Paypal Webhook验证每次都会失败

问题描述

我已经使用Paypal中的Sandbox成功实现了Webhook集成。 现在,我想使其更加安全,以便仅接受贝宝签名的通知。 我试图使用来验证Webhook签名

https://developer.paypal.com/docs/api/webhooks/v1/#verify-webhook-signature_post

但是它总是返回 FAILURE

请求是:

结果是

{“ verification_status”:“失败”}

有人可以帮忙吗!

解决方法

如果您像他们在文档中所说的那样从 webhook 模拟器中获取这些值,则您无法验证模拟 webhook。

当我需要验证值时,我曾经做过什么,因为某些测试需要那部分,即使用智能按钮生成请求,然后在某个 webhook 中捕获响应。
