路由

重要

koa 没有内封 router，需要安装插件 koa-router

相关文档：@koa/router

npm install @koa/router
npm install @types/koa__router -D

使用

import Koa from 'koa'
import Router from '@koa/router'

const app = new Koa()
const router = new Router()	

// 注意这里使用的是 router.routers()
app.use(router.routes())	

router.get('/', async (ctx: Koa.Context) => {
    ctx.body = {
        'path': ctx.request.path
    }
})

app.listen(3000, '0.0.0.0', () => {
    console.log('服务器启动成功')
})

拆分

main.ts

import Koa from 'koa'
import routers from './router'

const app = new Koa()

app.use(routers.routes()).use(routers.allowedMethods()) 	

app.listen(3000, '0.0.0.0', () => {
    console.log('服务器启动成功')
})

router.ts

import Router from "@koa/router";
import publicRouter from "./publicRouter";
import adminRouter from './adminRouter'

const routers = new Router()

routers
    .use('/public', publicRouter.routes(), publicRouter.allowedMethods())	
	.use(adminRouter.routes(), adminRouter.allowedMethods())

export default routers

publicRouter.ts

import Router from "@koa/router";
import Koa from 'koa'

const publicRouter = new Router()

publicRouter
    .get('/word-day', async function (ctx:Koa.Context){})
    .get('/word-day/:id', async function (ctx:Koa.Context){})

export default publicRouter

adminRouter.ts

import Router from '@koa/router'
import Koa from "koa";

const adminRouter = new Router().prefix('/admin') 	 // 或 new Router({prefix: '/public'})

adminRouter
    .post('/word-day', async function (ctx:Koa.Context){})
    .put('/word-day', async function (ctx:Koa.Context){})
    .delete('/word-day', async function (ctx:Koa.Context){})

export default adminRouter
