php - Paypal 与 Laravel 5.1 的集成

Question

我正在尝试将支付网关 (paypal) 与 laravel 5.1 集成。我找到了一些适用于 laravel 4 的解决方案，但没有找到适用于 laravel 5.0 及更高版本的解决方案。

我一直在遵循此链接中提到的所有步骤。 xroot/laravel-paypalpayment

但是我在 PaypalPaymentController.php 第 10 行中得到 FatalErrorException:

我附上了我的 Paypal 集成代码和错误的屏幕截图。

Router.php

resource('payment','PaymentController');

app.php

我得到的错误:

Answer 1

我不知道你的代码库，但如果你的类是一个 Controller ，你为什么要扩展一个 Facades 类？问题是您的代码正在寻找 my_app\Http\Controllers 命名空间中的 Facades 类。

删除该行或正确导入该类将解决您的问题。但是，我认为您可能需要重新考虑您的设计。
