### Question:
GatewayApiController { @PostMapping("/delete.json") public Result<Long> deleteApi(HttpServletRequest request, Long id) { AuthService.AuthUser authUser = authService.getAuthUser(request); if (id == null) { return Result.ofFail(-1, "id can't be null"); } ApiDefinitionEntity oldEntity = repository.findById(id); if (oldEntity == null) { return Result.ofSuccess(null); } authUser.authTarget(oldEntity.getApp(), AuthService.PrivilegeType.DELETE_RULE); try { repository.delete(id); } catch (Throwable throwable) { logger.error("delete gateway api error:", throwable); return Result.ofThrowable(-1, throwable); } if (!publishApis(oldEntity.getApp(), oldEntity.getIp(), oldEntity.getPort())) { logger.warn("publish gateway apis fail after delete"); } return Result.ofSuccess(id); }  @GetMapping("/list.json") Result<List<ApiDefinitionEntity>> queryApis(HttpServletRequest request, String app, String ip, Integer port); @PostMapping("/new.json") Result<ApiDefinitionEntity> addApi(HttpServletRequest request, @RequestBody AddApiReqVo reqVo); @PostMapping("/save.json") Result<ApiDefinitionEntity> updateApi(HttpServletRequest request, @RequestBody UpdateApiReqVo reqVo); @PostMapping("/delete.json") Result<Long> deleteApi(HttpServletRequest request, Long id);  }### Answer:
