koa2怎么获取post请求参数？

https://www.npmjs.com/package/koa-bodyparser

var Koa = require('koa'); var bodyParser = require('koa-bodyparser');

var app = new Koa(); app.use(bodyParser());

app.use(async ctx => { // the parsed body will store in ctx.request.body // if nothing was parsed, body will be an empty object {} ctx.body = ctx.request.body; });

使用postman或curl测试

@i5ting 是koa2不支持这些中间件了吗

https://github.com/17koa/koa-generator/blob/tpl_2.x/app/app.js

你可不用中间件 let postdata = ""; ctx.req.addListener('data', (data) => { postdata += data }) ctx.req.addListener("end", function() { console.log(postdata); }) ```
