Add URL templates match by extension

[BbIKTOP]

Since regex is not working, is it possible at least to add url match by extension? Like this:

diff WebHandlerImpl.h WebHandlerImpl.h.orig
108,115d107
<       if (_uri.length() && _uri.startsWith("/*.")) {
<         String uriTemplate = String (_uri);
<         uriTemplate = uriTemplate.substring(uriTemplate.lastIndexOf("."));
<         if (!request->url().endsWith(uriTemplate))
<           return false;
<       }
<       else

You could create your own handler and register it.

@BlueAndi Sorry, don’t understand, could you explain please? How to create handler for some particular file type/extension? I tried regular expressions first, even considered they’re very heavy and consume a lot of precious resources on esp8266, but didn’t succeed since there’s a bug in the current gcc. How can i make different handlers now?
Thank you

You can add a handler via

ESPAsyncWebServer/src/ESPAsyncWebServer.h

Line 420 in f13685e

AsyncWebHandler& addHandler(AsyncWebHandler* handler);

Inherit your handler from AsyncWebHandler, like its done for the AsyncStaticWebHandler.
This way you could create it, as you shown in your initial post.

A different way would be to register a callback for "/xxx/yyy/*" via

ESPAsyncWebServer/src/ESPAsyncWebServer.h

Line 423 in f13685e

AsyncCallbackWebHandler& on(const char* uri, ArRequestHandlerFunction onRequest);

In the callback you get access to the requested uri by request->url() and you can post-process it there.

The better option depends on how many different uri you will have.

@BlueAndi but i need different handlers for different file types (i.e. file extensions)
Current url parameter does not support this, isn’t it?

[BlueAndi]

Yes and no. If your handler (option 1 above) is generic enough on the interface, you implement it once, but instantiate it several times with different file extensions as parameter.

Yes, current url parameter doesn't support this.

@BlueAndi so, why not simplify this and just add a few lines of code from my pr #751? It will provide a simple intuitive way to implement such a functionality

[BlueAndi]

Not my decision, you have to wait for the maintainer. ;-)

@BlueAndi Sure, but looks like nobody here for months...
