事件订阅 · Cloudflare Workers docs

事件订阅允许您在 Cloudflare 账户中发生事件时接收消息。Cloudflare 产品（例如 KV、Workers AI、Workers）可以将结构化事件发布到队列，然后您可以使用 Workers 或 HTTP 拉取消费者来消费这些事件，以构建自定义工作流、集成或逻辑。

有关事件订阅的更多信息，请参阅管理指南。

发送构建通知

你可以部署一个 Worker 来消费构建事件并将通知发送到 Slack、Discord 或任何 webhook 端点：

该模板会为以下情况发送通知：

包含预览或实时部署 URL 的成功构建
包含错误消息的失败构建
已取消的构建

你可以自定义 Worker 以按 webhook 提供商格式化消息。有关设置说明，请参阅模板 README ↗。
