- Added a path `/header?key=` to `agnhost netexec` allowing one to view what the header value is of the incoming request.

  Ex:
  ```
  $ curl -H "X-Forwarded-For: something" 172.17.0.2:8080/header?key=X-Forwarded-For
  something
  ```

FastAPI 已經整合了安全性和身份驗證的功能，但不會強制與特定的資料庫或資料模型進行綁定。

OpenAPI 中定義的安全模式，包括：

* HTTP 基本認證。
* **OAuth2**（也使用 **JWT tokens**）。在 [OAuth2 with JWT](tutorial/security/oauth2-jwt.md) 查看教學。
* API 密鑰，在：
    * 標頭（Header）
    * 查詢參數
    * Cookies，等等。

加上來自 Starlette（包括 **session cookie**）的所有安全特性。

所有的這些都是可重複使用的工具和套件，可以輕鬆與你的系統、資料儲存（Data Stores）、關聯式資料庫（RDBMS）以及非關聯式資料庫（NoSQL）等等整合。

随后 Traefik 会把请求转发到运行在 `http://127.0.0.1:8000` 的 Uvicorn。

现在启动 Traefik：

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

然后使用 `--root-path` 选项启动你的应用：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1
