Поддерживать авторизацию между HttpWebRequests

Question

Как сохранить авторизацию после входа в систему и отправки сообщений?

Вот мой код:

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; 
}

Вам нужен способ передачи печенья из ответа на следующий запрос. Проблема в том, что они не сохраняются между запросами. Если вы создадите CookieContainer и CookieCollection, вы можете собрать куки-файлы из ответа и передать их следующему запросу, добавив их в CookieContainer. Вот какой-то модифицированный код, демонстрирующий такой подход:

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; 
}
