当用户再次选择页面时，我想在redux saga store中显示保存的数据

// Saga
import { takeLatest, put } from 'redux-saga/effects';
import { SAVE_DATA, SET_DATA } from './actions';

function* saveDataSaga(action) {
  // 保存数据到Redux的store中
  yield put({ type: SET_DATA, payload: action.payload });
}

function* rootSaga() {
  yield takeLatest(SAVE_DATA, saveDataSaga);
}

export default rootSaga;

// Reducer
import { SET_DATA } from './actions';

const initialState = {
  savedData: null,
};

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case SET_DATA:
      return {
        ...state,
        savedData: action.payload,
      };
    default:
      return state;
  }
};

export default reducer;

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

const MyComponent = ({ savedData }) => {
  return (
    <div>
      {/* 在这里使用保存的数据 */}
      {savedData && <p>{savedData}</p>}
    </div>
  );
};

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

export default connect(mapStateToProps)(MyComponent);
