I am trying to accept payments via PAYU in my android app, but I dont have a server and so I used firebase to store the data. From the video https://youtu.be/gnQ0IF3XniM I managed to integrate PAYU payment gateway from the server that is mentioned in the video. my code for generating the hash from server is as bellow :
@Override
protected PayuHashes doInBackground(String... postParams) {
PayuHashes payuHashes = new PayuHashes();
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");
// get the payuConfig first
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) {
case "payment_hash":
payuHashes.setPaymentHash(response.getString(key));
break;
case "vas_for_mobile_sdk_hash":
payuHashes.setVasForMobileSdkHash(response.getString(key));
break;
case "payment_related_details_for_mobile_sdk_hash":
payuHashes.setPaymentRelatedDetailsForMobileSdkHash(response.getString(key));
break;
case "delete_user_card_hash":
payuHashes.setDeleteCardHash(response.getString(key));
break;
case "get_user_cards_hash":
payuHashes.setStoredCardsHash(response.getString(key));
break;
case "edit_user_card_hash":
payuHashes.setEditCardHash(response.getString(key));
break;
case "save_user_card_hash":
payuHashes.setSaveCardHash(response.getString(key));
break;
case "check_offer_status_hash":
payuHashes.setCheckOfferStatusHash(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 payuHashes;
}
@Override
protected void onPostExecute(PayuHashes payuHashes) {
super.onPostExecute(payuHashes);
progressDialog.dismiss();
launchSdkUI(payuHashes);
}
}
Can anyone tell me how to generate hash from firebase server and integrate PAYU payment gateway.
