@Post('/login')
  async login(@Body() request: AuthenticateRequest, @Res() res: Response) {
    const userByEmail = await this.userService.getByEmail(request.email);
    const accessToken = await this.authService.getAccessToken(
      userByEmail.email,
    );
    // 쿠키를 Authorization 에 박는 방법
    res.setHeader('Authorization', 'Bearer ' + accessToken);
    
    // Cookie 의 이름을 jwt라 한다.
    res.cookie('jwt', accessToken, {
      httpOnly: true,
      maxAge: 24 * 60 * 60 * 1000,	// 1day
    });
