Redux 即使达到类型也不保存状态 [已解决]

Question

更新：我想我发现了我的问题，我以某种方式通过 useSelector(state => state.auth) 访问了我的状态，但它没有保存我的 ordersReducer。

请帮助我。我有这个代码，我已经达到了

SAVE_ORDERS_SUCCESS

，但它没有保存它的状态。这是我的代码。仅供参考，我有另一个减速器来更新身份验证并且它有效。

我的电话

dispatch(getOrdersList())
    .then(() => console.log('save'))
    .catch(err => console.log('eeeS'));

api调用

const getOrdersList = (data = {}) => {
  const url = `get_all_order`;
  const user = JSON.parse(localStorage.getItem('user'));

  const headers = {
    access_token: user.data.token
  };

  const body = {
    ...data,
    type: data.admin_id ? null : 'super'
  };

  return apiCall(url, body, headers).then(response => response);
};

export default {
  getOrdersList
};

我的减速器

import {
  SAVE_ORDERS_SUCCESS,
  SAVE_ORDERS_FAILURE,
  GETTING_DATA
} from 'actions/types';

const initialState = {
  ordersData: null,
  isLoading: false,
  error: null
};

export default function (state = initialState, action) {
  const { type, payload } = action;
  console.log('🚀 ~ file: getOrdersReducer.js:15 ~ payload:', payload);

  switch (type) {
    case GETTING_DATA:
      return { ...state, isLoading: true, error: null };
    case SAVE_ORDERS_SUCCESS:
      return { ...state, isLoading: false, ordersData: payload.response };
    case SAVE_ORDERS_FAILURE:
      return { ...state, isLoading: false, error: action.payload };
    default:
      return state;
  }
}

结合

import { combineReducers } from 'redux';
import auth from './auth';
import message from './message';
import getOrdersReducer from './getOrdersReducer';

export default combineReducers({
  getOrdersReducer,
  auth,
  message
});

类型和存储

export const GETTING_DATA = 'GETTING_DATA';
export const SET_MESSAGE = 'SET_MESSAGE';
export const CLEAR_MESSAGE = 'CLEAR_MESSAGE';

export const SAVE_ORDERS_SUCCESS = 'SAVE_ORDERS_SUCCESS';
export const SAVE_ORDERS_FAILURE = 'SAVE_ORDERS_FAILURE';

import { legacy_createStore as createStore, applyMiddleware } from 'redux';
import { composeWithDevTools } from 'redux-devtools-extension';
import thunk from 'redux-thunk';
import rootReducer from './reducers';

const middleware = [thunk];

const store = createStore(
  rootReducer,
  composeWithDevTools(applyMiddleware(...middleware))
);

export default store;

我试过 console.log

payload

以防万一

SAVE_ORDERS_SUCCESS

仍然看到它，但退货不会保存在商店中。

Answer 1

你不会返回一个 action 与

getOrdersList

函数只是响应。

dispatch

期望这是一个具有类型和有效载荷的对象

const { type, payload } = action;

而是只收到

response

const getOrdersList = (data = {}) => {
  // ...

  return apiCall(url, body, headers).then((response) => response);
};

由于减速器没有接收到

type

，它将回退到

default

并返回

state

。你可以通过这样做来解决这个问题：

const getOrdersList = (data = {}) => {
  // ...

  const data = apiCall(url, body, headers).then((response) => response);

  return {
    type: SAVE_ORDERS_SUCCESS,
    payload: data,
  };
};
