【报Bug】uni.uploadFile小程序端不发请求，H5端多次请求

示例代码：

uni.$on('uAvatarCropper', uri => {  
      const { config, auth } = getApp().globalData  
      const url = `${config.api}/test/file?access_token=${auth.access_token}`  
      const files = [{ uri }]  
      console.log({ url, files })  
      uni.showLoading({ title: '上传中' })  
      uni.uploadFile({  
        url,  
        files  
      }).then(([ err, res ]) => {  
        uni.hideLoading()  
        if (err) {  
          uni.showModal({  
            title: '上传失败',  
            content: err,  
            showCancel: false  
          })  
        } else {  
          uni.showToast({ title: '上传成功' })  
          this.form.avatar = uri  
          getApp().globalData.user.avatar = uri  
        }  
      })  
    })  
  }
