## Exemple plus poussé

Maintenant, modifiez le fichier `main.py` pour recevoir <abbr title="en anglais : body">le corps</abbr> d'une requête `PUT`.

Déclarez ce corps en utilisant les types Python standards, grâce à Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

			zipw:      w.cw,
			compCount: &countWriter{w: w.cw},
			crc32:     crc32.NewIEEE(),
		}
		comp := w.compressor(fh.Method)
		if comp == nil {
			return nil, ErrAlgorithm
		}
		var err error
		fw.comp, err = comp(fw.compCount)
		if err != nil {
			return nil, err
		}
		fw.rawCount = &countWriter{w: fw.comp}
		fw.header = h
		ow = fw
	}
	w.dir = append(w.dir, h)

    int dummy = 0;
    for (int i = 0; i < reps; i++) {
      StringBuilder sb = new StringBuilder();
      for (String comp : components) {
        if (sb.length() > 0) {
          sb.append(DELIMITER_STRING);
        }
        sb.append(comp);
      }
      dummy ^= sb.toString().length();
    }
    return dummy;
  }

        assertNotNull(mojoDescriptor);
        assertEquals(goal, mojoDescriptor.getGoal());
        // igorf: plugin realm comes later
        // assertNotNull( mojoDescriptor.getRealm() );

        PluginDescriptor pluginDescriptor = mojoDescriptor.getPluginDescriptor();

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    description: str

    {"name": "Foo", "description": "There comes my hero"},
    {"name": "Red", "description": "It's my aeroplane"},

@app.get("/items/", response_model=List[Item])
async def read_items():

    limiter.acquire();
    limiter.acquire();
    limiter.acquire();
    limiter.acquire();
    limiter.acquire();
    assertEvents(
        "R0.00", // First comes the saved-up burst, which defaults to a 1-second burst (2 requests).
        "R0.00", "R0.00", // Now comes the free request.
        "R0.50", // Now it's 0.5 seconds per request.
        "R0.50");

    limiter.setRate(Double.POSITIVE_INFINITY);
    limiter.acquire();

    }

    def "validates present section links"() {
        given:
        sampleDoc << """
[[prior_section]]
Text

=== Valid Section Links
This section comes earlier: <<prior_section>>
This section comes later: <<subsequent_section>>

[[subsequent_section]]
More text
        """

        when:
        run('checkDeadInternalLinks').build()

        then:
        assertNoDeadLinks()

Dans cet exemple, nous n'avons déclaré aucun modèle Pydantic. En fait, le corps de la requête n'est même pas <abbr title="converti d'un format simple, comme des octets, en objets Python">parsé</abbr> en tant que JSON, il est lu directement en tant que `bytes`, et la fonction `magic_data_reader()` serait chargé de l'analyser d'une manière ou d'une autre.

Néanmoins, nous pouvons déclarer le schéma attendu pour le corps de la requête.
