基于Java的HTTP客户端编程示例

在Java中，我们可以使用HttpURLConnection或者HttpClient来编写HTTP客户端。以下是一个使用HttpURLConnection的简单示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import javax.net.ssl.HttpsURLConnection;
public class HttpClientExample {
    public static void main(String[] args) throws Exception {
        // 创建连接，这里我们使用https
        HttpsURLConnection urlConnection = (HttpsURLConnection) new URL("https://example.com").openConnection();
        // 设置请求方法，这里是GET
        urlConnection.setRequestMethod("GET");
        // 获取响应状态码
        int responseCode = urlConnection.getResponseCode();
        System.out.println("Response Code : " + responseCode);
        // 读取响应内容（这里我们使用BufferedReader）
        BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream())));
        String inputLine;
        StringBuffer content = new StringBuffer();
        while ((inputLine = in.readLine()) != null) {
            content.append(inputLine);
        }
        in.close();
        System.out.println("Response Content : " + content.toString());
    }
}
