發佈在Facebook頁面作爲頁面不作爲管理員用戶使用Facebook C＃SDK

Question

我正在開發C＃應用程序，它管理Facebook上使用Facebook C＃SDK的粉絲頁面。我遇到了兩個問題，一個是在牆上發佈消息，另一個是在粉絲頁上創建事件。

是否可以在粉絲頁面牆上作爲粉絲頁面發佈消息而不是管理員用戶？

我可以編程方式使用Facebook C＃SDK在粉絲頁面上創建事件（而不是作爲管理員，但作爲粉絲頁面）？

我經歷了其他一些SDK的其他教程，如Facebook PHP SDK。 PHP SDK允許將事件創建爲粉絲頁面，但對於C＃SDK，創建事件不會給出任何結果。

要發佈消息，您需要授予manages_pages權限，並使用「/ me/accounts」的結果從Fan頁面的帳戶獲取訪問令牌。

下面是我用張貼消息本身的粉絲專頁：

      var dicParams = new Dictionary<string, object>(); 
         dicParams["message"] = stSmContentTitle; 
         dicParams["caption"] = string.Empty; 
         dicParams["description"] = string.Empty; 
         dicParams["name"] = smContent.CmeUrl; 
         dicParams["req_perms"] = "publish_stream"; 
         dicParams["scope"] = "publish_stream"; 

         // Get the access token of the posting user if we need to 
         if (destinationID != this.FacebookAccount.UserAccountId) 
         { 
          dicParams["access_token"] = this.getPostingUserAuthToken(destinationID); 
         } 
         publishResponse = this.FacebookConnection.Post("/" + destinationID + "/feed", dicParams);

好吧，我只是碰到了這個同樣的事情。出於我的目的，我正在授權應用程序作爲粉絲頁面發佈到FB粉絲頁面。所以我可以讓多個用戶訪問該應用程序，但不能訪問粉絲頁面，以粉絲頁面的形式發佈。它符合我的要求。

無論如何，這裏是我如何使用C＃Facebook SDK Beta V5.0.9。 第一步，確保您試圖發佈的用戶帳戶能夠發佈到粉絲頁面，並有權從應用程序中這樣做。

其中大部分類似於VorTechS的帖子，只是稍微澄清一下。

Dictionary<string,string> fbParams = new Dictionary<string,string>(); 
       fbParams["message"] = Title; 
       fbParams["caption"] = string.Empty; 
       fbParams["description"] = string.Empty; 
       fbParams["req_perms"] = "publish_stream"; 
       fbParams["scope"] = "publish_stream"; 
       //Initialize Your Facebook Client in the manner that suits you, I did it by supplying a saved access token from a single users 
       FacebookWebClient fbClient = new FacebookWebClient(<YOUR_ACCOUNT_ACCESS_TOKEN>); 
       //Get the listing of accounts associated with the user 
       dynamic fbAccounts = fbClient.Get("/me/accounts"); 

       //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID) 
       foreach (dynamic account in fbAccounts.data) { 
        if (account.id == <DESTINATION_ID_OF_YOUR_FAN_PAGE>) { 
         //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out. 
         fbParams["access_token"] = account.access_token; 
         break; 
        } 
       } 
       //Then pass your destination ID and target along with FB Post info. You're Done. 
       dynamic publishedResponse = fbClient.Post("/" + <DESTINATION_ID_OF_YOUR_FAN_PAGE> + "/feed", fbParams);

我想感謝您的回覆，這真的很有幫助。對我而言，它仍然在我的Facebook頁面上發佈爲ME（而不是頁面）。我認爲這只是我得到令牌的方式。雖然，foreach循環不適合我。所以，我這樣做：

public void postFacebook(object sender, EventArgs e) 
{ 
    //You will get your "myAccessToken" at this adress: 
    //https://www.facebook.com/dialog/oauth?client_id=<YOUR_APP_ID>&redirect_uri=<THE_PAGE_YOU_WILL_RECEIVE_YOUR_TOKEN_AT>&scope=offline_access,manage_pages,publish_stream&response_type=token 
    string myAccessToken = "<IN_THE_RETURNED_URL_BELOW>"; 
    string myPageId = "<YOUR_FAN_PAGE_ID>"; 

    Dictionary<string,string> fbParams = new Dictionary<string,string>(); 
    fbParams["message"] = "Testing 1 2 test"; 
    fbParams["caption"] = string.Empty; 
    fbParams["description"] = string.Empty; 
    fbParams["req_perms"] = "publish_stream"; 
    fbParams["scope"] = "publish_stream"; 
    //Initialize Your Facebook Client in the manner that suits you, I did it by supplying a saved access token from a single users 
    Facebook.FacebookAPI fbClient = new Facebook.FacebookAPI(myAccessToken); 
    //Get the listing of accounts associated with the user 
    var fbAccounts = fbClient.Get("/me/accounts"); 

    //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID) 
    foreach (var account in fbAccounts.Dictionary["data"].Array) 
    { 
     if (account.Dictionary["id"].String == myPageId) 
     { 
      //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out. 
      fbParams["access_token"] = account.Dictionary["access_token"].String; 

      //Update the Access token (to post as the page). If you don't it will post as YOUR personal name. 
      fbClient.AccessToken = fbParams["access_token"]; 
      break; 
     } 
    } 



    //Then pass your destination ID and target along with FB Post info. You're Done. 
    dynamic publishedResponse = fbClient.Post("/" + myPageId + "/feed", fbParams); 
} 

順便問一下，你會需要這個SDK：SDK

在MVC4和C＃SDK

，這讓我的目標

[FacebookAuthorize("publish_stream")] 
    public ActionResult PostNotification(FacebookContext context) 
    { 
     var dicParams = new Dictionary<string, object>(); 
     dicParams["message"] = "đang tập code cho facebook ~@@"; 
     dicParams["caption"] = "bbbbb"; 
     dicParams["description"] = "cccccc"; 
     dicParams["name"] = "http://www.facebook.com"; 
     dicParams["req_perms"] = "publish_stream"; 
     dicParams["scope"] = "publish_stream"; 
     string destinationID = context.UserId; 
     context.Client.Post("/" + destinationID + "/feed", dicParams); 
     return RedirectToAction("Index"); 
    }
