Question

我正在请求Google地方信息数据，其中填入了“ fields”参数，例如Google：https://developers.google.com/places/web-service/details#fields 我只要求3个字段：geometry, name, vicinity。

在文档中明确指出您应至少提供1个字段：https://developers.google.com/places/web-service/details#fields

function requestGooglePlaces(placeType) {
    var request = {
        fields: ['name', 'geometry', 'vicinity'],
        location: location,
        radius: '5000',
        type: [placeType],
    };

    service = new google.maps.places.PlacesService(map);
    service.nearbySearch(request, callback);
}

function callback(results, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) {
        for (var i = 0; i < results.length; i++) {
            createMarker(results[i]);
        }
    }
}

function createMarker(place) {
    var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location,
    });

    google.maps.event.addListener(marker, 'click', function () {
        console.log(place);
        var contentInfoWindows = (place.name + "<br>" + place.vicinity + "<br>" + place.geometry.location);

    });

在我的Javascript输出控制台中，我收到了太多字段：

Answer 1

Nearby Search Request没有fields参数。

您引用的文档是针对 Place Details Requests 的，而不是您提供的代码中使用的文档。

Usage & Billing页面还指定：

“附近搜索”请求返回具有完整地点详细信息的地点列表（“附近搜索”请求不支持指定返回的字段）。

Google Places API字段过滤器不适用
