成功生成 Hashkey 后，payUmoney 集成中出现一些错误消息

Question

我正在尝试集成 payUmoney 的支付网关。我正在关注 this method 哈希密钥已成功生成，但我仍然无法使用实时凭据进入支付页面。我正在使用此代码生成 HashKey--

当我使用这种方法发送从上面的代码生成的散列键时：

  private class GetHashesFromServerTask extends AsyncTask<String, String, String> {
    private ProgressDialog progressDialog;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        progressDialog = new ProgressDialog(MainActivity.this);
        progressDialog.setMessage("Please wait...");
        progressDialog.show();
    }

    @Override
    protected String doInBackground(String... postParams) {

        String merchantHash = "";
        try {
            //TODO Below url is just for testing purpose, merchant needs to replace this with their server side hash generation url
            URL url = new URL("https://payu.herokuapp.com/get_hash");

            String postParam = postParams[0];

            byte[] postParamsByte = postParam.getBytes("UTF-8");

            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            conn.setRequestProperty("Content-Length", String.valueOf(postParamsByte.length));
            conn.setDoOutput(true);
            conn.getOutputStream().write(postParamsByte);

            InputStream responseInputStream = conn.getInputStream();
            StringBuffer responseStringBuffer = new StringBuffer();
            byte[] byteContainer = new byte[1024];
            for (int i; (i = responseInputStream.read(byteContainer)) != -1; ) {
                responseStringBuffer.append(new String(byteContainer, 0, i));
            }

            JSONObject response = new JSONObject(responseStringBuffer.toString());

            Iterator<String> payuHashIterator = response.keys();
            while (payuHashIterator.hasNext()) {
                String key = payuHashIterator.next();
                switch (key) {
                    /**
                     * This hash is mandatory and needs to be generated from merchant's server side

                    case "payment_hash":
                        merchantHash = response.getString(key);
                        break;
                    default:
                        break;
                }
            }

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (ProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return merchantHash;
    }

    @Override
    protected void onPostExecute(String merchantHash) {
        super.onPostExecute(merchantHash);

        progressDialog.dismiss();
        payNowButton.setEnabled(true);

        if (merchantHash.isEmpty() || merchantHash.equals("")) {
            Toast.makeText(MainActivity.this, "Could not generate hash", Toast.LENGTH_SHORT).show();
        } else {
            mPaymentParams.setMerchantHash(merchantHash);

            if (AppPreference.selectedTheme != -1) {
                PayUmoneyFlowManager.startPayUMoneyFlow(mPaymentParams, MainActivity.this, AppPreference.selectedTheme, mAppPreference.isOverrideResultScreen());
            } else {
                PayUmoneyFlowManager.startPayUMoneyFlow(mPaymentParams, MainActivity.this, R.style.AppTheme_default, mAppPreference.isOverrideResultScreen());
            }
        }
    }
}

代码是否可以生成哈希键
感谢 Andvance

Answer 1

确保发送到 payUmoney 网关的密钥与 PHP 脚本哈希生成

中定义的相同

例如：产品名称的关键字是productInfo确保每个字符都相同。

否则代码是完美的，这只是您可能弄错的地方

Answer 2

使用关键字 firstName 和 productInfo 生成散列并检查 udf 参数。

成功生成 Hashkey 后，payUmoney 集成中出现一些错误消息
