我试了wx.authorize授权但是返回{“errMsg”:“authorize:fail:require permission desc”}。以下是我的代码，请帮忙。谢

getPermission2: function (e) {
    wx.getSetting({
      success: function(res) {
        if (!res.authSetting[‘scope.userLocation’]) {
          wx.authorize({
            scope: ‘scope.userLocation’,
            success: function() {
              wx.showToast({
                title: ‘授权成功1’
              })
            },
            fail: function(errorRes){
              var bbb = JSON.stringify(errorRes);
              page.setData({ errorMsg:bbb});
            }
          })
        }
      }
    })
  }
