php - Laravel:如果运行某个中间件，则向模型添加全局范围

Question

是否可以根据是否应用中间件来启用全局范围？

我有一个全局范围，我想为我网站的某个部分启用并禁用其余部分(客户与管理区域)，我在想您是否可以通过检查中间件“EnableGlobalScopeMiddleware”是否已运行来做到这一点?

Answer 1

是的，创建中间件 EnableGlobalScopeMiddleware

php artisan make:middleware EnableGlobalScopeMiddleware

并将全局范围应用于 handle 中的模型功能

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Database\Eloquent\Model;

class EnableGlobalScopeMiddleware
{
    public function handle($request, Closure $next)
    {
        Model::addGlobalScope('foo', function (Builder $builder) {
            $builder->where('foo', 'bar');
        });

        return $next($request);
    }
}

在 App\Http\Kernel注册中间件通过将其添加到 protected $routeMiddleware数组属性

protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
    'can' => \Illuminate\Auth\Middleware\Authorize::class,
    'global' => \App\Http\Middleware\EnableGlobalScopeMiddleware::class, // <-- Here
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
];

并将其应用于特定的路由，例如 /admin前缀路由组

Route::middleware(['global'])->prefix('admin')->group(function () {
    // Routes here
});
