使用模仿formdata 上传多文件

	npm install [@macrocc](/user/macrocc)/formdata-polyfill

然后

import FormData from '[@macrocc](/user/macrocc)/formdata-polyfill'

	const formData = new FormData((path) => wx.getFileSystemManager().readFileSync(path))
    formData.append('test':0)
    formData.appendFile('files',path)
    const [data, contentType] = formData.generate()
    wx.request({
          url:'baidu.com',
          data,
          header:{ contentType }
    })
