使用没有用户访问令牌的Facebook Graph API

Question

What I want to achieve

I want to display posts of a public facebook page on my website. For that reason it does not make sense to use a user access token, since it requires a login.

Possible Solution I found

I know you can use the App Tokens . There was a related question on Stackoverflow . I tested this using the Graph API Explorer.

https://graph.facebook.com/v2.3/google/statuses

returns: (#100) Requires user session

https://graph.facebook.com/v2.3/google/posts

returns: a valid result, but a totally different result than the same request with a User Access Token (less posts). same request for nike delivers a better result.

Questions

• Why does the same request deliver two diferent results?
• Can you only grab certain posts with the app token?
• Under which conditions can you get the full timeline without user access token?

Answer 1

It's all in the docs. There's a fundamental difference between posts and statuses , and the permission requirements are also well documented:

• https://developers.facebook.com/docs/graph-api/reference/v2.3/page/feed#readperms
• https://developers.facebook.com/docs/graph-api/reference/v2.3/status
*

Quotes:

• An access token is required to view publicly shared posts.
• A user access token is required to retrieve posts visible to that person.
• A page access token is required to retrieve any other posts.
