Laravel: Encode JSON responses in UTF-8
提问by JacopoStanchi
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:
我想将我的 API 的 JSON 响应编码为 UTF-8，但每次我做出响应时我都不想这样做：
return response()->json($res,200,['Content-type'=>'application/json;charset=utf-8'],JSON_UNESCAPED_UNICODE);
So I thought about making a middleware for all API routes which handle(...)function would be this:
所以我想为所有 API 路由制作一个中间件，它的handle(...)功能是这样的：
public function handle($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-typeheader of my responses is still application/jsonand not application/json; charset=utf-8; maybe because the json(...)function already sets a Content-typeheader and I cannot override it.
问题是它不起作用Content-type，我的回复的标题仍然application/json不是application/json; charset=utf-8；可能是因为该json(...)函数已经设置了一个Content-type标题，我无法覆盖它。
How should I do?
我应该怎么做？
Thank you for your help.

Its right there in the documentation, you want to use aftermiddleware (following code is from top of my head and it should work):
它就在文档中，您想在中间件之后使用（以下代码来自我的头脑，它应该可以工作）：
<?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($data, 200, ['Content-Type' => 'application/json;charset=UTF-8', 'Charset' => 'utf-8'],
JSON_UNESCAPED_UNICODE);
}
}
With above approach we can spot two anti-patterns:
通过上述方法，我们可以发现两种反模式：
- crafting response in middleware (you should do it in controller)
- using unescaped JSON response, Laravel creators made default the escaped one so why change it?!
- 在中间件中制作响应（您应该在控制器中进行）
- 使用未转义的 JSON 响应，Laravel 创建者将转义的默认设置为默认值，那么为什么要更改它呢？！
Removing middleware and using controller only
删除中间件并仅使用控制器
Put following code in app/Http/Controller.php
将以下代码放入app/Http/Controller.php
protected function jsonResponse($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);
在任何由基本控制器 (app/Http/Controller.php) 扩展的控制器中，您可以使用 $this->jsonResponse($data);
How pros do it
高手是怎么做的
They use eloquent resourcesor if there is more going on fractalis the way to go (in Laravel use spatie wrapper - https://github.com/spatie/laravel-fractal).
他们使用雄辩的资源，或者如果有更多的分形是要走的路（在 Laravel 中使用 spatie 包装器 - https://github.com/spatie/laravel-fractal）。
