## Recap

Having **HTTPS** is very important, and quite **critical** in most cases. Most of the effort you as a developer have to put around HTTPS is just about **understanding these concepts** and how they work.

Password: `secret2`

And try to use the operation `GET` with the path `/users/me`.

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap

You now have the tools to implement a complete security system based on `username` and `password` for your API.

You can learn how to use them and how they are integrated into **FastAPI** later in the **Advanced User Guide**.

## Recap

With what you have seen up to now, you can set up a secure **FastAPI** application using standards like OAuth2 and JWT.

In almost any framework handling the security becomes a rather complex subject quite quickly.

    !!! tip
        Prefer to use the `Annotated` version if possible.

## Recap

Use the *path operation decorator's* parameter `response_model` to define response models and especially to ensure private data is filtered out.

## Recap

You can use Pydantic Settings to handle the settings or configurations for your application, with all the power of Pydantic models.

* By using a dependency you can simplify testing.
* You can use `.env` files with it.

You can use simple tools like `htop` to see the CPU and RAM used in your server or the amount used by each process. Or you can use more complex monitoring tools, which may be distributed across servers, etc.

## Recap

You have been reading here some of the main concepts that you would probably need to keep in mind when deciding how to deploy your application:

* Security - HTTPS
* Running on startup
* Restarts

* The alternative documentation will also reflect the new query parameter and body:

### Recap

In summary, you declare **once** the types of parameters, body, etc. as function parameters.

You do that with standard modern Python types.

* **<abbr title="Short">کوچک</abbr>**: کاهش تکرار در کد. چندین قابلیت برای هر پارامتر (منظور پارامترهای ورودی تابع هندلر می‌باشد، به بخش <a href="https://fastapi.tiangolo.com/#recap">خلاصه</a> در همین صفحه مراجعه شود). باگ کمتر.
* **<abbr title="Robust">استوار</abbr>**: ایجاد کدی آماده برای استفاده در محیط پروداکشن و تولید خودکار <abbr title="Interactive documentation">مستندات تعاملی</abbr>
