在WebBrowser中使用WebRequest cookie

Question

我想使用WebRequest登錄網站，稍後在WebBrowser中顯示網站（記錄）。

但如何「複製」WebRequest cookie到WebBrowser？

由於提前，

使用Cookie集合搶餅乾，這個月我已經寫類似的東西，我可以分享你一些示例代碼：

static string GetFromServer(string URL, ref CookieCollection oCookie) 
    { 
     //first rquest 
     // Create a request for the URL. 
     HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL); 
     request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"; 
     request.AllowAutoRedirect = false; 
     // If required by the server, set the credentials. 
     //request.Credentials = CredentialCache.DefaultCredentials; 
     request.CookieContainer = new CookieContainer(); 
     if (oCookie != null) 
     { 
      foreach (Cookie cook in oCookie) 
      { 
       request.CookieContainer.Add(cook); 
      } 
     } 

     // Get the response. 
     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
     foreach (Cookie cook in response.Cookies) 
     { 
      oCookie.Add(cook); 
     } 
     // Display the status. 
     while (response.StatusCode == HttpStatusCode.Found) 
     { 
      response.Close(); 
      request = (HttpWebRequest)HttpWebRequest.Create(response.Headers["Location"]); 
      request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"; 
      request.AllowAutoRedirect = false; 
      request.CookieContainer = new CookieContainer(); 
      if (oCookie != null) 
      { 
       foreach (Cookie cook in oCookie) 
       { 
        request.CookieContainer.Add(cook); 
       } 
      } 
      response = (HttpWebResponse)request.GetResponse(); 
      foreach (Cookie cook in response.Cookies) 
      { 
       oCookie.Add(cook); 
      } 
     } 
     Console.WriteLine(((HttpWebResponse)response).StatusDescription); 
     // Get the stream containing content returned by the server. 
     Stream dataStream = response.GetResponseStream(); 
     // Open the stream using a StreamReader for easy access. 
     StreamReader reader = new StreamReader(dataStream); 
     // Read the content. 
     string responseFromServer = reader.ReadToEnd(); 
     // Display the content. 
     Console.WriteLine(responseFromServer); 
     // Clean up the streams and the response. 
     reader.Close(); 
     response.Close(); 
     return responseFromServer; 
    } 

現在你得到餅乾，你只需要將其設置爲webBrowser控件，導入此方法：

[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] 
    public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData); 

以後你叫這讓餅乾：

string cookie_string = string.Empty; 
     foreach (Cookie cook in cookieCon) 
     { 
      cookie_string += cook.ToString() + ";"; 
      InternetSetCookie(url, cook.Name, cook.Value); 
     } 
     webBrowser1.Navigate(url, "", null, "Cookie: " + cookie_string + Environment.NewLine); 

請注意，這僅僅是我的測試代碼，主要是從MSDN複製，因此它可能馬車，你可能需要更多的異常處理
