Redux状态未更新问题。但是redux logger会显示正确的操作和下一个状态更新

Question

我正在将Redux用于我的Web应用程序。用户登录后必须更新状态。 Redux记录器用于调试。在redux logger中一切正常，但状态未更新。请提供有关此问题的任何想法。

减速器：

import { adminConstants } from '../Admin/admin.constants.js';

export function adminReducers(state={},action)
{
  switch (action.type) {
    case adminConstants.ADMIN_LOGIN_REQUEST:
      return {
        loggingIn: true,
        };
    case adminConstants.ADMIN_LOGIN_SUCCESS:
      return {
          loggedIn: true,
          admin:action.admin
      };
    case adminConstants.ADMIN_LOGIN_FAILURE:
      return {};
    case adminConstants.ADMIN_LOGOUT:
      return {};
    default:
      return state;
    }
}

组合还原剂：

const rootReducer = combineReducers({
  authentication,
  registration,
  users,
  alert,
  adminReducers
});

export default rootReducer;

mapStateToProps ：（在此控制台中，所有对象的日志均显示为空）

function mapStateToProps(state) {
    console.log("state "+ JSON.stringify(state));

    const {  adminReducers } = state;
    const { admin } = adminReducers;
    return {
           admin
    };
}
const connectedAdminPanel = connect(mapStateToProps)(AdminPanel);
export { connectedAdminPanel as AdminPanel };

登录页面后的访问状态为，但对于adminReducers则显示为空：

Redux记录器：（显示处于状态的adminReducers已更新）
