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

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
```

     * Get the proxy port.

     */
    public int getPort() {
        return port;
    }

    /**
     * Set the proxy port.
     *
     * @param port proxy server port
     */
    public void setPort(int port) {
        this.port = port;
    }

    /**
     * Get the proxy username.
     *
     * @return username for the proxy server
     */

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
```

Como temos um proxy com um prefixo de caminho de `/api/v1` para nossa aplicação, o frontend precisa buscar o OpenAPI schema em `/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

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：
