微信请求头已添加Wechatpay-Serial，加密方法是从官方粘贴的：try {

    Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA-1AndMGF1Padding");

    cipher.init(Cipher.ENCRYPT_MODE, certificate.getPublicKey());

    byte[] data = message.getBytes("utf-8");

    byte[] cipherdata = cipher.doFinal(data);

    return Base64.getEncoder().encodeToString(cipherdata);

}

catch (Exception e) {

    log.error("", e);

    return null;

}，加密公钥使用的微信平台证书。接口调用报错：wechat pay server error, Request-ID 08B3ABD3B00610B80118A6FDCBF50120956928E0E201-269546542 , statusCode 400 BAD_REQUEST,result : {\"code\":\"PARAM_ERROR\",\"message\":\"平台私钥解密失败\"}。
