result:

{"code":0,"data":{"country":"中国","country_id":"CN","area":"华南","area_id":"800000","region":"广东省","region_id":"440000","city":"广州市","city_id":"440100","county":"越秀区","county_id":"440104","isp":"电信","isp_id":"100017","ip":"219.136.134.157"}}  
Country: China  
Region: South China  
Province: Guangdong Province  
City: Guangzhou  
District / County: Yuexiu District  
Internet Service Provider: Telecom  
China /Guangdong Province/Guangzhou City/Yuexiu District  

 However, when using Taobao's API, it is really slow, and a small amount of data is ok. Once the data exceeds 10,000, it will not end, and it will not end after waiting for a long time.

No way, start trying other methods.

 

Use the [GeoLite2 City] library (source: Java obtains the IP address corresponding to the province and city through the Request request )

 pom.xml:

<dependency>
            <groupId>com.maxmind.geoip2</groupId>
            <artifactId>geoip2</artifactId>
            <version>2.8.1</version>
        </dependency>

test:

public  static  void main(String[] args) throws IOException{      
       // Create GeoLite2 database      
      File database = new File("/Users/admin/GeoLite2-City.mmdb" );     
       // Read database content    
      DatabaseReader reader = new DatabaseReader. Builder(database).build();       
      InetAddress ipAddress = InetAddress.getByName("171.108.233.157");     

      // Get the query result       
      CityResponse response = null ;
         try {
            response = reader.city(ipAddress);

      // Get country information 
      Country country = response.getCountry();
      System.out.println(country.getIsoCode());               // 'CN'
      System.out.println(country.getName());                  // 'China'
      System.out.println(country.getNames().get("zh-CN"));    // '中国'

      // Get province 
      Subdivision subdivision = response.getMostSpecificSubdivision();
      System.out.println(subdivision.getName());    // 'Guangxi Zhuangzu Zizhiqu' 
      System.out.println(subdivision.getIsoCode()); // '45' 
      System.out.println(subdivision.getNames(). get("zh-CN")); // 'Guangxi Zhuang Autonomous Region'

      // Get the city 
      City city = response.getCity();
      System.out.println(city.getName()); // 'Nanning'
      Postal postal = response.getPostal();
      System.out.println(postal.getCode()); // 'null'
      System.out.println(city.getNames().get("zh-CN")); // '南宁'
      Location location = response.getLocation();
      System.out.println(location.getLatitude());  // 22.8167
      System.out.println(location.getLongitude()); // 108.3167
        } catch (GeoIp2Exception e) {
            e.printStackTrace ();
        }     


}  

This is very fast, but can only get the city.
