小程序app.onLaunch里获取用户信息，失败则跳转到err页面，代码如下 wx.getUserInfo({     success: res => {         that.globalData.userInfo = res.userInfo         logger.info('app getUserInfo suss:',res.userInfo)     },     fail: res => {         logger.info('app getUserInfo fail')         that.globalData.errObj = that.getErrObj('获取用户标识失败', res,101)         wx.navigateTo({             url: '/pages/index/err',             suss:res=>{             logger.info('app navigateTo err suss',res)             },             fail: res => {             logger.info('app navigateTo err fail', res)             }         })     } }) 运行后能正确跳转到/pages/index/err页面，但是并没有打印出app navigateTo err suss或app navigateTo err fail，控制台报错 navigateTo with an already exist webviewId 197,位置介于err页面的onready和onshow之间。 2017/10/24 10:52:31 INFO app getUserInfo fail logger.js?
