使用不带$ args的原始$ request_uri设置fastcgi_cache_key [英] Set fastcgi_cache_key using original $request_uri without $args

问题描述

我正在尝试集成WordPress插件(Jetpack的Related Posts模块)，该插件将查询字符串添加到帖子URL的末尾.我想用FastCGI缓存URL，而完全忽略查询字符串/$args.

I am trying to integrate a WordPress plugin (Jetpack's Related Posts module) which adds query strings to the end of post URLs. I would like to cache URLs with FastCGI while completely ignoring the query strings/$args.

我当前的配置是:fastcgi_cache_key "$scheme$request_method$host$request_uri";

我知道使用此处提到的解决方案，对于包含特定$arg的URL，我的$skip_cache变量将关闭，这是可行的.但是，无论$args的值如何，我都希望缓存相同的结果，而不是为每组$args使用唯一的缓存键.

I am aware of using the solution mentioned here to turn my $skip_cache variable off for URLs containing a certain $arg, which works. However, I want to cache the same result regardless of the value of the $args rather than using a unique cache key for each set of $args.

我也知道一些建议，只需在fastcgi_cache_key而不是$request_uri;但是，由于$uri不仅是原始请求的URI减去$args，因此WordPress体系结构中的某些内容(可能是漂亮的链接)会强制所有请求的URI返回相同的缓存结果(而不是每个页面都返回不同的结果).

I am also aware of some suggestions to just use $uri in the fastcgi_cache_key rather than $request_uri; however, because $uri is not just the original requested URI minus the $args, something in the WordPress architecture (likely pretty links) forces all requested URIs to return the same cache result (rather than a different result for each page).

有什么方法可以真正使用最初请求的URI，而不必在缓存键中包含$args?

Is there any way to truly use the originally requested URI without including the $args in the cache key?

推荐答案

直到现在，我也遇到了类似的问题. 所以，我的解决方案:

Just now, I had similar problem. So, my solution:

在nginx配置中添加到

In the nginx config add to the

http  { 
    ...
    map $request_uri $request_path { 
       ~(?<captured_path>[^?]*) $captured_path; 
    }
    ...
}

然后，您将有一个变量$ request_path，其中包含$ request_uri，而没有query_string.

Then you will have a variable $request_path, which contains $request_uri without query_string.

因此使用$ request_path作为缓存键

So use $request_path for cache key

fastcgi_cache_key "$scheme$request_method$host$request_path"

重要. "map"伪指令只能添加到"http {}"中.该指令将对所有主机的所有请求执行.

Important. The "map" directive can be added only to "http {}". This directive will be execute for all requests for all hosts.
