BAIDUID: 21447B391F8874869C7BFFD4B51D8474:FG=1 2、利用以上获得的cookie直接访问页面 /v2/api/?getapi&tpl=zongheng&apiver=v3&tt=1441287460704&class=login&gid=26D2A76-9D6C-4EBE-8687-25C6591194B2&logintype=basicLogin&callback=bd__cbs__v9tdyy获取参数token 注：tt是一个时间戳，用以下方法生成 /// <summary>/// 获取时间戳/// </summary> public string GetTimeStamp() { TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0); return Convert.ToInt64(ts.TotalSeconds).ToString(); } 3、用token访问该地址，获取raskey/v2/getpublickey?token=5d0fc87cb0de39982c06795d3356e239&tpl=zongheng&apiver=v3&tt=1441311621601&gid=59723A6-1178-4614-B7AF-779917BC4453&callback=bd__cbs__gaci47和publickey 4、利用rsa加密算法将密码加密（公钥：publickey） var pemToXml = RsaHelper.PemToXml(result_publicKey.Pubkey); pwd = RsaHelper.RSAEncrypt(pemToXml, pwd); 5、检验是否需要验证码 百度登录有一点比较好，就是他生成验证码会有一个codetype，而且这个type同一个BAIDUID申请是不变的，服务器会根据这个申请的type提供一个codestring，也就是验证码（我们是看不懂的，这个需要我们提交给服务器让它自动解析，就可以获得验证码图片） 6、提交数据登录
如果返回的Json数据显示err_0，即代表成功登陆，257为验证码错误，7为密码错误
7、获得百度提供的BDUSS，即可到想去的网站继续进行下一步分析
上面写的是编写软件时的大概步骤详细步骤，具体步骤后面会继续更新，希望能够帮助到各位有需要的童鞋~欢迎各位评论交流
PS：模拟登录最重要的步骤是抓包分析，获取对应的Cookies，如果遇上问题，请先检查代码逻辑，看看是否已经获得网站需要提供Cookie（有些不是必要的可以不传）
