如何使用Redux在前端实现身份验证？

import { createStore } from 'redux';
import rootReducer from './reducers'; // 这里的reducers是一个文件夹，包含所有的reducer

const store = createStore(rootReducer);

// actions.js
export const login = (username, password) => ({
  type: 'LOGIN',
  payload: { username, password },
});

export const logout = () => ({
  type: 'LOGOUT',
});

// authReducer.js
const initialState = {
  isAuthenticated: false,
  user: null,
};

const authReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'LOGIN':
      // 执行登录逻辑，比如调用API验证用户身份
      return {
        isAuthenticated: true,
        user: action.payload.username,
      };
    case 'LOGOUT':
      // 执行注销逻辑
      return {
        isAuthenticated: false,
        user: null,
      };
    default:
      return state;
  }
};

export default authReducer;

// reducers/index.js
import { combineReducers } from 'redux';
import authReducer from './authReducer';

const rootReducer = combineReducers({
  auth: authReducer,
  // 其他reducer
});

export default rootReducer;

import { connect } from 'react-redux';
import { login, logout } from './actions';

const MyComponent = ({ isAuthenticated, user, login, logout }) => {
  // 使用身份验证状态和操作
};

const mapStateToProps = (state) => ({
  isAuthenticated: state.auth.isAuthenticated,
  user: state.auth.user,
});

const mapDispatchToProps = {
  login,
  logout,
};

export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);
