} 而在 Laravel 6.0 中，该业务逻辑可以被提取到任务中间件中，从而 将你的任务 handle 方法从频率限制中解放出来： Middleware; use Illuminate\Support\Facades\Redis; 本文档由学院君提供 学院君致力于提供优质 Laravel 中文学习资源：https://xueyuanjun 创建完中间件后，可以通过在任务类的 middleware 方法中返回中间 件数组来将其追加到队列任务中： use App\Jobs\Middleware\RateLimited; /** * Get the middleware the job should pass through. * * @return array */ public function middleware() { return Homestead 站点的请求重定向到 Homestead 虚拟机。在 Mac 和 Linux 系统中，该文件位于 /etc/hosts，在 Windows 系统中， 该文件位于 C:\Windows\System32\drivers\etc\hosts。我们 以 homestead.test 域名映射为例，添加到 hosts 文件的记录如下 所示： 192.168.10.10 homestead.test

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： Middleware; use Closure; class RoleMiddleware { /** * 运行请求过滤器. * * @param 指定，多个参数可以通过 逗号进行分隔： 本文档由 Laravel 学院（LaravelAcademy.org）提供 3 Route::put('post/{id}', ['middleware' => 'role:editor', functio n ($id) { // }]); 更多关于中间件的内容，请查看中间件一节。 测试革新 Laravel 中内置 特性已经被废弃并且会在 2015 年 12 月份的 Laravel 5.2 中被完全移除：  中间件中的路由过滤器  Illuminate\Contracts\Routing\Middleware，中间件中不再需要任何 contract， Illuminate\Contracts\Routing\TerminableMiddleware 被废弃，在中间件中定义一个 terminate

route middleware groups. * * @var array */ protected $middlewareGroups = [ 'web' => [ \App\Http\Middleware\EncryptCookies::class, \Illuminate\Cookie\Middleware\AddQ ss, \Illuminate\Session\Middleware\StartSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class, \App\Http\Middleware\VerifyCsrfToken::class, ], 'api' => [ 'throttle:60,1', ], ]; 然后，web 组像这样分配给路由： Route::group(['middleware' => ['web']], function () { // }); 访问频率限制 一个新的访问频率限制中间件已经被内置到框架中，从而允许你轻松限制给定 IP 地址在

er}/status', function (Order $order) { // Access token has "check-status" scope... })->middleware('scope:check-status'); 最后，Passport 还支持从 JavaScript 应用访问你的 API，而不必担心访问令牌传输，Passport 通 过加密 JWT * * @return void */ public function __construct() { $this->middleware(function ($request, $next) { $this->projects = Auth::user()->projects; 中间件命名空间修改 罗列在 HTTP Kernel 的$routeMiddleware 属性中的 can 中间件需要作如下修改： 'can' => \Illuminate\Auth\Middleware\Authorize::class, can 中间件认证异常 如果用户没有认证的话can中间件会抛出 Illuminate\Auth\AuthenticationException异常实例，

there are other migrations, which are added by the Laravel framework itself for it’s authentication system. But let’s focus on creating a new table, let’s call it dogs . Go in the up() function of the routes are loaded by the RouteServiceProvider and all of them will | be assigned to the "web" middleware group. Make something great! | */ Route::get('/newdog', function () { return view('newdog'); the DigitalOcean panel) In Advanced Settings you can configure more details such as the Operating System, Database and PHP version: 86 I picked Postgres because I like that more, but it’s just a preference

few examples that we think make good bullet points:  Bundles are Laravel's modular packaging system. The Laravel Bundle Repository is already populated with quite a few features that can be easily output the paging links in your view. Laravel automatically does the rest. Laravel's pagination system was designed to be easy to implement and easy to change. It's also important to note that just because Bundle::start.  Allow the registration of custom database drivers.  New, driver based authentication system.  Added Input::json() method for working with applications using Backbone.js or similar. 
