Java：如何发送XML请求

Java：如何发送XML请求？

java
StringBuilder xmlRequest = new StringBuilder();
xmlRequest.append("");
xmlRequest.append("John Doe");
xmlRequest.append("30");
xmlRequest.append("");

java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class XMLRequestSender {
    public static void main(String[] args) throws Exception {
        // 构建XML请求
        StringBuilder xmlRequest = new StringBuilder();
        xmlRequest.append("");
        xmlRequest.append("John Doe");
        xmlRequest.append("30");
        xmlRequest.append("");
        // 创建URL对象
        URL url = new URL("http://example.com/api");
        
        // 创建HttpURLConnection对象
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        
        // 设置请求方法为POST
        conn.setRequestMethod("POST");
        
        // 设置请求头信息
        conn.setRequestProperty("Content-Type", "application/xml");
        
        // 开启输出流，将XML请求发送到目标系统
        conn.setDoOutput(true);
        OutputStream outputStream = conn.getOutputStream();
        outputStream.write(xmlRequest.toString().getBytes());
        outputStream.flush();
        
        // 获取HTTP响应
        int responseCode = conn.getResponseCode();
        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        StringBuilder response = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            response.append(line);
        }
        reader.close();
        
        // 输出HTTP响应结果
        System.out.println("Response Code: " + responseCode);
        System.out.println("Response Body: " + response.toString());
        
        // 关闭连接
        conn.disconnect();
    }
