小程序端

 wx.uploadFile({
          url: 'https://youmingyu.oicp.vip/wx/shop/upload',
          filePath: path,
          name: 'wximag',
          success: res => {
            resolve(res)
          },
          fail: err=>{
            reject(err)
          }
        })
      })

        return "ok"

目的是要写入到数据库，所以采用保存后读取又删除。 tempfile使用失败
