Koa配置路由

npm install koa --save
npm install koa-router --save

var koa = require('koa');
var Router = require('koa-router');
var app = new koa();
var router = new Router();


router.get('/', async (ctx) => {
    ctx.body = "首页";
})
router..get('/news', async (ctx) => {
    ctx.body = "新闻";
})

// 获取get传值
router.get('/newsContent', async (ctx) => {
    // http://localhost:3000/newsContent?id=3
    console.log(ctx.query.id) //获取get传值 3
    ctx.body = "新闻详情";
})

// 配置动态路由
router.get('/newsCtx/:id', async (ctx) => {
    // http://localhost:3000/newsCtx/koa
    console.log(ctx.params) //获取动态路由返回值
    ctx.body = "新闻详情";
})

app.use(router.routes())
app.use(router.allowedMethods())

app.listen(3000);
