网友: 技术文档 2025-08-08 00:20:26

🔍 1. 测试准备阶段

1.1 环境预检

# env_check.pyimport platform, socket, subprocessdef system_info(): print(f\"{\'=\'*40}\") print(f\"🖥️ 系统信息\".center(40)) print(f\"操作系统\\t{platform.system()} {platform.release()}\") print(f\"主机名\\t{socket.gethostname()}\") print(f\"Python\\t{platform.python_version()}\") def network_info(): print(f\"\\n{\'=\'*40}\") print(f\"🌐 网络配置\".center(40)) subprocess.run([\"ipconfig\", \"/all\"] if platform.system() == \"Windows\" else [\"ifconfig\"]) system_info()network_info

1.2 工具矩阵

工具类别 Windows安装命令 Linux安装命令 核心功能 带宽测试 choco install iperf3 sudo apt install iperf3 网络吞吐量测量 端口扫描 choco install nmap sudo apt install nmap 服务发现与漏洞检测 流量分析 choco install wireshark sudo apt install wireshark 数据包捕获与分析 高级Ping Install-Module PsPing sudo apt install fping 精确延迟测量

🧪 2. 基础测试套件

2.1 增强版Ping测试

# ping_advanced.ps1$targets = @( \"gateway\", \"114.114.114.114\", \"8.8.8.8\", \"www.baidu.com\")$results = foreach ($t in $targets) { $ping = Test-Connection -TargetName $t -Count 10 -ErrorAction SilentlyContinue [PSCustomObject]@{ Target = $t AvgLatency = ($ping.ResponseTime | Measure-Object -Average).Average PacketLoss = (10 - $ping.Count)/10*100 }}$results | Format-Table -AutoSize$results | Export-Csv -Path \"ping_results.csv\" -NoTypeInformation

2.2 智能端口扫描

# port_scanner.pyimport socketfrom concurrent.futures import ThreadPoolExecutordef scan_port(host, port): try: with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.settimeout(2) result = s.connect_ex((host, port)) return port, result == 0 except Exception as e: return port, f\"Error: {str(e)}\"def full_scan(host, ports=range(1, 1025)): with ThreadPoolExecutor(max_workers=100) as executor: results = executor.map(lambda p: scan_port(host, p), ports) for port, status in results: if status is True: print(f\"✅ Port {port}: OPEN\") elif \"Error\" not in str(status): print(f\"❌ Port {port}: CLOSED\")if __name__ == \"__main__\": full_scan(\"target.example.com\")

🚀 3. 进阶测试方案

3.1 全方位带宽压测

# bandwidth_test.sh#!/bin/bashSERVER_IP=\"192.168.1.100\"DURATION=60THREADS=10echo \"🔄 启动iPerf3服务端...\"iperf3 -s -p 5201 &echo \"⏳ 进行TCP上行测试...\"iperf3 -c $SERVER_IP -t $DURATION -P $THREADS -J > tcp_upload.jsonecho \"⏳ 进行TCP下行测试...\"iperf3 -c $SERVER_IP -t $DURATION -P $THREADS -R -J > tcp_download.jsonecho \"⏳ 进行UDP测试...\"iperf3 -c $SERVER_IP -t $DURATION -u -b 1G -J > udp_test.jsonecho \"📊 生成测试报告...\"python3 generate_report.py tcp_upload.json tcp_download.json udp_test.jsonpkill iperf3

3.2 智能流量分析

# 关键过滤条件库/* 基础过滤 */icmp || dns || tcp.port == 80 || tcp.port == 443/* 异常检测 */tcp.analysis.retransmission || tcp.analysis.duplicate_ack || tcp.analysis.zero_window/* 应用层分析 */http.request.method == \"POST\" || ssl.handshake.type == 1 || dns.qry.name contains \"api\"

🛠️ 4. 深度问题排查

4.1 网络路径诊断

# network_path.ps1function Trace-NetworkPath { param ( [string]$Target, [int]$MaxHops = 30, [int]$Timeout = 1000 ) $results = tracert -d -h $MaxHops -w $Timeout $Target | Where-Object { $_ -match \"\\d+\\s+ms\" } | ForEach-Object { $parts = $_ -split \"\\s+\" [PSCustomObject]@{ Hop = $parts[0] IP = $parts[-2] Latency = $parts[-3..-1] -join \"/\" } } $results | Export-Csv -Path \"tracert_$Target.csv\" -NoTypeInformation return $results}Trace-NetworkPath -Target \"www.example.com\" -MaxHops 15

4.2 综合连接测试

# connection_test.pyimport pycurlfrom io import BytesIOdef test_endpoint(url): buffer = BytesIO() c = pycurl.Curl() c.setopt(c.URL, url) c.setopt(c.WRITEDATA, buffer) c.setopt(c.TIMEOUT, 10) metrics = {} c.setopt(c.WRITEHEADER, lambda h: metrics.update({ \'http_code\': c.getinfo(c.HTTP_CODE), \'connect_time\': c.getinfo(c.CONNECT_TIME), \'total_time\': c.getinfo(c.TOTAL_TIME) })) try: c.perform() return { \'status\': \'success\', \'metrics\': metrics, \'response\': buffer.getvalue().decode() } except Exception as e: return { \'status\': \'failed\', \'error\': str(e) } finally: c.close()print(test_endpoint(\"https://www.baidu.com\"))

🤖 5. 自动化运维方案

5.1 智能监控系统

# network_monitor.pyimport scheduleimport timeimport jsonfrom datetime import datetimeclass NetworkMonitor: def __init__(self): self.config = self.load_config() def load_config(self): with open(\'config.json\') as f: return json.load(f) def run_tests(self): test_results = {} for test in self.config[\'tests\']: # 执行各类测试... test_results[test[\'name\']] = self.execute_test(test) self.generate_report(test_results) def execute_test(self, test_config): # 实现具体测试逻辑 pass def generate_report(self, results): filename = f\"report_{datetime.now().strftime(\'%Y%m%d_%H%M%S\')}.html\" # 生成报告... print(f\"报告已生成: {filename}\")if __name__ == \"__main__\": monitor = NetworkMonitor() schedule.every(15).minutes.do(monitor.run_tests) while True: schedule.run_pending() time.sleep(1)

5.2 可视化报告模板

 网络测试报告 - {<!-- -->{ date }}  .dashboard { display: grid; grid-template-columns: repeat(3, 1fr); gap: 20px; } .metric-card { border: 1px solid #ddd; padding: 15px; border-radius: 5px; } .critical { background-color: #ffebee; }  
网络健康报告
 
 {% for test in tests %} 
 
{{ test.name }}
 
状态: {{ test.status }}
 
延迟: {{ test.latency }} ms
 
时间: {{ test.timestamp }}
 
 {% endfor %}
