在Redux reducer中访问全局状态？

import { createStore } from 'redux';

// 定义初始状态
const initialState = {
  count: 0,
};

// 定义reducer
const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'INCREMENT':
      // 获取全局状态
      const currentState = store.getState();
      console.log(currentState); // 打印当前全局状态

      // 更新状态
      return {
        ...state,
        count: state.count + 1,
      };
    default:
      return state;
  }
};

// 创建Redux store
const store = createStore(reducer);

// dispatch一个action
store.dispatch({ type: 'INCREMENT' });
