使用 paypal sdk 找不到 CFC

Question

我正在使用 colfusion paypal SDK 进行直接付款，链接在这里： https://github.com/paypal/nvp-coldfusion-sdk

我在下面粘贴了 application.cfc 文件。我的问题是，每次我转到示例 --> dodirectpayment.cfm 并提交测试表单时，它都会显示“错误：找不到 ColdFusion 组件或接口 CallerService”。我认为这与引用 callerservice.cfc 文件有关，但无法弄清楚出了什么问题。任何帮助深表感谢。 application.cfc 在这里。

Answer 1

getDirectoryFromPath 确实引用了这些文件的实际位置，但由于某种原因，应用程序没有在该位置找到它们。最终的解决方案是将文件复制到与 application.cfc 文件相同的文件夹中，并且一切都按预期工作。谢谢您的帮助。
