使用Facebook C＃SDK發佈到頁面

Question

我一直在使用Facebook C＃SDK一段時間了，但有一個真正的舊版本，我仍然在使用REST API（我認爲）。我只關心使用API​​張貼到我自己的Facebook頁面（我有一個WCMS插件，將內容發佈到我們機構的Facebook頁面）。我想知道是否有人知道如何使用最新版本的SDK獲取此設置的好教程？我也關心offline_access何時會消失，所以我們也會讚賞這種想法。我寧願不必每隔60天手動獲取一個新的訪問令牌。這似乎有些不必要，因爲我用來發布帖子的應用與我試圖發佈的頁面位於同一個FB帳戶中。

我會建議你先閱讀這篇博客文章。 http://blog.prabir.me/post/Facebook-CSharp-SDK-Writing-your-First-Facebook-Application-v6.aspx

而這個文檔http://csharpsdk.org/docs/making-synchronous-requests

，找到圖形API後

我希望有一天prabir和Nathan將完成網站的文檔，我們將學習它clearly.for now.just挖掘網絡。

下面是做這件事：

public static string RefreshTokenAndPostToFacebook(string currentAccessToken) 
    { 
     string newAccessToken = RefreshAccessToken(currentAccessToken); 
     string pageAccessToken = GetPageAccessToken(newAccessToken); 
     PostToFacebook(pageAccessToken); 
     return newAccessToken; // replace current access token with this 
    } 

    public static string GetPageAccessToken(string userAccessToken) 
    { 
     FacebookClient fbClient = new FacebookClient(); 
     fbClient.AppId = "app id"; 
     fbClient.AppSecret = "app secret"; 
     fbClient.AccessToken = userAccessToken; 
     Dictionary<string, object> fbParams = new Dictionary<string, object>(); 
     JsonObject publishedResponse = fbClient.Get("/me/accounts", fbParams) as JsonObject; 
     JArray data = JArray.Parse(publishedResponse["data"].ToString()); 

     foreach (var account in data) 
     { 
      if (account["name"].ToString().ToLower().Equals("your page name")) 
      { 
       return account["access_token"].ToString(); 
      } 
     } 

     return String.Empty; 
    } 

    public static string RefreshAccessToken(string currentAccessToken) 
    { 
     FacebookClient fbClient = new FacebookClient(); 
     Dictionary<string, object> fbParams = new Dictionary<string, object>(); 
     fbParams["client_id"] = "app id"; 
     fbParams["grant_type"] = "fb_exchange_token"; 
     fbParams["client_secret"] = "app secret"; 
     fbParams["fb_exchange_token"] = currentAccessToken;    
     JsonObject publishedResponse = fbClient.Get("/oauth/access_token", fbParams) as JsonObject; 
     return publishedResponse["access_token"].ToString(); 
    } 

    public static void PostToFacebook(string pageAccessToken) 
    { 
     FacebookClient fbClient = new FacebookClient(pageAccessToken); 
     fbClient.AppId = "app id"; 
     fbClient.AppSecret = "app secret"; 
     Dictionary<string,object> fbParams = new Dictionary<string,object>(); 
     fbParams["message"] = "Test message";    
     var publishedResponse = fbClient.Post("/your_page_name/feed", fbParams); 
    }
