imageClick(){
    var that = this;
    wx.chooseImage({  //从本地相册选择图片或使用相机拍照
      count: 1, // 默认9
      sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认二者都有
      sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有

      success: function (res) {

        // 返回选定照片的本地文件路径列表，tempFilePath可以作为img标签的src属性显示图片
        var tempFilePaths = res.tempFilePaths
        var uid = that.data.uid
        wx.uploadFile({
          url: 'https://www.qqbee.net/api/index/uploadimg',
          filePath: tempFilePaths[0],
          name: 'file',
          formData: {
            uid
          },
          success: function (res) {
            const data = res.data
            const obj = JSON.parse(data); 
            const image = obj.image
            that.setData({
              image 
            })
          }
        })
