EPiServer - How can I get current page data?

Question

I am working on EPiServer. I am creating a plugin to edit content of current page. I am trying to get the data from the code following:

 var pageRouteHelper = EPiServer.ServiceLocation.ServiceLocator.Current.GetInstance<IPageRouteHelper>();

 var currentPage = pageRouteHelper.Page;

but every time the currentPage returns me the content of the start page. What is missing here and I cannot get the page I have open on screen content?

Answer 1

If we have the page id, for instance 139, with the following code we can retrieve the page's content.

var pageId = 139;

var pageRef = new PageReference(pageId);

var contentRepository = ServiceLocator.Current.GetInstance<IContentLoader>();

var page = contentRepository.Get<PageData>(pageRef);

A simply, but may not the most practical way, to get the page id from the browser is

var pageUrl = HttpContext.Current.Request.RawUrl;

From the pageUrl we can retrieve the pageId.
