Question

这是我的减速机工作得很好：

    const rootReducer   =   createStoreWithMiddleware(combineReducers({
        companies: companies,
        brands: brands,
        login: login,
        chat: chat,
        banners: banners,
        sessions: sessions,
        settings: settings,
        statistics: statistics
}));

我希望我的系统是模块化的，所以我尝试将其更改为：

    const rootReducer   =   createStoreWithMiddleware(combineReducers({
    chatModule: {
        companies: companies,
        brands: brands,
        login: login,
        chat: chat,
        banners: banners,
        sessions: sessions,
        settings: settings,
        statistics: statistics
    }
}));

然后我在浏览器中收到此错误：

Store does not have a valid reducer. Make sure the argument passed to combineReducers is an object whose values are reducers.

这是整个文件代码：

    import {combineReducers, createStore, applyMiddleware} from 'redux';
import ReduxPromise from 'redux-promise';
import {login, chat, chatClick, banners, sessions, companies, settings, statistics, brands} from '../actions/actions'

const createStoreWithMiddleware =   applyMiddleware(ReduxPromise)(createStore);

const rootReducer   =   createStoreWithMiddleware(combineReducers({
    chatModule: {
        companies: companies,
        brands: brands,
        login: login,
        chat: chat,
        banners: banners,
        sessions: sessions,
        settings: settings,
        statistics: statistics
    }
}));

export default rootReducer;

公司，品牌，登录等......出口功能......

正如错误消息中所述，您应该转到值为 reducers 的combineReducers对象。您传递了一个值为对象（{companies: companies,brands: brands, ...}）

的对象

combineReducers会返回reducer本身，所以你可以这样做：

const rootReducer = createStoreWithMiddleware(combineReducers({
  chatModule: combineReducers({
    companies: companies,
    brands: brands,
    login: login,
    chat: chat,
    banners: banners,
    sessions: sessions,
    settings: settings,
    statistics: statistics
  })
})

商店没有有效的减速机。确保传递给combineReducers的参数是一个值为reducers的对象
