Paypal

经典API

'enabled'    => true,
'username'   => 'schtr4jh-facilitator_api1.schtr4jh.net',

    'level'   => 'DEBUG', // 'FINE' for production
],

预付款

配置

'enabled'     => false,
'url_waiting' => 'payment.waiting',

实现

每个项目都需要实现 \Pckg\Payment\Adapter\Order|Product|Customer|Log|Environment (称为 ProjectOrder, ProjectProduct, ProjectCustomer 和 ProductLog)，它提供适当的映射器。对于Laravel项目，您可以使用 Pckg\Payment\Service\LaravelPayment trait，该trait使用Laravel环境创建支付服务，用于处理请求、响应、URL生成和重定向。对于其他项目，只需实现 Payment\Adapter\Environment。

路由

// list payments
'payment'          => route('PaymentController@payment', 'payment/{listing}', 'GET'),

// apply promo code
'payment.promo'    => route('PaymentController@promo', 'payment/{handler}/{listing}/promo', 'POST'),

// validate payment request
'payment.validate' => route('PaymentController@validate', 'payment/{handler}/{listing}/validate', 'POST'),

// start payment process
'payment.start'    => route('PaymentController@start', 'payment/{handler}/{listing}/start', 'POST|GET'),

// payment valid
'payment.success'  => route('PaymentController@success', 'payment/{handler}/{listing}/success', 'GET'),

// payment invalid
'payment.error'    => route('PaymentController@error', 'payment/{handler}/{listing}/error', 'GET'),

// payment not processed yet
'payment.waiting'  => route('PaymentController@waiting', 'payment/{handler}/{listing}/waiting', 'GET'),
