在redux-saga中,可以通过使用takeLatest
或takeEvery
等effect来监听成功操作,并在成功操作后清除本地状态。
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);
fetchData
的saga,它会在成功操作后清除本地状态。import { takeLatest, put } from 'redux-saga/effects';
import { FETCH_DATA_SUCCESS, CLEAR_LOCAL_STATE } from '../actions/types';
function* clearLocalState() {
// 清除本地状态的逻辑
yield put({ type: CLEAR_LOCAL_STATE });
}
function* fetchDataSaga() {
yield takeLatest(FETCH_DATA_SUCCESS, clearLocalState);
}
export default fetchDataSaga;
fetchDataSaga
添加到根saga中。import { all } from 'redux-saga/effects';
import fetchDataSaga from './fetchDataSaga';
function* rootSaga() {
yield all([
fetchDataSaga(),
// 其他saga...
]);
}
export default rootSaga;
这样,当FETCH_DATA_SUCCESS
操作被触发时,clearLocalState
saga将被调用,从而清除本地状态。
请注意,以上示例中的FETCH_DATA_SUCCESS
和CLEAR_LOCAL_STATE
是示意性的action类型,你需要根据自己的应用程序定义相应的action类型和逻辑。
