Java根据Ip获取地址详细信息

笔者这里使用的是ali的开放api 的url , 所以需要使用htttp 形式调用,

至于调用方式多种多样, 我这里挑一个就很简单的 Rest Template来使用

### 配置RestTemplate ###

import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.http.client.ClientHttpRequestFactory;
    import org.springframework.http.client.SimpleClientHttpRequestFactory;
    import org.springframework.web.client.RestTemplate;
    
    
    /**
     * @author huang
     */
    @Configuration
    public class RestTemplateConfig {
    
        @Bean
        public RestTemplate restTemplate(ClientHttpRequestFactory factory) {
            return new RestTemplate(factory);
        }
    
        @Bean
        public ClientHttpRequestFactory simpleClientHttpRequestFactory() {
            SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
            factory.setConnectTimeout(15000);
            factory.setReadTimeout(5000);
            return factory;
        }
    }

### Service封装 ###

注意这里面的各种类都没啥特殊的 , 如果缺少某些json类啥的都可以直接引入

import com.alibaba.fastjson.JSON;
    import com.alibaba.fastjson.JSONObject;
    import org.apache.commons.lang.StringUtils;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.http.ResponseEntity;
    import org.springframework.stereotype.Component;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @author huang
     */
    @Component
    public class AliService {
    
        private static final Logger log = LoggerFactory.getLogger(AliService.class);
    
        private static final String URL = "https://ip.taobao.com/outGetIpInfo?ip=IPaddress&&accessKey=alibaba-inc";
    
        @Autowired
        RestTemplate restTemplate;
    
        public JSONObject getAreaFromAli(String ip) {
            String url = StringUtils.replace(URL, "IPaddress", ip);
            String body = null;
            log.info("请求Ali获取ip地址所属地区,url:{}", url);
            try {
                ResponseEntity<String> forEntity = restTemplate.getForEntity(url, String.class);
                body = forEntity.getBody();
            } catch (Exception e) {
                log.error("请求Ali获取ip地址所属地区异常:" + e.getMessage(), e);
            }
            if (StringUtils.isBlank(body)) {
                log.error("请求Ali获取ip地址所属地区异常,返回为空");
                return null;
            }
            JSONObject res = JSON.parseObject(body, JSONObject.class);
            if (0 != res.getInteger("code")) {
                log.error("请求Ali根据ip获取地区信息失败，状态码：{}", res.getInteger("code"));
                return null;
            }
            return res.getJSONObject("data");
    
        }
    }
