Question

下面代码很简单 就是post 数据包登陆。。但是不知道是不是我的包有问题。还是怎么回事。总是超时public string OpenReadWithHttps(string URL, string strPostdata, string strEncoding)
   {
   try
   {
   Encoding encoding = Encoding.Default;
   HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
   request.Method = "post";

   buffer = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
   //设置请求的ContentLength    //byte[] buffer = encoding.GetBytes(strPostdata);
   request.ContentLength = buffer.Length;
   request.GetRequestStream().Write(buffer, 0, buffer.Length);
   HttpWebResponse response = (HttpWebResponse)request.GetResponse();

   return "";
   }///调用
   protected void Button1_Click(object sender, EventArgs e)
   {
   OpenReadWithHttps("http://new.cnzz.com/user/login.php",

  }

Answer 1

使用Firefox的LiveHTTPHeaders 插件，查看提交的url和表单名称

Answer 2

 我都看过了 
url  ("http://new.cnzz.com/user/login.php",请求的内容 [email protected]&password=123456&list=1&submit.x=92&submit.y=19 
我组织的包也是这样的。。

Answer 3

(HttpWebRequest)WebRequest.Create(URL+paraUrlCoded)

Answer 4

 public void doPost(String url, String payload) 
    {
        WebRequest req = WebRequest.Create(url);
        req.Method = "POST";
        req.ContentType = "text/plain; charset=utf-8";        // Encode the data
        byte[] encodedBytes = Encoding.UTF8.GetBytes(payload);
        req.ContentLength = encodedBytes.Length;        // Write encoded data into request stream
        Stream requestStream = req.GetRequestStream();
        requestStream.Write(encodedBytes, 0, encodedBytes.Length);
        requestStream.Close();        WebResponse result = req.GetResponse();
        
    }

request.CookieContainer = cookieContainer;
request.ContentLength = postData.Length;// 提交请求数据 
System.IO.Stream outputStream = request.GetRequestStream();
outputStream.Write(postData, 0, postData.Length);
outputStream.Close();HttpWebResponse response;
Stream responseStream;
StreamReader reader;
string srcString;
response = request.GetResponse() as HttpWebResponse;
responseStream = response.GetResponseStream();
