Koa 路由模块化

文件

• app.js

const Koa = require('koa');
const router = require('koa-router')();

    root: path.join(__dirname, 'view'),

// 1.引入模块化的子路由
var admin = require('./routes/admin.js');
var api = require('./routes/api.js');
 
// 2.绑定路由
router.use('/admin', admin);
router.use('/api', api);

router.get('/', (ctx) => {
    ctx.body = "这是一个首页"
});
 
app.use(router.routes());
app.use(router.allowedMethods());

// 3.引入子路由

// 4.绑定子路由
