小程序里授权相册问题的有效解决办法及代码示例

<button type=&#39;primary&#39;  size=&#39;mini&#39;  open-type="openSetting"   bindopensetting=&#39;handleSetting&#39;   >

去授权</button>;

4、在打开

handleSetting: function (e) {

    let that = this;    // 对用户的设置进行判断，如果没有授权，即使用户返回到保存页面，显示的也是“去授权”按钮；同意授权之后才显示保存按钮

    if (!e.detail.authSetting['scope.writePhotosAlbum']) {

      wx.showModal({

        title: '警告',

        content: '若不打开授权，则无法将图片保存在相册中！',

        showCancel: false

      })

      that.setData({

        saveImgBtnHidden: false,

        openSettingBtnHidden: true

      })

    } else {

      wx.showModal({

        title: '提示',

        content: '您已授权，赶紧将图片保存在相册中吧！',

        showCancel: false

      })

      that.setData({

        saveImgBtnHidden: true,

        openSettingBtnHidden: false

      })

    }

  },
