使用WebClient或HttpWebRequest登錄

Iam登錄遇到嚴重問題。我不能使用WebBrowser類登錄到網站，因爲WebBrowser只是單線程類。我無法使用WebClient登錄，因爲我沒有Cookie。試着用HttpWebRequest和蔭猜我成功地登錄，因爲我得到了與頭登入：login.success或類似的東西，但是當我retreived源頁面，它返回我登錄頁顯示我蔭沒有登錄。使用WebClient或HttpWebRequest登錄

蔭嘗試登錄此頁面：https://lite.betfair.com/Login.do?s=000009z

網址的請求： https://lite.betfair.com/SLoginsubmit.do?s=000009z&secure=true&username=user&password=pass

代碼：

HttpWebRequest request; 
HttpWebResponse response; 
CookieContainer cookies; 
string url = "https://lite.betfair.com/SLoginsubmit.do?s=000009z&secure=true&username=user&password=pass"; 
request = (HttpWebRequest)WebRequest.Create(url); 
request.AllowAutoRedirect = false; 
request.CookieContainer = new CookieContainer(); 
response = (HttpWebResponse)request.GetResponse(); 
cookies = request.CookieContainer; 
response.Close(); 

request = (HttpWebRequest)WebRequest.Create("https://lite.betfair.com/Events.do?s=000209z"); 
request.AllowAutoRedirect = false; 
request.CookieContainer = cookies; 
response = (HttpWebResponse)request.GetResponse(); 

using (Stream s = response.GetResponseStream()) 
{ 
    StreamReader sr = new StreamReader(s); 
    string line; 

    line = sr.ReadToEnd(); 
}

這聽起來像你沒有將cookie從登錄響應傳遞到下一個請求。發佈你的代碼，我們會幫你弄清楚。 – 2012-02-17 22:42:15
