java http加上账号密码发送xml报文

在Java中，你可以使用HttpURLConnection类来发送HTTP请求，并且可以附加账号密码进行身份验证。以下是一个示例代码，展示如何使用Java的HttpURLConnection类发送XML报文并附加账号密码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
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 HttpXmlSender {
    public static void main(String[] args) {
        // 设置账号密码
        String username = "your_username";
        String password = "your_password";

        // 构建XML报文
        String xml = "<xml>...</xml>";

        // 设置请求地址
        String url = "http://example.com/api";

        try {
            // 创建URL对象
            URL apiUrl = new URL(url);
            // 打开连接
            HttpURLConnection connection = (HttpURLConnection) apiUrl.openConnection();
            // 设置请求方法
            connection.setRequestMethod("POST");

            // 添加账号密码的身份验证
            String authString = username + ":" + password;
            String encodedAuthString = Base64.getEncoder().encodeToString(authString.getBytes(StandardCharsets.UTF_8));
            String authHeader = "Basic " + encodedAuthString;
            connection.setRequestProperty("Authorization", authHeader);

            // 设置请求头部属性
            connection.setRequestProperty("Content-Type", "application/xml");

            // 允许输出数据
            connection.setDoOutput(true);

            // 发送请求数据
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(xml.getBytes(StandardCharsets.UTF_8));
            outputStream.flush();
            outputStream.close();

            // 获取响应
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 读取响应数据
                InputStream inputStream = connection.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8));
                String line;
                StringBuilder response = new StringBuilder();
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();
                inputStream.close();

                // 处理响应数据
                System.out.println("Response: " + response.toString());
            }

            // 断开连接
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
