AS3重置UrlLoader缓存 [英] AS3 Resetting UrlLoader Cache

问题描述

美好的一天，

我在Actionscript 3中遇到了UrlLoader缓存的问题. 我向php网站发出UrlRequest以获得时间戳.

I’ve encountered problems with the cache of the UrlLoader in Actionscript 3. I make a UrlRequest to a php site to get a timestamp.

当我第二次调用初始化类(包含函数)时，结果是相同的. 我必须关闭该应用程序并重新启动它才能获得新的请求.

When I call initiate the class (which contains the function) a second time, the result is the same. I have to close the application and restart it to get a new request.

我尝试过"loader = new loader".并使用标题.

I have tried "loader = new loader." and also using headers.

为每个请求创建唯一URL的选项 like here ，对我不起作用，因为它会破坏我的php操作..

The option of creating a unique URL for every request like here , does not work for me since it would sabotage my php action..

   loader = new URLLoader();
   var request:URLRequest = new URLRequest("http://www.mySite.com/getTime.php?action=getTime");
   loader.load(request);

推荐答案

向请求中添加随机参数不会以任何方式破坏您的php:

Adding a random parameter to your request will not sabotage your php in any way:

loader = new URLLoader();
var request:URLRequest = 
    new URLRequest(
   "http://www.mySite.com/getTime.php?action=getTime&bogus="+(Math.random() * 10000));
loader.load(request);

您的php代码将获取action参数，并且将忽略bogus参数，而对您的代码没有任何影响.

Your php code will GET the action parameter, and will ignore the bogus parameter without any effect on your code.

您还可以使用基于时间的随机数来避免太不幸，并且两次获得相同的值.

You can also use a time based random number to avoid being too unlucky and get the same value twice.
