问题
For example, let's say I need to "crawl" (not manually since it looks against Facebook's policies but via graph API) some information from a Facebook's brand page (e.g. https://www.facebook.com/nike/ ).
For example I may need to collect the following fields from a set of brand pages (not just one, such as the one mentioned above, for which I could definitely do it manually), when they are publicly available: ("About tab") - description - address - website - ...
I was reading Facebook's graph API docs and permissions.
However these permissions are related to users and I already worked with that. What I learned it that it works by
Facebook login --> auth the app to use my data --> the app has access to my data as a Facebook user.
However I'm now interested in brand pages for which I found this docs and this (access token). However it seems that to be able to use this access token I need to be a user with some role in the page (e.g. admin) and not any user who just liked that page.
So, is it possible to access brand pages' data (read-only, i.e. GET) via graph API without actually owning/admin/publishing on that page?
回答1:
Apparently no "special" access token is required to access pages' public info.
For example I can create any page (not app) in my Facebook account and then use
GET https://graph.facebook.com/(*1)/feed?access_token=(*2)
- (*1) the page's name (nike) or ID
- (*2)my "bridge" page (i.e. empty page, only used to have an access token. not the page I'm using the graph api on)'s access token
Similarly for /posts/ etc.
