我正在尝试将 payflow pro 与现有网站集成。
没有适用于 PHP 的 SDK，与 PHP 的集成需要使用 Payflow HTTPS 接口。开发指南（https://cms.paypal.com/cms_content/AU/en_AU/files/developer/PP_WPPPF_HTTPSInterface_Guide.pdf）说我需要编写代码来创建到 Paypal 服务器的 HTTPS 连接。我应该使用什么方法来执行此操作，以及在建立连接后如何提交 HTTPS 请求？
【问题讨论】：
标签： php https http-headers payflowpro
只需使用任何常规方法发出 HTTP 请求，例如卷曲或file_get_contents。如果底层传输层支持 SSL 安全连接，则向https://... URL 发出请求将建立 SSL 安全连接；否则传输层将失败，说它无法建立 HTTPS 连接。

您有三个选择：
1) 如果您喜欢冒险，可以使用 OSCommerce PHP PayFlow SDK 作为起点：https://www.x.com/sites/default/files/OsC23PayPalPayFlow.zip
2) 您可以通读 payflow 开发指南并进行自己的手工 API 调用： https://cms.paypal.com/cms_content/US/en_US/files/developer/PP_PayflowPro_Guide.pdf
3) 您可以试一试集成向导。我会为你自动生成代码：https://www.paypal-labs.com/integrationwizardccpayflow/main.php
