#### 在 TLS 终止代理后面 { #behind-a-tls-termination-proxy }

如果你在 Nginx 或 Traefik 等 TLS 终止代理（负载均衡器）后面运行容器，请添加 `--proxy-headers` 选项，这会通过 FastAPI CLI 告诉 Uvicorn 信任该代理发送的标头，表明应用运行在 HTTPS 后等。

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```

當你像上面那樣掛載子應用程式時，FastAPI 會使用 ASGI 規範中的一個機制 `root_path`，將子應用程式的掛載路徑告知它。

如此一來，子應用程式就會知道在文件 UI 使用該路徑前綴。

而且子應用程式也能再掛載自己的子應用程式，一切都能正確運作，因為 FastAPI 會自動處理所有這些 `root_path`。
