一点小的注释:
整个流程为: 1 获取代理 ->2 访问首页 —>3 获取首页博客列表,随机访问->4随机等待N秒 ->返回第1步
1:你需要更改youproxyip为你一个你已经拥有的代理ip,或者,不用填写,因为后边的use_proxy=False, 这个时候你确保你能够不适用代理访问到代码中的两个自动抓取代理ip地址的网站
2:/home/bin/phantomjs 这个路径是你安装的phantomjs路径
3:代码中有两个获取代理的方法,例子中选择了一个(不要喷我下边的循环为什么是一次还要循环,因为这个版本是原来是有外层循环的)
4: 获取免费代理地址就不写了,url1 ,url2 为隐藏的获取免费代理的网站
