上次说到怎么获取BAIDUID,这个相信很多人都能够拿到就不多说了,今天一连说两个,获取token和raskey 2、利用以上获得的cookie直接访问页面
在第一篇文章中写到这个,拿着我们储存到的BAIDUID直接请求这个页面,就能够获取到反馈回来的Json格式的数据
这里的话需要用到一个dll,添加引用到项目【Newtonsoft.Json】
至于这个文档怎么用,已经有其他前辈的博文中说到,我这里就不解释了,如果不懂的可以在后面看代码
如果你拿不到token,那么只有一个问题,你没有BAIDUID,如果你确认第一次是收集到了,那么请重复检验在请求token时这个Cookies是否还存在。(很多时候是Cookies的效期问题导致Cookies收集器将失效的BAIDUID自动丢弃)
有了前面的步骤,拿到raskey也就很简单了,步骤是一样的,将前面所有的Cookies都保存下来,接下来
3、用token访问该地址,获取raskeyhttps://passport.baidu.com/v2/getpublickey?token=5d0fc87cb0de39982c06795d3356e239&tpl=zongheng&apiver=v3&tt=1441311621601&gid=59723A6-1178-4614-B7AF-779917BC4453&callback=bd__cbs__gaci47和publickey,注意将地址中的值替换。
很明显,你会发现反馈回来的也是一个Json数据,但可以看到后面有一串以-----BEGIN PUBLIC KEY----- 开头以----End Public KEY----结尾的数据,那里面就是publickey,而紧跟在后的key后的字符串就是raskey,用上面同样的办法拿到这两组数据,切记前一组要将开头和结尾的标识字符串也要截取出来,而不是单纯的乱字符串。
现在算一下我们拿到的东西:3个页面的Cookies、token、publickey、raskey
这几个都齐全了,那么就可以向百度提交post请求登录,但在这之前,你需要准备一串经过ras加密过后的密码,否则会一直提示密码错误,也就是err_7。
这块需要添加另外一个引用【BouncyCastle.Crypto.dll】这是哪个大神写的就不清楚了,但非常实用,很感谢这些大神做出的贡献。之后添加一个类:
