Because we have a proxy with a path prefix of `/api/v1` for our app, the frontend needs to fetch the OpenAPI schema at `/api/v1/openapi.json`.

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

!!! tip

Da wir für unsere Anwendung einen Proxy mit dem Pfadpräfix `/api/v1` haben, muss das Frontend das OpenAPI-Schema unter `/api/v1/openapi.json` abrufen.

```mermaid
graph LR

browser("Browser")
proxy["Proxy auf http://0.0.0.0:9999/api/v1/app"]
server["Server auf http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

🩺 🎚 🔜 💪 🗄 🔗 📣 👈 👉 🛠️ `server` 🔎 `/api/v1` (⛅ 🗳). 🖼:

这是因为应用使用了以 `/api/v1` 为路径前缀的代理，前端要从 `/api/v1/openapi.json`  中提取 OpenAPI 概图。

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

!!! tip "提示"

    IP `0.0.0.0` 常用于指程序监听本机或服务器上的所有有效 IP。

API 文档还需要 OpenAPI 概图声明 API `server` 位于 `/api/v1`（使用代理时的 URL）。例如：

        'prop1' | 'listProperty()'      | 'List'        | '<T>'
        'prop2' | 'setProperty()'       | 'Set'         | '<T>'
        'prop3' | 'mapProperty()'       | 'Map'         | '<K, V>'
        'prop4' | 'directoryProperty()' | 'Directory'   | ''
        'prop5' | 'fileProperty()'      | 'RegularFile' | ''
    }
