Firefox SDK简单存储和Firefox同步 [英] Firefox SDK simple-storage and Firefox Sync

问题描述

我目前正在将Chrome扩展程序转换成Firefox加载项，并希望能够复制chrome.storage.sync功能。

但是，我无法管理使用简单存储将在附加组件的用户登录到 Firefox Sync 。

考虑到通过后一种方法存储的所有数据段在用户个人资料中找到，我认为它会...只要附加功能在 https：// addons .mozilla.org ？

关于这个主题的任何信息将不胜感激。

解决方案

simple-storage 未同步。但是您可以轻松地同步它。

存储存储对象的技巧，它可以被序列化定义为字符串首选项，并告诉同步服务进行同步。

让我们指定首选项 syncstorage 和将其标记为可同步。

  var self = require（sdk / self）; 
 var prefs = require（sdk / preferences / service）; 
 prefs.set（services.sync.prefs.sync.extensions。+ self.id +.syncstorage，true）; 
  

将某些内容存储到 simple-storage 更改为 syncstorage 。

$ b

  var sp = require（sdk / simple-prefs）; 
 var ss = require（sdk / simple-storage）; 
 sp.prefs [syncstorage] = JSON.stringify（ss.storage）; 
  

对于相反的效果，更改 syncstorage
$ b

sp.on（syncstorage，function（prefname）{
ss。 storage = JSON.parse（sp.prefs [syncstorage]）;
}）


最后但并非最不重要的，这将是很好的，也许是强制性的同步只有用户的明确同意。

I'm currently converting a Chrome extension into a Firefox add-on and would appreciate to replicate the chrome.storage.sync feature.

However, I cannot manage to find whether the data stored by a Firefox add-on using simple-storage will be automatically synced whenever a user of the add-on is signed into Firefox Sync.

Given that all the pieces of data stored via the latter method can be found in the user profile, I presume it will... as long as the add-on is available at https://addons.mozilla.org ?

Any information on the topic would be greatly appreciated.

解决方案

simple-storage is not synced. But you can sync it with little effort.

The trick it to store the storage object, it is serializable by definition, as a string preference and tell to the sync service to synchronize it.

Lets name that preference syncstorage and mark it as synchronizable.

var self = require("sdk/self");
var prefs = require("sdk/preferences/service");
prefs.set("services.sync.prefs.sync.extensions." + self.id + ".syncstorage", true);

When storing something to simple-storage reflect the change to syncstorage.

var sp = require("sdk/simple-prefs");
var ss = require("sdk/simple-storage");
sp.prefs["syncstorage"] = JSON.stringify(ss.storage);

For the opposite effect watch syncstorage for changes

sp.on("syncstorage", function(prefname){
  ss.storage = JSON.parse(sp.prefs["syncstorage"]);
})

Last but not least, It would nice and perhaps mandatory to sync only with the explicit consent of the user.
