## Ajouter des validations par expressions régulières

On peut définir une <abbr title="Une expression régulière, regex ou regexp est une suite de caractères qui définit un pattern de correspondance pour les chaînes de caractères.">expression régulière</abbr> à laquelle le paramètre doit correspondre :

```Python hl_lines="10"

        assertEquals(".*domain.com/.*", systemHelper.normalizeConfigPath(".*domain.com/.*"));
        assertEquals("aaa", systemHelper.normalizeConfigPath("regexp:aaa"));
        assertEquals("aaa", systemHelper.normalizeConfigPath("regexpCase:aaa"));
        assertEquals("(?i)aaa", systemHelper.normalizeConfigPath("regexpIgnoreCase:aaa"));
    }

     * <pre>
     * message: {item} must match "{regexp}".
     * </pre>
     * @param property The property name for the message. (NotNull)
     * @param regexp The parameter regexp for message. (NotNull)
     * @return this. (NotNull)
     */
    public FessMessages addConstraintsPatternMessage(String property, String regexp) {
        assertPropertyNotNull(property);

package tests_test

import (
	"errors"
	"fmt"
	"regexp"
	"testing"
	"time"

	"github.com/jinzhu/now"
	"gorm.io/gorm"
	"gorm.io/gorm/clause"
	. "gorm.io/gorm/utils/tests"
)

func TestCreate(t *testing.T) {
	user := *GetUser("create", Config{})

	if results := DB.Create(&user); results.Error != nil {
		t.Fatalf("errors happened when create: %v", results.Error)
	} else if results.RowsAffected != 1 {

매개변수 `min_length` 또한 추가할 수 있습니다:

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial003.py!}
```

## 정규식 추가

매개변수와 일치해야 하는 <abbr title="정규표현식(regular expression), regex 또는 regexp는 문자열 조회 패턴을 정의하는 문자들의 순열입니다">정규표현식</abbr>을 정의할 수 있습니다:

```Python hl_lines="10"
{!../../../docs_src/query_params_str_validations/tutorial004.py!}
```

이 특정 정규표현식은 전달 받은 매개변수 값을 검사합니다:

# only executabe on the RBE (x86) machine, so the strategy_regexp options are
# added to override and run the actions using remote strategy.
build:rbe_cross_compile_base_xla --strategy_regexp='Generating code from table.*=remote'
build:rbe_cross_compile_base_xla --strategy_regexp='Generating flatbuffer files.*=remote'
build:rbe_cross_compile_base_xla --strategy_regexp='Executing genrule @llvm-project.*=remote'

// Identifier represents a parsed identifier
type Identifier struct {
	Unquoted *string           `parser:"  @Ident"`
	Quoted   *QuotedIdentifier `parser:"| @QuotIdent"`
}

var (
	sqlLexer = lexer.Must(lexer.Regexp(`(\s+)` +
		`|(?P<Timeword>(?i)\b(?:YEAR|MONTH|DAY|HOUR|MINUTE|SECOND|TIMEZONE_HOUR|TIMEZONE_MINUTE)\b)` +
