我在想以下代码的“Pay Now”按钮有什么问题。点击它后，它会显示网站上的错误消息“错误处理付款”（https://securepayments.sandbox.paypal.com/cgi-bin/webscr）。“Pay Now”按钮在buttonmanager-sdk-dotnet SDK示例项目中不起作用
我使用了git集线器中的buttonmanager-sdk-dotnet，并且按照soap响应中的说明生成按钮代码。为了生成“立即购买”按钮，似乎没问题，我可以点击并从PayPal查看付款页面，而不是错误页面。
这真的让我感到困惑。谁能帮我？
谢谢！

我改变了帖子的URL，它仍然无法正常工作。包含URL的HTML表单通过API调用返回，应该没问题。我猜这个账户没有为交易类型付款设置。该错误消息对错误页面也不是很有帮助。 – 2013-03-26 19:16:02
