如何使用筛选条件进行地理编码

地理编码 API 允许您使用筛选条件获取所需结果。

潜在用途

使用筛选条件，根据您的业务需求来限制结果。

示例

为 IncludeCountries 指定一个值，以在结果中返回该国家/地区的值。

Sample request

如果不使用 IncludeCountries": ["USA"]，地理编码 API 将返回加拿大不列颠哥伦比亚省温哥华市。

{
  "QueryText": "Vancouver",
    "Filter" : {
        "IncludeCountries": ["USA"]
    }
}
Sample response
{
    "ResultItems": [
        {
            "PlaceId": "<Redacted>",
            "PlaceType": "Locality",
            "Title": "Vancouver, WA, United States",
            "Address": {
                "Label": "Vancouver, WA, United States",
                "Country": {
                    "Code2": "US",
                    "Code3": "USA",
                    "Name": "United States"
                },
                "Region": {
                    "Code": "WA",
                    "Name": "Washington"
                },
                "SubRegion": {
                    "Name": "Clark"
                },
                "Locality": "Vancouver",
                "PostalCode": "98660"
            },
            "Position": [
                -122.67156,
                45.63248
            ],
            "MapView": [
                -122.77466,
                45.57714,
                -122.46451,
                45.69803
            ],
            "MatchScores": {
                "Overall": 1,
                "Components": {
                    "Address": {
                        "Locality": 1
                    }
                }
            }
        }
    ]
}
cURL
curl --request POST \
  --url 'https://places.geo.eu-central-1.amazonaws.com/v2/geocode?key=Your_Key' \
  --header 'Content-Type: application/json' \
  --data '{
  "QueryText": "Vancouver",
    "Filter" : {
        "IncludeCountries": ["USA"]
    }
}'
AWS CLI
aws geo-places geocode --key ${YourKey} --query-text "Vancouver" --filter '{"IncludeCountries": ["USA"]}'

为 IncludePlaceTypes 指定一个值，以在结果中返回该地点的值。

Sample request

如果不使用 IncludePlaceTypes": ["Street"]，地理编码 API 将返回格鲁吉亚（一个国家）。您可以通过在 "IncludeCountries" 中添加 CAN 和 USA 的值来进一步优化结果，并将结果进行比较。

{
  "QueryText": "Georgia",
    "Filter" : {
        "IncludePlaceTypes": ["Street"]
    }

}
Sample response
{
    "ResultItems": [
        {
            "PlaceId": "<Redacted>",
            "PlaceType": "Street",
            "Title": "Georgia, Benito Juárez, CDMX, México",
            "Address": {
                "Label": "Georgia, Benito Juárez, CDMX, México",
                "Country": {
                    "Code2": "MX",
                    "Code3": "MEX",
                    "Name": "México"

                },

                "Street": "Georgia",
                "StreetComponents": [
                    {
                        "BaseName": "Georgia",
                        "Language": "es"
                    }
                ]
            },

开发人员提示

对于地址地理编码，请尽量使用完整的地址，或使用带有偏差位置组合（包括国家/地区和地点）的查询组件。要了解更多信息，请参阅如何对地址进行地理编码。
