uniapp 獲取當前定位

需要打開手機的gps開關，正常的授權也要有

判斷當前設備是否打開gps開關

 checkOpenGPSServiceByAndroid  () {
     let system = uni.getSystemInfoSync();// 獲取系統信息
     if (system.platform === 'android') { // 判斷平台
         var context = plus.android.importClass("android.content.Context");
         var locationManager = plus.android.importClass("android.location.LocationManager");
         var main = plus.android.runtimeMainActivity();
         var mainSvr = main.getSystemService(context.LOCATION_SERVICE);
         if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
             uni.showModal({
                 title: '提示',
                 content: '請打開定位服務功能',
                 showCancel: false, // 不顯示取消按鈕
                 success() {
                     if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
                         var Intent = plus.android.importClass('android.content.Intent');
                         var Settings = plus.android.importClass('android.provider.Settings');
                         var intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
                         main.startActivity(intent); // 打開系統設置GPS服務頁面
                     }
                 }
             });
         }
     } 
 },

獲取當前定位，經緯度轉地址

getnow() {
    uni.getLocation({
        type: 'wgs84',
        geocode: true,
        success: (res) =>{
            let point = new plus.maps.Point(res.longitude, res.latitude);
            plus.maps.Map.reverseGeocode(
                point, {},
                (event) =>{
                    let address = event.address; // 轉換后的地理位置
                    let point = event.coord; // 轉換后的坐標信息
                    let coordType = event.coordType; // 轉換后的坐標系類型
                    let reg = /.+?(省|市|自治區|自治州|縣|區)/g;
                    let addressList = address.match(reg).toString().split(",");
                    console.log(addressList,'位置信息')
                }
            )
        }
    });
},
