使用AJAX在php和html上禁用缓存 [英] Disable cache on php and html with AJAX

问题描述

我的网站使用AJAX，而我的网站在AJAX准备好文档后部分加载，并且这些部分是动态的。

示例一部分：Hello＃USERNAME＃这对于每个ID都是不同的，当我登录到第一个ID时显示我的用户名，但是当登录到第二个ID时，这个名称不会改变，并显示第一个ID用户名。

 <？php 
 header（Cache-Control： no-store，no-cache，must-revalidate，max-age = 0）; 
头（Cache-Control：post-check = 0，pre-check = 0，false）; 
标题（Pragma：no-cache）; 
？> 
  

但缓存不会被禁用。 >解决方案

我相信这个问题有点重复。但是，如果您希望确保缓存不会发生在ajax调用上，则可以将时间戳添加到您要访问的URL的末尾。

JavaScript中的示例AJAX的准备：

  var time_stamp = new Date（）。getTime（）; 
 var myurl =url_here.php？timestamp =+ time_stamp; 
 jQuery.get（myurl，/ *更多参数* /）; 
 / *其他相关代码* /

• 停止jQuery .load被缓存的响应

另一件事是考虑它可能不是缓存问题。您是否正确清除任何会话/ cookies？ （如果你正在使用它们）

I use AJAX for my website and my website some part load after document is ready by AJAX and those parts are dynamic.

Example one part: Hello #USERNAME# this is different for every ID, When i log in to first ID show my username but when log in to second ID this name do not change and show first ID username.

I disabled cache in all PHP pages by above code:

<?php 
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

But cache is not disabled.

解决方案

I believe this question is a little bit of a duplicate. However, if you want to ensure that caching does not happen on ajax calls, you can append a timestamp to the end of the URL you are hitting.

Example in your JavaScript AJAX prep:

var time_stamp = new Date().getTime();
var myurl = "url_here.php?timestamp=" + time_stamp;
jQuery.get(myurl, /* more parameters */);
/* other relevant code */

Another thing to consider is that it might not be a caching issue. Are you properly clearing any sessions/cookies? (If you are using them)
