HttpClient可以以多种方式发送GET请求,以下是其中的一种示例代码:

import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.client.HttpClient;import org.apache.http.client.methods.HttpGet;import org.apache.http.impl.client.HttpClientBuilder;import org.apache.http.util.EntityUtils;public class HttpClientGetExample {public static void main(String[] args) {HttpClient httpClient = HttpClientBuilder.create().build();String url = "https://example.com/api";try {HttpGet request = new HttpGet(url);HttpResponse response = httpClient.execute(request);HttpEntity entity = response.getEntity();if (entity != null) {String result = EntityUtils.toString(entity);System.out.println(result);}} catch (Exception e) {e.printStackTrace();}}}

在这个示例中,我们首先创建了一个HttpClient实例,然后构造了一个HttpGet请求,并指定了请求的URL。然后使用httpClient.execute(request)方法发送GET请求,并获取响应。最后,通过EntityUtils.toString(entity)方法将响应的内容转换为字符串并进行输出。

需要注意的是,在使用HttpClient发送GET请求之前,需要确保你的项目中已经引入了HttpClient的相关依赖。
