要实现高德搜索并返回搜索信息,可以使用高德地图API提供的Web服务。以下是Java代码示例:
首先,引入以下依赖包:
```xml
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.62</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.12</version>
</dependency>
```
然后,编写Java代码:
```java
import com.alibaba.fastjson.JSON;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.net.URLEncoder;
public class AmapSearch {
public static void main(String[] args) throws IOException {
String keyword = "北京大学";
String city = "北京";
String url = "https://restapi.amap.com/v3/place/text?keywords=" + URLEncoder.encode(keyword, "UTF-8") +
"&city=" + URLEncoder.encode(city, "UTF-8") + "&output=json&key=您的高德地图API Key";
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);
HttpResponse response = httpclient.execute(httpGet);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity, "UTF-8");
AmapSearchResult searchResult = JSON.parseObject(result, AmapSearchResult.class);
if (searchResult.getStatus().equals("1")) {
for (AmapPoi poi : searchResult.getPois()) {
System.out.println(poi.getName() + " " + poi.getAddress());
}
} else {
System.out.println("搜索失败");
}
}
}
class AmapSearchResult {
private String status;
private String count;
private String info;
private String infocode;
private AmapPoi[] pois;
// getters and setters
}
class AmapPoi {
private String name;
private String address;
private String location;
private String pname;
private String cityname;
private String adname;
// getters and setters
}
```
在上面的代码中,我们使用了HTTP客户端库Apache HttpComponents来发送HTTP请求,使用Fastjson库来解析JSON数据。使用高德地图Web服务API时,需要替换代码中的“您的高德地图API Key”为自己的API Key。可以在高德开放平台上注册并申请API Key。
