*在这里，我们在路径操作函数*和依赖项中都使用着 SQLAlchemy 模型，它将与外部数据库进行通信。

这会需要一些“等待时间”。

但是由于 SQLAlchemy 不具有`await`直接使用的兼容性，因此类似于：

```Python
user = await db.query(User).first()
```

...相反，我们可以使用：

```Python
user = db.query(User).first()
```

然后我们应该声明*路径操作函数*和不带 的依赖关系`async def`，只需使用普通的`def`，如下：

```Python hl_lines="2"
@app.get("/users/{user_id}", response_model=schemas.User)

    cookie_params = _get_flat_fields_from_params(flat_dependant.cookie_params)
    parameter_groups = [
        (ParamTypes.path, path_params),
        (ParamTypes.query, query_params),
        (ParamTypes.header, header_params),
        (ParamTypes.cookie, cookie_params),
    ]
    for param_type, param_group in parameter_groups:
        for param in param_group:

)

    values = if_oss(

		return AuthNResponse{}, fmt.Errorf("Invalid role ARN value: %s", roleArn.String())
	}

	u := url.URL(*o.args.URL)
	q := u.Query()
	q.Set("token", token)
	u.RawQuery = q.Encode()

	ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
	defer cancel()
