Mais il peut y avoir des cas où vous souhaitez pouvoir définir des paramètres sur la dépendance, sans devoir déclarer de nombreuses fonctions ou classes différentes.

Imaginons que nous voulions avoir une dépendance qui vérifie si le paramètre de requête `q` contient un contenu fixe.

Mais nous voulons pouvoir paramétrer ce contenu fixe.

## Une instance « callable » { #a-callable-instance }

func init() {
	testBytes = make([]byte, N)
	for i := 0; i < N; i++ {
		testBytes[i] = 'a' + byte(i%26)
	}
	testString = string(testBytes)
}

// Verify that contents of buf match the string s.
func check(t *testing.T, testname string, buf *Buffer, s string) {
	bytes := buf.Bytes()
	str := buf.String()
	if buf.Len() != len(bytes) {

func (s *xlStorage) WalkDir(ctx context.Context, opts WalkDirOptions, wr io.Writer) (err error) {
	legacyFS := s.fsType != xfs && s.fsType != ext4

	s.RLock()
	legacy := s.formatLegacy
	s.RUnlock()

	// Verify if volume is valid and it exists.
	volumeDir, err := s.getVolDir(opts.Bucket)
	if err != nil {
		return err
	}

	if !skipAccessChecks(opts.Bucket) {
		// Stat a volume entry.

この例外には、要求されたスコープがあればそれらを空白区切りの文字列（`scope_str` を使用）として含めます。このスコープ文字列は `WWW-Authenticate` ヘッダに入れます（仕様の一部です）。

`username` を取得できていることを確認し、スコープを取り出します。

そして、そのデータを Pydantic モデルで検証します（`ValidationError` 例外を捕捉）。JWT トークンの読み取りや Pydantic によるデータ検証でエラーが発生した場合は、先ほど作成した `HTTPException` を送出します。
