```

就能以如下方式调用：

```Python
user_dict = user_in.dict()
```

现在，变量 `user_dict`中的就是包含数据的**字典**（变量 `user_dict` 是字典，不是 Pydantic 模型对象）。

以如下方式调用：

```Python
print(user_dict)
```

输出的就是 Python **字典**：

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': 'john.doe@example.com',
    'full_name': None,
}
```

Então, o que faremos a seguir é adicionar o código para documentar como essa *API externa* deve ser para receber o callback de *sua API*.

A documentação aparecerá na interface do Swagger em `/docs` em sua API, e permitirá que os desenvolvedores externos saibam como construir a *API externa*.

        fmt.Println("Subroute:", GetSubroute(ctx))

            select {
            case <-ctx.Done():
                return nil
            case req, ok := <-in:
                if !ok {
