Laravel 路由语言环境中间件无法与模型绑定一起使用

Question

我使用这个指南：https://mydnic.be/post/how-to-build-an-efficient-and-seo-friendly-multilingual-architecture-in-laravel-v2

我有这些路由和中间件：

$locale = request()->segment(1);

Route::middleware('localized')->prefix($locale)->group(function() {
     Route::get('/contacts', 'ContactController@index');
     Route::get('/page/{page}', 'PageController@index');
});

以及从 Kernel.php 本地化的中间件 -> routeMiddleware:

public function handle(Request $request, Closure $next)
{
    if (!array_key_exists($request->segment(1), config('translatable.locales'))) {
        $segments = $request->segments();

        $segments = Arr::prepend($segments, config('app.fallback_locale'));

        if($request->session()->has('language')) {
            $segments[0] = session('language');
        }

        return redirect()->to(implode('/', $segments));
    }
    
    return $next($request);
}

当我访问：site.test/contacts 时，他将我重定向到语言环境：site.com/en/contacts 当我访问 site.test/page/test 时，找不到 404，如果我访问：site.com/en/page/test 然后页面工作。带有路由模型绑定的语言环境重定向问题。

在控制器页面中我有：

public function index(Page $page) 
{
    return view('page', compact('page'));
}

在可翻译的.php中：

'locales' => [
    'de' => 'Deutsch',
    'en' => 'English',
],

在 AppServiceProvider 中：

public function boot()
{
    if(array_key_exists(request()->segment(1), config('translatable.locales'))) {
        app()->setLocale(request()->segment(1));
    }
}

我能够解决这个问题，但这使我们无法访问会话，您检查了会话是否具有“语言”，如果是，那么前置语言环境值应设置为会话中的语言值。以下是我所做的；

在路由文件中

$locale = request()->segment(1);

Route::prefix($locale)->group(function() {
     Route::get('/contacts', function(){
         echo "hello contact";
     });
     Route::get('/page/{page}', function(Request $request, $page){
        return "hello Page {$page}";
     });
});

在 MiddleWare 文件中我做了

public function handle(Request $request, Closure $next)
{
    if (!array_key_exists($request->segment(1), config('translatable.locales'))) {
    $segments = $request->segments();

    $segments = Arr::prepend($segments, config('app.fallback_locale'));
    
    // Remove the session check as we don't have access to session yet
    /*if($request->session()->has('language')) {
        $segments[0] = session('language');
    }*/

    return redirect()->to(implode('/', $segments));
}

    return $next($request);
}

现在在中间件的 Kennel.php 文件中，在 $middleware 数组中添加您的中间件类

/**
 * The application's global HTTP middleware stack.
 *
 * These middleware are run during every request to your application.
 *
 * @var array
 */
protected $middleware = [
    ...
    \App\Http\Middleware\Localized::class, //This is the Localized Middlewere class
];

然后尝试访问 site.test/page/1000 ...它将被重定向到 site.test/{app.fallback_locale}/page/1000。在我的情况下 site.test/en/page/1000

更新

在阅读了这个issue on git for laravel 之后，我想到了在本地化中产阶级之前添加会话并且它起作用了。我不确定这是否是一种好的做法，但它完成了工作。

在 MiddleWare 文件中我做了

public function handle(Request $request, Closure $next)
{
    if (!array_key_exists($request->segment(1), config('translatable.locales'))) {
    $segments = $request->segments();

    $segments = Arr::prepend($segments, config('app.fallback_locale'));
    
    // We can have session back on
    if($request->session()->has('language')) {
        $segments[0] = session('language');
    }

    return redirect()->to(implode('/', $segments));
}

    return $next($request);
}

现在在中间件的 Kennel.php 文件中，在本地化中间件类之前添加 Session 中间件

/**
 * The application's global HTTP middleware stack.
 *
 * These middleware are run during every request to your application.
 *
 * @var array
 */
protected $middleware = [
    ...
    \Illuminate\Session\Middleware\StartSession::class,
    \App\Http\Middleware\Localized::class, //This is the Localized Middlewere class
];
