* until a nonzero result is found; imposes "dictionary order." If the end of one iterable is
   * reached, but not the other, the shorter iterable is considered to be less than the longer one.
   * For example, a lexicographical natural ordering over integers considers {@code [] < [1] < [1,
   * 1] < [1, 2] < [2]}.

Voyons comment procéder.

## Créer un middleware { #create-a-middleware }

Pour créer un middleware, utilisez le décorateur `@app.middleware("http")` au-dessus d’une fonction.

La fonction de middleware reçoit :

# This is more or less a workaround to make Depends and Security hashable
# as other tools that use them depend on that
# Ref: https://github.com/fastapi/fastapi/pull/14320

from fastapi import Depends, Security


def dep():
    pass


def test_depends_hashable():
    dep()  # just for coverage
    d1 = Depends(dep)
    d2 = Depends(dep)
    d3 = Depends(dep, scope="function")
    d4 = Depends(dep, scope="function")

## 숫자 검증: 크거나 및 작거나 같음 { #number-validations-greater-than-and-less-than-or-equal }

동일하게 적용됩니다:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## 숫자 검증: 부동소수, 크거나 및 작거나 { #number-validations-floats-greater-than-and-less-than }

숫자 검증은 `float` 값에도 동작합니다.

## 数值校验：大于和小于等于 { #number-validations-greater-than-and-less-than-or-equal }

同样适用于：

* `gt`：大于（`g`reater `t`han）
* `le`：小于等于（`l`ess than or `e`qual）

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py310.py hl[10] *}

## 数值校验：浮点数、大于和小于 { #number-validations-floats-greater-than-and-less-than }

数值校验同样适用于 `float` 值。

      metadata:
        - key: content-type
          value: image/* # match objects with 'content-type', all values starting with 'image/'
      size:
        lessThan: "10MiB" # match objects with size less than this value (e.g. 10MiB)
        greaterThan: 1MiB # match objects with size greater than this value (e.g. 1MiB)
      purge:
          # retainVersions: 0 # (default) delete all versions of the object. This option is the fastest.

Par exemple, elle ne reçoit pas d'objets `datetime`, car ceux-ci ne sont pas compatibles avec JSON.

Ainsi, un objet `datetime` doit être converti en une `str` contenant les données au [format ISO](https://en.wikipedia.org/wiki/ISO_8601).

De la même manière, cette base de données n'accepterait pas un modèle Pydantic (un objet avec des attributs), seulement un `dict`.
