uniapp授权位置权限（GPS位置）的例子

# 第一次调用定位接口时，会弹窗请求是否授权
//获取定位
            getLocation() {
                uni.getLocation({
                    type: 'wgs84',
                    success:  (res) => {//授权成功后，调用
                                console.log(res,'当前位置的经纬度')
                                var latitude = res.latitude
                                var longitude = res.longitude
                                var speed = res.speed
                                var accuracy = res.accuracy;
                                this.getLocal(latitude,longitude)
                    },
                        fail(err) {//授权失败后，调用，可以在这儿调用下面的例子 再次进行授权
                            console.log(err,'eee')
                            uni.showToast({
                                title:'授权未通过',
                                icon: 'none'
                            })
                        }
                });
            },

华为对位置权限要求比较严格，第二次不要循环弹出权限窗口。
