Answer 1

            string url = "http://wappass.baidu.com/passport/";
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            string postData = "login_username=" + textBox1.Text + "&login_loginpass=" + textBox2.Text + "&aaa=%E7%99%BB%E5%BD%95&login=yes&can_input=0&u=&login_start_time=1359431843&tpl=&tn=&pu=&ssid=&from=&bd_page_type=&uid=1359431843588_646&login_username_input=0&type=";
            byte[] byteRequest = Encoding.Default.GetBytes(postData);
            request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.CookieContainer = cookieContainer;
            request.Referer = url;
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = byteRequest.Length;  //附加信息长度
            request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:18.0) Gecko/20100101 Firefox/18.0";
            request.Method = "POST";            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream stream = response.GetResponseStream();  //转换为数据流
            StreamReader reader = new StreamReader(stream);
            string html = reader.ReadToEnd();   //通过StreamReader类读取流
            html = richTextBox1.Text;
            reader.Close();
            stream.Close();

Answer 2

这里有指定:request.ContentLength = byteRequest.Length;  //附加信息长度但是你没有Stream.Writer        Steam.Write(byteRequest, 0, byteRequest.Length);请自行调试将该代码加入到正确位置.

Answer 3

string url = "http://wappass.baidu.com/passport/";
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            string postData = "login_username=" + textBox1.Text + "&login_loginpass=" + textBox2.Text + "&aaa=%E7%99%BB%E5%BD%95&login=yes&can_input=0&u=&login_start_time=1359431843&tpl=&tn=&pu=&ssid=&from=&bd_page_type=&uid=1359431843588_646&login_username_input=0&type=";
            byte[] byteRequest = Encoding.Default.GetBytes(postData);
            request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.CookieContainer = cookieContainer;
            request.Referer = url;
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = byteRequest.Length;  //附加信息长度
            request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:18.0) Gecko/20100101 Firefox/18.0";
            request.Method = "POST";
            Stream newStream = request.GetRequestStream();
            // Send the data.
            newStream.Write(byteRequest, 0, byteRequest.Length);
            newStream.Close();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.Default);
            string html = reader.ReadToEnd();   //通过StreamReader类读取流
            html = richTextBox1.Text;
            reader.Close();
            stream.Close();

Answer 4

1.url 和 Request 定义出现混乱。2.没有写入POST 的数据。

Answer 5

你定义url的位置不对吧。要放在上面啊，
而且你定义了2次request了

Answer 6

個人建議HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); 這語句出現了兩次把第一次的刪掉就可以了
