```Python
some_variable: PlaneItem | CarItem
```

Mais si nous écrivons cela dans l'affectation `response_model=PlaneItem | CarItem`, nous obtiendrons une erreur, car Python essaierait d'effectuer une « opération invalide » entre `PlaneItem` et `CarItem` au lieu de l'interpréter comme une annotation de type.

FastAPI 会将每个数据块原样交给 `StreamingResponse`，不会尝试将其转换为 JSON 或做类似处理。

### 非 async 的*路径操作函数* { #non-async-path-operation-functions }

你也可以使用常规的 `def` 函数（不带 `async`），并以相同方式使用 `yield`。

### 无需注解 { #no-annotation }

你其实不需要为流式二进制数据声明返回类型注解。
