微信小程序在华为鸿蒙4.0系统上定位失败是什么原因？

onShow(){
    this.glApp.doLocation((res) => {
    this.getList();
})
}

export const doLocation = (completed) => {
    console.log("start")
    uni.getLocation({
        isHighAccuracy: true,
        type: 'gcj02',
        success(res) {
            console.log("succcc")
            uni.setStorageSync('locMess', res)
            completed(res)
        },
        fail(res) {
            console.log("errrr")
            uni.removeStorageSync('locMess')
            uni.hideLoading()

            uni.getSetting({
                success(res) {
                    console.log(res.authSetting)
                    if (res.authSetting['scope.userLocation'] == false) {
                        //引导用户开启定位权限
                    } else {
                        uni.showToast({
                            icon: "none",
                            title: '定位失败，请检查设置',
                            duration: 2000,
                            success() { completed() },
                            fail() { completed() }
                        })
                    }
                }
            })
        }
    })
