在混合app开发过程中使用百度地图api的出现坐标偏差的解决

var lat,long;
var posOptions = {enableHighAccuracy: true};//设置定位精度
$cordovaGeolocation
  .getCurrentPosition(posOptions)
  .then(function (position) {
    var lo=position.coords.longitude;//经度
    var la=position.coords.latitude;//纬度
    //开始转换坐标(GPS---百度坐标)
    $http({
      method: ‘GET‘,
      url: ‘http://api.map.baidu.com/geoconv/v1/?coords=‘+lo+‘,‘+la+‘&from=1&to=5&ak=你的秘钥‘
    }).then(function successCallback(response) {   //转换完成
      long=response.data.result[0].x;
      lat=response.data.result[0].y;
      // 调用百度地图api显示
   var map = new BMap.Map("map");
      var pPoint = new BMap.Point(long, lat);
      map.centerAndZoom(pPoint, 18);
      var geoc = new BMap.Geocoder();
      var mk = new BMap.Marker(pPoint);
      map.addOverlay(mk);
geoc.getLocation(new BMap.Point(long, lat), function(rs){
  if(rs){
    var location=rs.addressComponents;    $scope.myLocation=location.province+location.city+location.district+location.street+location.streetNumber+rs.surroundingPois[0].title;
    console.log($scope.myLocation);
  }
});

    }, function errorCallback(response) {
      window.alert("转换坐标失败，请检查网络")
    });

  }, function(err) {
    window.alert("获取地理位置失败")
  });
