上面是我写一个动作和一个减缩器的相当粗糙的尝试，它能够将true或false传递到边栏并打开它。我需要帮助，当我的布局中的菜单按钮被点击时，我如何（简单地）告诉redux改变我的侧边栏的状态
感谢您的帮助和指导。
首先，我建议您更换您的
if (action.type === sidebarOpen) {
       someaction..
    } else {
       someaction..
    }

与
在src/store/Stage.js中，当减速器增长足够大时，它将更具可读性
现在，关于您所关心的问题，您当前实现中缺少的步骤是使用reducer映射state/props
请查看以下代码：
const mapStateToProps = state => ({
    myVar: state.myVarFromReducer,
});

const mapDispatchToProps = dispatch => ({
    expandFn: () => expand(dispatch),
});

export default connect(mapStateToProps, mapDispatchToProps)(myComponent);

让我们忽略mapDispatchToProps
，它不会用于我们的关注
我邀请您查看并更好地理解redux和react之间的联系
注意：此代码示例经常出现在组件文件的末尾
我们这里有一个绑定connect（mapStateToProps，…）（myComponent），它与我的组件处于指定状态。
例如，指定的状态是您在src/store/Stage.js中定义的值
因此，在您的情况下，您必须将您的组件与存储连接起来，具体操作方法如上所述。
然后，您必须映射要在组件状态中包含的减速器状态的信息。
它将如下所示：
const mapStateToProps = state => ({
    show: state.show,
});

基本上，这意味着“将组件状态的属性show
与减速器的属性show
绑定”
如果减速器的show
属性发生变化，则会通知该部件，并更新其show
属性。
