**強烈建議**你編寫或複製程式碼、進行修改並在本地端運行。

在編輯器中使用它，才能真正體會到 FastAPI 的好處，可以看到你只需編寫少量程式碼，以及所有的型別檢查、自動補齊等功能。

### アプリケーション検出 { #application-discovery }

既定では、ワークスペース内で `FastAPI()` を生成しているファイルを走査し、FastAPI アプリケーションを自動検出します。プロジェクト構成の都合で自動検出が機能しない場合は、`pyproject.toml` の `[tool.fastapi]`、または VS Code 設定の `fastapi.entryPoint` にモジュール記法（例: `myapp.main:app`）でエントリポイントを指定できます。

它甚至可以是一个无限流，你可以一直持续发送数据。

## JSON Lines { #json-lines }

在这些场景中，常见的做法是发送 “JSON Lines”，这是一种每行发送一个 JSON 对象的格式。

响应的内容类型是 `application/jsonl`（而不是 `application/json`），响应体类似这样：

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}
{"name": "Portal Gun", "description": "A portal opening device."}

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Waiting for application startup.
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Application startup complete.
```

</div>

在输出中，会有一行信息像下面这样：

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

    // START SNIPPET: ear
    private static final String[] BINDINGS = {
        "generate-resources",
                "org.apache.maven.plugins:maven-ear-plugin:" + EAR_PLUGIN_VERSION + ":generate-application-xml",
        "process-resources",
                "org.apache.maven.plugins:maven-resources-plugin:" + RESOURCES_PLUGIN_VERSION + ":resources",

파일과 폼 필드는 폼 데이터로 업로드되며, 파일과 폼 필드를 받게 됩니다.

또한 일부 파일은 `bytes`로, 일부 파일은 `UploadFile`로 선언할 수 있습니다.

/// warning

다수의 `File`과 `Form` 매개변수를 한 *경로 처리*에 선언하는 것이 가능하지만, 요청의 본문이 `application/json`가 아닌 `multipart/form-data`로 인코딩되기 때문에 JSON으로 받기를 기대하는 `Body` 필드를 함께 선언할 수는 없습니다.

이는 **FastAPI**의 한계가 아니라, HTTP 프로토콜의 일부입니다.

データを送り続ける無限ストリームにすることもできます。

## JSON Lines { #json-lines }

このような場合、1 行に 1 つの JSON オブジェクトを送る「**JSON Lines**」形式を使うのが一般的です。

レスポンスの content type は `application/jsonl`（`application/json` の代わり）となり、ボディは次のようになります:

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}
{"name": "Portal Gun", "description": "A portal opening device."}
