跨单个应用程序信息亭模式执行持久化数据

问题描述

在开发普通的Chrome应用时，我使用 Chrome存储API 来保留键值对跨会话.这很好用，我想对单应用信息亭模式执行相同的操作要在托管的Chrome设备上部署的应用程序.但是，chrome.storage.local似乎并没有在应用程序的整个执行过程中持续存在.

When developing normal Chrome Apps, I use the Chrome storage API to persist key-value pairs across sessions. This works great, and I want to do the same for a Single App Kiosk Mode app to be deployed on managed Chrome devices. However, it seems that chrome.storage.local does not persist across executions of the app.

我写了一个测试应用来说明此问题.代码此处.

I wrote a test app illustrating this issue. Code here.

推荐答案

注意:此答案仅适用于Chrome管理控制台的用户

事实证明，问题与Chrome管理控制台中的设置有关.在设备设置下，用户数据"选项应为不清除所有本地用户数据".我已将其设置为擦除所有本地用户数据"，这在每次重新启动时都会擦除我的localStorage.我没有仔细查看该选项，因为我发现Single App Kiosk Mode存在于用户会话之外，因此没有要删除的用户数据.

It turns out the issue had everything to do with a setting in the Chrome Management Console. Under Device Settings, the "User Data" option should be "Do not erase all local user data." I had set it to "Erase all local user data," which wiped out my localStorage with each reboot. I didn't look at that option closely since I figured Single App Kiosk Mode existed outside of a user session, so there was no user data to erase.
