img src=\"${result.url}\" class=\"card-img-top\" alt=\"Batch result ${index + 1}\">  种子: ${result.seed}
 
  
 `; batchResults.appendChild(col); } }); } catch (error) { alert(`批量生成失败: ${error.message}`); } finally { setGeneratingState(false); AdvancedFeatures.onBatchProgress = null; }}// 页面加载完成后初始化高级功能document.addEventListener(\'DOMContentLoaded\', initAdvancedFeatures);

6.1 前端性能优化策略

实现前端性能优化，提升用户体验：

// 图像懒加载和缓存管理class ImageCacheManager { constructor(maxSize = 50) { this.cache = new Map(); this.maxSize = maxSize; } set(key, imageData) { if (this.cache.size >= this.maxSize) { // 移除最旧的项 const oldestKey = this.cache.keys().next().value; this.cache.delete(oldestKey); } this.cache.set(key, { data: imageData, timestamp: Date.now() }); } get(key) { const item = this.cache.get(key); if (item) { // 更新访问时间 item.timestamp = Date.now(); return item.data; } return null; } clear() { this.cache.clear(); }}// 初始化缓存const imageCache = new ImageCacheManager();// 优化图像加载function loadImageWithCache(url, prompt) { return new Promise((resolve, reject) => { // 检查缓存 const cached = imageCache.get(url); if (cached) { resolve(cached); return; } const img = new Image(); img.onload = () => { // 缓存图像 imageCache.set(url, img); resolve(img); }; img.onerror = () => { reject(new Error(`Failed to load image: ${url}`)); }; img.src = url; img.alt = prompt; });}// 替换原有的图像显示逻辑async function displayGeneratedImageOptimized(imageUrl, prompt) { const placeholder = document.getElementById(\'placeholder\'); const resultContainer = document.getElementById(\'resultContainer\'); const generatedImage = document.getElementById(\'generatedImage\'); placeholder.classList.add(\'d-none\'); resultContainer.classList.remove(\'d-none\'); // 显示加载中状态 generatedImage.src = \'assets/loading-spinner.gif\'; generatedImage.alt = \'加载中...\'; try { const img = await loadImageWithCache(imageUrl, prompt); generatedImage.src = img.src; generatedImage.alt = prompt; // 更新下载链接 const downloadBtn = document.getElementById(\'downloadBtn\'); downloadBtn.href = imageUrl; downloadBtn.download = `generated-${Date.now()}.jpg`; } catch (error) { console.error(\'Error loading image:\', error); generatedImage.src = \'assets/error-placeholder.png\'; generatedImage.alt = \'图像加载失败\'; }}

6.2 API调用优化与错误处理

增强API调用的健壮性和错误处理能力：

// 增强的API调用类class EnhancedModelScopeAPI extends ModelScopeAPI { static async submitImageGenerationTaskWithRetry(params, maxRetries = 3) { let lastError; for (let attempt = 1; attempt <= maxRetries; attempt++) { try { return await this.submitImageGenerationTask(params); } catch (error) { lastError = error; console.warn(`Attempt ${attempt} failed:`, error); // 如果不是最后一次尝试，等待一段时间后重试 if (attempt < maxRetries) {  const delay = Math.pow(2, attempt) * 1000; // 指数退避  await new Promise(resolve => setTimeout(resolve, delay)); } } } throw lastError; } static async checkTaskStatusWithTimeout(taskId, timeout = 30000) { return Promise.race([ this.checkTaskStatus(taskId), new Promise((_, reject) => { setTimeout(() => reject(new Error(\'Task status check timeout\')), timeout); }) ]); }}// 更新表单处理函数async function handleFormSubmitEnhanced(e) { e.preventDefault(); if (appState.isGenerating) { alert(\'当前已有任务正在处理中，请稍候...\'); return; } const formData = { prompt: document.getElementById(\'promptInput\').value.trim(), negativePrompt: document.getElementById(\'negativePrompt\').value.trim(), model: document.getElementById(\'modelSelect\').value, size: document.getElementById(\'sizeSelect\').value, steps: parseInt(document.getElementById(\'stepsInput\').value), guidance: parseFloat(document.getElementById(\'guidanceInput\').value), seed: document.getElementById(\'seedInput\').value ? parseInt(document.getElementById(\'seedInput\').value) : undefined }; if (!formData.prompt) { alert(\'请输入提示词\'); return; } setGeneratingState(true); try { // 使用增强的API调用（带重试机制） const taskId = await EnhancedModelScopeAPI.submitImageGenerationTaskWithRetry(formData); appState.currentTaskId = taskId; // 显示任务ID和进度 showTaskProgress(taskId); const imageUrl = await ModelScopeAPI.pollTaskResult(taskId); displayGeneratedImageOptimized(imageUrl, formData.prompt); appState.addToHistory({ ...formData, imageUrl, timestamp: new Date().toISOString(), taskId }); } catch (error) { console.error(\'Generation error:\', error); showError(`生成失败: ${error.message}`); } finally { setGeneratingState(false); hideTaskProgress(); }}// 显示任务进度function showTaskProgress(taskId) { const progressHtml = `   任务已提交: ${taskId.substring(0, 8)}...   加载中... 
 
  
 
 
 `; document.getElementById(\'resultContainer\').insertAdjacentHTML(\'beforebegin\', progressHtml);}// 隐藏任务进度function hideTaskProgress() { const alert = document.getElementById(\'taskProgressAlert\'); if (alert) { alert.remove(); }}// 显示错误信息function showError(message) { const errorHtml = `  ${message}  
 `; document.getElementById(\'resultContainer\').insertAdjacentHTML(\'beforebegin\', errorHtml);}

七、部署与安全考虑

7.1 后端代理实现

为了保护API密钥并处理跨域问题，实现一个简单的Node.js代理服务器：

// server.js - Express代理服务器const express = require(\'express\');const axios = require(\'axios\');const cors = require(\'cors\');require(\'dotenv\').config();const app = express();const port = process.env.PORT || 3000;// 中间件app.use(cors());app.use(express.json());// ModelScope API配置const MODEL_SCOPE_BASE_URL = \'https://api-inference.modelscope.cn/\';const API_KEY = process.env.MODELSCOPE_API_KEY;// 通用请求头const commonHeaders = { \"Authorization\": `Bearer ${API_KEY}`, \"Content-Type\": \"application/json\"};// 代理图像生成请求app.post(\'/api/generate\', async (req, res) => { try { const response = await axios.post( `${MODEL_SCOPE_BASE_URL}v1/images/generations`, req.body, { headers: {  ...commonHeaders,  \"X-ModelScope-Async-Mode\": \"true\" } } ); res.json(response.data); } catch (error) { console.error(\'Proxy error:\', error.response?.data || error.message); res.status(error.response?.status || 500).json({ error: error.response?.data?.message || error.message }); }});// 代理任务状态检查app.get(\'/api/tasks/:taskId\', async (req, res) => { try { const response = await axios.get( `${MODEL_SCOPE_BASE_URL}v1/tasks/${req.params.taskId}`, { headers: {  ...commonHeaders,  \"X-ModelScope-Task-Type\": \"image_generation\" } } ); res.json(response.data); } catch (error) { console.error(\'Proxy error:\', error.response?.data || error.message); res.status(error.response?.status || 500).json({ error: error.response?.data?.message || error.message }); }});// 启动服务器app.listen(port, () => { console.log(`Proxy server running on port ${port}`);});

7.2 环境配置与安全实践

创建环境配置文件和安全最佳实践：

// 前端配置const CONFIG = { API_BASE_URL: window.location.hostname === \'localhost\' ? \'http://localhost:3000/api\' : \'/api\', MAX_HISTORY_ITEMS: 20, DEFAULT_PARAMS: { model: \'black-forest-labs/FLUX.1-Krea-dev\', size: \'1024x1024\', steps: 30, guidance: 7.5 }, // 其他配置项...};// 更新API调用以使用代理class SecureModelScopeAPI { static async submitImageGenerationTask(params) { const response = await axios.post( `${CONFIG.API_BASE_URL}/generate`, params ); if (response.data && response.data.task_id) { return response.data.task_id; } else { throw new Error(\'Invalid response format from proxy\'); } } static async checkTaskStatus(taskId) { const response = await axios.get( `${CONFIG.API_BASE_URL}/tasks/${taskId}` ); return response.data; }}

创建环境变量文件(.env)：

MODELSCOPE_API_KEY=your_actual_api_key_herePORT=3000NODE_ENV=production

八、未来功能扩展方向

8.1 模型管理与比较

实现多模型支持与结果比较功能：

// 模型管理类class ModelManager { constructor() { this.availableModels = [ { id: \'black-forest-labs/FLUX.1-Krea-dev\', name: \'FLUX.1\', description: \'高质量的图像生成模型\', supportedSizes: [\'512x512\', \'768x768\', \'1024x1024\'], maxSteps: 100, defaultSteps: 30 }, { id: \'MAILAND/majicflus_v1\', name: \'MajicFLUS v1\', description: \'适用于动漫风格的图像生成\', supportedSizes: [\'512x512\', \'768x768\'], maxSteps: 50, defaultSteps: 25 }, { id: \'qwen-qwen1.5-72b-image\', name: \'Qwen-Image 72B\', description: \'支持多模态输入的大型模型\', supportedSizes: [\'512x512\', \'768x768\', \'1024x1024\', \'1664x1664\'], maxSteps: 100, defaultSteps: 40 } ]; } getModelById(id) { return this.availableModels.find(model => model.id === id); } updateFormForModel(modelId) { const model = this.getModelById(modelId); if (!model) return; // 更新尺寸选项 const sizeSelect = document.getElementById(\'sizeSelect\'); sizeSelect.innerHTML = \'\'; model.supportedSizes.forEach(size => { const option = document.createElement(\'option\'); option.value = size; option.textContent = size; if (size === \'1024x1024\') option.selected = true; sizeSelect.appendChild(option); }); // 更新步数限制 const stepsInput = document.getElementById(\'stepsInput\'); stepsInput.max = model.maxSteps; if (parseInt(stepsInput.value) > model.maxSteps) { stepsInput.value = model.defaultSteps; } // 显示模型信息 this.showModelInfo(model); } showModelInfo(model) { // 创建或更新模型信息面板 let infoPanel = document.getElementById(\'modelInfoPanel\'); if (!infoPanel) { infoPanel = document.createElement(\'div\'); infoPanel.id = \'modelInfoPanel\'; infoPanel.className = \'alert alert-info mt-3\'; document.getElementById(\'imageForm\').appendChild(infoPanel); } infoPanel.innerHTML = ` ${model.name}: ${model.description} 
支持尺寸: ${model.supportedSizes.join(\', \')} | 最大步数: ${model.maxSteps} `; }}// 初始化模型管理const modelManager = new ModelManager();// 模型选择变化时更新表单document.getElementById(\'modelSelect\').addEventListener(\'change\', (e) => { modelManager.updateFormForModel(e.target.value);});// 页面加载时初始化document.addEventListener(\'DOMContentLoaded\', () => { modelManager.updateFormForModel(document.getElementById(\'modelSelect\').value);});

8.2 高级提示词工具

实现提示词建议、模板和效果预览功能：

// 提示词工具类class PromptTools { constructor() { this.templates = [ { name: \'肖像\', prompt: \'portrait of a {subject}, detailed face, professional photography, sharp focus, studio lighting\', negativePrompt: \'blurry, low quality, distorted, watermark\' }, { name: \'风景\', prompt: \'landscape of {subject}, majestic, beautiful lighting, hyperdetailed, photorealistic\', negativePrompt: \'blurry, people, buildings, low resolution\' }, { name: \'动漫\', prompt: \'anime style {subject}, vibrant colors, clean lines, detailed background, official art\', negativePrompt: \'realistic, photorealistic, 3d render, low quality\' } ]; this.suggestions = [ \'masterpiece\', \'best quality\', \'4k\', \'8k\', \'ultra detailed\', \'sharp focus\', \'studio lighting\', \'dramatic lighting\', \'professional photography\' ]; } applyTemplate(templateName, subject) { const template = this.templates.find(t => t.name === templateName); if (!template) return null; return { prompt: template.prompt.replace(\'{subject}\', subject), negativePrompt: template.negativePrompt }; } enhancePrompt(basePrompt) { // 添加一些通用质量提示词（如果尚未包含） const enhanced = basePrompt.split(\',\'); this.suggestions.forEach(suggestion => { if (!basePrompt.toLowerCase().includes(suggestion)) { enhanced.push(suggestion); } }); return enhanced.join(\', \'); }}// 初始化提示词工具const promptTools = new PromptTools();// 添加快捷模板按钮function initPromptTemplates() { const templateGroup = document.createElement(\'div\'); templateGroup.className = \'btn-group w-100 my-2\'; templateGroup.innerHTML = `     `; document.getElementById(\'promptInput\').parentNode.appendChild(templateGroup); // 模板按钮事件 document.querySelectorAll(\'.prompt-template\').forEach(button => { button.addEventListener(\'click\', (e) => { const templateName = e.target.dataset.template; const subject = prompt(`请输入${templateName}的主题:`, \"a beautiful woman\"); if (subject) { const result = promptTools.applyTemplate(templateName, subject); if (result) {  document.getElementById(\'promptInput\').value = result.prompt;  document.getElementById(\'negativePrompt\').value = result.negativePrompt; } } }); }); // 增强提示词按钮 document.getElementById(\'enhancePrompt\').addEventListener(\'click\', () => { const currentPrompt = document.getElementById(\'promptInput\').value; if (currentPrompt) { document.getElementById(\'promptInput\').value = promptTools.enhancePrompt(currentPrompt); } });}// 页面加载时初始化提示词工具document.addEventListener(\'DOMContentLoaded\', initPromptTemplates);
