[JavaScript] 最近百度云盘不提供搜索,闲来无事,玩玩python爬虫,爬一下百度云盘的资源

  最近百度云盘不知道为啥不提供资源检索,正好最近看了一下python,正好来练练手,写歌爬虫爬一下百度云盘的资源。    分析了一下百度云盘的网友源码和js文件,里面有大量ajax的东西,利用json传输数据,前端显示。话说,这样数据爬去就方便多了,也不要用scrapy啥的,直接解析json数据就好。    分析js文件提炼了下面三个链接:
  
URL_SHARE = 'http://yun.baidu.com/pcloud/feed/getsharelist?auth_type=1&start={start}&limit=20&query_uk={uk}&urlid={id}'
URL_FOLLOW = 'http://yun.baidu.com/pcloud/friend/getfollowlist?query_uk={uk}&limit=20&start={start}&urlid={id}'http://yun.baidu.com/pcloud/friend/getfanslist?query_uk=1327787586&limit=25&start=0
URL_FANS = 'http://yun.baidu.com/pcloud/friend/getfanslist?query_uk={uk}&limit=20&start={start}&urlid={id}'
整个数据爬取流程起到很重要的作用。  爬虫分三步,一个是urlids 保存要爬取的网址,一个是user存放用户uk,另一个是share存放user分享的数据,包含任何你想要的数据。  下面提供三个核心函数代码:
