## koa2-http-proxy-middleware

> koa2请求转发中间件

## 用法

**初始化中间件**

``` javascript

const Koa = require('koa')

const app = new Koa()

const PORT = 3000

const koaBodyparser = require('koa-bodyparser')

const httpProxy = require('koa2-http-proxy-middleware')

// 因中间件中需要解析body中的参数，故先添加该中间件

app.use(koaBodyparser())

// apiHost即是你要转发请求到后端的host，其他的参数可以参考axioshttps://github.com/axios/axios

app.use(httpProxy({

  apiHost: 'xxx.yyy.com'

}))

app.listen(PORT, () => {

  console.log(`app start at: ${PORT}`)

})

```

**转发请求**

在你的路由controller中使用如下方法转发请求

``` javascript

async pages (ctx, next) {

  // 这里可以做一些请求之前需要处理的事情

  const data = await ctx.httpProxy()

  // 这里可以做一些请求之后需要处理的事情

  ctx.body = data

}

```
