一、封裝的upload方法能看懂就看 看不懂直接使用 

       1.支援base64和普通表單等檔案上傳方式(會自動判斷方式)

        2.呼叫時候只需要傳入一個要上傳到阿里雲的地址即可

        3.返回結果是個json物件 示例如下:

           path：返回上傳成功後oss圖片地址.

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