调用高德地图，通过获取的区域名称得到行政区域详情

此工具为本人项目中所用，拿来即用，可使用postman接口调试工具来测试：

一、pom文件：

4.0.0

二、HttpClientUtil工具类
package com.java.gaode;
/**

/**

  @Controller
  public class HttpClientUtil {

  private static final Logger logger = LoggerFactory.getLogger(HttpClientUtil.class);

    public static String doGet(String url, Map params) {
    if (!StringUtils.hasText(url)) {
    return “”;
    }
    HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
    CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
    try {
    if (params != null && !params.isEmpty()) {
    List pairs = new ArrayList(params.size());
    for (String key : params.keySet()) {
    pairs.add(new BasicNameValuePair(key, params.get(key).toString()));
    }
    url += “?” + EntityUtils.toString(new UrlEncodedFormEntity(pairs, “UTF-8”));
    }
    HttpGet httpGet = new HttpGet(url);
    CloseableHttpResponse response = closeableHttpClient.execute(httpGet);
    HttpEntity entity = response.getEntity();
    // 判断响应实体是否为空
    if (entity != null) {
    return EntityUtils.toString(entity, “UTF-8”);
    } else {
    return null;
    }
    } catch (Exception e) {
    e.printStackTrace();
    } finally {
    try {
    // 关闭流并释放资源
    closeableHttpClient.close();
    } catch (IOException e) {
    logger.error(e.toString());
    }
    }
    return null;
    }

  /**

  • @Description 发送post请求（带参数）

  • @author HeLiu

  • @date 2018/11/16 11:02
    */
    public static Map doPost(String url, Map param) {
    try {
    Client client = Client.create();
    URI u = new URI(url);
    WebResource resource = client.resource(u);
    MultivaluedMap params = new MultivaluedMapImpl();

     Iterator i$ = param.entrySet().iterator();while (i$.hasNext()) {Map.Entry> e = (Map.Entry) i$.next();params.add(e.getKey(), String.valueOf(e.getValue()));}logger.info("查询参数:" + params.toString());String result = resource.type(MediaType.APPLICATION_FORM_URLENCODED).post(String.class, params);logger.info("url = :{},返回结果：{}", url, result);JSONObject jasonObject = JSONObject.parseObject(result);return (Map) jasonObject;
    

    } catch (Exception e) {
    logger.error("…", e);
    }
    return null;
    }

}

三、测试

package com.java.gaode;

import com.alibaba.fastjson.JSONObject;

import java.util.HashMap;
import java.util.Map;

/**

• @ClassName: GaoTest

• @Description:

• @Version: v1.0.0

• @Author: Fu Hao

• @Date: 2019/10/22 0022 下午 9:30

• Modification History:

• Date Author Version Description

• 2019/10/22 0022 *** v1.0.0 创建
  */
  public class GaoTest {
  public static void main(String[] args) {
  String keyName = “中国”;//这里是key名称
  String keyCode = “高德官网申请”;//这个是秘钥
  String admAddress = “https://restapi.amap.com/v3/config/district”;
  Map params = new HashMap<>();

   params.put("key", keyCode);params.put("keywords", keyName);params.put("subdistrict", 1);params.put("extensions", "base");String result = HttpClientUtil.doGet(admAddress, params);System.out.println(JSONObject.parse(result));
  

  }
  }

本人因为工作繁忙，每周都会抽一次时间，把自己在项目中使用的技术更加分享，志同道合的朋友可以加我扣扣，863967089，备注博客。
