Laravel 5.4会话应用程序SetLocale不起作用

Question

在我的应用程序中，我正在尝试在这样的应用程序中更新Locale：in Locale Middleware文件：

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

但是，它不起作用

i注册kernel.php已经

protected $middleware = [
    IlluminateFoundationHttpMiddlewareCheckForMaintenanceMode::class,
    IlluminateFoundationHttpMiddlewareValidatePostSize::class,
    AppHttpMiddlewareTrimStrings::class,
    IlluminateFoundationHttpMiddlewareConvertEmptyStringsToNull::class,
    AppHttpMiddlewareLanguageChange::class,
];

我创建路由Web

Route::get('lang/{locale}', function ($locale) {
//App::setLocale($locale);
Session::put('locale', $locale); 
return Redirect::back(); 

}）;

我的刀片

<li class="dropdown">
          <a class=" dropdown-toggle" id="dropdownLang"
                           data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
                            @if(IlluminateSupportFacadesSession::get('locale') == "th")
                                THAI
                            @elseif(IlluminateSupportFacadesSession::get('locale') == "en")
                                English
                            @endif
                            <span class="caret"></span></a>
                        <ul class="dropdown-menu" aria-labelledby="dropdownLang">
                            <li>
                                <a href="{{url('lang/en')}}">
                                    ภาษาอังกฤษ (English)
                                </a>
                            </li>
                            <li>
                                <a href="{{url('lang/th')}}">
                                    ภาษาไทย (Thai)
                                </a>
                            </li>
                        </ul>
                    </li>

我认为您应该在'startessesses'中间件之后包括中间件。

protected $middlewareGroups = [
    ...
    'web' => [
        ...
        IlluminateSessionMiddlewareStartSession::class,
        AppHttpMiddlewareLocale::class,
        ...
    ],
    ...
];
