使用HttpWebRequest 的post方法传递参数，但抓包抓不到信息

Laura2333 2016-09-20 08:00:40

我想使用使用HttpWebRequest 的post方法模拟登陆一个网页



byte[] bs = Encoding.UTF8.GetBytes(loginData);

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(loginUrl);

webRequest.Method = "POST";

webRequest.ContentType = "application/x-www-form-urlencoded";

webRequest.ContentLength = bs.Length;

webRequest.ServicePoint.Expect100Continue = false;

webRequest.KeepAlive = false;

webRequest.Timeout = 3000;

webRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.2; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1667.0 Safari/537.36";

Stream reqStream = webRequest.GetRequestStream();

 reqStream.Write(bs, 0, bs.Length);

 reqStream.Close();

WebResponse WebResponse = webRequest.GetResponse();

StreamReader reader = new StreamReader(WebResponse .GetResponseStream(), Encoding.Default);

string content = reader.ReadToEnd();

Console.Write(content);

 WebResponse.Close();

但是抓到的包里没有我想要传递的信息

但是用正常浏览器登陆就有。是怎么回事啊

还是不行，用的是wireshark
