# About HTTPS

It is easy to assume that HTTPS is something that is just "enabled" or not.

But it is way more complex than that.

!!! tip
    If you are in a hurry or don't care, continue with the next sections for step by step instructions to set everything up with different techniques.

To **learn the basics of HTTPS**, from a consumer perspective, check <a href="https://howhttps.works/" class="external-link" target="_blank">https://howhttps.works/</a>.

* Go to the "Debug" panel.
* "Add configuration...".
* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:

If you use Pycharm, you can:

* Open the "Run" menu.
* Select the option "Debug...".

* Any program, any code, **can only do things** when it is being **executed**. So, when there's a **process running**.
* The process can be **terminated** (or "killed") by you, or by the operating system. At that point, it stops running/being executed, and it can **no longer do things**.

# 关于 HTTPS

人们很容易认为 HTTPS 仅仅是“启用”或“未启用”的东西。

但实际情况比这复杂得多。

!!!提示
     如果你很赶时间或不在乎，请继续阅读下一部分，下一部分会提供一个step-by-step的教程，告诉你怎么使用不同技术来把一切都配置好。

要从用户的视角**了解 HTTPS 的基础知识**，请查看 <a href="https://howhttps.works/" class="external-link" target="_blank">https://howhttps.works/</a>。

现在，从**开发人员的视角**，在了解 HTTPS 时需要记住以下几点：

* 要使用 HTTPS，**服务器**需要拥有由**第三方**生成的**"证书(certificate)"**。
     * 这些证书实际上是从第三方**获取**的，而不是“生成”的。
* 证书有**生命周期**。
     * 它们会**过期**。

# Tutorial - User Guide

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference.

So you can come back and see exactly what you need.

## Run the code

This could be useful if for example you live in a country that restricts some URLs.

### Disable the automatic docs

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

```Python hl_lines="8"

    Thông tin ở đây được biểu thị như là một chỉ dẫn, không phải là một yêu cầu bắt buộc.

    Ví dụ, khi sử dụng GraphQL bạn thông thường thực hiện tất cả các hành động chỉ bằng việc sử dụng các toán tử `POST`.

### Step 4: Định nghĩa **hàm cho đường dẫn toán tử**

Đây là "**hàm cho đường dẫn toán tử**":

* **đường dẫn**: là `/`.
* **toán tử**: là `get`.
* **hàm**: là hàm bên dưới "decorator" (bên dưới `@app.get("/")`).

Sie können einfache Tools wie `htop` verwenden, um die in Ihrem Server verwendete CPU und den RAM oder die von jedem Prozess verwendete Menge anzuzeigen. Oder Sie können komplexere Überwachungstools verwenden, die möglicherweise auf mehrere Server usw. verteilt sind.

!!! tip

    This is the main line that you would have to modify if you wanted to use a different database.

### Create the SQLAlchemy `engine`

The first step is to create a SQLAlchemy "engine".

We will later use this `engine` in other places.

```Python hl_lines="8-10"
{!../../../docs_src/sql_databases/sql_app/database.py!}
```
