在心力憔悴的时候，绝处逢生！搞了几天，成功了，哈哈哈啊哈哈！

# 模拟新浪微博登录的完整请求过程，包括预登录，重定向，和最后返回个人主页；
# 该项目的难点再与破解js加密的post数据，在此基础上，还需要多次对服务器发起多个请求，
# 完整的流程走下来，微博才鞥够成功的登录上
# 整体的框架梳理： 全程用session保存cookie 哦
# 第一：通过抓包可以发现，我们在登录微博首页的时候，客户端向服务器发起的请求并不是首页的地址，而是/vistor/vistor
# 为了全真模拟，那么我们也必须先请求这个地址，然后再；
# 第二：请求微博的首页，似乎没什么意思，就是要走这个流程，也许不需要，代码还没有优化；
# 第三：预登录，这一步就很重要了，因为在后面的post登录请求中会有很多的表单数据，预登录的响应信息有很多我们想要的；
# 第四：找到加密password等数据的加密js，在js中找到加密的方式，破解加密；
# 第五：发起post登录请求；
# 第六：发起多次的重定向请求
# 第七：打开个人首页，到此便大功告成；perfect！！！！！
