## `/token` パスオペレーションの更新

トークンの有効期限を表す`timedelta`を作成します。

JWTアクセストークンを作成し、それを返します。

### JWTの"subject" `sub` についての技術的な詳細

JWTの仕様では、トークンのsubjectを表すキー`sub`があるとされています。

使用するかどうかは任意ですが、`sub`はユーザーの識別情報を入れるように規定されているので、ここで使用します。

JWTは、ユーザーを識別して、そのユーザーがAPI上で直接操作を実行できるようにする以外にも、他の用途で使用されることがあります。

例えば、「車」や「ブログ記事」を識別することができます。

func TestS390XOperandParser(t *testing.T) {
	parser := newParser("s390x")
	testOperandParser(t, parser, s390xOperandTests)
}

func TestFuncAddress(t *testing.T) {
	type subtest struct {
		arch  string
		tests []operandTest
	}
	for _, sub := range []subtest{
		{"amd64", amd64OperandTests},
		{"386", x86OperandTests},
		{"arm", armOperandTests},
		{"arm64", arm64OperandTests},
		{"ppc64", ppc64OperandTests},

### Detalles técnicos sobre el "sujeto" `sub` de JWT { #technical-details-about-the-jwt-subject-sub }

La especificación de JWT dice que hay una clave `sub`, con el sujeto del token.

Es opcional usarlo, pero ahí es donde pondrías la identificación del usuario, por lo que lo estamos usando aquí.

	if len(args) > 0 {
		tx = tx.Select(args[0], args[1:]...)
	}
	return
}

// Select specify fields that you want when querying, creating, updating
//
// Use Select when you only want a subset of the fields. By default, GORM will select all fields.
// Select accepts both string arguments and arrays.
//
//	// Select name and age of user using multiple arguments
//	db.Select("name", "age").Find(&users)

Crie um token de acesso JWT real e o retorne.
