如何以编程方式与Google Maps分享我的行程？

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap" async defer></script>

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: YOUR_LATITUDE, lng: YOUR_LONGITUDE},
    zoom: ZOOM_LEVEL
  });
}

function calculateAndDisplayRoute(directionsService, directionsRenderer) {
  directionsService.route(
    {
      origin: ORIGIN_ADDRESS,
      destination: DESTINATION_ADDRESS,
      travelMode: 'DRIVING'
    },
    function(response, status) {
      if (status === 'OK') {
        directionsRenderer.setDirections(response);
      } else {
        window.alert('Directions request failed due to ' + status);
      }
    }
  );
}

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    center: {lat: YOUR_LATITUDE, lng: YOUR_LONGITUDE},
    zoom: ZOOM_LEVEL
  });

  var directionsService = new google.maps.DirectionsService();
  var directionsRenderer = new google.maps.DirectionsRenderer();
  directionsRenderer.setMap(map);

  calculateAndDisplayRoute(directionsService, directionsRenderer);
}

var origin = encodeURIComponent(ORIGIN_ADDRESS);
var destination = encodeURIComponent(DESTINATION_ADDRESS);
var url = 'https://example.com/share?origin=' + origin + '&destination=' + destination;
