Java HTTP客户端库：使用 HttpClient 进行网络请求

HttpClient是Java标准库中的一个部分，它提供了一种高级接口来向HTTP服务器发送请求并接收响应。

以下是一个简单的示例，展示如何使用HttpClient发送GET请求：

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.util.EntityUtils;
public class HttpClientExample {
    public static void main(String[] args) throws Exception {
        // 创建HttpClient实例
        CloseableHttpClient httpclient = HttpClients.createDefault();
        try {
            // 发送GET请求
            HttpGet httpget = new HttpGet("http://example.com");
            CloseableHttpResponse response = httpclient.execute(httpget);
            // 读取响应实体
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                System.out.println("Response Content: " + EntityUtils.toString(entity, "utf-8")));
            }
        } finally {
            // 关闭HttpClient，释放资源
            httpclient.close();
        }
    }
}
