獲取臉書用戶令牌

我試圖通過這樣檢索Facebook用戶令牌。我知道它可以在Python中完成。獲取臉書用戶令牌

public string GetToken(string Username, string Password) 
    { 
     wb.DownloadData("https://login.facebook.com/login.php?login_attempt=1"); 
     var data = new NameValueCollection(); 
     data["email"] = UserName; 
     data["pass"] = Password; 
     byte[] responsebytes = wb.UploadValues("https://login.facebook.com/login.php?login_attempt=1", "POST", data); 
     string responsebody = Encoding.UTF8.GetString(wb.("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token")); 
     Console.WriteLine(responsebody); 

     return responsebody; 
    }

但它沒有返回令牌。我知道這是可以做到的，因爲我已經在python中看到過它。也有一個簡單的方法從這裏獲取用戶ID？

編輯：

這是它是如何在python完成：

def get_token(self, username, password): 
    self.session.get("https://login.facebook.com/login.php?login_attempt=1") 
    self.session.post("https://login.facebook.com/login.php?login_attempt=1", data={'email': username, 'pass': password})  
    return self.session.get("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token").url.split("=")[1].split("&")[0]

好遠我來此。

 //Login to facebook. 
     string formUrl = "https://login.facebook.com/login.php?login_attempt=1"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag 
     string formParams = string.Format("email_address={0}&password={1}", email, pass); 
     string cookieHeader; 
     HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl); 
     req.ContentType = "application/x-www-form-urlencoded"; 
     req.Method = "POST"; 
     byte[] bytes = Encoding.ASCII.GetBytes(formParams); 
     req.ContentLength = bytes.Length; 
     using (Stream os = req.GetRequestStream()) 
     { 
      os.Write(bytes, 0, bytes.Length); 
     } 
     WebResponse resp = req.GetResponse(); 
     cookieHeader = resp.Headers["Set-cookie"]; 
     Console.WriteLine(cookieHeader); 
     Console.WriteLine(); 
     //Get token 
     HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("https://www.facebook.com/dialog/oauth?client_id=282892925078054&redirect_uri=https://www.facebook.com/&response_type=token"); 
     webRequest.Headers.Add("Cookie", cookieHeader); 
     //webRequest.AllowAutoRedirect = false; 
     HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse(); 
     string redirectUrl = response.Headers.Get("Location"); 

     Console.WriteLine(redirectUrl);

但它沒有給我正確的URL。我究竟做錯了什麼？

編輯：我試着用AllowautoRedirect true/false。用false返回這個URL。 https://www.facebook.com/login.php?api_key=282892925078054&skip_api_login=1&display=page&cancel_url=https%3A%2F%2Fwww.facebook.com%2F%3Ferror_reason%3Duser_denied%26error%3Daccess_denied%26error_description%3DThe%2Buser%2Bdenied%2Byour%2Brequest.&fbconnect=1&next=https%3A%2F%2Fwww.facebook.com%2Fdialog%2Fpermissions.request%3F_path%3Dpermissions.request%26app_id%3D282892925078054%26client_id%3D282892925078054%26redirect_uri%3Dhttps%253A%252F%252Fwww.facebook.com%252F%26display%3Dpage%26response_type%3Dtoken%26fbconnect%3D1%26from_login%3D1&rcount=1

我希望這樣的事情：

https://www.facebook.com/#access_token=BAAEBSiRPCiYBAH0yF1cmZB14RBs9ZBvN7xQJaDvZAxd29WZCAZCpZAVzHXONNlUd9MOZAsTcSUimW7GITwrvN3px1XJSZBvK3wATdLzlQVOqQmlpBfs0ZCpsfydQV4ZCJEmpk4lmh9JCKbli78IDozYZBONxVszFZACQAgL2WPXF7680NGDQtD2IHl0oj6xbfqAtqpURSdJJmoZBXZAQZDZD&expires_in=5822

除非你想自己重寫這個庫，你可以使用Facebook C＃SDK，它是所有有關注冊的AppKey和應用標識。

看看：https://github.com/facebook-csharp-sdk/facebook-winclient-sdk

和示例：http://facebooksdk.net/docs/web/permissions/
