jQuery的AJAX缓存动作禁止不工作？ [英] jQuery ajax cache disabling not working?

问题描述

我正在开发一个使用AJAX请求来检索信息的Firefox扩展。这是code：

I'm developing a Firefox extension that uses an ajax-request to retrieve information. This is the code:

$.ajax({
        url: "http://127.0.0.1/foo/bar/Service?wsdl" + new Date().getTime(),
        beforeSend: function(request) { request.setRequestHeader("SOAPAction", "Group"); },         
        async: false,
        cache: false,
        type: "POST",   
        dataType: "xml",
        data: req,
        contentType: "text/xml; charset=\"utf-8\"",
        success: function (data, textStatus, xmlHttpRequest) {
        out = $(xmlHttpRequest.responseXML);
        }
    }); 

我仍然得到同样的结果，当被发送到服务器的数据被改变。我试图避免通过添加到URL和缓存：假，新的日期（）的getTime（）。这似乎并没有工作。重新启动浏览器后，我得到正确的结果。

I still get the same result, when the data that is sent to the server is changed. I tried to avoid that by adding "new Date().getTime()" to the URL and "cache: false". This doesn't seem to work. After restarting the browser, I get the correct results.

有没有人有一个想法是什么问题？ 是否有某种形式的会话处理，因此服务器还是还给旧响应？

Does anyone have an idea what the problem is? Is there some kind of session-handling, so the server still gives back the old response?

编辑：我做了很多的测试和调试的，我想我发现了问题：有那么每一次我再来一次的要求保存每个AJAX请求包含会话ID的Cookie，服务器发送与会话ID cookie中的会话数据。非常糟糕的行为，我不知道饼干可以通过一个Ajax请求创建。 所以，我的一切都做的来解决这个问题是一个功能，我的每一个参数变化时，删除这个cookie。感谢您的再次帮助。

I did a lot of testing and debugging and I think I found the problem: there is a cookie saved with every ajax-request that contains a session-id, so every time I do the request again, the server sends data of the session with the session-id in the cookie. Really bad behavior, I didn't know that cookies could be created through an ajax-request. So everything I have to do to fix the problem is a function that deletes this cookie every time my parameters are changed. Thanks for your help again.

推荐答案

您可以试试这个

$(document).ready(function() {
  $.ajaxSetup({ cache: false });
});

试toger用的Math.random（）是在安全侧

try toger with Math.random() to be on safer side

日期（）的getTime（）一起的Math.random（）

Date().getTime() together with Math.random()

http://127.0.0.1/foo/bar/Service?wsdl" + new Date().getTime() + Math.random()
