La query est l'ensemble des paires clé-valeur placées après le `?` dans une URL, séparées par des caractères `&`.

Par exemple, dans l'URL :

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

... les paramètres de requête sont :

		0, nil, "", "", nil)
	if err != nil {
		t.Errorf("MinIO %s:Failed to create http request for testing the response when object Layer is set to `nil`.", instanceType)
	}
	// execute the object layer set to `nil` test.
	// `ExecObjectLayerAPINilTest` sets the Object Layer to `nil` and calls the handler.
	ExecObjectLayerAPINilTest(t, nilBucket, nilObject, instanceType, apiRouter, nilReq)

But there are situations where you might need to access the `Request` object directly.

## Details about the `Request` object { #details-about-the-request-object }

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's [`Request`](https://www.starlette.dev/requests/) object directly when you need to.

     * best we can do (since logging may overflow the stack) is to let the error propagate. Because
     * it is an Error, it won't be caught and logged by AbstractFuture.executeListener. Instead, it
     * can propagate through many layers of AbstractTransformFuture up to the root call to set().

     * Other kinds of Errors are possible:

The **default** value of the **function parameter** is the **actual default** value, that's more intuitive with Python in general. 😌
