例如，假设你定义了一个*路径操作* `/items/`：

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.py hl[6] *}

如果客户端尝试访问 `/items`，默认会被重定向到 `/items/`。

但在设置 *CLI 选项* `--forwarded-allow-ips` 之前，它可能会重定向到 `http://localhost:8000/items/`。

而你的应用可能托管在 `https://mysuperapp.com`，重定向应当是 `https://mysuperapp.com/items/`。

通过设置 `--proxy-headers`，FastAPI 现在就可以重定向到正确的位置。😎

```
https://mysuperapp.com/items/
```

/// tip | 提示

    // we rule out characters that would cause problems in host headers.
    if (c <= '\u001f' || c >= '\u007f') {
      return true
    }
    // Check for the characters mentioned in the WHATWG Host parsing spec:
    // U+0000, U+0009, U+000A, U+000D, U+0020, "#", "%", "/", ":", "?", "@", "[", "\", and "]"
    // (excluding the characters covered above).
    if (" #%/:?@[\\]".indexOf(c) != -1) {
      return true
    }
  }
  return false
}

Sobald wir eine FastAPI-App mit den Modellen haben, können wir Hey API verwenden, um einen TypeScript-Client zu generieren. Der schnellste Weg das zu tun, ist über npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Dies generiert ein TypeScript-SDK in `./src/client`.

    assert200Http2Response(execute(sanUrl), "san.com")
    assertThat(client.connectionPool.connectionCount()).isEqualTo(1)
    assertThat(connectCount.get()).isEqualTo(1)
