NGINX - 如何为所有虚拟主机设置过期标头? [英] NGINX - How would I set expires headers for all virtual hosts?

问题描述

我正在寻找一种方法来设置服务器范围的过期标头，以便所有现有或新的虚拟主机都配置相同.不幸的是，我无法在每个虚拟主机的 conf 文件中执行此操作，因此我正在寻找一种方法来在服务器范围内设置以下指令.

I'm looking for a way to set server wide expires headers so that all existing or new virtual hosts will be configured the same. Unfortunately, I can not do this in each virtual host's conf file, so I am looking for a way to make the following directives server wide.

location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg
              |jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid
              |midi|wav|bmp|rtf)$ {
    expires max;
    log_not_found off;
    access_log off;
}

推荐答案

expires 指令可以放在 http 块中，因此被所有服务器块继承，并且他们的位置块.

The expires directive can be placed in the http block and is therefore inherited by all server blocks and their location blocks.

手册展示了一个使用 expires 指令和 map 变量的例子.请参阅本文档.

The manual shows an example of using the expires directive with a map variable. See this document.

您可以使用 $request_uri 而不是 $sent_http_content_type 来匹配您现有的正则表达式并实现与以下相同的行为:

You could use $request_uri rather than $sent_http_content_type to match your existing regex and achieve identical behaviour with:

map $request_uri $expires {
    default off;
    ~*.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)(?|$) max;
}    
expires $expires;

两个指令都放在 http 块内，但在任何 server 块外.

Both directives placed inside the http block but outside any server block.
