我正在调用操作requestLoadOrders
来获取我需要的订单。我发送的是REQUEST
类型,之后是SUCCESS
或FAILURE
。获取成功是因为我的订单位于redux dev-tools的有效负载中,但我在reducer中收到的操作是@@redux/PROBE_UNKNOWN_ACTION_z.r.p.l.z
。我找到了关于这个here的帖子,但我似乎无法找到我做错的事情?
actions.js
import {
LOAD_ORDERS_REQUEST,
LOAD_ORDERS_SUCCESS,
LOAD_ORDERS_FAILURE
} from './constants';
import { fetchOrders } from '../../api';
export const requestLoadOrders = () => {
return (dispatch, getState) => {
dispatch({ type: LOAD_ORDERS_REQUEST });
fetchOrders().then(orders => {
dispatch({ type: LOAD_ORDERS_SUCCESS, payload: orders});
}).catch(error => {
console.error(error);
dispatch({ type: LOAD_ORDERS_FAILURE, payload: error});
});
};
};
reducer.js
import {
LOAD_ORDERS_REQUEST,
LOAD_ORDERS_SUCCESS,
LOAD_ORDERS_FAILURE
} from './constants';
const initialState = {
orders: []
};
const orderReducer = ( state = initialState, { payload, type }) => {
switch (type) {
case LOAD_ORDERS_REQUEST :
return state;
case LOAD_ORDERS_SUCCESS :
return { ...state, orders: payload};
case LOAD_ORDERS_FAILURE :
return { ...state, error: payload.error};
default :
return state;
}
};
export default orderReducer;
我的操作得到正确发送,但我认为reducer接收数据时出现问题。因此,我还添加了我的商店和合并缩减器文件。
store.js
import { createStore, applyMiddleware, compose } from 'redux';
import { routerMiddleware } from 'react-router-redux';
import createHistory from 'history/createBrowserHistory';
import thunk from 'redux-thunk';
import makeRootReducer from './reducers';
export const history = createHistory();
const initialState = {}
const enhancers = [];
const middleware = [ routerMiddleware(history), thunk ];
if (process.env.NODE_ENV === 'development') {
const devToolsExtension = window.devToolsExtension;
if (typeof devToolsExtension === 'function') {
enhancers.push(devToolsExtension());
}
}
const composedEnhancers = compose(
applyMiddleware(...middleware),
...enhancers
);
const store = createStore(
makeRootReducer,
initialState,
composedEnhancers
);
export default store;
reducers.js
import { combineReducers } from 'redux';
import orderReducer from '../modules/Order/reducer';
export const makeRootReducer = asyncReducers => {
return combineReducers({
order: orderReducer,
...asyncReducers
});
}
export default makeRootReducer;
答案 0 :(得分:0)
我发现了自己的错误。我应该通过在createStore()中的单词后添加括号来执行makeRootReducer函数。
将 store.js 的createStore()部分更新为:
const store = createStore(
makeRootReducer(),
initialState,
composedEnhancers
);
是修复。
