使用 php 新鲜加载页面而不是从缓存中加载

我刚刚将网站的开发版本移植到生产环境中，但它仍然显示旧图像并使用古老的样式表。这发生在每个人身上。

我

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma-directive" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Directive" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">

也尝试过，因为这是 WordPress，我只是将 css 排入队列，在末尾添加主题版本。所以 style.css?ver=2.0。

出于公司的需要，我在 IIS 上运行它。

这些选项似乎都不能正常工作。当用户访问该网站时，如何才能重新加载页面而不是从缓存中加载？

I just ported a development version of my site over to production and it's still showing old images and using ancient stylesheets. This is happening to everyone.

I tried

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma-directive" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Directive" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">

Also, because this is WordPress I just enqueue the css which adds the theme version at the end. so style.css?ver=2.0.

I'm running this on IIS out of corporate necessity.

None of these options seem to work properly. How can I load the page freshly and not from cache when users visit the site?

假设你在一个 PHP 页面中，只需在请求中附加一个随机数

<link rel="stylesheet" type="text/css" href="style.css?random=<?php echo rand(1,100000); ?>" />

你也可以在 CSS/JS/etc 文件中使用 PHP 标头来实现，但是你需要将 CSS 和 JS 解析为 PHP，这会有点麻烦凌乱的。

另一种选择是通过 htaccess 进行设置 - 由 http://www.askapache 提供.com/htaccess/using-http-headers-with-htaccess.html

<FilesMatch "\.(html|htm|js|css)$">
    FileETag None
    <IfModule mod_headers.c>
        Header unset ETag
        Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
        Header set Pragma "no-cache"
        Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
    </IfModule>
</FilesMatch>

Assuming you're in a PHP page, just append a random number to the request

<link rel="stylesheet" type="text/css" href="style.css?random=<?php echo rand(1,100000); ?>" />

You can also do it with PHP headers inside the CSS/JS/etc files, but then you need to parse CSS and JS as PHP and it gets a bit messy.

The other option is to set it up via htaccess - courtesy of http://www.askapache.com/htaccess/using-http-headers-with-htaccess.html

<FilesMatch "\.(html|htm|js|css)$">
    FileETag None
    <IfModule mod_headers.c>
        Header unset ETag
        Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
        Header set Pragma "no-cache"
        Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
    </IfModule>
</FilesMatch>
