“附近搜索（新）”可采用一个或多个地点类型，并返回匹配的地点的列表。
“附近搜索（新）”可以根据指定的地点类型（例如 restaurant、book_store 或 bowling_alley）返回一组地点的相关信息。该服务会返回指定 locationRestriction 半径内与指定的地点类型相匹配的地点列表。
若要使用“附近搜索（新）”，您必须在 Google Cloud 项目中启用“Places API（新）”。如需了解详情，请参阅开始使用。
查找附近的地点
调用 searchNearby 即可根据指定的地点类型、位置或半径返回地点列表。请使用请求指定搜索参数，然后调用 searchNearby。返回的结果将会是一个 Place 对象列表，您可以从中获取地点详情。以下代码段显示了一个请求和 searchNearby 调用示例：
TypeScript
// Restrict within the map viewport.
let center = new google.maps.LatLng(52.369358, 4.889258);
const request = {
// required parameters
fields: ['displayName', 'location', 'businessStatus'],
locationRestriction: {
center: center,
radius: 500,
},
// optional parameters
includedPrimaryTypes: ['restaurant'],
maxResultCount: 5,
rankPreference: SearchNearbyRankPreference.POPULARITY,
language: 'en-US',
region: 'us',
};
//@ts-ignore
const { places } = await Place.searchNearby(request);
JavaScript
// Restrict within the map viewport.
let center = new google.maps.LatLng(52.369358, 4.889258);
const request = {
// required parameters
fields: ["displayName", "location", "businessStatus"],
locationRestriction: {
center: center,
radius: 500,
},
// optional parameters
includedPrimaryTypes: ["restaurant"],
maxResultCount: 5,
rankPreference: SearchNearbyRankPreference.POPULARITY,
language: "en-US",
region: "us",
};
//@ts-ignore
const { places } = await Place.searchNearby(request);
fields参数（必需）用于指定一个逗号分隔列表，其中包含一个或多个数据字段。locationRestriction参数（必需）用于指定一个最大 50,000 米的半径。includedPrimaryTypes参数用于指定要搜索的一个或多个地点类型。rankPreference参数用于指定POPULARITY或DISTANCE的SearchNearbyRankPreference。- 查看完整的参数列表。
示例
以下示例使用 searchNearby 来查询中心半径 500 米范围内的餐厅，并在地图中填充标记来显示结果。
