从地点获取街道号码 API

Question

我正在使用 Google 地点 API 使输入目的地变得容易。理想情况下，我希望用户能够开始输入语义名称（例如斯坦福大学）并让 Places API 自动建议一个选项。我正在使用 Geocoder 返回的结果来获取结构化位置数据。但是，我注意到如果我输入 "Stanford University" 的查询，返回的地理编码结果不包含 street_number 的键。有谁知道如何使用 Places API 将地点地理编码为包含 street_number 的地理编码结果？

Answer 1

如果我查找 Stanford University with the places service，它 returns place_id ChIJneqLZyq7j4ARf2j8RBrwzSk。 getDetails 请求 place_id returns 地址组件数组，条目类型为 street_number。

var map;

var service;
var data_id;
var count = 1;
var request;
var placeIDs = [];

function initialize() {
    map = new google.maps.Map(document.getElementById('map-canvas'), {
        center: new google.maps.LatLng(19.12455, 72.929158),
        zoom: 11
    });
    infowindow = new google.maps.InfoWindow();

    var bounds = new google.maps.LatLngBounds();
    var errorCnt = 0;
    var successCnt = 0;
    for (var i = 0; i < data.length; i++) {

        placeIDs[i] = data[i]['place_id'];


        infoWindow = new google.maps.InfoWindow();
        service = new google.maps.places.PlacesService(map);

        service.getDetails({
            placeId: placeIDs[i]
        }, function (place, status) {
            if (status == google.maps.places.PlacesServiceStatus.OK) {
                successCnt += 1;
                var marker = new google.maps.Marker({
                    map: map,
                    position: place.geometry.location,
                    title: place.name
                });
                for (var i = 0; i < place.address_components.length; i++) {
                    for (var j = 0; j < place.address_components[i].types.length; j++) {
                        if (place.address_components[i].types[j] == "street_number") {
                            document.getElementById('info').innerHTML += "street_number:" + place.address_components[i].long_name + "<br>";
                        }
                    }
                }
                console.log(place);
                bounds.extend(marker.getPosition());
                google.maps.event.addListener(marker, 'click', function () {
                    infowindow.setContent(place.name + "<br>" + place.types + "<br><a href='" + place.url + "'>url</a>");
                    infowindow.open(map, this);

                map.fitBounds(bounds);
            } else {
                document.getElementById('info').innerHTML += "[" + errorCnt + "] status=" + status + " successCnt=" + successCnt + "<br>";
                errorCnt += 1;
