在Chrome jQuery的AJAX随机误差仅误差、Chrome、jQuery、AJAX
的问题摘要
通过窗体身份验证登录Chrome浏览器之后。着陆页面RETURNURL会报错我jQuery的AJAX没有击中服务器。该状态code = 0 和消息=错误。 （几乎没有有用）。尝试过Firefox和不能够复制的问题，我开始认为Chrome是问题。清除缓存，关闭并重新打开不能解决。最近的文章中，我能找到的就是这个。 jQuery的阿贾克斯 - 状态code 0
然而，URL是相对的， /测试
After logging in with Chrome via Forms Authentication. The landing page as returnUrl will error my jQuery ajax without hitting the server. The status code = 0 and the message = "error". (Hardly useful). Having tried Firefox and not being able to replicate the problem, I am starting to think Chrome is the issue. Clearing caches, closing and reopening does not fix. The closest article i can find is this. jQuery Ajax - Status Code 0?
However, the URL is relative, /Test

较长的描述
我正在使用jQuery阿贾克斯错误。它与窗体身份验证登录后立即看来，登陆页面（RETURNURL），将JS错误。然后刷新页面（F5）后，该脚本将工作（主要）。即使不使用F 5，使用链接将允许对JS工作（主要）导航到相同的页面。所以后直接登录是我的主要测试的路径。
I am getting an error with jQuery ajax. It seems that immediately after logging in with forms authentication; the landing page (returnUrl), will JS error. Then after refreshing the page (F5), the script will work (mostly). Even if not using F5, navigating to the same page using a link will allow the JS to work (mostly). So straight after login is my main testing path.
此外，航行于另一个选项卡 /测试直接行动，有效。最初的标签还是错误，直到我浏览或刷新它提到的。
Also, navigating in another tab to /Test action directly, works. The original tab still errors until i navigate or refresh it as mentioned.
我有次在那里航行或F5刷新不停止的错误。因此在开始段落中使用多数。
I have had times where the navigating or f5 refresh does not stop the error. Thus the use of "mostly" in the opening paragraph.
一天有点不能够找到一个坚实的理由通过研究，JS调试器中，code和各种方案简化后;我需要请求一些帮助。
After a day and a bit of not being able to find a solid reason through research, JS debugger, simplification of code and various scenarios; I need to request some help.
JavaScript错误反馈
最我所知是0 和错误错误的信息。
The most I can gather is a status code of 0 and an error message of "error".
软件和版本
ASP.NET MVC 3
Chrome v28.0.1500.72 m
jQuery v1.8.3
AttributeRouting
使用浏览器，我也曾尝试清空缓存和CTRL + F5。
With Chrome, I have also tried emptying the cache and CTRL+F5.
MVC
我有由保护的作用[授权（角色=管理员）] 禁用这个属性确实出现了解决我的问题，然后后来，没有。因此，如果任何先前的发言弄得不好意思。大声笑，短头发！
MVC
I have an action protected by an [Authorize(Roles = "Admin")] Disabling this attribute does appear to solve my problem and then later on, not. So, sorry if any earlier statements confused. lol, short on hair!
[GET("Test")]
public ActionResult Test()
{
Console.WriteLine("Test");
return new EmptyResult();
}
任何JavaScript脚本文件不被保护的窗体身份验证的文件夹后面。
Any javascript script files are not behind a folder that is protected with forms authentication.
jQuery的doc.ready
我有我已经习惯了暂停调试，看看对象的内容的jQuery的错误事件。
I have a jQuery error event which I have used to pause debugging on to see the contents of the objects.
//-- while I am using this method, I have also used the `error: `
//-- part of $.ajax with the same result.
$(function ()
{
$(document).ajaxError(function (event, jqxhr, settings, exception)
{
Debug.Log("event: " + event);
Debug.Log("jqxhr: " + jqxhr.responseText);
Debug.Log("settings: " + settings);
Debug.Log("exception: " + exception);
});
});
我有一个jQuery的方法，它加载采用下列事件。虽然followig脚本看起来像它会踩住服务器。还有就是定时逻辑来确保只命中每5秒。
I have a jQuery method which loads using the following events. While the followig script looks like it would slam the server. There is timing logic to ensure it only hits every 5 seconds.
$(document).on('mousemove','*',function(e){ TestMethod(this,e,'mousemove');});
Javascript方法
这是我的ajax调用它很简单，只要我能做到这一点。
This is my ajax call which is as simple as I can make it.
function TestMethod(sender, e, eventTrgger)
{
$.ajax(
{
type: "GET",
url: '/Test',
dataType: 'html',
success: function (html)
{
//-- tested with nothing here.
}
});
}
提琴手
当错误发生时，提琴手不显示GET请求，这意味着服务器没有打。另外，我把在行动断点调试确认操作不被打到。
When the error occurs, Fiddler does not show a GET request, meaning the server is not hit. Also, I place a debugger breakpoint in the action confirms the action does not get hit.
其他： 由于AJAX调用发生每隔5秒。虽然在页面上，看到的状态，0和无差错错误;我清空缓存并无需刷新页面，Chrome和Ajax请求开始工作。为了记录在案，我的镀铬缓存seetings被设置为尽可能少的缓存，因为我允许配置。
Additional: Since the ajax call occurs every 5 seconds. While on the page and seeing status-0 and error-"error"; I clear the cache and without refreshing the page, chrome and the ajax request starts working. For the record, my chrome cache seetings are set to as little cache as I am allowed to configure.
推荐答案
这个问题似乎是与Chrome浏览器28如何处理缓存GET请求的错误。版本27工作正常，因为这样做在版本28 POST请求。
The issue appears to be a bug with how Chrome 28 handles caching for GET requests. Version 27 works fine, as do POST requests in version 28.
您可以通过设置您的$就高速缓存属性设置为false（）调用解决该问题。
You can workaround the issue by setting the 'cache' property to false in your $.ajax() call.
