类(新)和 PlacesService
(旧)中使用的附近搜索之间的区别,并提供了一些代码段以供比较。
- 旧版
PlacesService
具有 nearbySearch()
方法,可让您根据关键字或类型搜索指定区域内的地点。
Place
类具有 searchNearby()
方法,可让您按地点类型搜索指定区域内的地点,并利用扩展的地点数据字段和地点类型选择,从而实现更高的灵活性。
下表列出了 Place
类和 PlacesService
之间在附近搜索方法方面的一些主要区别:
代码比较
本部分比较了附近搜索方法的代码,以说明 Places 服务与 Place 类之间的区别。以下代码段展示了在每个相应 API 上发出基于文本的搜索请求所需的代码。
附近搜索(旧版)
通过旧版“附近搜索”,您可以根据关键字或类型搜索指定区域内的地点。您无法使用地点数据字段来限制搜索,因此每个请求都会返回所有可用的字段。以下代码段展示了如何调用 nearbySearch()
来返回澳大利亚悉尼的餐厅信息。该请求是同步的,使用回调,并且包含对 PlacesServiceStatus
的必需条件检查。
let map;
let service;
function initMap() {
const sydney = new google.maps.LatLng(-33.867, 151.195);
map = new google.maps.Map(document.getElementById("map"), {
center: sydney,
zoom: 15,
});
const request = {
location: sydney,
radius: '500',
type: ['restaurant']
};
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]);
}
}
}
// Helper function to create markers.
function createMarker(place) {
if (!place.geometry || !place.geometry.location) return;
const marker = new google.maps.Marker({
map,
position: place.geometry.location,
title: place.name,
});
}

附近搜索(新)
新版附近搜索在以下方面改进了旧版:
- 能够指定要返回哪些地点数据字段。
- 使用 Promise 来实现异步操作。
- 无需检查
PlacesService
的状态;可以改用标准错误处理。
以下代码段展示了一个用于发出餐厅附近搜索请求的函数。此示例展示了如何使用 rankPreference
选项按热门程度对搜索结果进行排名(在之前的版本中,排名是使用 rankBy
选项指定的)。由于 searchNearby()
方法使用 await
运算符,因此只能在 async
函数内使用。
async function nearbySearch() {
// 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: google.maps.places.SearchNearbyRankPreference.POPULARITY,
language: "en-US",
region: "us",
};
const { places } = await google.maps.places.Place.searchNearby(request);
if (places.length) {
console.log(places);
// Create a new bounds, which will be extended with each result.
const bounds = new google.maps.LatLngBounds();
// Loop through and get all the results.
places.forEach((place) => {
const markerView = new google.maps.marker.AdvancedMarkerElement({
map,
position: place.location,
title: place.displayName,
});
bounds.extend(place.location);
console.log(place);
});
map.fitBounds(bounds);
} else {
console.log("No results");
}
}

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nThis page explains the differences between nearby search as used in the\n[`Place`](/maps/documentation/javascript/reference/place) class (new) and the\n[`PlacesService`](/maps/documentation/javascript/reference/places-service)\n(legacy), and provides some code snippets for comparison.\n\n- The legacy `PlacesService` has a `nearbySearch()` method, which lets you search for places within a specified area by keyword or type.\n- The `Place` class has a `searchNearby()` method which lets you search for places within a specified area by place type, utilizing an expanded selection of place data fields and place types for greater flexibility.\n\nThe following table lists some of the main differences in nearby search methods\nbetween the `Place` class and `PlacesService`:\n\n| [`PlacesService`](/maps/documentation/javascript/reference/places-service) (Legacy) | [`Place`](/maps/documentation/javascript/reference/place) (New) |\n|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [`nearbySearch()`](/maps/documentation/javascript/reference/places-service#PlacesService.nearbySearch) | [`searchNearby()`](/maps/documentation/javascript/reference/place#Place.searchNearby) |\n| [`PlaceSearchRequest`](/maps/documentation/javascript/reference/places-service#PlaceSearchRequest) | [`SearchNearbyRequest`](/maps/documentation/javascript/reference/place#SearchNearbyRequest) |\n| Requires the use of a callback to handle the results object and `google.maps.places.PlacesServiceStatus` response. | Uses Promises, and works asynchronously. |\n| Requires a `PlacesServiceStatus` check. | No required status check, can use standard error handling. [Learn more](/maps/documentation/javascript/reference/errors). |\n| Supports only location bias. | Supports location bias and location restriction. |\n| Returns all available data fields (a [subset of the supported fields](/maps/documentation/places/web-service/place-data-fields#places-api-fields-support)); cannot be constrained to specific fields. | Returns only the requested [place data fields](/maps/documentation/javascript/place-class-data-fields); the `Place` class offers an expanded and regularly updated selection of fields. |\n| Limited to a fixed set of [place types](/maps/documentation/javascript/supported_types). | Access an expanded and regularly updated selection of [place types](/maps/documentation/javascript/place-types). |\n| Supported text-based search with the [keyword](/maps/documentation/javascript/reference/places-service#PlaceSearchRequest.keyword). | Text-based search is not supported, use [Text Search (New)](/maps/documentation/javascript/places-migration-search#place-class-new) instead. |\n\nCode comparison\n---------------\n\nThis section compares code for nearby search methods to illustrate the\ndifferences between the Places Service and the\nPlace class. The code snippets show the code\nrequired on each respective API to make a text-based search request.\n\n### Nearby Search (Legacy)\n\nThe legacy Nearby Search lets you search for places within a specified area by\nkeyword or type. There is no way to constrain searches by using place data\nfields, so that all of the available fields are returned with each request.\nThe following snippet shows calling `nearbySearch()` to return information about\nrestaurants in Sydney, Australia. The request is synchronous, uses a callback,\nand includes a required conditional check on `PlacesServiceStatus`. \n\n let map;\n let service;\n\n function initMap() {\n const sydney = new google.maps.LatLng(-33.867, 151.195);\n\n map = new google.maps.Map(document.getElementById(\"map\"), {\n center: sydney,\n zoom: 15,\n });\n\n const request = {\n location: sydney,\n radius: '500',\n type: ['restaurant']\n };\n\n service = new google.maps.places.PlacesService(map);\n service.nearbySearch(request, callback);\n }\n\n function callback(results, status) {\n if (status == google.maps.places.PlacesServiceStatus.OK) {\n for (var i = 0; i \u003c results.length; i++) {\n createMarker(results[i]);\n }\n }\n }\n\n // Helper function to create markers.\n function createMarker(place) {\n if (!place.geometry || !place.geometry.location) return;\n\n const marker = new google.maps.Marker({\n map,\n position: place.geometry.location,\n title: place.name,\n });\n }\n\n#### Learn more\n\n- [See the documentation for legacy Nearby Search](/maps/documentation/javascript/places#place_search_requests)\n- [See the `searchNearby()` reference](/maps/documentation/javascript/reference/places-service#PlacesService.nearbySearch)\n\n### Nearby Search (New)\n\nThe new version of Nearby Search improves upon its predecessor in the following\nways:\n\n- The ability to specify which place data fields to return.\n- The use of Promises which enables asynchronous operation.\n- No need to check for the status of `PlacesService`; standard error handling can be used instead.\n\nThe following code snippet shows a function which makes a Nearby Search request\nfor restaurants. This example shows using the `rankPreference` option to rank\nsearch results by popularity (in the previous version ranking is specified\nusing the `rankBy` option). Because the `searchNearby()` method uses the `await`\noperator it can only be used inside an `async` function. \n\n async function nearbySearch() {\n // Restrict within the map viewport.\n let center = new google.maps.LatLng(52.369358, 4.889258);\n const request = {\n // Required parameters.\n fields: [\"displayName\", \"location\", \"businessStatus\"],\n locationRestriction: {\n center: center,\n radius: 500,\n },\n // Optional parameters.\n includedPrimaryTypes: [\"restaurant\"],\n maxResultCount: 5,\n rankPreference: google.maps.places.SearchNearbyRankPreference.POPULARITY,\n language: \"en-US\",\n region: \"us\",\n };\n\n const { places } = await google.maps.places.Place.searchNearby(request);\n\n if (places.length) {\n console.log(places);\n\n // Create a new bounds, which will be extended with each result.\n const bounds = new google.maps.LatLngBounds();\n\n // Loop through and get all the results.\n places.forEach((place) =\u003e {\n const markerView = new google.maps.marker.AdvancedMarkerElement({\n map,\n position: place.location,\n title: place.displayName,\n });\n\n bounds.extend(place.location);\n console.log(place);\n });\n map.fitBounds(bounds);\n } else {\n console.log(\"No results\");\n }\n }\n\n#### Learn more\n\n- [See the complete example code](/maps/documentation/javascript/examples/place-nearby-search)\n- [See the documentation for Nearby Search (New)](/maps/documentation/javascript/nearby-search)\n- [See the `searchNearby()` reference](/maps/documentation/javascript/reference/place#Place.searchNearby)"]]
