Néanmoins, cela reste faisable dans **FastAPI**, via les outils internes de Starlette.

Et la documentation fonctionne quand même, bien qu'aucune section ne soit ajoutée pour dire que la paramètre devrait contenir un *chemin*.

### Convertisseur de *chemin*

En utilisant une option de Starlette directement, vous pouvez déclarer un *paramètre de chemin* contenant un *chemin* avec une URL comme :

		var wg sync.WaitGroup
		wg.Add(2)
		didRead := make(chan bool, 1)
		// Read in one goroutine.
		go func() {
			defer wg.Done()
			data, err := io.ReadAll(r.Body)
			if string(data) != reqBody {
				t.Errorf("Handler read %q; want %q", data, reqBody)
			}
			if err != nil {
				t.Errorf("Handler Read: %v", err)
			}
			didRead <- true
		}()
		// Write in another goroutine.
		go func() {

		}
	}()
	b.Read(make([]byte, 100))
}

var errFake = errors.New("fake error")

type errorThenGoodReader struct {
	didErr bool
	nread  int
}

func (r *errorThenGoodReader) Read(p []byte) (int, error) {
	r.nread++
	if !r.didErr {
		r.didErr = true
		return 0, errFake
	}
	return len(p), nil
}

func TestReaderClearError(t *testing.T) {
	r := &errorThenGoodReader{}
