# 文件上传 Post with form-data
主要目的是为了上传
koa-v1 要是用 koa-multer-v0.0.2 对应的 multer < 1，所以本处需要指定版本安装
```shell
$ npm install --save koa-multer@0.0.2
```
Usage
```javascript
var app = require('koa')()
, koa = require('koa-router')()
, logger = require('koa-logger')
, json = require('koa-json')
, views = require('koa-views')
, onerror = require('koa-onerror');
var multer = require('koa-multer');
app.use(multer({ dest: './uploads/'}));
```
You can access the fields and files in the request object:
```javascript
router.post('/post/formdata', function *(next) {
console.dir(this.req.body)
console.dir(this.req.files)
this.body = 'this a users response!';
});
```
重要提示： Multer will not process any form which is not multipart/form-data

测试
```shell
$ npm test
```
使用Postman测试
