webman不支持在控制器中定義中間件，因?yàn)檫w移tp代碼自己實(shí)現(xiàn)了控制器中間件支持，分享同時也請大家指點(diǎn)指點(diǎn)。
貼代碼：
首先創(chuàng)建自己的控制器中間件接口

<?php

namespace app\common\middleware;

use Webman\Http\Request;
use Webman\Http\Response;

interface ControllerMiddlewareInterface
{

    /**
     * 控制器專用中間件接口
     */
    public function process(Request $request): ?Response;

}

創(chuàng)建webman中間件以調(diào)用自己的控制器中間件

<?php

namespace app\common\middleware;

use Webman\Http\Request;
use Webman\Http\Response;
use Webman\MiddlewareInterface;

class ControllerMiddleware implements MiddlewareInterface
{

    /**
     * 實(shí)現(xiàn)控制器中間件處理
     * @param Request $request
     * @param callable $handler
     * @return Response
     */
    public function process(Request $request, callable $handler) : Response
    {
        $controllerClass = $request->controller;

        try{
            $middlewareConfig = $controllerClass::middleware;
        }catch (\Throwable $e){
            //沒有定義控制器中間件
            $middlewareConfig = [];
        }
        if($middlewareConfig){
            //如果存在中間件，則調(diào)用控制器中間件
            foreach ($middlewareConfig as $middlewareClass) {
                /**
                 * @var ControllerMiddlewareInterface $middleware
                 */
                $middleware = new $middlewareClass();

                //調(diào)用中間件，若有響應(yīng)則中斷請求
                if($res = $middleware->process($request)){
                    return $res;
                }
            }
        }

        return $handler($request);
    }
}

實(shí)現(xiàn)一個控制器中間件，demo如下

<?php

namespace app\common\middleware;

use Webman\Http\Request;
use Webman\Http\Response;

/**
 * 鑒權(quán)中間件
 */
class AuthMiddleware implements ControllerMiddlewareInterface
{

    /**
     * @param Request $request
     * @return Response
     */
    public function process(Request $request) : ?Response
    {
        if($request->isAjax()){
            return new Response(200, [], '不允許ajax提交');
        }

        return null;
    }
}

將實(shí)現(xiàn)的控制器中間件添加到控制器中

<?php
namespace plugin\admin\app\controller;

use app\BaseController;

class Index extends BaseController
{
    /**
     * 控制器中間件
     */
    const middleware = [
        \app\common\middleware\AuthMiddleware::class
    ];

    public function index()
    {
        return "hello admin.";
    }
}

最后，將webman中間件添加到配置中（middleware.php）

<?php
use App\common\middleware\ControllerMiddleware;

return [
    '' => [
        //...你的其他中間件配置

        //控制器中間件
        ControllerMiddleware::class

    ]
];
