其实有好几个问，卡了好久了不知道什么原因
1.两个reducer的state都有值的情况下
store.subscribe(() => {

console.log("================监听store变化："+JSON.stringify(store));

});
打印的值一直是空的{}。

2.点击导航时候在Mount组件的时候去请求数据，然后执行store.dispatch(initUserAction(res))，初始化reducer的state，state有数据，但是store.subscribe里面答应的store一直是空的。
这个是加载组件的时候初始化的代码

componentWillMount(){
        const {store} = this.context;
        fetch("http://localhost:3001/book")
        .then(res => res.json())
        .then(res => {
            store.dispatch(initBookAction(res));
        });
    }

这个是reducer的代码

const initialState = {
    data : []
};

function bookReducer(state=initialState ,action){
    switch(action.type){
        case 'INIT_BOOK_ACTION':
            console.log("=====初始化bookReducer:"+JSON.stringify(state));
            return Object.assign({},state,{
                data : [...action.payload]
            })

        case 'ADD_BOOK_ACTION' : 
            return Object.assign({},state,{
                data : state.data.push(action.payload)
            })

        case 'DELETE_BOOK_ACTION' :
            return Object.assign({},state,{
                data : state.data.filter(item => item.id != action.payload.id)
            })

        case 'UPDATE_BOOK_ACTION' :
            return Object.assign({},state,{
                data : state.data.map(item => {
                    if(item.id == action.payload.id){
                        return Object.assign({},item,action.payload);
                    }else{
                        return item;
                    }
                })
            })
        default:
            return state
    }
}

export default bookReducer;

3.我加载的table的数据是mapStateToProps传递过来的数据，既然store为空，为什么container组件中给mapStateToProps传递的state依然可以取到数据state.bookReducer.date,然后在table中展示出来数据呢？

这个是render table的主要代码

render(){
        const { bookList, deleteBook } = this.props; //connect传递的props
        const { title,visible ,confirmLoading } = this.state;
        //console.log("===================booklist props:"+JSON.stringify(this.props));
        
        const columns = [{
            title : '图书编号',
            dataIndex : 'id'
        },{
            title : '名称',
            dataIndex : 'name'
        },{
            title:'价格',
            dataIndex:'price'
        },{
            title:'借阅人编号',
            dataIndex:'owner_id'
        },{
            title:'操作',
            render : (text,record) => (
                <span type="ghost">
                    <Button size="small" onClick={() => this.editHandle(record)}>编辑</Button>
                    <Divider type="vertical" />
                    <Popconfirm title="确定要删除吗？" onConfirm={() => deleteBook(record)}>
                        <Button size="small" >删除</Button>
                    </Popconfirm>
                </span>
            )
        }];

        return (
            <div>
                <div>
                    <SearchInput addHandle={this.addHandle.bind(this)}/>
                </div>
                <Table columns={columns} dataSource={bookList}/>
                <Modal 
                    title={title}
                    visible= {visible}
                    confirmLoading = {confirmLoading}
                    onCancel = {() => this.cancelHandle()}
                    footer = {null}
                >
                    <FormLayout record={this.state.formData} comfirmHandle={this.comfirmHandle.bind(this)}/>
                </Modal>
            </div>
        );
    }

这个是创建container组件的代码

import { connect } from 'react-redux';
import BookList from '../components/BookList';
import { deleteBookAction , addBookAction ,updateBookAction } from '../actions/bookActions';

const mapStateToProps = (state) => {
    return {
        bookList : state.bookReducer.data
    };
}

const mapDispatchToProps = (dispatch) => {
    return {
        deleteBook : (id) => {
            dispatch(deleteBookAction(id))
        },
        addBook : (data) => {
            dispatch(addBookAction(data))
        },
        editBook : (data) => {
            dispatch(updateBookAction(data))
        }
    }
}
const BookListContainer = connect(
    mapStateToProps,
    mapDispatchToProps
)(BookList);

export default BookListContainer;

代码有点多我把github地址粘上来，麻烦各位大神帮我看一下，谢谢~
