php - 本地化 Laravel

Question

我一直在尝试更新网站的语言。

Controller

public function getUpdateLanguage(Request $request) {
        $request_data = $request->all();
         \Session::put('locale', $request_data['language']);
        return redirect()->back();
}

中间件:

 public function handle($request, Closure $next)
 { 
    if ( \Session::has('locale')) {
        \App::setLocale(\Session::get('locale'));
    }
    return $next($request);
 }

但是 if (\Session::has('locale')) 的 true block 永远不会执行，并且语言始终为 'en' 并且永远不会更新。如果我尝试的话效果很好

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

     \App::setLocale('arabic');

    return $next($request);
 }

内核:

protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\TrustProxies::class,
        \App\Http\Middleware\Localization::class,
    ];

本地化是我的中间件。语言更新 Controller 方法重定向到主页:

public function getIndex() {
        return view('frontend.home');
}

有人可以指导我 session 值在哪里被清除或者我是否做错了并且有更好的方法？

将 \Illuminate\Session\Middleware\StartSession::class 添加到 kernel.php 中的 middleware 数组:

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \App\Http\Middleware\TrustProxies::class,
    \App\Http\Middleware\Localization::class,
];
