如何在ReactReduxContext.Consumer中订阅更新？

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

class MyComponent extends React.Component {
  render() {
    return (
      <ReactReduxContext.Consumer>
        {({ store }) => {
          // 在这里访问store并订阅更新
          return <div>{/* 渲染内容 */}</div>;
        }}
      </ReactReduxContext.Consumer>
    );
  }
}

class MyComponent extends React.Component {
  componentDidMount() {
    const { store } = this.context;
    // 订阅更新
    this.unsubscribe = store.subscribe(() => {
      // 更新组件状态或执行其他操作
    });
  }

  componentWillUnmount() {
    // 取消订阅
    this.unsubscribe();
  }

  render() {
    return (
      <ReactReduxContext.Consumer>
        {({ store }) => {
          // 渲染内容
          return <div>{/* 渲染内容 */}</div>;
        }}
      </ReactReduxContext.Consumer>
    );
  }
}

MyComponent.contextType = ReactReduxContext;
