会话不在laravel中持续存在

Question

我在laravel中使用Session，但是当我在控制器中获得Session时，它不起作用。

web.php

Route::get('locale/{locale}',function ($locale){
    //Session::put('locale',$locale);
    session(['locale' => $locale]);
    Session::save();
    return redirect()->back();
});

Localization.php

public function handle($request, Closure $next)
{
    if(\Session::has('locale')){
        \App::setLocale(\Session::get('locale'));
        session(['locale' => \Session::get('locale')]);
        \Session::save();
    }

    return $next($request);
}

Kernel.php

protected $middleware = [
    \App\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,
];

/**
 * The application's route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
    'web' => [
        \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,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
        \App\Http\Middleware\Localization::class,
    ],

    'api' => [
        \App\Http\Middleware\EventLogMiddle::class,
        'throttle:600,1',
        'bindings',
    ],
];

MachCtrl.php（扩展控制器）

public function index()
{
    $lang = session('locale');
    $config = json_encode([
        "table" => "Machine_list",
        "title" => "machine list",
        "rows" => 20,
        "column" => [
            "Machine_id", "VM_name", "Machine_location","IP_address", 
            "Network_status", "Current_status"
        ],
        "CUDP" => "0111",
        "CreateRoute" => route('machine.create'),
        "DeleteRoute" => route('machine.destroy'),
        "UpdateRoute" => route('machine.editInfo'),
        "locale" => $lang,
    ]);

    return view('table.show')->with(['config' => $config, 'lang' => 
                                                            $lang]);
}

我将Session保存在路由器和中间件中，这是行不通的。

但是当我将Session放入Controller时，它就可以工作了。如下代码：

public function index()
{
    session(['locale' => 'en']);
    $lang = session('locale');
    $config = json_encode([
        "table" => "Machine_list",
        "title" => "machine list",
        "rows" => 20,
        "column" => [
            "Machine_id", "VM_name", "Machine_location","IP_address", 
            "Network_status", "Current_status"
        ],
        "CUDP" => "0111",
        "CreateRoute" => route('machine.create'),
        "DeleteRoute" => route('machine.destroy'),
        "UpdateRoute" => route('machine.editInfo'),
        "locale" => $lang,
    ]);

    return view('table.show')->with(['config' => $config, 'lang' => 
                                                           $lang]);
}

我真的很想知道我的项目中发生了什么。 谢谢。

编辑： 我在代码中使用dd（session（））：

-web.php

Route::get('locale/{locale}',function ($locale){
    Session::put('locale',$locale);
    Session::save();
    dd(session());
    return redirect()->back();
});

结果：

-Localization.php

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


    if(\Session::has('locale')){
        \App::setLocale(\Session::get('locale'));
        session(['locale' => \Session::get('locale')]);
        //dd(session());
        \Session::save();

    }

    return $next($request);
}

结果：

-MachCtrl.php

public function index()
{
    dd(session());
    $lang = session('locale');
    $config = json_encode([
        "table" => "Machine_list",
        "title" => "machine list",
        "rows" => 20,
        "column" => [
            "Machine_id", "VM_name", "Machine_location","IP_address", 
            "Network_status", "Current_status"
        ],
        "CUDP" => "0111",
        "CreateRoute" => route('machine.create'),
        "DeleteRoute" => route('machine.destroy'),
        "UpdateRoute" => route('machine.editInfo'),
        "locale" => $lang,
    ]);

    return view('table.show')->with(['config' => $config, 'lang' => 
                                                            $lang]);
}

结果：

尝试使用其他会话驱动程序来解决问题。

Answer 2

我检查了我的工作代码。我将整个周期设置为：

语言中间件：

class Language
{
    protected $app;

    public function __construct(Application $app, Request $request) {
        $this->app = $app;
    }

    public function handle($request, Closure $next)
    {
        $this->app->setLocale(session('user_locale', config('app.locale')));

        return $next($request); 
    }
}

在我的中间件Kernel.php中：

protected $middlewareGroups = [
    'web' => [
         \Illuminate\Session\Middleware\StartSession::class,
         //...
         \App\Http\Middleware\Language::class,
    ]
];

并在途中：

Route::get('locale/{locale}',function ($locale){
     session(['user_locale' => $locale]);
});
