入門POST變量後，頁面的源代碼已被送往

Question

我有一些代碼，我登錄到Facebook和它儘可能正常工作爲返回我看到您登錄。 之後的頁面，但我想我的請求我登錄後的實際配置文件，而不僅僅是我的新聞提要。 所以我必須將我的電子郵件和密碼發送到登錄頁面，然後請求我的個人資料。 如何在請求我的個人資料時保持登錄數據？

這裏是我有什麼

public static string logIn() 
    { 
     //get the cookies before you try to log in 
     CookieCollection cookies = new CookieCollection(); 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.facebook.com"); 
     request.CookieContainer = new CookieContainer(); 
     request.CookieContainer.Add(cookies); 
     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
     cookies = response.Cookies; 
     response.Close(); 

     //logging in 
     HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create("https://www.facebook.com/login.php?login_attempt=1"); 
     getRequest.CookieContainer = new CookieContainer(); 
     getRequest.CookieContainer.Add(cookies); 
     getRequest.Method = WebRequestMethods.Http.Post; 
     getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2"; 
     getRequest.AllowWriteStreamBuffering = true; 
     getRequest.ProtocolVersion = HttpVersion.Version11; 
     getRequest.AllowAutoRedirect = true; 
     getRequest.ContentType = "application/x-www-form-urlencoded"; 

     //sending the email/password 
     byte[] byteArray = Encoding.ASCII.GetBytes("email=myemail@yahoo.com&pass=mypassword"); 
     getRequest.ContentLength = byteArray.Length; 
     Stream newStream = getRequest.GetRequestStream(); 
     newStream.Write(byteArray, 0, byteArray.Length); 
     newStream.Close(); 

     //returns the source of the page after logging in 
     HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse(); 
     StreamReader sr = new StreamReader(getResponse.GetResponseStream()); 
     string source = sr.ReadToEnd(); 
     cookies.Add(getResponse.Cookies); 

     //tries to get my profile source 
     //everything works fine until here 
     getRequest = (HttpWebRequest)WebRequest.Create("http://www.facebook.com/myprofile"); 
     getRequest.CookieContainer = new CookieContainer(); 
     getRequest.CookieContainer.Add(cookies); 
     getRequest.Method = WebRequestMethods.Http.Get; 
     getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2"; 
     getRequest.AllowWriteStreamBuffering = true; 
     getRequest.ProtocolVersion = HttpVersion.Version11; 
     getRequest.AllowAutoRedirect = true; 
     getRequest.ContentType = "application/x-www-form-urlencoded"; 

     getResponse = (HttpWebResponse)getRequest.GetResponse(); 
     sr = new StreamReader(getResponse.GetResponseStream()); 
     source = sr.ReadToEnd(); 
     getResponse.Close(); 
     return source; 
    } 

我試着這樣做的幾種方法，我得到它回到我的個人資料，但它返回它，就好像我不是在和你登錄實際上無法查看我的個人資料（因爲它設置爲私密） 所以我需要我的登錄信息以某種方式包含在請求我的個人資料時。

Answer 1

你必須在一開始啓動CookieCollection，並用它爲所有請求。 CookieCollection每當您執行請求時都使用新的cookie進行更新，因此使用cookies.Add（）也會將其搞亂。 但我現在工作的很好。

Answer 2

這讓我難住了一段時間，當我做類似的東西。你需要確保你設置適當的餅乾爲您的要求你登錄後，試着將它們應用到你的最後一個請求之前添加新的cookie來CookieCollection對象。

//^previous code^
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse(); 
StreamReader sr = new StreamReader(getResponse.GetResponseStream()); 
string source = sr.ReadToEnd(); 

Uri facebookPage = new Uri("http://www.facebook.com"); // .GetCookies() only accepts a Uri 
cookies.Add(request.CookieContainer.GetCookies(facebookPage)); 

getResponse.Close(); // Always make sure you close your responses 

// V requesting your profile code V
