Java网络编程：HTTP请求响应实例

在Java中，我们可以使用Apache HttpClient库来发送HTTP请求并接收响应。以下是一个简单的HTTP GET请求响应的实例：

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;
public class HttpRequestExample {
    public static void main(String[] args) {
        // 创建HttpClient实例
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try {
            // 创建HttpGet请求对象
            HttpGet httpGet = new HttpGet("http://example.com/api/data"); // 替换为实际URL
            // 执行HTTP请求，获取响应
            HttpResponse response = httpClient.execute(httpGet);
            if (response.getStatusLine().getStatusCode() == 200) {
                System.out.println("Response received successfully:");
                System.out.println(response.toString());
            } else {
                System.out.println("Failed to receive response. Status code: " + response.getStatusLine().getStatusCode());
            }
        } finally {
            // 关闭HttpClient连接
            httpClient.close();
        }
    }
}
