我使用 PayPal Api 创建加密的 BuyNow 按钮。 Api 返回按钮作为表单 HTML 代码。

问题是我不想将 FORM 用于 paypal 按钮，而且我也找不到更改嵌入在表单 html 代码中的默认 paypal 按钮的方法。我想使用加密的 Paypal 按钮作为简单的文本链接。
我试图只复制所有表单变量并使用类似的参数构建 url

不幸的是，它不起作用。也许有人有解决方案？
最佳答案
在 BMCreateButton API 调用中，设置 BUTTONTYPE=HOSTED 而不是 BUTTONTYPE=ENCRYPTED。它在安全方面是相同的，但它还会返回一个“EMAILLINK”，您可以随后使用它。
很遗憾，BUTTONTYPE=ENCRYPTED 不会返回 EMAILLINK。
此外，如果您在链接中包含完整的加密文本，您可能会遇到 Apache 中的 LimitRequestLine 限制(默认值:8190)，具体取决于您的 Apache 配置。
保持 URL 尽可能短要好得多。
