  嘿男人好像你正在使用自己的服务器但是你需要在php端使用你的活盐和商家密钥才看看这个解决方案https://stackoverflow.com/a/32500376/3514144

  您没有使用 Salt & key 从服务器生成 hash

  在服务器端生成哈希的示例代码：

  <?php
  
  function getHashes($txnid, $amount, $productinfo, $firstname, $email, $user_credentials, $udf1, $udf2, $udf3, $udf4, $udf5,$offerKey,$cardBin)
  {
        // $firstname, $email can be "", i.e empty string if needed. Same should be sent to PayU server (in request params) also.
        $key = 'gtKFFx';
        $salt = 'eCwWELxi';
  
        $payhash_str = $key . '|' . checkNull($txnid) . '|' .checkNull($amount)  . '|' .checkNull($productinfo)  . '|' . checkNull($firstname) . '|' . checkNull($email) . '|' . checkNull($udf1) . '|' . checkNull($udf2) . '|' . checkNull($udf3) . '|' . checkNull($udf4) . '|' . checkNull($udf5) . '||||||' . $salt;
        $paymentHash = strtolower(hash('sha512', $payhash_str));
        $arr['payment_hash'] = $paymentHash;
  
        $cmnNameMerchantCodes = 'get_merchant_ibibo_codes';
        $merchantCodesHash_str = $key . '|' . $cmnNameMerchantCodes . '|default|' . $salt ;
        $merchantCodesHash = strtolower(hash('sha512', $merchantCodesHash_str));
        $arr['get_merchant_ibibo_codes_hash'] = $merchantCodesHash;
  
        $cmnMobileSdk = 'vas_for_mobile_sdk';

  以下是java中pay u集成的哈希生成：
