echo "【你需要做的】\n";
echo "联系建行技术支持，询问:\n";
echo "1. A3341TP01接口的cnt字段应该用哪个公钥加密？\n";
echo "   - 商户自己的公钥？\n";
echo "   - 建行平台的公钥？（更合理）\n\n";
echo "2. 如果需要建行平台公钥，请建行提供\n\n";
echo "3. 确认你的商户公钥是否已在建行备案\n\n";

echo "【489错误的真正原因】\n";
echo "很可能是因为:\n";
echo "1. 用错了公钥加密（用商户公钥而不是建行平台公钥）\n";
echo "2. 建行服务器无法解密你的请求\n";
echo "3. 所以返回489系统异常\n\n";
