在Redux-saga中，如何从对承诺的收益预测中获得结果？

import { fetchData } from './api'; // 替换为实际的异步函数

import { call, put } from 'redux-saga/effects';

function* fetchDataSaga() {
  try {
    const data = yield call(fetchData); // 调用异步函数获取数据
    yield put({ type: 'FETCH_SUCCESS', payload: data }); // 派发成功的action到Redux store中
  } catch (error) {
    yield put({ type: 'FETCH_ERROR', payload: error }); // 派发错误的action到Redux store中
  }
}

import { takeEvery } from 'redux-saga/effects';

function* watchFetchData() {
  yield takeEvery('FETCH_DATA', fetchDataSaga); // 监听FETCH_DATA action，并在触发时执行fetchDataSaga
}

import { all } from 'redux-saga/effects';

function* rootSaga() {
  yield all([
    watchFetchData(), // 添加其他需要监听的watcher saga
  ]);
}

import { createStore, applyMiddleware } from 'redux';
import createSagaMiddleware from 'redux-saga';
import rootReducer from './reducers';
import rootSaga from './sagas';

const sagaMiddleware = createSagaMiddleware();
const store = createStore(rootReducer, applyMiddleware(sagaMiddleware));

sagaMiddleware.run(rootSaga);
