Java，已知url和请求体id，key，对请求体进行aes加密，有aesutil工具，发送post请求获取数据的代码怎么写

在Java中，你可以使用`AESUtil`工具类配合`HttpURLConnection`或者第三方库如`OkHttp`或`Apache HttpClient`来进行AES加密的POST请求。这里提供一个基本的例子，假设`AESUtil`已经实现了AES加解密功能：

import javax.crypto.Cipher;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class AESPostRequestExample {

    private static final String URL = "http://example.com/api";
    private static final String REQUEST_ID = "request_id";
    private static final String KEY = "your_secret_key";

    // 假设AESUtil有这样的方法来加密和解密
    private static String encrypt(String data, String key) {
        try {
            Cipher cipher = Cipher.getInstance("AES");
            cipher.init(Cipher.ENCRYPT_MODE, getSecretKeySpec(key));
            byte[] encryptedBytes = cipher.doFinal(data.getBytes(StandardCharsets.UTF_8));
            return Base64.getEncoder().encodeToString(encryptedBytes);
        } catch (Exception e) {
            throw new RuntimeException("Error while encrypting", e);
        }
    }

    private static SecretKeySpec getSecretKeySpec(String key) throws NoSuchAlgorithmException {
        return new SecretKeySpec(key.getBytes(), "AES");
    }

    private static String decrypt(String encryptedData, String key) {
        // 类似于encrypt()方法，只是换成Cipher.DECRYPT_MODE
        // 这里省略了具体实现
    }

    public static void main(String[] args) {
        String requestBody = "YourRequestBody"; // 需要加密的原始请求体
        String encryptedRequestBody = encrypt(requestBody, KEY);

        // 创建HTTP POST请求
        HttpURLConnection connection = null;
        try {
            connection = (HttpURLConnection) new URL(URL).openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
            connection.setRequestProperty("X-Request-ID", REQUEST_ID);
            connection.setRequestProperty("Authorization", "Bearer " + encryptedRequestBody); // 假设这是一个基础的Bearer Token

            // 发送请求并获取响应
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 如果成功，从服务器获取响应，并解密它（这一步在这里省略）
                // response = decrypt(connection.getInputStream().readAllBytes(), KEY);
            } else {
                System.out.println("Error: " + responseCode);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (connection != null) {
                connection.disconnect();
            }
        }
    }
}
