小程序在体验版中无法正常拉起位置信息授权框，但是真机调试以及工具中均可以正常拉起。体验版返回的errMsg提示"getLocation:fail require permission desc"。但是app.json中已正常配置permission信息。

app.json:

"permission": {
    "scope.userLocation": {
      "desc": "你的位置信息将用于小程序定位"
    }
  },

js:

wx.getLocation({
      type: 'gcj02',
      success: res => {
        that.getNowSituation(res)
      },
      fail: res => {
        console.log(res)
        wx.getSetting({
          success: (res) => {
            if (!res.authSetting['scope.userLocation']) {
              wx.hideLoading()
              wx.showModal({
                title: '提示',
                content: '尚未授权获取位置信息,请先授权',
                confirmText: '前往授权',
                success(res) {
                  if (res.confirm) {
                    wx.openSetting({
                      complete: (res) => {
                        wx.getLocation({
                          type: 'gcj02',
                          success: res => {
                            that.getNowSituation(res)
                          }
                        })
                      },
                    })
                  } else if (res.cancel) {
                    wx.navigateBack()
                  }
                }
              })
            }
          },
        })
      }
    })

体验版提示：

{errMsg:"getLocation:fail require permission desc"}
