koa获取get参数

query

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

const app = new Koa();

// http://localhost:8080/?a=1&b=2
router.get("/", async ctx => {
  console.log(ctx.query); //{a:1,b:2}
  console.log(ctx.querystring); // a=1&b=2
  console.log(ctx.request.query); //{a:1,b:2}
  console.log(ctx.request.querystring); //a=1&b=2
  ctx.body = "home";
});

app
  .use(router.routes()) // 启动路由
  .use(router.allowedMethods());

app.listen(8080);

params

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

const app = new Koa();

// http://localhost:8080/news/aaa
router.get("/news/:id", async ctx => {
  console.log(ctx.params); //{id:'aaa'}
  ctx.body = "news";
});

app
  .use(router.routes()) // 启动路由
  .use(router.allowedMethods());

app.listen(8080);

和vue是一模一样的呀
