Я пытаюсь начать работу, используя интерфейс NVP Paypal для моего веб-сайта для обработки моей пользовательской корзины. Я скачал их пример кода ( здесь ) и попытался запустить без изменений без изменений. Любая выбранная мной функция (например, экспресс-продажа) выдает ошибку curl_errno (): Номер ошибки: 3 Сообщение об ошибке: URL не задан! Я пробовал это как на локальном, так и на моем размещенном сайте.
hash_call () - функция, обрабатывающая вызов Paypal. Код, который вызывает hash_call (), также включен ниже. Их код, который устанавливает URL:
$ returnURL = urlencode ($ url. '/ ReviewOrder.php? CurrencyCodeType ='. $ CurrencyCodeType. '& PaymentType ='. $ PaymentType);
$ cancelURL = urlencode ("$ url / SetExpressCheckout.php? PaymentType = $ paymentType");
Я думал, что строка cancelURL выглядела не так, и изменил ее на:
$ cancelURL = urlencode ($ url. '/ SetExpressCheckout.php? PaymentType ='. $ PaymentType);
Ни один из них не сработал. Любая помощь будет оценена. Я никогда не работал с curl.
