哪里是一个好的地址解析器

我正在寻找一个好的工具,可以采用完整的邮件地址,格式化显示或与邮件标签一起使用,并将其转换为结构化对象.

例如:

// Start with a formatted address in a single string
string f = "18698 E. Main Street\r\nBig Town, AZ, 86011";

// Parse into address
Address addr = new Address(f);

addr.Street; // 18698 E. Main Street
addr.Locality; // Big Town
addr.Region; // AZ
addr.PostalCode; // 86011

现在我可以使用RegEx来做到这一点.但棘手的部分是保持它足够通用,以处理世界上的任何地址!

我确信必须有一些可以做到的东西.

如果有人注意到,这实际上是opensocial.address对象的格式.

Googlemaps API非常适用于此.例如,假设您被给予字符串"120 w 45 st nyc".将其传递到Googlemaps API,如下所示:http://maps.google.com/maps/geo?q=120+w+45+st+nyc您会得到以下回复:

{
  "name": "120 w 45 st nyc",
  "Status": {
    "code": 200,
    "request": "geocode"
  },
  "Placemark": [ {
    "id": "p1",
    "address": "120 W 45th St, New York, NY 10036, USA",
    "AddressDetails": {"Country": {"CountryNameCode": "US","CountryName": "USA","AdministrativeArea": {"AdministrativeAreaName": "NY","Locality": {"LocalityName": "New York","Thoroughfare":{"ThoroughfareName": "120 W 45th St"},"PostalCode": {"PostalCodeNumber": "10036"}}}},"Accuracy": 8},
    "ExtendedData": {
      "LatLonBox": {
        "north": 40.7603883,
        "south": 40.7540931,
        "east": -73.9807141,
        "west": -73.9870093
      }
    },
    "Point": {
      "coordinates": [ -73.9838617, 40.7572407, 0 ]
    }
  } ]
}

我想我想知道Google是如何做到的.

每天限制约15,000个请求.所以要尊重并小心并检查使用条款http://econym.org.uk/gmap/geomulti.htm

这适用于已关闭的旧API v2.有关v3,请参阅https://developers.google.com/maps/documentation/geocoding/.免费api现在限制为每天2500.
