此控件支持Josn,form,text类型

用法

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;});

参数：

disableBodyParser，可以动态设置不转换

app.use(async (ctx, next) => {  if (ctx.path === '/disable') ctx.disableBodyParser = true;  await next();});app.use(bodyparser());

onerror，用户化设置转换出错时的处理

app.use(bodyparser({  onerror: function (err, ctx) {    ctx.throw('body parse error', 422);  }}));

但是如果想要解析multipart/form-data类型,可以用koa-multer

const Koa = require('koa');const route = require('koa-route');const multer = require('koa-multer');const app = new Koa(); app.user(multer()); app.user(function *(){
    　　this.body = this.req.body; })
