如题，按照官方的文档执行也是这样，所有参数都有了，包括APIv3秘钥，依然报错

调用的URL是：https://api.mch.weixin.qq.com/risk/getcertficates

代码：

private static String aesgcmDecrypt(String aad, String iv, String cipherText) throws Exception {
    final Cipher cipher = Cipher.getInstance(ALGORITHM, "SunJCE");
    SecretKeySpec key = new SecretKeySpec(AES_KEY.getBytes("UTF-8"), "AES");
    GCMParameterSpec spec = new GCMParameterSpec(TAG_LENGTH_BIT, iv.getBytes(), 0, iv.length());
    cipher.init(Cipher.DECRYPT_MODE, key, spec);
    cipher.updateAAD(aad.getBytes());
    return new String(cipher.doFinal(Base64.getDecoder().decode(cipherText)));
}
