这种情况在express下怎么添加中间件？

Question

express里一般这样添加中间件

但我的把路由并到一起了，用了一个循环来读取

AppRoutes.forEach(route => {
        app[route.method](route.path, (request: Request, response: Response, next: Function) => {
            route.action(request, response)
                .then(() => next)
                .catch(err => next(err));
        });
    });

路由文件 ：

import {postGetAllAction} from "./controller/PostGetAllAction";
import {postGetByIdAction} from "./controller/PostGetByIdAction";
import {postSaveAction} from "./controller/PostSaveAction";
import {getAdmin} from './controller/GetAdmin'
/**
 * All application routes.
 */
export const AppRoutes = [
    {
        path: "/admin",
        method: "get",
        action: getAdmin
    },
    {
        path: "/posts",
        method: "get",
        action: postGetAllAction
    },
    {
        path: "/posts/:id",
        method: "get",
        action: postGetByIdAction
    },
    {
        path: "/posts",
        method: "post",
        action: postSaveAction
    }
];

这种情况下我怎么在循环里添加中间件？

Answer 1

// 多个handler 可以直接使用数组（配置中action换成数组类型），express是支持的

AppRoutes.forEach(route => {

    app[route.method](route.path, route.action);
});
