HTML5 数据库和 localStorage 可以跨子域共享吗? [英] Can HTML5 databases and localStorage be shared across subdomains?

问题描述

我正在尝试使用 Safari 跨子域共享数据.我想使用 HTML5 数据库(特别是 localStorage 因为我的数据只是键值对).但是，似乎无法从 sub.domain.com 访问存储到 domain.com 的数据(反之亦然).这种情况有没有办法共享一个数据库?

I am attempting to share data across subdomains using Safari. I would like to use an HTML5 database (specifically localStorage as my data is nothing but key-value pairs). However, it seems as though data stored to domain.com can not be accessed from sub.domain.com (or vice versa). Is there any way to share a single database in this situation?

这个来自 Zendesk 的图书馆对我有用.

示例:

中心

// Config s.t. subdomains can get, but only the root domain can set and del
CrossStorageHub.init([
  {origin: /.example.com$/,            allow: ['get']},
  {origin: /://(www.)?example.com$/, allow: ['get', 'set', 'del']}
]);

注意 $ 用于匹配字符串的结尾.上面示例中的正则表达式将匹配诸如 valid.example.com 之类的源，但不会匹配 invalid.example.com.malicious.com.

Note the $ for matching the end of the string. The regular expression in the above example will match origins such as valid.example.com, but not invalid.example.com.malicious.com.

客户

var storage = new CrossStorageClient('https://store.example.com/hub.html');

storage.onConnect().then(function() {
  return storage.set('newKey', 'foobar');
}).then(function() {
  return storage.get('existingKey', 'newKey');
}).then(function(res) {
  console.log(res.length); // 2
}).catch(function(err) {
  // Handle error
});
