定位代码如下：

         wx.getLocation({
                type: "gcj02",
                altitude:false,
                isHighAccuracy:true,
                highAccuracyExpireTime:3000,
                success:function(res){
                    console.log('位置获取成功', res);
                    res.latitude = formatNumber(res.latitude);
                    res.longitude = formatNumber(res.longitude);
                    resolve(res)
                },
                fail:function(err){
                    console.log('位置获取失败', err);
                    uni.hideLoading();
                    uni.showModal({
                        content: JSON.stringify(err),
                        showCancel: false,
                        confirmText: "确定",
                        confirmColor: "#52a2d8",
                        success(){
                            uni.navigateBack();
                        }
                    });
                    reject('error');
                },
                complete:function(data){
                    console.log('位置获取完成，无论成功或失败，均触发', data);
                }
            });

在fail的方法中配置了提示弹框，华为p40、荣耀v30机型上只要定位就会出现fail中的弹框，如下：
