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`.

{!../../../docs_src/security/tutorial001.py!}
```

!!! tip "豆知識"
    ここで、`tokenUrl="token"`は、まだ作成していない相対URL`token`を指します。相対URLなので、`./token`と同じです。

    相対URLを使っているので、APIが`https://example.com/`にある場合、`https://example.com/token`を参照します。しかし、APIが`https://example.com/api/v1/`にある場合は`https://example.com/api/v1/token`を参照することになります。

    相対 URL を使うことは、[プロキシと接続](../../advanced/behind-a-proxy.md){.internal-link target=_blank}のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

    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.

### 步骤 3：创建一个*路径操作*

#### 路径

这里的「路径」指的是 URL 中从第一个 `/` 起的后半部分。

所以，在一个这样的 URL 中：

```
https://example.com/items/foo
```

...路径会是：

```
/items/foo
```

!!! info
    「路径」也通常被称为「端点」或「路由」。

开发 API 时，「路径」是用来分离「关注点」和「资源」的主要手段。

#### 操作

这里的「操作」指的是一种 HTTP「方法」。

### Krok 3: wykonaj *operację na ścieżce*

#### Ścieżka

"Ścieżka" tutaj odnosi się do ostatniej części adresu URL, zaczynając od pierwszego `/`.

Więc, w adresie URL takim jak:

```
https://example.com/items/foo
```

...ścieżką będzie:

```
/items/foo
```

!!! info
    "Ścieżka" jest zazwyczaj nazywana "path", "endpoint" lub "route'.

```

### Bước 3: tạo một *đường dẫn toán tử*

#### Đường dẫn

"Đường dẫn" ở đây được nhắc tới là phần cuối cùng của URL bắt đầu từ `/`.

Do đó, trong một URL nhìn giống như:

```
https://example.com/items/foo
```

...đường dẫn sẽ là:

```
/items/foo
```

!!! info
    Một đường dẫn cũng là một cách gọi chung cho một "endpoint" hoặc một "route".

	Porque estamos usando uma URL relativa, se sua API estava localizada em `https://example.com/`, então irá referir-se à `https://example.com/token`. Mas se sua API estava localizada em `https://example.com/api/v1/`, então irá referir-se à `https://example.com/api/v1/token`.

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.

## Recap, step by step

### Step 1: import `FastAPI`

```Python hl_lines="1"
{!../../../docs_src/first_steps/tutorial001.py!}
```

```

</div>

### Passo 3: crie uma *rota*

#### Rota

"Rota" aqui se refere à última parte da URL, começando do primeiro `/`.

Então, em uma URL como:

```
https://example.com/items/foo
```

...a rota seria:

```
/items/foo
```

!!! info "Informação"
    Uma "rota" também é comumente chamada de "endpoint".
