更改选择菜单上网站的语言不起作用-MethodNotAllowedHttpException

Question

我安装了此软件包“ https://github.com/mcamara/laravel-localization”。

我想基于选择菜单来翻译站点，因此，当用户在选择菜单中选择一种语言时，应该使用上述软件包将站点内容翻译为所选语言。

但是它不起作用，当用户以以下形式更改语言时，下面的代码在RouteCollection.php中显示为“ Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException。

然后我上了这个课：

namespace App\Http\Middleware;

use Closure;

class Translate
{
    protected $default = 'en';

    protected $languages = [
         'en',
         'nl',
         'fr',
    ];

    public function handle($request, Closure $next)
    {
        if($request->has('language')) {
            $lang = $request->language;
            if(array_search($lang, $this->languages) === false) {
                $lang = $this->default;
            }

            $request->session()->put('lang', $lang);
        }

        \LaravelLocalization::setLocale( $request->session()->get('lang') );

        return $next($request);
    }

}

在kernel.php中：

  protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,  // <-- without this one, it wont work
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
            \App\Http\Middleware\Translate::class,   // <-- Add it here
        ],
        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

然后用户的选择菜单更改语言：

form method="get" id="translate">
  <select name="language" class="form-control font-weight-normal text-gray" id="language" onchange="localize">
    <option value="en">English</option>
    <option value="fr">French</option>
    <option value="es">Spanish</option>
    <option>5</option>
  </select>
</form>

jQuery：

$(document).ready(function(){

 var myFormName = "translate";
 $('#language').on('change', function)(){

     $('#translate).submit();
  });
});
