webman-多應用-多应用中间件配置

发布时间：2022-01-29 22:47:28编辑：雪饮阅读（）

 多應用中間件配置，這裏基於上篇中的多應用部署基礎上構建多應用中間件配置。

分別建立中間件：
    app/middleware/AccessControl.php:
    <?php
    namespace app\middleware;
    use Webman\MiddlewareInterface;
    use Webman\Http\Response;
    use Webman\Http\Request;
    class AccessControl implements MiddlewareInterface
    {
        public function process(Request $request, callable $next) : Response
        {
            echo "訪問了api中間件！\r\n";
            return $next($request);
        }
    }
    app/middleware/AdminAuthCheck.php:
    <?php
    namespace app\middleware;
    use Webman\MiddlewareInterface;
    use Webman\Http\Response;
    use Webman\Http\Request;
    class AdminAuthCheck implements MiddlewareInterface
    {
        public function process(Request $request, callable $next) : Response
        {
            echo "訪問了admin中間件001！\r\n";
            return $next($request);
        }
    }
    app/middleware/AuthCheck.php:
    <?php
    namespace app\middleware;
    use Webman\MiddlewareInterface;
    use Webman\Http\Response;
    use Webman\Http\Request;
    class AuthCheck implements MiddlewareInterface
    {
        public function process(Request $request, callable $next) : Response
        {
            echo "訪問了全局中間件！\r\n";
            return $next($request);
        }
    }
    app/middleware/SomeOtherClass.php:
    <?php
    namespace app\middleware;
    use Webman\MiddlewareInterface;
    use Webman\Http\Response;
    use Webman\Http\Request;
    class SomeOtherClass implements MiddlewareInterface
    {
        public function process(Request $request, callable $next) : Response
        {
            echo "訪問了admin中間件002！\r\n";
            return $next($request);
        }
    }
然後可以在config/middleware.php中將以上的中間件都應用到各個應用上：

 */

return [
    // 全局中间件
    '' => [
        app\middleware\AuthCheck::class,
    ],
    // api应用中间件
    'api' => [
        app\middleware\AccessControl::class,
    ],
    // admin应用中间件
    'admin' => [
        app\middleware\AdminAuthCheck::class,
        app\middleware\SomeOtherClass::class,
    ],
];
當然也可以在路由分組上進行應用，但那樣是路由中間件而不是多應用中間件的使用方式。
該多應用項目再次啓動並分別從不同的子應用訪問時：
[root@localhost webman]# /usr/local/php734/bin/php -c /usr/local/php734/lib/php.ini start.php start
Workerman[start.php] start in DEBUG mode
----------------------------------------- WORKERMAN -----------------------------------------
Workerman version:4.0.26          PHP version:7.3.4
------------------------------------------ WORKERS ------------------------------------------
proto   user            worker          listen                 processes    status
tcp     root            webman          http://0.0.0.0:8787    4             [OK]
tcp     root            monitor         none                   1             [OK]
---------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
訪問了全局中間件！
訪問了全局中間件！
訪問了admin中間件001！
訪問了admin中間件002！
訪問了全局中間件！
訪問了api中間件！

不同子應用訪問順序如：
[root@localhost ~]# elinks http://127.0.0.1:8787/Index/index --dump
   this is index
[root@localhost ~]# elinks http://127.0.0.1:8787/admin/Index/index --dump
   this is admin index
[root@localhost ~]# elinks http://127.0.0.1:8787/api/Index/index --dump
   this is api index
