## 定义
|
||
`WEBHOOK_URL` 是 [[n8n]] 的环境变量，用于指定 n8n 实例的公网可访问 HTTPS 地址。
|
||
|
||
## 作用
|
||
- 通知 n8n 使用指定的 HTTPS URL 生成 Webhook URL
|
||
- Telegram / Discord / Slack 等平台要求 Webhook 必须为 HTTPS
|
||
- 自托管 n8n 通过内网穿透（cpolar/FRP）暴露时必须设置此变量
|
||
|
||
## 配置示例
|
||
```bash
|
||
# Docker Compose
|
||
environment:
|
||
- WEBHOOK_URL=https://n8n.ishenwei.online/
|
||
```
|
||
|
||
## 常见错误
|
||
- Telegram Trigger: `Bad Request: bad webhook: An HTTPS URL must be provided for webhook`
|
||
- 原因：`WEBHOOK_URL` 未设置或设置为 HTTP 地址
|
||
- 解决：设置为公网 HTTPS 地址
