Koa2 Route(二)

lixin-macbook:koa-example lixin$ npm install koa-router --save

// 引入koa
const Koa = require("koa");
// 引入koa-router
const Router = require('koa-router');
// 创建Koa实例
const app = new Koa();
// 创建Router实例
const router = new Router();

// 配置路由
// curl -X GET http://localhost:8080?name=zhgnsan
router.get('/', async (ctx, next) => {
    // let query = ctx.query;
    // {name : "zhgnsan"}
    // ctx.body = 'GET Hello World! request param name:' + query.name;

    // name=zhgnsane
    // let query = ctx.querystring;
    // ctx.body = 'GET Hello World! request param name:' + query;


    const request = ctx.request;
    const response = ctx.response;
    
    // let query = request.query;
    // {name : "zhgnsan"}
    // ctx.body = 'GET Hello World! request param name:' + query.name;

    // {
    //   method: 'GET',
    //   url: '/?name=zhgnsan',
    //   header: {
    //     host: 'localhost:8080',
    //     'user-agent': 'curl/7.64.1',
    //     accept: '*/*'
    //   }
    // }
    console.log(request);

    let query = request.querystring;
    // name=zhgnsane
    ctx.body = 'GET Hello World! request param name:' + query;
});


// 配置动态路由
// curl -X GET http://localhost:8080/get/zhgnsan
router.get('/get/:name', async (ctx, next) => {
    let name = ctx.params.name;
    ctx.body = "GET /get/" + name;
});


// 配置中间件
app.use(router.routes()).use(router.allowedMethods());
// 监听端口
app.listen(8080);

lixin-macbook:koa-example lixin$ node app.js 

// GET请求
lixin-macbook:~ lixin$ curl -X GET http://localhost:8080?name=zhgnsan
GET Hello World! request param name:name=zhgnsan

// GET动态路由
lixin-macbook:~ lixin$ curl -X GET http://localhost:8080/get/zhgnsan
GET /get/zhgnsan
