React Redux未更新状态，尽管登录工作正常

import { loginSuccess } from './actions';

// 登录成功后的回调函数
const handleLoginSuccess = (response) => {
  // 更新状态
  dispatch(loginSuccess(response.data));
};

import { LOGIN_SUCCESS } from './actionTypes';

const initialState = {
  isLoggedIn: false,
  user: null,
};

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case LOGIN_SUCCESS:
      return {
        ...state,
        isLoggedIn: true,
        user: action.payload,
      };
    // 其他case语句...
    default:
      return state;
  }
};

import { connect } from 'react-redux';

const MyComponent = ({ isLoggedIn, user }) => {
  // 组件的渲染逻辑...
};

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

export default connect(mapStateToProps)(MyComponent);

import React, { useState } from 'react';

const MyComponent = () => {
  const [isLoggedIn, setIsLoggedIn] = useState(false);
  const [user, setUser] = useState(null);

  // 登录成功后的回调函数
  const handleLoginSuccess = (response) => {
    // 更新组件状态
    setIsLoggedIn(true);
    setUser(response.data);
  };

  // 组件的渲染逻辑...
};
