CEF3: Add response filtering support #515

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Add response filtering support. See 
http://magpcss.org/ceforum/viewtopic.php?f=10&t=645 for CEF3 information.

It would be helpful to support changing of the MIME type sent to the browser. 
Maybe  response->SetMimeType().
Use case: response contains special data identified by special MIME type, for 
example "application/special1". I need to convert special data to HTML and 
display it transparently in the browser. It requires possibility to change 
response MIME type to "text/html", data conversion could be done using 
CefContentFilter.

@comment#1: if i'm rightly remember, response filtering it is something about 
response rewriting thing (data). but i'm agree, that it is very cool to have 
handle to rewrite even headers.

I.e. it will be cool to allow rewrite whole headers on response, and provide 
filter for data stream.

This is just for clarification. Thanks!

Response headers can be viewed/changed via 
CefNetworkDelegate::OnHeadersReceived(). I'm not sure if there's a great way to 
filter response content -- it may be necessary to subclass URLRequestJob and 
return via CefRequestInterceptor::MaybeInterceptResponse().

Is this feature being investigated now? I badly need this in my project. If no 
one is working on this yet, I'd like to try provide my patch since I'm not busy 
recently. Though I haven't read CEF3's code in depth, I think this may be not 
quite complicate a task.

There is a way around to accomplish this functionality using the existing api 
(GetResourceHandler and URLRequest/URLRequestClient), Marshall has explained 
it on the CEF Forum:

    There's no great way to filter response contents with CEF3 currently. 
    You can use CefResourceHandler via CefRequestHandler::GetResourceHandler 
    and execute the request/return the response contents yourself using 
    CefURLRequest.

Does the fix in issue 1098 make this any easier? At a glance, they seem 
related...
