Redux-saga put 方法不会触发减速器

Question

我试图通过在我的 redux saga 中调用 put 方法来触发 redux reducer，但它没有被触发，即使我返回应该在我的 reducer 中捕获的相同操作类型。这是我的传奇：export function* registrationSaga(action) {  try {    const response = yield call(registerUser, action.payload);    console.log(response)    yield put({ type: REGISTER_USER_SUCCESS, response })  } catch(error) {    yield put({ type: REGISTER_USER_ERROR, error });  }}这是我的减速器：export const registrationReducer = (state = {}, action) => {let response = action.response;switch(action.type) {  case REGISTER_USER_SUCCESS: {    console.log("successful registration")    return { ...state, registration_success: response.success, registration_message: response.message };  }  case REGISTER_USER_ERROR:    return { ...state, registration_success: response.success, registration_message: response.message };  default:    return state;}}我希望在我的控制台中看到“成功注册”并在我的组件中将该响应作为道具获得，但这并没有发生。什么应该导致这个问题？这是我的 rootReducer 和商店：const rootReducer = () => combineReducers({    registrationReducer,    todoReducer})export default rootReducer;并存储：const sagaMiddleware = createSagaMiddleware()export const store = createStore(    rootReducer,    applyMiddleware(sagaMiddleware));sagaMiddleware.run(rootSaga)

rootReducer不应该是调用的函数combineReducers，而应该是以下的返回值combineReducers：

const rootReducer = combineReducers({

    registrationReducer,

    todoReducer,

});

export default rootReducer;
