如何在我的react状态下访问此信息？

npm install redux react-redux

// store.js
import { createStore } from 'redux';

const initialState = {
  information: null // 用于存储信息的状态
};

// 定义一个reducer来更新状态
const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'SET_INFORMATION':
      return {
        ...state,
        information: action.payload
      };
    default:
      return state;
  }
};

const store = createStore(reducer);

export default store;

// InformationComponent.js
import React from 'react';
import { connect } from 'react-redux';

const InformationComponent = ({ information }) => {
  return (
    <div>
      <h2>信息</h2>
      <p>{information}</p>
    </div>
  );
};

// 将状态映射到组件的属性
const mapStateToProps = (state) => {
  return {
    information: state.information
  };
};

export default connect(mapStateToProps)(InformationComponent);

import React from 'react';
import InformationComponent from './InformationComponent';

const App = () => {
  return (
    <div>
      <h1>我的应用</h1>
      <InformationComponent />
    </div>
  );
};

export default App;

import React from 'react';
import { connect } from 'react-redux';

const UpdateInformationButton = ({ dispatch }) => {
  const handleClick = () => {
    const information = '这是我的信息';
    dispatch({ type: 'SET_INFORMATION', payload: information });
  };

  return (
    <button onClick={handleClick}>更新信息</button>
  );
};

export default connect()(UpdateInformationButton);
