微信小程序weui uploader的使用

js

uplaodFile(files) {
    // 文件上传的函数，返回一个promise
    return new Promise((resolve, reject) => {
      let that = this
      var urls = []
      console.log('upload files', files)
      wx.uploadFile({
        filePath: files.tempFilePaths[0],
        name: 'hwpic',		//key-value的key的名字
        url: 'http://localhost:8080/index/photo', //后端的接口
        success(res) {
          console.log(res)
          var data = JSON.parse(res.data)
          if (data.status == 1) {
            urls.push(data.url)	//必须返回一个url
            that.setData({
              imgUrl: urls,
            })
            resolve({
              urls:urls
            });
          }
        }
      })
      setTimeout(() => {
        reject('some error')
      }, 1000)
    })
  },
