Description

I am trying to get a json only out for api routes in Laravel 11.

<?php

use App\Http\Middleware\ForceJsonResponse;
use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__ . '/../routes/web.php',
        api: __DIR__ . '/../routes/api.php',
        commands: __DIR__ . '/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->api(append: [
            ForceJsonResponse::class,
        ]);
    })
    ->withExceptions(function (Exceptions $exceptions) {

    })->create();

Just using append() works,

    ->withMiddleware(function (Middleware $middleware) {
        $middleware->append([
            ForceJsonResponse::class,
        ]);
    })

This is applicable for all routes, which i dont want.

I would like to know why the $middleware->api(append: []); is not working.

Steps To Reproduce

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class ForceJsonResponse
{
    public function handle(Request $request, Closure $next)
    {
        $request->headers->set('Accept', 'application/json');
        return $next($request);
    }
}

create this middleware,
now add it to bootstrap/app.php like shown above

Route::get('/user', function (Request $request) {
    return $request->wantsJson() ? 'true' : 'false';
});

The above code works fine.

The main thing is exceptions, want it for exceptions.

$middleware->api(append: [
            ForceJsonResponse::class,
        ]);

Any idea why this is not working ?

[VishnuSivadasVS]

 $middleware->append([
            ForceJsonResponse::class,
        ]);

this appends the header to all the requests - and it works perfectly fine, i just want to append it to api routes only.

$middleware->api(append: [
            ForceJsonResponse::class,
        ]);

Isn't this right?

[VishnuSivadasVS]

My mistake, should have use prepend instead of append in this case. That caused the issue.

$middleware->api(prepend:
            ForceJsonResponse::class,
        );

Thanks.
