里，中间件可以接受额外的自定义参数，例如，如果你的应用需要在执行给定 的 action 之前验证被授予指定“角色”的认证用户，可以创建一个 RoleMiddleware 来接收角 色名称作为额外参数： namespace App\Http\Middleware; use Closure; class RoleMiddleware { /** * 运行请求过滤器. vendor 包发布语言文件的默认目录做了移动，所有 vendor 包语言文件从 resources/lang/packages/{locale}/{namespace}移动到了 resources/lang/vendor/{namespace}/{locale}目录。例如，Acme/Anvil 包的 acme/anvil::foo 英语语言文件将会从 resources/lang/pack 另一个通用的例子是路由群组分配同一个 PHP 命名空间给多个控制器，可以在群组属性数 组中使用 namespace 参数来指定群组中控制器的命名空间： 本文档由 Laravel 学院（LaravelAcademy.org）提供 22 Route::group(['namespace' => 'Admin'], function(){ // Controllers Within

命名空间给其下的多个控制器，可以在分 组属性数组中使用 namespace 来指定群组中所有控制器的公共命名空间： Route::group(['namespace' => 'Admin'], function(){ // 控制器在 "App\Http\Controllers\Admin" 命名空间下 Route::group(['namespace' => 'User'], function(){ 保护中排 除 webhook 处理器路由。 要实现这一目的，你需要在 VerifyCsrfToken 中间件中将要排除的 URL 添加 到 $except 属性： namespace App\Http\Middleware; use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier; app/Http/Middleware 目录下创建一个新的中间件类 OldMiddleware，在这 个中间件中，我们只允许提供的 age 大于 200 的访问路由，否则，我们将用户重定向到主 页： namespace App\Http\Middleware; use Closure; class OldMiddleware { /** * 返回请求过滤器

OrderChannel::class); 最后，可以将频道的授权逻辑放到频道类的 join 方法。join 方法中的代码等同于之前位于频道授权闭包中的处理逻辑。当然，你还可以使用频道模 型绑定： namespace App\Broadcasting; use App\User; use App\Order; class OrderChannel { /** * Create htmlspecialchars 函数的默认行为保持一致。如果 你想要维持不进行双重编码的旧状，可以使用 Blade::withoutDoubleEncoding 方法： namespace App\Providers; use Illuminate\Support\Facades\Blade; use Illuminate\Support\ServiceProvider; Bootstrap 3 链接，需要在 AppServiceProvider 的 boot 方法中调 用 Paginator::useBootstrapThree 方法： namespace App\Providers; use Illuminate\Pagination\Paginator; use Illuminate\Support\ServiceProvider;

驱动，不 过，编写自己的驱动很简单，你可以通过自己的搜索实现扩展 Scout。 你可以简单通过添加 Searchable trait 到模型让模型变得可搜索： namespace App; use Laravel\Scout\Searchable; use Illuminate\Database\Eloquent\Model; class Post 方法。 User 模型必须使用新的 Illuminate\Notifications\Notifiabletrait 以便邮件重置链接可以正常 发送： namespace App; use Illuminate\Notifications\Notifiable; use Illuminate\Foundation\Auth\User as Authenticatable; 仍然有替代方案，那就是在控制器构造函数中使用 Closure 来直接定义中间件。请注意，在使用 这个方案的时候，确保你所使用的 Laravel 版本高于 5.3.4： namespace App\Http\Controllers; use App\User; use Illuminate\Support\Facades\Auth; use App\Http\
