java http认证账号密码发送xml报文

在Java中发送带有HTTP认证的XML报文，你可以使用Java的URLConnection类来完成。以下是一个示例代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class HttpXmlRequest {
    public static void main(String[] args) {
        String username = "username";
        String password = "password";
        String xmlPayload = "<xml>...</xml>";
        String url = "http://example.com/api";

        try {
            // 创建URL对象
            URL apiUrl = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) apiUrl.openConnection();

            // 设置HTTP请求方法为POST
            connection.setRequestMethod("POST");
            
            // 设置HTTP Basic认证
            String auth = username + ":" + password;
            byte[] authBytes = auth.getBytes(StandardCharsets.UTF_8);
            String encodedAuth = Base64.getEncoder().encodeToString(authBytes);
            connection.setRequestProperty("Authorization", "Basic " + encodedAuth);

            // 设置请求头和请求体
            connection.setRequestProperty("Content-Type", "application/xml");
            connection.setDoOutput(true);
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(xmlPayload.getBytes());
            outputStream.flush();
            outputStream.close();

            // 发送请求并获取响应
            int responseCode = connection.getResponseCode();
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // 处理响应
            System.out.println("Response Code: " + responseCode);
            System.out.println("Response Body: " + response.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
