q.respond

该仓库是 Koa response 处理的标准中间件，但该仓库的 response 类型仅仅是符合个人风格的统一格式，不适用于所有业务。

• install: npm i --save q-respond

• import and load:

const Koa = require('koa')
const responseHandler = require('q-respond')
const router = require('./routes')

// ...other imports

const app = new Koa()

// you can set default options for responses
const defaultOptions = {
  merge: true
  successMessage: 'operate successfully',
  errorMessage: 'operate failure'
}

app.use(responseHandler(defaultOptions))
app.use(router.routes()).use(router.allowedMethods())

// in your controllers
const routes = router.get('/ok', ctx => {
  ctx.res.ok({
    data: 'ok data',
    code: 200
  })
})

Method (ctx.res.{method_name})	params	action
