小程序在7.0.18下,无法获取"writePhotosAlbum"的授权,降级至7.0.17后正常。

Appid:wx1b712a36c88933a4

代码片段：

wx.getSetting({
      success(res) {
        let wpa = res.authSetting["scope.writePhotosAlbum"];
        console.log(res.authSetting)//7.0.18下无该权限
        if (wpa == false || wpa == undefined) {
          wx.showModal({
            title: "提示",
            content: "保存照片功能,需要您的相册访问授权,请先授权再使用该功能。",
            confirmText: "授权",
            cancelText: "取消",
            success(res) {
              if (res.confirm) {
                wx.openSetting({})
              } else {
                return;
              }
            }
          })
        } else {
          wx.showLoading({
            title: '正在保存...',
            mask: true
          })
          setTimeout(() => {
            wx.saveImageToPhotosAlbum({
              filePath: that.data.shareImagePath,
              success(res) {
                wx.showToast({
                  title: '保存成功',
                  icon: 'none'
                })
                setTimeout(() => {
                  wx.hideLoading()
                  that.setData({
                    isPhotoModel: false,
                    isCanvas: false
                  })
                }, 1000)
              },
              fail() {
                wx.showToast({
                  title: '保存失败，请刷新页面重试',
                  icon: 'none'
                })
                setTimeout(() => {
                  wx.hideLoading()
                  that.setData({
                    isPhotoModel: false,
                    isCanvas: false
                  })
