IT技术 - combineReducers 导致代码中断 - 吾爱随笔录

这是我在这里发布的线程之后

经过大量故障排除后，我发现此代码可以正常工作

import React from 'react';
import { createStore, combineReducers, applyMiddleware } from 'redux';
import createLogger from 'redux-logger';
import thunkMiddleware from 'redux-thunk';
import { Provider } from 'react-redux';
import DataTableReducer from './reducers/DataTableReducer';
import DimensionPickerReducer from './reducers/DimensionPickerReducer';

const loggerMiddleware = createLogger();
const store = createStore(
    DimensionPickerReducer, 
    applyMiddleware(
        thunkMiddleware, 
        loggerMiddleware
    )
);

export default store;

但是如果我用一个像这样的组合减速器调用替换我的单个减速器

import React from 'react';
import { createStore, combineReducers, applyMiddleware } from 'redux';
import createLogger from 'redux-logger';
import thunkMiddleware from 'redux-thunk';
import { Provider } from 'react-redux';
import DataTableReducer from './reducers/DataTableReducer';
import DimensionPickerReducer from './reducers/DimensionPickerReducer';

const loggerMiddleware = createLogger();
const store = createStore(
    combineReducers({
        DataTableReducer,
        DimensionPickerReducer
    }), 
    applyMiddleware(
        thunkMiddleware, 
        loggerMiddleware
    )
);

export default store;

我立即开始收到 DimensionPicker 控件的错误，即未指定强制props。

所以 combineReducer 方法对我不起作用。

我在这里上传了一个示例项目，它显示了问题。
