I'm getting city name from a 3rd party API. That API doesn't return normalized city name. For example, sometimes its San Francisco, sometime its San Francisco, CA, sometimes its San Francisco, USA. I dont need street address etc.. I just need to normalize the city name to be something uniform. I'm looking for a service that could help me with this requirement.

P.S:它不是移动应用程序，它的Web应用程序和位置都不来自浏览器.

P.S: Its not mobile app, its web app and the location doesn't come from the browser.

推荐答案

您可以使用Google Maps API获取规范化的地址:

You can use the Google Maps API to get normalized address:

1)从以下位置获取结果: https://maps.googleapis .com/maps/api/geocode/json?address = san_francisco

1) Get result from: https://maps.googleapis.com/maps/api/geocode/json?address=san_francisco

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "San Francisco",
               "short_name" : "SF",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Condado San Francisco",
               "short_name" : "Condado San Francisco",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "Estados Unidos",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            }
         ],
         "formatted_address" : "San Francisco, California, EE. UU.",
         "geometry" : {
            "bounds" : {
               "northeast" : {
                  "lat" : 37.9298239,
                  "lng" : -122.28178
               },
               "southwest" : {
                  "lat" : 37.6398299,
                  "lng" : -123.173825
               }
            },
            "location" : {
               "lat" : 37.7749295,
               "lng" : -122.4194155
            },
            "location_type" : "APPROXIMATE",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.812,
                  "lng" : -122.3482
               },
               "southwest" : {
                  "lat" : 37.70339999999999,
                  "lng" : -122.527
               }
            }
         },
         "place_id" : "ChIJIQBpAG2ahYAR_6128GcTUEo",
         "types" : [ "locality", "political" ]
      }
   ],
   "status" : "OK"
}

2)从$data['results'][0]['address_components'][0]['long_name']中提取城市名称.

2) Extract the city name from $data['results'][0]['address_components'][0]['long_name'].

您应该检查返回的内容是否包含描述的字段，并且$data['status']是确定".
