## README

# wx-formdata
在小程序中使用formdata上传数据，可实现多文件上传

# 用法
跟浏览器中的FormData对象类似
引入js文件
```js
const FormData = require('./formData.js')
```
new一个FormData对象
```js
let formData = new FormData();
```
调用它的[append()](#formdataappend)方法来添加字段或者调用[appendFile()](#formdataappendfile)方法添加文件
```js
formData.append("name", "value");
formData.appendFile("file", filepath);
```
添加完成后调用它的[getData()](#formdatagetdata)生成上传数据，之后调用小程序的wx.request提交请求
```js
let data = formData.getData();
wx.request({
  url: 'https://接口地址',
  header: {
    'content-type': data.contentType
  },
  data: data.buffer,
});
```
