We also saw that HTTPS is normally provided by a component **external** to your application server, a **TLS Termination Proxy**.

And there has to be something in charge of **renewing the HTTPS certificates**, it could be the same component or it could be something different.

### Example Tools for HTTPS { #example-tools-for-https }

Some of the tools you could use as a TLS Termination Proxy are:

Nevertheless, we can declare the expected schema for the request body.

### Custom OpenAPI content type { #custom-openapi-content-type }

* Un **<abbr title="aussi connu sous le nom de composants, ressources, fournisseurs, services, injectables">système d'injection de dépendance </abbr>** très puissant et facile à utiliser .
* Sécurité et authentification, y compris la prise en charge de **OAuth2** avec les **<abbr title="en anglais : JWT tokens">jetons <abbr title="JSON Web Tokens">JWT</abbr></abbr>** et l'authentification **HTTP Basic**.

## Override the default exception handlers { #override-the-default-exception-handlers }

**FastAPI** has some default exception handlers.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

When you do this, the examples will be part of the internal **JSON Schema** for that body data.

Nevertheless, at the <abbr title="2023-08-26">time of writing this</abbr>, Swagger UI, the tool in charge of showing the docs UI, doesn't support showing multiple examples for the data in **JSON Schema**. But read below for a workaround.

### OpenAPI-specific `examples` { #openapi-specific-examples }

#### Define a *path operation decorator* { #define-a-path-operation-decorator }

{* ../../docs_src/first_steps/tutorial001.py hl[6] *}

The `@app.get("/")` tells **FastAPI** that the function right below is in charge of handling requests that go to:

* the path `/`
* using a <abbr title="an HTTP GET method"><code>get</code> operation</abbr>

/// info | `@decorator` Info

        // Protocol ID
        System.arraycopy(new byte[] { (byte) 0xFE, 'S', 'M', 'B' }, 0, buffer, headerStart, 4);
        // Structure size (64)
        SMBUtil.writeInt2(64, buffer, headerStart + 4);
        // Credit charge
        SMBUtil.writeInt2(1, buffer, headerStart + 6);
        // Status
        SMBUtil.writeInt4(0, buffer, headerStart + 8);
        // Command (READ = 0x0008)

## Where are Packages Installed { #where-are-packages-installed }

When you install Python, it creates some directories with some files in your computer.

Some of these directories are the ones in charge of having all the packages you install.

When you run:

<div class="termy">

```console
// Don't run this now, it's just an example 🤓
$ pip install "fastapi[standard]"
---> 100%
```
