POST 到“/webhook”时出现 Node.js/Express 404 错误

Question

由于某种原因，我收到 404 错误，但仅在向“/webhook”发送发布请求时出现，但我不知道为什么。我的帖子的其余部分都很好，但我不断收到这条消息[404] POST http://localhost:3001/webhook [evt_1IzeQ1EUG2WFNVaczcOMJWgu]

端口 3001 是我的客户端，我的服务器在端口 8080（firebase 模拟器）上运行。知道我做错了什么吗？

  } catch (err) {

// listen command

要在本地测试 Stripe webhook（即在 localhost 上），您需要将这些 webhook 事件转发到您的 localhost 端口。为此，您需要安装和配置Stripe CLI。安装后，您可以使用以下命令对其进行配置：

stripe login

stripe listen --forward-to localhost:5001/webhook

// To manually trigger events using CLI
stripe trigger payment_intent.created

因为如果您从仪表板触发事件，它们将无法到达您的本地主机。

端口号应与 Cloud Functions 模拟器相同，并且完整的 URL 应与您的函数运行的位置相匹配。在你的情况下，“http://localhost:5001/piers-laine/us-central1/api/webhook”
