How to identify a space given a pageID.

[John Corwith]

Due to the format of our page titles, our page URLs always resolve to ../pages/viewpage.action?pageId=########

And people are constantly receiving a URL to a page that results in the error: You don't have permission to view this page. 

This results in numerous tickets to our instance admin to determine the space/admins of the page.

It looks like I could possibly write a user macro to get ancestors (which also might not be viewable by the user) so what I really need is to identify the space or the page admins based on the pageId.

Are you looking for a way for your help desk to look up the space based on the page id or are you looking to show that to the user in the permissions message when it shows up?

All the options are interesting, I would like to get the name of the space to grant access to this page.

com.atlassian.confluence.pages.Page page = pageManager.getPage(pageId);
com.atlassian.confluence.spaces.Space space = page.getSpace();

getPage(long id) - Deprecated.
since 7.3.0, we can use ContentService.find(Expansion...) from plugins

com.atlassian.confluence.api.model.content.Content content = contentService.find(new Expansion("space")).withId(ContentId.of(pageId)).fetchOrNull();
com.atlassian.confluence.api.model.content.Space space = content.getSpace();
