... und **FastAPI** verwendet dieselben Deklarationen, um:

* **Anforderungen** zu definieren: aus <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr>-Pfadparametern, Query-Parametern, Header-Feldern, Bodys, Abhängigkeiten, usw.
* **Daten umzuwandeln**: aus dem Request in den erforderlichen Typ.
* **Daten zu validieren**: aus jedem Request:

/// tip

Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

///

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters

What inspired **FastAPI**, how it compares to alternatives and what it learned from them.

## Intro { #intro }

**FastAPI** wouldn't exist if not for the previous work of others.

There have been many tools created before that have helped inspire its creation.

I have been avoiding the creation of a new framework for several years. First I tried to solve all the features covered by **FastAPI** using many different frameworks, plug-ins, and tools.

        int bodyOffset = Smb2Constants.SMB2_HEADER_LENGTH;
        int securityBufferOffset = SMBUtil.readInt2(buffer, bodyOffset + 12);

        // The offset should point to the location after the fixed structure (relative to header start)
        int expectedOffset = Smb2Constants.SMB2_HEADER_LENGTH + 24;
        while ((expectedOffset % 8) != 0) {
            expectedOffset++; // Account for pad8
        }

En esta excepción, incluimos los scopes requeridos (si los hay) como un string separado por espacios (usando `scope_str`). Ponemos ese string que contiene los scopes en el header `WWW-Authenticate` (esto es parte de la especificación).
