将Google Analytics(分析)Cookie转换为本地/会话存储 [英] Convert Google Analytics cookies to Local/Session Storage
问题描述

Google Analytics(分析)会设置4个Cookie,并设置其子域)。从我可以告诉没有服务器实际使用它们直接;它们只会以 __ utm.gif
作为查询参数发送。
现在,Google Analytics并对它们的值进行操作,并且它们将需要提供给GA跟踪脚本。
所以,我想知道的是,如果可能:
$ c$ b
- 在
ga.js后将
__ utm *
/ code>已在 - 重新开始
下执行 li>在
ga.js
之前,将本地存储的Cookie重写为cookie表单 或者,猴子补丁 ga.js
在开始使用本地存储之前使用本地存储
显然,如果我们走得太远,可以移除 __ utm *
cookies,我们也希望使用Google Analytics(分析)的Async变体。
我猜想下投票是因为我没有提出问题。 DOH!
我的问题是:
可以如上所述完成吗?
如果是,
使用此:
(function(i,s,o,g,r,a,m){i [ 'GoogleAnalyticsObject'] = r; i [r] = i [r] || function(){
(i [r] .q = i [r] .q || [ (0); a.async = 1; a.src = 0; a = s.createElement(o),
m = s.getElementsByTagName(o) g; m.parentNode.insertBefore(a,m)
})(window,document,'script','// www.google-analytics.com/analytics.js','ga');
if(window.localStorage){
ga('create','UA-98765432-1','www.example.com',{
'storage': 'none'
,'clientId':window.localStorage.getItem('ga_clientId')
});
ga(function(tracker){
window.localStorage.setItem('ga_clientId',tracker.get('clientId'));
});
}
else {
ga('create','UA-98765432-1','www.example.com');
}
ga('send','pageview');
首先,检查 localStorage
。如果支持,则'storage':'none'
选项将禁用Cookie。现在我们可以从localStorage设置clientId。如果为空,Google Analytics(分析)会为我们生成一个新的。
如果不支持 localStorage
,则会将新的(或现有的)clientid保存在localStorage中。我只是使用常规的分析方法。初始化后,我通过 ga('send','pageView')
发送pageView。

UPDATE http://jsfiddle.net/musicisair/rsKtp/embedded/result/
Google Analytics sets 4 cookies that will be sent with all requests to that domain (and ofset its subdomains). From what I can tell no server actually uses them directly; they're only sent with __utm.gif
as a query param.
Now, obviously Google Analytics reads, writes and acts on their values and they will need to be available to the GA tracking script.
So, what I am wondering is if it is possible to:
- rewrite the
__utm*
cookies to local storage afterga.js
has written them - delete them after
ga.js
has run - rewrite the cookies FROM local storage back to cookie form right before
ga.js
reads them - start over
Or, monkey patch ga.js
to use local storage before it begins the cookie read/write part.
Obviously if we are going so far out of the way to remove the __utm*
cookies we'll want to also use the Async variant of Analytics.
I'm guessing the down vote was because I didn't ask a question. DOH!
My questions are:
Can it be done as described above?
If so, why hasn't it been done?
I have a default HTML/CSS/JS
boilerplate template that passes YSlow, PageSpeed, and Chrome's Audit with near perfect scores. I'm really looking for a way to squeeze those remaining cookie bytes from Google Analytics in browsers that support local storage.
Use this:
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
if(window.localStorage) {
ga('create', 'UA-98765432-1', 'www.example.com', {
'storage': 'none'
, 'clientId': window.localStorage.getItem('ga_clientId')
});
ga(function(tracker) {
window.localStorage.setItem('ga_clientId', tracker.get('clientId'));
});
}
else {
ga('create', 'UA-98765432-1', 'www.example.com');
}
ga('send', 'pageview');
First, I check if localStorage
is supported. If it is supported then the 'storage': 'none'
option will disable cookies. Now we can set the clientId from localStorage. If it is empty, Google Analytics will generate a new one for us. We save the new (or existing) clientid in localStorage after the tracker loads.
If localStorage
is not supported, I just use the regular analytics method. After the initialization I send a pageView via ga('send', 'pageView')
.
