The assetserver.Options.Handler does not work in dev mode

[eryx]

Description

type custemHttpHandler struct {}

func (h *custemHttpHandler) ServeHTTP(wr http.ResponseWriter, req *http.Request) {
  log.Printf("handler serve %s", req.URL.Path)
}

err := wails.Run(&options.App{
  AssetServer: &assetserver.Options{
    Assets:  assets,
    Handler: &custemHttpHandler{},
  },
})

To Reproduce

wails dev

log output:

DEB | [AssetHandler] File 'file/id/e6d95e4' not found, serving '/file/id/e6d95e4' by AssetHandler
DEB | [ExternalAssetHandler] Loading 'http://localhost:5173/file/id/e6d95e4'

Expected behaviour

use wails build and exec "./build/bin/myproject.app/Contents/MacOS/myproject" working fine.

log output:

DEB | [AssetHandler] File 'file/id/e6d95e4' not found, serving '/file/id/e6d95e4' by AssetHandler
handler serve file/id/e6d95e4

Trying to load Go assets from the Vite port in this way isn't going to work. Try opening http://localhost:34115

1. Thank you for your response, but using the localhost: 34115 method still doesn't work.
2. In the new situation, adding a file extension, such as changing /file/id/e6d95e4 to /file/id/e6d95e4.json, made it work.
