有道翻译js逆向+GUI
学完js逆向之后，
重新修改了原有的py文件，
发表记录一下 <(￣︶￣)↗[GO!]
第一步，
设置GUI界面
import requestsimport execjsimport timeimport randomfrom tkinter import Tk, Button, Label, Text, ENDclass App(object): def __init__(self): self.root = Tk() # 此处保留 u 转义 # 相信挺多人都忘了这玩意吧 self.root.title(u'有道翻译') self.win() self.Button_func() self.root.mainloop() def win(self): # 设置居中窗口 self.screen_width = self.root.winfo_screenwidth() self.screen_height = self.root.winfo_screenheight() x = (self.screen_width - 310) / 2 y = (self.screen_height - 400) / 2 self.root.geometry("310x400+%d+%d" % (x, y)) # 禁止修改窗体 self.root.resizable(width=False,height=False) # 设置主要的框架 def Button_func(self): # 设置翻译输入框 self.input_text = Text(self.root, background='light blue') self.input_text.place(x=10, y=5, width=285, height=140) self.input_text.bind("", self.submit) # 设置按钮功能 self.submit_btn = Button(self.root, text=u'翻译', command=lambda: self.submit(self)) self.submit_btn.place(x=205, y=155, width=35, height=25) self.clear_btn = Button(self.root, text=u'清空', command=self.clean) self.clear_btn.place(x=250, y=155, width=35, height=25) # 设置结果输出框 self.result_label = Label(self.root, text=u'翻译结果:') self.result_label.place(x=10, y=155) self.out_text = Text(self.root, background='light blue') self.out_text.place(x=10, y=190, width=285, height=200) # 提交事件 def submit(self, event): # 获取输入框的文本 e = self.input_text.get(0.0, END).strip().replace("\n", " ") # 调用爬虫函数 self.translate(e) self.out_text.delete(0.0, END) self.out_text.insert(END, self.tgt) self.out_text.insert(END, "\n"*2) self.out_text.insert(END, self.result) # 清空事件 def clean(self): self.input_text.delete(0.0, END) self.out_text.delete(0.0, END)if __name__ == "__main__": App()
第二部，
使用经js加密后的参数来进行请求，
从返回的结果中提取想要的数据
注：安装能够调用js的库
pip install pyexecjs
而调用是：import execjs
def translate(self, e): # 实例化对象 node = execjs.get() # 读取js文件 js = node.compile(open(r"C:\Users\Administrator\Desktop\name\youdao.js", encoding="utf-8").read()) # 设置其他参数 r = str(int(time.time() * 1000)) i = r + str(int(random.random() * 10)) # 设置js调用方法 func_name = f"getSign('{e}','{i}')" # 调用js文件 sign = js.eval(func_name) # 开始请求 headers = { "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.106 Safari/537.36", "Referer": "http://nmt.youdao.com/", "cookie": "OUTFOX_SEARCH_USER_ID=1287319030@10.169.0.83; OUTFOX_SEARCH_USER_ID_NCOO=2092607892.1324136; JSESSIONID=aaa2DvJCf-1A_7eOhENWx; ___rl__test__cookies=1632757888248", } data = {'i': e, 'from': 'AUTO', 'to': 'AUTO', 'smartresult': 'dict', 'client': 'fanyideskweb', 'salt': i, 'sign': sign, 'lts': r, 'bv': '679a714475741baa9769e4725c532bb7', 'doctype': 'json', 'version': '2.1', 'keyfrom': 'fanyi.web', 'action': 'FY_BY_REALTlME'} res = requests.post( "http://nmt.youdao.com/translate_o?smartresult=dict&smartresult=rule", headers=headers, data=data).json() # 输出框的翻译 self.tgt = res['translateResult'][0][0]['tgt'] self.result = "" # 单词翻译详解,句子没有这个部分 try: for word in res['smartResult']['entries']: self.result += word except: self.result = ""
看完点个赞呗 ！！！
js教学
通过多次翻译单词可以发现，有以下几个参数是变量：
猜测：i 为翻译的内容，salt应该为时间戳，sign的加密类型可能是md5
通过ctrl+shift+F 搜索，sign为加密的主体，通过搜索会得到以下内容
结果只有一条min.js，点击方框里的大括号，就能清晰的看到里面的源码。
通过ctrl+F再次搜索sign，有15个结果，对你怀疑的对象打上断点（通过点击下图里8391位置打上断点），之后重新翻译一下单词，就可以把进程停止在该断点的位置。
选中变量后的整个代码块就会显示该值，该值和header里找到sign值的类型类似，
即该变量就是你要找的数据
选中n.md5 会显示一个函数，点击就能进入到该函数，对数据进行拷贝
依次对salt进行搜索，可以知道salt的值为：r （当前时间戳）+i （ [0,10)区间的一位数）
对所需的js数据拷贝、处理，写入 .js的文件里
大致的思路和流程就是这样！
对于md5加密（常见加密的类型还有好几种）可以自己编写也可以直接拷贝
