Question

我正在尝试将Paypal实施到我的网站中。但是我遇到了这个错误。

类型错误：传递给PayPal \ Rest \ ApiContext :: setConfig（）的参数1必须为数组类型，给定为null，在D：\ wamp64 \ www \ vonservices \ app \ Http \ Controllers \ PaymentController.php中调用在第40行。这是我的控制器代码：

Answer 1

\Config::get('paypal')是在配置中查找数据的一种旧方法。尝试使用config('paypal')和php artisan config:cache。

Answer 2

我知道很晚了，但是我遇到了同样的问题。解决我的问题的原因是运行

php artisan config:cache

瞧，它为我解决了所有问题。希望它也对其他人有用。
