 一、封装的upload方法能看懂就看 看不懂直接使用 

       1.支持base64和普通表单等文件上传方式(会自动判断方式)

        2.调用时候只需要传入一个要上传到阿里云的地址即可

        3.返回结果是个json对象 示例如下:

           path：返回上传成功后oss图片地址.

{
  "code": 200,
  "msg": "成功",
  "data": {
    "path": "http://xzfct.oss-cn-beijing.aliyuncs.com/upload/wechat/20180927/a848dc251ae60074ad233babaa711e7c.jpeg"
  }
}
