Question

我正在尝试通过在redux传奇中调用put方法来触发redux reducer，但是即使我返回了应该在我的reducer中捕获的相同操作类型，它也不会被触发。

这是我的传奇故事

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;
}
}

我希望在控制台中看到“成功注册”，并在组件中获得该响应作为支持，但这不会发生。什么会导致此问题？

这是我的rootReducer，还存储：

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不应是调用combineReducers的函数，而应是combineReducers的返回值：

const rootReducer = combineReducers({
    registrationReducer,
    todoReducer,
});

export default rootReducer;

Redux API

Redux-Saga Put方法不会触发reducer
