algo-pay-only-javascript
Work in progress project to port AlgoPay react to pure javascript
build command (to dist folder, will create if does not exist):
npm run buildto correctly show css after bulding, modify the index.html that is generated in the dist folder by:
- removing one of the
<link>tags for the css - removing the numeric hash from the remaining
<link>tag so that the href reads "styles.css" - renaming the js file to "index.js"
- renaming the
<script>tag src to "index.js"
Finally, copy your styles.css file into the dist folder.
Test build command on localhost:
serve -s dist
Algopay 2.1 Update: Add Post to custom URL (temp documentation for post)
in window details, add "backend_enable":false Script will work like always.
In window details, add "backend_enable":true,backend_url":"your_backend_url",backend_value1=your_value...." TXID and custom parameters will be sent by post to chosen URL
Example using pseudoPHP:
//Get the POST data $update = json_decode(file_get_contents("php://input"), TRUE); //Get the TXID $txid = $update["txid"]; //Get value 1, lets say we send customer email $email = $update["backend_value1"];
//Wait block for being processed sleep(5);
//Get the TX from algoexplorer $api_url = "https://algoexplorerapi.io/v2/transactions/pending/".$txid.""; $json_data = file_get_contents($api_url); $response_data = json_decode($json_data, true);
//There are several ways to do this (nonce, check only latest blocks) but this time we will check if transfer is not being reused //Define receiver account and price $account = "K3NSXYMHPRCK7PMYT3QUQXUGPZJ4MKWJXW2HJRYPVMQUMKJAOJEIEO4HK4" $price = 20000 //Look in database if TXID is being reinjected to disallow reusing payments $sql = "SELECT * FROM payments WHERE txid =".$txid.""; $result = $conn->query($sql); //If payment is being reused, exit. Client trying to hack. if (!empty($result)) { exit(); }
//If the paid amount is correct and the receiver address is correct and the product is still on sale process it if ($response_data["txn"]["txn"]["aamt"] == $price) { if ($response_data["txn"]["txn"]["arcv"] == $account) { if ($on_sale == 1) { //Mark product as sold, and save TxId to avoid future reuse $sql = "UPDATE payments set on_sale = 0, txid = $txid, email = $email WHERE id = $id; $conn->query($sql); //DO ACTIONS, for example, sending a confirmation email require 'PHPMailer/src/PHPMailer.php'; (...) $mail->addAddress($email) $mail->send(); }}
