我需要获得价值22.2.2014.但这不起作用,我该怎么办?提前致谢.
根据此Facebook页面选项卡文档,您可以通过调用http帖子来更新选项卡的"位置",如下所示:
https://graph.facebook.com/v2.5/{pageId}/tabs?access_token={pageToken}
Run Code Online (Sandbox Code Playgroud)
在此端点,您可以使用POST请求更新页面选项卡的位置,并传递参数tab = TAB_NAME&position = TAB_POS.
这最近已停止工作(也许是因为Facebook推出了Admins的页面模板).
我能够更新选项卡的custom_name和图像.我还可以看到选项卡的"position"属性已更改为新值.但是,页面上Tab的实际位置不会改变.之前调用上述帖子,实际上会移动其他选项卡列表中的选项卡.
我正在寻找帮助改变标签位置的新方法.
谢谢.
