    如果您需要异步连接到关系数据库，请参阅[Async SQL (Relational) Databases](https://fastapi.tiangolo.com/zh/advanced/async-sql-databases/)

!!! note "Very Technical Details"
    如果您很好奇并且拥有深厚的技术知识，您可以在[Async](https://fastapi.tiangolo.com/zh/async/#very-technical-details)文档中查看有关如何处理 `async def`于`def`差别的技术细节。

## 迁移

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

**Note**:

如果你不知道是否会用到，可以查看文档的 _"In a hurry?"_ 章节中 <a href="https://fastapi.tiangolo.com/zh/async/#in-a-hurry" target="_blank">关于 `async` 和 `await` 的部分</a>。
