Get a Facebook Page's public posts without an auth token

问题

Is it possible (using the facebook graph API) to get the last 5 posts made by a Facebook Page?

I would like to display this information in an Android app and want to avoid the overhead of using the Facebook Android SDK to avoid showing the "[App] would like to access your public profile and friend list" message because it's annoying and inaccurate.

The following call works without an auth token for example: https://graph.facebook.com/nike

But this one doesn't: https://graph.facebook.com/nike/posts

{
   "error": {
      "message": "An access token is required to request this resource.",
      "type": "OAuthException",
      "code": 104
   }
}

I could scrape the HTML off of this page without an auth token but this seems like overkill for such a simple task: https://www.facebook.com/nike/posts

To summarize:

1. Is this really a limitation of the API?

2. Is there a way to suppress the "[App] would like to access your public profile and friend list" message when acquiring an auth-token with no extra permissions using the Android SDK?

3. Is it perhaps possible using a server-side SDK?

EDIT: Looks like the best way to do this is server-side with a long-lived App Access token.

No.

Yes. If you read the documentation properly (Post), its clearly mentioned that any valid access token is required to fetch the details* of the posts of a page. So, you could use the App access token, which you could get without any authorization step- from here or a simple GET request (server-side)-

GET /oauth/access_token?
client_id={app-id}
&client_secret={app-secret}
&grant_type=client_credentials

Is it perhaps possible using a server-side SDK?

Depends on you, how you want to implement.

*Note: Of course, the posts that you can see would be the public posts only (that could be seen even if a user is logged-out); else you might require user authentication with read_stream permission.
