根据您的偏好保存内容并对其进行分类。
Geolocation API 是一项服务，可接受包含移动客户端可检测到的手机基站和 Wi-Fi 接入点的 HTTPS 请求。对于每个有效输入，它都会返回纬度/经度坐标和一个半径，用于指示结果的准确性。
为何要使用 Geolocation API
使用 Geolocation API 定位不提供原生地理定位功能的移动设备。
您可以利用 Geolocation API 执行的操作
借助 Geolocation API，您可以使用来自手机基站和 Wi-Fi 节点的地理空间数据来获取没有原生地理定位或 GPS 的设备的位置信息。
Geolocation API 的工作方式
Geolocation API 使用移动设备数据字段、手机基站数据和 Wi-Fi 接入点阵列数据来返回纬度/经度坐标和准确度半径。它接受发送到其端点的 HTTPS POST 请求以及 JSON 结构化请求正文。以下示例展示了请求网址和请求正文示例：
curl -X POST "https://www.googleapis.com/geolocation/v1/geolocate?key=YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d \
'{ "homeMobileCountryCode":310,
"homeMobileNetworkCode":410,
"radioType":"gsm",
"carrier":"Vodafone",
"considerIp":true
}'
API 可以返回许多常见移动网络数据字段的数据，如下所示。

For more information, go to [Geolocation:\n| Displaying User or Device Position on Maps](/maps/documentation/javascript/geolocation).\n| - **Mobile devices geolocation** : Go to [Geocoding API](/maps/documentation/geocoding/overview).\n|\n| For more information on the W3C Geolocation standard, see\n| [W3C Geolocation standard](https://w3c.github.io/geolocation-api/).\n\nWhat you can do with the Geolocation API\n\nWith the Geolocation API, you can use geospatial data from cell towers\nand WiFi nodes to get the location of a device that does not have native geolocation or GPS.\n\nHow the Geolocation API works\n\nThe Geolocation API uses cellular device data fields, cell tower\ndata, and WiFi access point array data to return latitude/longitude coordinates and an accuracy\nradius. It accepts an HTTPS POST request to its endpoint along with a JSON structured request\nbody. The following example shows the request URL and an example request body:\n\n```json\ncurl -X POST \"https://www.googleapis.com/geolocation/v1/geolocate?key=\u003cvar translate=\"no\"\u003eYOUR_API_KEY\u003c/var\u003e\" \\\n-H \"Content-Type: application/json\" \\\n-d \\\n'{ \"homeMobileCountryCode\":310,\n \"homeMobileNetworkCode\":410,\n \"radioType\":\"gsm\",\n \"carrier\":\"Vodafone\",\n \"considerIp\":true\n}'\n```\nThe API can return data for a number of common cellular data fields as indicated below.\n\nResources\n\nThe following table summarizes the fields in the request body of the geolocation endpoint\ncall, along with the type of data provided from such queries.\n\n| Data resources | Data returned | Return format |\n|----------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------|---------------|\n| [Cell device data fields](/maps/documentation/geolocation/requests-geolocation#body) such as carrier, device, and network information. | Latitude/longitude coordinates and an accuracy radius | JSON |\n| [Cell tower data](/maps/documentation/geolocation/requests-geolocation#cell_tower_object), such as location area code and mobile country codes. | Latitude/longitude coordinates and an accuracy radius | JSON |\n| [WiFi access points data](/maps/documentation/geolocation/requests-geolocation#wifi_access_point_object), such as MAC address and signal strength. | Latitude/longitude coordinates and an accuracy radius | JSON |\n\nHow to use the Geolocation API\n\n|---|------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| 1 | **Get set up** | Start with [Set up your Google Cloud project](/maps/documentation/elevation/cloud-setup) and complete the setup instructions that follow. |\n| 2 | **Try a geolocation request** | Once you have an API key, you can start testing out the Geolocation API using cURL or Postman.
