如何调用redux saga生成器函数？

// 引入必要的依赖
import { createStore, applyMiddleware } from 'redux';
import createSagaMiddleware from 'redux-saga';
import { takeEvery, put } from 'redux-saga/effects';

// 创建Saga生成器函数
function* fetchDataSaga(action) {
  try {
    // 执行异步操作，例如发送网络请求
    const response = yield fetch('https://api.example.com/data');
    const data = yield response.json();

    // 将获取到的数据存储到Redux Store中
    yield put({ type: 'FETCH_SUCCESS', payload: data });
  } catch (error) {
    // 处理错误情况
    yield put({ type: 'FETCH_ERROR', error });
  }
}

// 创建Saga监听器
function* watchFetchData() {
  yield takeEvery('FETCH_DATA', fetchDataSaga);
}

// 创建Redux Store并应用Saga中间件
const sagaMiddleware = createSagaMiddleware();
const store = createStore(reducer, applyMiddleware(sagaMiddleware));

// 启动Saga监听器
sagaMiddleware.run(watchFetchData);
