Paypal IPN未执行许可证创建代码

Question

让我们详细了解…因为我被难住了。

服务器文件结构：

/home/name/public_html/CryptlexApi.php
/home/name/public_html/generate-license.php see below
/home/name/public_html/generate-license-IPN_combined.php
/home/name/public_html/paypalIPN.php 

源

generate-license.php：

<?php
require('CryptlexApi.php');
// pass this secret as query param in the url e.g. https://yourserver.com/generate-license.php?cryptlex_secret=SOME_RANDOM_STRING
$CRYPTLEX_SECRET = "SOME_RANDOM_STRING";
// access token must have following permissions (scope): license:write, user:read, user:write
$PERSONAL_ACCESS_TOKEN = "Yes, I have my PAT here";
// utility functions
function IsNullOrEmptyString($str){
return (!isset($str) || trim($str) === '');
}
function ForbiddenRequest() {
http_response_code(403);
$message['error'] = 'You are not authorized to perform this action!';
echo json_encode($message);
}
function BadRequest($error) {
http_response_code(400);
$message['error'] = $error;
echo json_encode($message);
}
function VerifySecret($secret) {
if($secret == $GLOBALS['CRYPTLEX_SECRET']) {
return true;
}
return false;
}
function parsePayPalPostData() {
$postBody['company'] = $_POST['payer_email'];
if(IsNullOrEmptyString($postBody['email'])) {
$postBody['company'] = "";
}
$postBody['quantity'] = $_POST['quantity'];
if(IsNullOrEmptyString($postBody['quantity'])) {
$postBody['quantity'] = NULL;
}

$postBody['email'] = $_POST['payer_email'];
if(IsNullOrEmptyString($postBody['email'])) {
BadRequest('email is missing!');
return NULL;
}
$postBody['last_name'] = $_POST['last_name'];
if(IsNullOrEmptyString($_POST['last_name'])) {
BadRequest('last name is missing!');
return NULL;
}
$postBody['first_name'] = $_POST['first_name'];
if(IsNullOrEmptyString($_POST['first_name'])) {
BadRequest('first name is missing!');
return NULL;
}
$postBody['order_id'] = $_POST['txn_id'];
if(IsNullOrEmptyString($postBody['order_id'])) {
BadRequest('reference is missing!');
return NULL;
}
return $postBody;
}
try {
if(VerifySecret($_GET['cryptlex_secret']) == false) {
return ForbiddenRequest();
}
CryptlexApi::SetAccessToken($GLOBALS['PERSONAL_ACCESS_TOKEN']);
$product_id = "this is my product id";
$postBody = parsePayPalPostData();
if($postBody == NULL) {
echo "no data n";
return;
}

$email = $postBody['email'];
$first_name = $postBody['first_name'];
$last_name = $postBody['last_name'];
$quantity = $postBody['quantity'];
// required for renewing the license subscription
$order_id = $postBody['order_id'];
// creating user is optional
$user_exists = false;
$user = CryptlexApi::GetUser($email);
if($user == NULL) {
$user_body["email"] = $email;
$user_body["firstName"] = $first_name;
$user_body["lastName"] = $last_name;
$user_body["company"] = $last_name;
// generate a random 8 character password
$user_body["password"] = substr(md5(uniqid()), 0, 8);
$user_body["role"] = "user";
$user = CryptlexApi::CreateUser($user_body);
} else {
$user_exists = true;
}
echo "Quantity = $quantity n";
// creating license
if($quantity != NULL) {
$license_body["allowedActivations"] = (int)$quantity;
}
$license_body["productId"] = $product_id;
$license_body["userId"] = $user->id;
$metadata["key"] = "order_id";
$metadata["value"] = $order_id;
$metadata["visible"] = false;
$license_body["metadata"] = array($metadata);
$license = CryptlexApi::CreateLicense($license_body);
http_response_code(200);
echo $license->key;
} catch(Exception $e) {
http_response_code(500);
echo 'message: ' .$e->getMessage();
}

好的，所以如果我在终端中执行以下操作，我将成功创建一个用户/许可证

curl -d "payer_email=emailaddress%40gmail.com&quantity=1&last_name=smith&first_name=bob&txn_id=ordernumber" -X POST https://mywebsite.com/generate-license.php?cryptlex_secret=SOME_RANDOM_STRING

所以，我把代码放在paypalIPN.php中，并重命名为generate-license-IPN_combined.php在paypalIPN.php文件中，我在这里插入了上面的代码：

// Check if PayPal verifies the IPN data, and if so, return true.
if ($res == self::VALID) {
######## I put all of my code above right here #########
return true;
} else {
return false;
}

IPN代码似乎可以工作，因为Paypal IPN模拟器说它可以。不过，在数据库端什么也没发生。我删除了检查，甚至把这个代码放在IPN之前，但它不起作用。请帮忙。
