在slices redux工具包之间共享状态？

Question

任何想法如何将状态数据从一个切片传递到另一个切片，换句话说，切片B可以访问slice A ...它尝试在另一个切片中使用getState（），但是它会导致参考错误，什么是正确解决这个问题吗？

// Slice A 
import { createSlice, PayloadAction } from '@reduxjs/toolkit';
import { RootState } from './store';

type userType = { user: ''} 

export interface globalState {
  currentUser: userType;
}

const initialState: globalState = {
  currentUser: { user: '' },
};

export const globalSlice = createSlice({
  name: 'global',
  initialState,
  reducers: {
    setUser: (state, action: PayloadAction<{ user: string }>) => {
      state.currentUser = { user: action.payload.user }
    },
  },
});

export const GlobalCurrentState = (state: RootState) => state.global;
export const { setUser} = globalSlice.actions;

export default globalSlice.reducer;

// Slice B
import { RootState, store } from './store';
import { createSlice, PayloadAction } from '@reduxjs/toolkit';

export interface infoState {
  info: { data: string };

}

const initialState: infoState = {
  info: { data : '' },
};

export const infoSlice = createSlice({
  name: 'info',
  initialState,
  reducers: {
    addName: (state, action: PayloadAction<{ select: string; value: string }>) => {
      const updateData = async () => {
      // this line is casuing a refrence erorr the slice cannot see the info form the other slice. 
      let fromStateA = store.getState().currentUser
    },
});

// Values
export const infoCurrentState = (state: RootState) => state.info;
// Action creators are generated for each case reducer function
export const { addName } = infoSlice.actions;
export default infoSlice.reducer;

这是不打算的，也不可能 - Redux中的切片彼此独立，除了自己的状态和所传递的动作内容外，世界上一无所知。您可以尝试某种自定义的手写还原器，或像降低 - 还原器之类的库，但是大多数情况下，您要么将逻辑分为一片，要么将其分为两部分，或者您不会将足够的信息传递到操作中。
