Laravel 5多国语言不起作用 [英] Laravel 5 multi language not working

问题描述

我试图本地化我的应用程序，但似乎缺少了一些东西.我以前对此没有任何了解，因此很难入门.这是我的routes.php

I tried to localization my app, but seems like I'm missing something. I don't have any previous knowledge about this and therefore it's pretty hard to get started. Here is my routes.php

Route::get('/lang/{lang}', 'LangController@index');

这是我的LangController.php

And here is my LangController.php

 public function index($lang)

{
    $langs =['en', 'de'];
    if(in_array($lang, $langs)){
        Session:set('lang', $lang);
        return Redirect::back();
    }
}

我在中间件中设置:(Lang.php)

I set in middleware:(Lang.php)

 public function handle($request, Closure $next)

{

    if($lang = Session::get('lang')){
        \Lang::setLocale($lang);
    }

    return $next($request);
}

在Http \ Kernel.php中启用它:

Enable it in Http\Kernel.php:

  protected $middleware = [

   \App\Http\Middleware\Lang::class,
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \App\Http\Middleware\EncryptCookies::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \App\Http\Middleware\VerifyCsrfToken::class,

    ];

在我的blade.php中

In my blade.php

 {{ Lang::get('home.hello')}}
   CURRENT: {{ Lang::getLocale() }} <br /> <br />
 <a href="{{ url('lang/de') }}">Germany</a> | <a href="{{ url('lang/en') }}">English</a>

请帮助.我看不到我想念的东西... 在字段CURRENT中，按德国时应为"de"，按英语时应为"en"，但按德国时仍为"en" ...(默认为"en" config/app.php->"locale" '=>'en'，)

Please help.I do not see what I missing... In field CURRENT when press Germany it shoul be 'de' and when press English it shoul be 'en' but when press Germany it still stay 'en'... (default is 'en' config/app.php -> 'locale' => 'en',)

推荐答案

由于您正在中间件中使用会话，因此，所需的值将在StartSession中间件设置会话之前不可用.

Because you are using the session in your middleware, the values you need will not be available until the StartSession middleware sets up the session.

因此，您应该在此之后将中间件添加到某处，就像这样:

So you should add your middleware somewhere after that, like so:

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \App\Http\Middleware\EncryptCookies::class,
    \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
    \Illuminate\Session\Middleware\StartSession::class, // Init session
    \App\Http\Middleware\Lang::class, // Set locale
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    \App\Http\Middleware\VerifyCsrfToken::class,
];

除此之外，您的控制器代码中还存在一个小的语法错误.在将值分配给index控制器方法中的会话时，您忘记为范围解析运算符添加第二个冒号(:).因此:

Aside from that you also have a small syntax error in your controller code. You forgot to add the second colon (:) for the scope resolution operator, when assigning the value to the session in your index controller method. So this:

Session:set('lang', $lang);

应该是这样

Session::set('lang', $lang);
