FILE:// URLs not working after upgrading to CEF76

[joeludwig]

I'm upgrading from 72 to 76, or trying to.

In 72 I could load the contents of a file URL like this:

Code: Select all

   CefRefPtr<CefRequest> request = CefRequest::Create();
   request->SetURL( "file:///c:/some/path/file.foo" );
   request->SetMethod( "GET" );

   CefRefPtr<CefURLRequest> myRequest = CefURLRequest::Create( request, myRequestClient, nullptr );


In 76 I get ERR_UNKNOWN_URL_SCHEME from that request. Is there something special I need to do to keep FILE URLs working in this new version of CEF?

File URLs are just paths on the local disk. Why not load them using system file functions such as fopen, etc, instead of using CefURLRequest?

I'm going through CefURLRequest because sometimes the URL will be a file and sometimes it'll use HTTP or HTTPS to fetch something remote. I didn't want to have two dramatically different code paths to handle those two cases.

I could obviously turn the URL into a path and just read the file. If CURLRequest isn't going to support FILE URLs going forward, that's exactly what I'll do. Is that the case?

It is unlikely that FILE URLs will be supported going forward.
