我在我的 Angular 项目中使用 Redux Offline，现在我想在离线模式下取消发件箱中的项目。基本上，我只想过滤发件箱数组以删除要取消/修改的项目。
我的问题是我在顶级化简器中收到的状态中缺少(未定义(。我可以在Redux Dev工具中离线查看，也可以通过NgRedux.select((和NgRedux.getState((获取它。
是否有原因导致 redux 脱机在化简器中收到的状态中不存在？我可以添加它，然后通过化简器更改它吗？还是有其他人可以访问和修改发件箱？

如果您需要更多信息，请写评论。
redux-offline动态注入它自己的化简器，因此您将无法通过顶级化简器访问它。redux-offline通过配置公开其队列，这将允许您更新发件箱以删除/添加操作。如果您想在用户离线时删除离线操作，我建议您使用特定操作类型进行离线操作调用(例如'CANCEL_OFFLINE_ACTION'(，并在queue.enqueue中处理它，以删除发件箱中您不想传播的操作。
下面是一个粗略的示例：
// the action to dispatch
const action = {
type: 'CANCEL_OFFLINE_ACTION',
payload: {
id: 123,
},
meta: {
offline: {
effect: {
url: ''
},
},
},
};
// the custom enqueue action
function enqueue(outbox, incomingAction) {
return incomingAction.type !== 'CANCEL_OFFLINE_ACTION' ? [...outbox, incomingAction] :
outbox.filter(
outboxAction => outboxAction.payload.id !== incomingAction.payload.id,
);
}
