Question

我只想将Facebook上的某些活动自动发布到我公司的Facebook页面。从我到目前为止看来，它似乎应该是直截了当的，但是我遇到了障碍。

我的一些代码示例，错误如下：

  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'  
  )

这会返回以下错误：

======= [FbGraph] API REQUEST STARTED =======

在 developers.Facebook.com/apps - ＆gt;上设置 - ＆gt;验证对话我将Extended Permissions设置为包含publish_stream和status_update。

我发现使用相同令牌的curl访问确实如下工作：

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

我是否错过了某个地方的权限设置或者没有使用fb_graph ruby gem正确调用api？

Answer 1

您需要查看图表API page的文档。查看access_token字段manages_pages。您需要在extended_permission中设置此选项。这里的关键是获得正确的令牌。文本字段中的标记可能在大多数时间不起作用。您需要向https://graph.facebook.com/YOUR_PROFILE_ID/accounts发送GET请求以获取正确的令牌。好像你已经得到了正确的那个。

之前我使用过koala gem。已发布here。

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

我必须说facebook的API文档缺乏开发人员的友好性。你需要深入挖掘才能获得最简单的工作。

我希望这可以帮助您开始自动化FB帖子。
