## Public Discussions

Please restrain from publicly discussing a potential security vulnerability. 🙊

It's better to discuss privately and try to find a solution first, to limit the potential impact as much as possible.

Thanks for your help!

At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

## More motivation

Check this function, it already has type hints:

```Python hl_lines="1"

```Python hl_lines="1  6"
{!../../../docs_src/response_status_code/tutorial002.py!}
```

They are just a convenience, they hold the same number, but that way you can use the editor's autocomplete to find them:

!!! note "Technical Details"
    You could also use `from starlette import status`.

Just use any kind of model, any kind of class, any kind of database that you need for your application. **FastAPI** has you covered with the dependency injection system.

## Code size

This example might seem verbose. Keep in mind that we are mixing security, data models, utility functions and *path operations* in the same file.

## Server Machine and Server Program

There's a small detail about names to keep in mind. 💡

The word "**server**" is commonly used to refer to both the remote/cloud computer (the physical or virtual machine) and also the program that is running on that machine (e.g. Uvicorn).

Just keep in mind that when you read "server" in general, it could refer to one of those two things.

Just remember, the most important point is: try to be kind. People come with their frustrations and in many cases don't ask in the best way, but try as best as you can to be kind. 🤗

The idea is for the **FastAPI** community to be kind and welcoming. At the same time, don't accept bullying or disrespectful behavior towards others. We have to take care of each other.

* **Standardmäßig** bedeutet das, dass Sie nur **ein HTTPS-Zertifikat pro IP-Adresse** haben können.
    * Ganz gleich, wie groß Ihr Server ist oder wie klein die einzelnen Anwendungen darauf sind.
    * Hierfür gibt es jedoch eine **Lösung**.

    SQLALCHEMY_DATABASE_URL, connect_args={"check_same_thread": False}

# `FastAPI`-Klasse

Hier sind die Referenzinformationen für die Klasse `FastAPI` mit all ihren Parametern, Attributen und Methoden.

Sie können die `FastAPI`-Klasse direkt von `fastapi` importieren:

```python
from fastapi import FastAPI
```

::: fastapi.FastAPI
    options:
        members:
            - openapi_version
            - webhooks
            - state
            - dependency_overrides
            - openapi
