自动完成谷歌地址api

Question

我正在使用 google 自动完成地址 api，它返回所有必需的数据，但不返回邮政编码。知道如何在 api 响应中获取邮政编码。下面是这个 api 返回的我的 url 和 api 响应。

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=19becket st  &types=address&key=my_api_key

数据返回格式如下

{
            "description": "19 Becket St, Boston, MA, USA",
            "matched_substrings": [
                {
                    "length": 2,
                    "offset": 0
                },
                {
                    "length": 9,
                    "offset": 3
                }
            ],
            "place_id": "ChIJN9v2H4l744kRRg9DI6ctGhY",
            "reference": "ChIJN9v2H4l744kRRg9DI6ctGhY",
            "structured_formatting": {
                "main_text": "19 Becket St",
                "main_text_matched_substrings": [
                    {
                        "length": 2,
                        "offset": 0
                    },
                    {
                        "length": 9,
                        "offset": 3
                    }
                ],
                "secondary_text": "Boston, MA, USA"
            },
            "terms": [
                {
                    "offset": 0,
                    "value": "19"
                },
                {
                    "offset": 3,
                    "value": "Becket St"
                },
                {
                    "offset": 14,
                    "value": "Boston"
                },
                {
                    "offset": 22,
                    "value": "MA"
                },
                {
                    "offset": 26,
                    "value": "USA"
                }
            ],
            "types": [
                "premise",
                "geocode"
            ]
        },

Answer 1

使用place_id 对place details 进行后续请求。

• 对自动完成请求和详细信息请求使用相同的 session token
• 在详细信息请求中使用fields parameter

https://maps.googleapis.com/maps/api/place/details/json
  ?fields=address_components
  &place_id=ChIJN9v2H4l744kRRg9DI6ctGhY
  &key=YOUR_API_KEY

邮政编码将位于响应的address_components 字段中，类型为postal_code，类似于以下内容：

{
address_components":
        [
          { "long_name": "48", "short_name": "48", "types": ["street_number"] },
          {
            "long_name": "Pirrama Road",
            "short_name": "Pirrama Rd",
            "types": ["route"],
          },
          {
            "long_name": "Pyrmont",
            "short_name": "Pyrmont",
            "types": ["locality", "political"],
          },
          {
            "long_name": "Council of the City of Sydney",
            "short_name": "Sydney",
            "types": ["administrative_area_level_2", "political"],
          },
          {
            "long_name": "New South Wales",
            "short_name": "NSW",
            "types": ["administrative_area_level_1", "political"],
          },
          {
            "long_name": "Australia",
            "short_name": "AU",
            "types": ["country", "political"],
          },
          {
            "long_name": "2009",
            "short_name": "2009",
            "types": ["postal_code"],
          },
        ],
}
