Node學習記錄: koa

官方文檔：koa
初識階段固然是看阮一峯的Koa 框架教程

前端用koa模擬動態接口

實戰教程（6）使用fetch有一部分講解

npm install koa koa-body koa-router --save-dev

var app = require('koa')();
var router = require('koa-router')();
var koaBody = require('koa-body')();

router.get('/', function *(next) {
    this.body = 'hello koa !'
});

router.get('/api', function *(next) {
    this.body = 'test data'
});
router.get('/api/1', function *(next) {
    this.body = 'test data 1'
});
router.get('/api/2', function *(next) {
    this.body = {
        a: 1,
        b: '123'
    }
});

router.post('/api/post', koaBody, function *(next) {
    console.log(this.request.body)
    this.body = JSON.stringify(this.request.body)
});

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

app.listen(3000);
