    @PostMapping("/auth")
    public ApiResponse<PassportTokenVo> auth(@Validated @RequestBody PassportAuthDto passportAuthDto)
    {
        PassportTokenVo passportTokenVo = adminService.passport(passportAuthDto);
        return ApiResponse.success(ResponseCodeEnum.SUCCESS.getCode(), "登录成功", passportTokenVo);
    }
