Da wir eine relative URL verwenden, würde sich das, wenn sich Ihre API unter `https://example.com/` befindet, auf `https://example.com/token` beziehen. Wenn sich Ihre API jedoch unter `https://example.com/api/v1/` befände, würde es sich auf `https://example.com/api/v1/token` beziehen.

/// tip | 提示

在此，`tokenUrl="token"` 指向的是暂未创建的相对 URL `token`。这个相对 URL 相当于 `./token`。

因为使用的是相对 URL，如果 API 位于 `https://example.com/`，则指向 `https://example.com/token`。但如果 API 位于 `https://example.com/api/v1/`，它指向的就是`https://example.com/api/v1/token`。

使用相对 URL 非常重要，可以确保应用在遇到[使用代理](../../advanced/behind-a-proxy.md){.internal-link target=_blank}这样的高级用例时，也能正常运行。

///

该参数不会创建端点或*路径操作*，但会声明客户端用来获取令牌的 URL `/token` 。此信息用于 OpenAPI 及 API 文档。

Because we are using a relative URL, if your API was located at `https://example.com/`, then it would refer to `https://example.com/token`. But if your API was located at `https://example.com/api/v1/`, then it would refer to `https://example.com/api/v1/token`.

Using a relative URL is important to make sure your application keeps working even in an advanced use case like [Behind a Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}.
