Laravel 路由组全局范围

Question

我在解决如何将全局范围添加到 laravel 中的路由组时遇到了一些麻烦。我所做的是

Route::group([
    "prefix" => "customer",
    "namespace" => "Customer",
    "as" => "Customer.",
], function() {
    //make sure only public salons are displayed!
    \App\Salon::addGlobalScope("public", function(\Illuminate\Database\Eloquent\Builder $builder) {
        $builder->where("public", 1);
    });

    Route::get("/", "IndexController@index")->name("index");

    Route::get("/salon/{salon}", "SalonController@show")->name("salon.show");

});

这个想法是我希望在整个组中添加公共查询！这包括在沙龙模型和路由绑定上调用 newQuery。这可能吗？假设我很懒惰，而不是定义路由绑定并将范围添加到每次使用中，我宁愿在这里执行此操作，因为我在整个组中都需要此绑定！

提前致谢 ：）

创建一个中间件来添加路由的范围：

在app/Http/Kernel.php：

protected $routeMiddleware = [
    // Other route middleware
    'restrict.public' => App\Http\Middleware\AddPublicScope::class
];

在您创建的app/Http/Middleware/AddPublicScope.php：

namespace App\Http\Middleware;

use Closure;
use App\Salon;
use Illuminate\Database\Eloquent\Builder;

class AddPublicScope
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        Salon::addGlobalScope('public', function($builder) {
            $builder->where('public', 1);
        });

        return $next($request);
    }
}

然后在您的路由组定义中：

Route::group([
    "prefix" => "customer",
    "namespace" => "Customer",
    "middleware" => ['restrict.public']
    "as" => "Customer.",
], function() {

    Route::get("/", "IndexController@index")->name("index");

    Route::get("/salon/{salon}", "SalonController@show")->name("salon.show");

});
