附近搜索

“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 restaurantbook_storebowling_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 POPULARITYDISTANCESearchNearbyRankPreference
  • 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。

    map = new Map(document.getElementById('map') as HTMLElement, {
        center: center,
        zoom: 11,
