如何通过在接口中封装HttpClient来模拟HttpClient

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 HttpClientExample {
    public static void main(String[] args) {
        // 创建HttpClient实例
        HttpClient httpClient = HttpClientBuilder.create().build();

        // 创建HttpGet请求
        HttpGet httpGet = new HttpGet("http://example.com/api");

        try {
            // 执行请求并获取响应
            HttpResponse response = httpClient.execute(httpGet);

            // 获取响应体
            HttpEntity entity = response.getEntity();
            String responseBody = EntityUtils.toString(entity);

            // 处理响应结果
            System.out.println(responseBody);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
