FastAPI 會如實將每個資料區塊交給 `StreamingResponse`，不會嘗試將其轉換為 JSON 或其他格式。

### 非 async 路徑操作函式 { #non-async-path-operation-functions }

你也可以使用一般的 `def` 函式（沒有 `async`），並以相同方式使用 `yield`。

{* ../../docs_src/stream_data/tutorial001_py310.py ln[26:29] hl[27] *}

### 不需要型別註解 { #no-annotation }

對於串流二進位資料，其實不需要宣告回傳型別註解。

```

那麼你應該把 `entrypoint` 設為：

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

這等同於：

```python
from backend.main import app
```

### 帶路徑的 `fastapi dev` { #fastapi-dev-with-path }

你也可以把檔案路徑傳給 `fastapi dev` 指令，它會推測要使用的 FastAPI app 物件：

```console
$ fastapi dev main.py
```

但這樣每次呼叫 `fastapi` 指令時都得記得傳入正確的路徑。

不必为你使用的所有标签都添加元数据。

### 使用你的标签 { #use-your-tags }

将 `tags` 参数和*路径操作*（以及 `APIRouter`）一起使用，将其分配给不同的标签：

FastAPI transmettra chaque bloc de données à la `StreamingResponse` tel quel ; il n'essaiera pas de le convertir en JSON ni autre chose similaire.

### Fonctions de chemin d'accès non async { #non-async-path-operation-functions }

Vous pouvez également utiliser des fonctions `def` classiques (sans `async`), et utiliser `yield` de la même manière.

e/windows-amd64/minio.exe ``` Use the following command to run a standalone MinIO server on the Windows host. Replace ``D:\`` with the path to the drive or directory in which you want MinIO to store data. You must change the terminal or powershell directory to the location of the ``minio.exe`` executable, *or* add the path to that directory to the system ``$PATH``: ```sh minio.exe server D:\ ``` The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment...

     * The chain should include all intermediate certificates but does not need the root certificate
