【爬虫】Python3搜索并获取电影网站的迅雷下载链接

用到的python第三方库：bs4、requests、execjs（在python中调用js脚本）

目标网站: www.beiwo.tv

通过分析网页源码发现，网页通过调用一个加密JS脚本来加密网页源码中的一段字符串从而获得迅雷电影链接，将分析网页得到的JS加密源码存放到encode.js文件中，通过exejs库在python中调用并传递我们抓取到的待加密的字符串从而获得想要得到的电影迅雷下载链接。

抓包可以分析出网页搜索所发送的表单，构造data表单，向网页发送请求获得搜索网页url，然后按照上面所说解析网页获得待加密字符串。

源码如下：

 1 #ThunderUrl.py
 2 import execjs
 3 def echoDown(str):
 4     #获得未编码的迅雷链接
 5     gurl = []
 6     s = str.split("###")
 7     for i in range(0,len(s)-1):
 8         gurl = s[i].split("$")
 9     return gurl[1]
10 
11 def getJs():
12     #生成JS脚本对象
13     f = open("encode.js", 'r')
14     line = f.readline()
15     htmlstr = ''
16     while line:
17         htmlstr = htmlstr + line
18         line = f.readline()
19     return htmlstr
20
