如何使用ruby fb_graph發佈Facebook頁面更新？

Question

我只是想將帖子自動發送到Facebook的某些事件到我的公司Facebook頁面。從我目前閱讀的內容看來，它應該是直截了當的，但是我正遇到障礙。

的一些代碼，我已經和誤差如下一個例子：

user = FbGraph::User.me(access_token) 
    user = FbGraph::User.fetch('PageName') 
    FbGraph.debug! # yields true 
    user.feed!(
    :message => 'Updating via FbGraph', 
    :link => 'https://domain.tld', 
    :name => 'PageName', 
    :description => 'This is a test post to be deleted' 
) 

這將返回以下錯誤：

在developers.Facebook.com/apps - >設置 - >驗證對話框我將Extended Permissions設置爲包括publish_stream和status_update。

我發現curl與同樣獲得確實的工作方式如下：

curl -F 'access_token=MY_BIG_OLE_LONG_TOKEN' -F 'message=testing message' https://graph.facebook.com/MyPage/feed 

我缺少權限的設定某處或不與fb_graph紅寶石寶石正確調用API？

Answer 1

您需要查看圖API的page的文檔。檢查字段access_token其中manages_pages。您需要在extended_permission中設置此選項。這裏的關鍵是獲得正確的標記。文本字段中的令牌可能無法在大多數情況下運行。您需要發送GET請求到https://graph.facebook.com/YOUR_PROFILE_ID/accounts以獲取正確的令牌。似乎你已經得到了正確的。

我以前用過koala gem。如發佈here。

page_graph = Koala::Facebook::GraphAPI.new(@access_token)
page_graph.put_object('MyPage', 'feed', :message => 'This is posted as the page')

嗯，我必須說，Facebook的API文檔缺乏開發人員友好。你需要深入挖掘才能獲得最簡單的工作。

我希望這會幫助您開始自動化FB帖子。
