已经生成海报但是不能保存，

//保存的  onImgOK(e) {    console.log(e)    this.imagePath = e.detail.path;    console.log(e.detail.path)    this.setData({      image: this.imagePath    })    if (this.isSave) {      this.saveImage(this.imagePath);    }  },  saveImage(imagePath = '') {    console.log(111, '刚进来',)    console.log(imagePath)    console.log(222, '判断条件', this.isSave)    if (!this.isSave) {      this.isSave = true;      console.log(333, this.data.template)      this.setData({        paintPallette: this.data.template,      });    } else if (imagePath) {      console.log(imagePath)      this.isSave = false;      wx.saveImageToPhotosAlbum({        filePath: imagePath,      });    }  },

    <painter     customStyle='margin-left: 80rpx;height: 1000rpx;'    customActionStyle="{{customActionStyle}}"    dancePalette="{{template}}"    palette="{{paintPallette}}"    bind:imgOK="onImgOK"     bind:touchEnd="touchEnd"     action="{{action}}"     />

 saveImgToLocal() {      console.log(444444)      const that = this;      setTimeout(() => {        console.log('that.canvasWidthInPx', that.canvasWidthInPx)        console.log('that.canvasHeightInPx', that.canvasHeightInPx)        wx.canvasToTempFilePath({          canvasId: 'photo',          destWidth: that.canvasWidthInPx,          destHeight: that.canvasHeightInPx,          success: function (res) {            that.getImageInfo(res.tempFilePath);            console.log('6666-请求成功', res)          },          fail: function (error) {            console.log('77777-请求失败', error)            console.error(`canvasToTempFilePath failed, ${JSON.stringify(error)}`);            that.triggerEvent('imgErr', {              error: error            });          },        }, this);      }, 300);    },
