Question

这里我使用谷歌地图API，用户搜索他们的区域意味着我想得到纬度和logidute并存储在我的数据库中，我不知道该怎么办，我是google地图集成的新手请帮我一些一个

      // This sample uses the Place Autocomplete widget to allow the user to search
      // for and select a place. The sample then displays an info window containing
      // the place ID and other information about the place that the user has
      // selected.

      // This example requires the Places library. Include the libraries=places
      // parameter when you first load the API. For example:
      // <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">

      function initMap() {
        var map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: -33.8688, lng: 151.2195},
          zoom: 13
        });

        var input = document.getElementById('pac-input');

        var autocomplete = new google.maps.places.Autocomplete(input);
        autocomplete.bindTo('bounds', map);

        map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

        var infowindow = new google.maps.InfoWindow();
        var marker = new google.maps.Marker({
          map: map
        });
        marker.addListener('click', function() {
          infowindow.open(map, marker);
        });

        autocomplete.addListener('place_changed', function() {
          infowindow.close();
          var place = autocomplete.getPlace();
          if (!place.geometry) {
            return;
          }

          if (place.geometry.viewport) {
            map.fitBounds(place.geometry.viewport);
          } else {
            map.setCenter(place.geometry.location);
            map.setZoom(17);
          }

          // Set the position of the marker using the place ID and location.
          marker.setPlace({
            placeId: place.place_id,
            location: place.geometry.location
          });
          marker.setVisible(true);

          document.getElementById('place-name').textContent = place.name;
          document.getElementById('place-id').textContent = place.place_id;
          document.getElementById('place-address').textContent =
              place.formatted_address;
          infowindow.setContent(document.getElementById('infowindow-content'));
          infowindow.open(map, marker);
        });
      }

Answer 1

如documentation所述，您可以使用Google地图地理编码API并使用地址进行查询，而api将使用该地址的地理编码（包括纬度和经度）进行回复。例如，以下请求，

curl "https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY"

，将与

一起回复

{
...    
"geometry" : {
   "location" : {
     "lat" : 37.4223664,
     "lng" : -122.084406
    },
    ...
},
...
}

您可以找到详细的示例here。
