如何在v5中使用CanvasAuthorizer.GetLoginUrl？

Question

我正在嘗試將我的ASP.NET WebForms IFrame Canvas應用程序從Facbook C＃SDK 4.02升級到5.03測試版。大部分變化都非常簡單。但是，我不是100％確定CanvasAuthorizer.GetLoginUrl（）。

這是我爲V4.02

CanvasAuthorizer _authorizer = new CanvasAuthorizer {Perms = "publish_stream,offline_access"}; 

Uri authurl = _authorizer.GetLoginUrl(new HttpRequestWrapper(Request)); 
CanvasRedirect(authurl.ToString()); 

而且這裏的代碼是基於爲V5.03我最好的猜測對PHP的例子在http://developers.facebook.com/docs/reference/dialogs/oauth

CanvasAuthorizer _authorizer = new CanvasAuthorizer {Perms = "publish_stream,offline_access"}; 

Dictionary<string, object> parameters = 
    new Dictionary<string, object> 
     { 
      {"scope", _authorizer.Perms}, 
      {"client_id", _authorizer.AppId}, 
      {"redirect_uri", _authorizer.ReturnUrlPath}, 
      {"response_type", "token"} 
     }; 
Uri authurl = _authorizer.GetLoginUrl(parameters); 
CanvasRedirect(authurl); 

將這項工作

？有一個更好的方法嗎？

一些試驗和錯誤後，我用它來工作如下：

CanvasAuthorizer _authorizer = new CanvasAuthorizer {Perms = "publish_stream,offline_access"}; 
if (!_authorizer.IsAuthorized()) 
{ 
    _authorizer.HandleUnauthorizedRequest(); 
}
