Angular “缺少Redux状态”；“离线”；来自redux脱机的部分

我在Angular项目中使用，现在我想在脱机模式下取消发件箱中的项目。基本上，我只想在发件箱阵列上进行筛选，以删除我要取消/修改的项目

我的问题是，我在顶级减速器中收到的状态缺少（未定义）。我可以在Redux开发工具中看到离线，也可以通过NgRedux.select（）和NgRedux.getState（）获得离线

redux offline在减速器中接收到的状态下不存在的原因是什么？我可以添加它，然后通过减速机更改它吗？或者是否有其他用户可以访问和修改发件箱

redux offline

动态注入它自己的reducer，因此您将无法通过顶级reducer访问它

redux offline

通过配置公开它，该配置允许您更新发件箱以删除/添加操作。如果您想在用户脱机时删除脱机操作，我建议使用特定操作类型（例如，

“取消脱机操作”

）进行脱机操作调用，并在

队列中处理。排队

删除发件箱中您不想传播的操作

下面是一个粗略的例子：

//要分派的操作
常量动作={
键入：“取消脱机操作”，
有效载荷：{
id:123，
},
元：{
离线：{
效果：{
url:“”
},
},
},
};
//自定义排队操作
功能排队（发件箱、收件操作）{
return incomingAction.type！=“取消脱机操作”？[…发件箱，incomingAction]：
发件箱过滤器(
outboxAction=>outboxAction.payload.id！==incomingAction.payload.id，
);
}
