应用访问令牌是最基本的，不允许您发布任何内容。为了向Facebook页面（作为页面）发布某些内容，您需要获取页面访问令牌。

The App Access Token is the most basic one, and will not allow you to post anything. In order to post something to a Facebook Page (as a Page), you need to get a Page Access Token.

该过程有点复杂，因为您实际需要要授权用户首先使用manage_pages权限，使用用户访问令牌，您可以调用API获取页面访问令牌（/ me / accounts）。

The process is a bit complicated, because you actually need to authorize the user with the "manage_pages" permission first, with the User Access Token you can call the API to get a Page Access Token (/me/accounts).

您还可以尝试客户端令牌（开发人员设置>高级），我从来没有工作与那个，但它可能是最简单的解决方案。无论如何，App Access Token是错误的。

You can also try the "Client Token" (Developer Settings > Advanced), i never worked with that one but it could be the easiest solution. In any case, an App Access Token is the wrong one.
