Twig - Get URL for canonical tag

问题:

I'm looking to create a dynamic rel="canonical" tag in my application which pulls in the current URL but want to ensure any query parameters are removed. E.g http://www.example.com/test/?page=2 should have the canonical as http://www.example.com/test/, therefore {{ app.request.uri }} doesn't work as this pulls in ?page=2 as well.

Does anyone know how to pull in the absolute path of a page without the query parameters?

回答1:

This will work,

{{ url(app.request.attributes.get('_route'), app.request.attributes.get('_route_params')) }}

回答2:

I just tried to dump baseUrl and can confirm that it does not work.

However, this works:

{{ app.request.getSchemeAndHttpHost ~ app.request.baseUrl ~ app.request.pathInfo }}

I know, it's not pretty but it does the job :)
