Laravel: Encode JSON responses in UTF-8

问题

I want to encode the JSON responses of my API to UTF-8, but every time I make a response I don't want to do this:

return response()->json($res,200,['Content-type'=>'application/json;charset=utf-8'],JSON_UNESCAPED_UNICODE);

So I thought about making a middleware for all API routes which handle(...) function would be this:

public function handle($request, Closure $next) {
    $response = $next($request);
    $response->header('Content-type','application/json; charset=utf-8');
    return $next($request);
}

The problem is that it doesn't work, the Content-type header of my responses is still application/json and not application/json; charset=utf-8; maybe because the json(...) function already sets a Content-type header and I cannot override it.

How should I do?

Thank you for your help.

Its right there in the documentation, you want to use after middleware (following code is from top of my head and it should work):

<?php

namespace App\Http\Middleware;

use Closure;

class AfterMiddleware
{
    public function handle($request, Closure $next)
    {

        /** @var array $data */ // you need to return array from controller
        $data = $next($request);

        return response()->json($data, 200, ['Content-Type' => 'application/json;charset=UTF-8', 'Charset' => 'utf-8'],
        JSON_UNESCAPED_UNICODE);
    }
}

With above approach we can spot two anti-patterns:

crafting response in middleware (you should do it in controller)
using unescaped JSON response, Laravel creators made default the escaped one so why change it?!

Removing middleware and using controller only

Put following code in app/Http/Controller.php

protected function jsonResponse($data, $code = 200)
{
    return response()->json($data, $code,
        ['Content-Type' => 'application/json;charset=UTF-8', 'Charset' => 'utf-8'], JSON_UNESCAPED_UNICODE);
}

in any of the controllers that are extended by base controller (app/Http/Controller.php) you can use $this->jsonResponse($data);

How pros do it

They use eloquent resources or if there is more going on fractal is the way to go (in Laravel use spatie wrapper - https://github.com/spatie/laravel-fractal).
