We can use **OAuth2** to build that with **FastAPI**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

f define&&define.amd?define(["jquery"],function(a){return b(a)}):"object"==typeof module&&module.exports?module.exports=b(require("jquery")):b(a.jQuery)}(this,function(a){!function(a,b){"use strict";a.formUtils.registerLoadedModule("lang/ko"),a(b).bind("validatorsLoaded",function(){a.formUtils.LANG={errorTitle:"이 양식은 보낼 수 없습니다!",requiredField:"필수 입력란입니다.",requiredFields:"모든 필수 입력란을 입력해야 합니다.",badTime:"시간을 정확하게 입력하지 않았습니다.",badEmail:"e-mail을 정확하게 입력하지 않았습니다.",badTelephone:"전화번호를 정확하게 입력하지 않았습니다."...

Das Verstecken Ihrer Dokumentationsoberflächen in der Produktion *sollte nicht* die Methode sein, Ihre API zu schützen.

Dadurch wird Ihrer API keine zusätzliche Sicherheit hinzugefügt, die *Pfadoperationen* sind weiterhin dort verfügbar, wo sie sich befinden.

Wenn Ihr Code eine Sicherheitslücke aufweist, ist diese weiterhin vorhanden.

Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.

„Mounten“ („Einhängen“) bedeutet das Hinzufügen einer völlig „unabhängigen“ Anwendung an einem bestimmten Pfad, die sich dann um die Handhabung aller unter diesem Pfad liegenden _Pfadoperationen_ kümmert, welche in dieser Unteranwendung deklariert sind.

### Hauptanwendung

Erstellen Sie zunächst die Hauptanwendung **FastAPI** und deren *Pfadoperationen*:

You can see the defined cookies in the docs UI at `/docs`:

Have in mind that, as **browsers handle cookies** in special ways and behind the scenes, they **don't** easily allow **JavaScript** to touch them.
