### Die automatische API-Dokumentation testen { #check-the-automatic-api-docs }

Führen Sie nun den Befehl `fastapi` aus:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Und öffnen Sie die Dokumentation unter [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

그런 뒤, 우리는 `FastAPI` 앱을 만들 때 그것을 사용합니다.

그런 다음 환경 변수 `OPENAPI_URL`을 빈 문자열로 설정하여 OpenAPI(UI docs 포함)를 비활성화할 수도 있습니다. 예를 들어:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

그리고 `/openapi.json`, `/docs` 또는 `/redoc`의 URL로 이동하면 `404 Not Found`라는 오류가 다음과 같이 표시됩니다:

```JSON
{

rootdir: /home/user/code/superawesome-cli/app
plugins: forked-1.1.3, xdist-1.31.0, cov-2.8.1
collected 6 items

---> 100%

test_main.py <span style="color: green; white-space: pre;">......                            [100%]</span>

<span style="color: green;">================= 1 passed in 0.03s =================</span>
```

rootdir: /home/user/code/superawesome-cli/app

### 檢查自動 API 文件 { #check-the-automatic-api-docs }

現在，執行 `fastapi` 指令：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然後開啟位於 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) 的文件。

你會看到主應用的自動 API 文件，只包含它自己的*路徑操作*：

                properties:
                  data:
                    type: object
                    properties:
                      status:
                        type: string
                        example: green
                      timed_out:
                        type: boolean
                        example: false
        '400':
          $ref: '#/components/responses/BadRequest'
        '401':

        try {
            context.header = new ArrayList<>();
            context.style = new AttributedStyle();
            context.addInHeader(
                    context.style.italic().bold().foreground(Colors.rgbColor("green")),
                    "Maven Encryption " + CLIReportingUtils.showVersionMinimal());
            context.addInHeader("Tool for secure password management on workstations.");

        try {
            context.header = new ArrayList<>();
            context.style = new AttributedStyle();
            context.addInHeader(
                    context.style.italic().bold().foreground(Colors.rgbColor("green")),
                    "Maven Upgrade " + CLIReportingUtils.showVersionMinimal());
            context.addInHeader("Tool for upgrading Maven projects and dependencies.");

### 자동 API 문서 확인 { #check-the-automatic-api-docs }

이제 `fastapi` 명령어를 실행하세요:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

그리고 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)에서 문서를 여세요.

`--forwarded-allow-ips="*"` とすると、すべての送信元 IP を信頼します。

**サーバー** が信頼できる **プロキシ** の背後にあり、そのプロキシからのみ接続される場合、プロキシの IP を受け入れるようになります。

<div class="termy">

```console
$ fastapi run --forwarded-allow-ips="*"

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

例えば、*path operation* `/items/` を定義しているとします:
