微信小程序在华为鸿蒙4.0系统上定位失败，如何解决？

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)
