Webargs est un outil qui a été créé pour fournir cela par-dessus plusieurs frameworks, dont Flask.

Il utilise Marshmallow pour effectuer la validation des données. Et il a été créé par les mêmes développeurs.

C'est un outil formidable et je l'ai beaucoup utilisé aussi, avant d'avoir **FastAPI**.

Mais vous voulez aussi qu'il accepte de nouveaux éléments. Et lorsque les éléments n'existaient pas auparavant, il les crée et renvoie un code HTTP de 201 "Créé".

Pour y parvenir, importez `JSONResponse` et renvoyez-y directement votre contenu, en définissant le `status_code` que vous souhaitez :

{* ../../docs_src/additional_status_codes/tutorial001.py hl[4,25] *}

For this, we use `security_scopes.scopes`, that contains a `list` with all these scopes as `str`.

{* ../../docs_src/security/tutorial005_an_py310.py hl[130:136] *}

## Dependency tree and scopes { #dependency-tree-and-scopes }

Let's review again this dependency tree and the scopes.

This directory holds snapshots of the crypto/internal/fips140 tree
that are being validated and certified for FIPS-140 use.
The file x.txt (for example, inprocess.txt, certified.txt)
defines the meaning of the FIPS version alias x, listing
the exact version to use.

The zip files are created by cmd/go/internal/fips140/mkzip.go.
The fips140.sum file lists checksums for the zip files.
