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;
