登录和发送消息后如何保持授权？

这是我的代码：

for (var i = 0; i < Listchat.Length; i++)
{
    string url = Listchat[i] + "/ajax/";
    string par = "act=login&chat=" + "4952" + "&msg=" + log + "&pass=" + pass + "&remember=0&pv=0&c=&bind=0";

    HttpWebRequest request3 = (HttpWebRequest)WebRequest.Create(url);
    request3.CookieContainer = cookieJar;
    request3.UserAgent = "Opera/9.80";
    request3.Method = "POST";
    request3.ContentType = "application/x-www-form-urlencoded";
    byte[] EncodedPostParams3 = Encoding.Default.GetBytes(par);
    request3.ContentLength = EncodedPostParams3.Length;
    request3.GetRequestStream().Write(EncodedPostParams3, 0, EncodedPostParams3.Length);
    request3.GetRequestStream().Close();
    request3.AllowAutoRedirect = false;
    HttpWebResponse response = (HttpWebResponse)request3.GetResponse();


    //SEND MESSAGE!!   Here the message is sent to the chat only 1 time and lost authorization


    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Listchat[i] + "/ajax/?act=send&chat=" +"4952" + "&channel=main&pv=0&msg=" + mess + "");
    req.CookieContainer = cookieJar;
    req.Timeout = 20 * 60 * 1000;
    req.KeepAlive = true;
    HttpWebResponse respons = (HttpWebResponse)req.GetResponse();
    Stream dataStream = respons.GetResponseStream();
    StreamReader reader = new StreamReader(dataStream);
    string responseFromServer = reader.ReadToEnd();
    reader.Close();
    dataStream.Close();
    respons.Close();
    label2.Text = responseFromServer;
}

您需要一种将 cookie 从响应传递到下一个请求的方法。问题是它们没有在请求之间持续存在。如果您创建 aCookieContainer和 a CookieCollection，您可以从响应中收集 cookie 并将它们添加到CookieContainer. 以下是一些演示此方法的修改代码： 

CookieContainer container = new CookieContainer();
CookieCollection cookies = new CookieCollection();

for (var i = 0; i < Listchat.Length; i++)
{
    string url = Listchat[i] + "/ajax/";
    string par = "act=login&chat=" + "4952" + "&msg=" + log + "&pass=" + pass + "&remember=0&pv=0&c=&bind=0";

    HttpWebRequest request3 = (HttpWebRequest)WebRequest.Create(url);
    request3.CookieContainer = container;
    request3.CookieContainer.Add(cookies);
    request3.UserAgent = "Opera/9.80";
    request3.Method = "POST";
    request3.ContentType = "application/x-www-form-urlencoded";
    byte[] EncodedPostParams3 = Encoding.Default.GetBytes(par);
    request3.ContentLength = EncodedPostParams3.Length;
    request3.GetRequestStream().Write(EncodedPostParams3, 0, EncodedPostParams3.Length);
    request3.GetRequestStream().Close();
    request3.AllowAutoRedirect = false;
    HttpWebResponse response = (HttpWebResponse)request3.GetResponse();
    cookies = response.Cookies;


    //SEND MESSAGE!!   Here the message is sent to the chat only 1 time and lost authorization


    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Listchat[i] + "/ajax/?act=send&chat=" +"4952" + "&channel=main&pv=0&msg=" + mess + "");
    req.CookieContainer = container;
    req.CookieContainer.Add(cookies);
    req.Timeout = 20 * 60 * 1000;
    req.KeepAlive = true;
    HttpWebResponse respons = (HttpWebResponse)req.GetResponse();
    cookies = respons.Cookies;
    Stream dataStream = respons.GetResponseStream();
    StreamReader reader = new StreamReader(dataStream);
    string responseFromServer = reader.ReadToEnd();
    reader.Close();
    dataStream.Close();
    respons.Close();
    label2.Text = responseFromServer;
}
