我想缓存(fast_cgi)404响应.
error_page 404 = /url_rewriting.PHP;
在我的url_rewriting.PHP中,我使用PHP生成图像：
if(strpos($_SERVER['REQUEST_URI'],'render/framed/file') !== FALSE) {
$urlBlocks = ['VR','sizePixels','image','ver','frame','borderSize','mat','matSize','maxSize','frameGlass','minSize'];
foreach($urlBlocks as $oneBlock) {
if($pos = array_search($oneBlock,$urlParts)) {
if(isset($urlParts[($pos+1)]) && $urlParts[($pos+1)] != '') {
$_GET[$oneBlock] = urldecode($urlParts[($pos+1)]);
}
}
}
chdir('include/PHP/render/framed');
header('Status: 200 OK',false,200);
require ('include/PHP/render/framed/render_img.PHP');
}
通过这种方式,我可以在HTML中拥有图像src URL,如下所示：
https://mywebsite.com/include/PHP/render/framed/file/VR/1/size/300/image/U3dpwK/the-cat.jpg
我试过这个：
set $no_cache 0;
location ~ /render/ {
include snippets/fastcgi-PHP.conf;
#fastcgi_pass unix:/run/PHP/PHP7.0-fpm.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_buffers 8 16k; # increase the buffer size for PHP-FTP
fastcgi_buffer_size 32k; # increase the buffer size for PHP-FTP
fastcgi_cache_key $scheme$host$request_uri$request_method;
fastcgi_cache PROD;
fastcgi_cache_valid any 20d;
fastcgi_cache_valid 404 20d;
fastcgi_cache_use_stale updating error timeout invalid_header http_500 http_503;
fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
fastcgi_hide_header "Set-Cookie";
fastcgi_cache_bypass $no_cache;
fastcgi_no_cache $no_cache;
expires 10M;
access_log off;
add_header Cache-Control "public";
add_header X-Cache-Status $upstream_cache_status;
}
它适用于图像URL
https://mywebsite.com/include/PHP/render/framed/img.PHP?VR=1&size=300&image=U3pmwKi
但不适用于图片网址
https://mywebsite.com/include/PHP/render/framed/file/VR/1/size/300/image/U3dpwK/the-cat.jpg
然而我把fastcgi_cache_valid 404 20d;
那么,如何缓存mys_page上的脚本404 = /url_rewriting.PHP;？

解
正如Tarun Lalwani所说,块优先级和顺序很重要.但是,当你想缓存404响应时,你必须在error_page的文件名上检查它：
location ~ (render_img.PHP|^/url_rewriting.PHP$) { fastcgi_cache...stuffs to cache... }
我们无法检查位置^〜/ render / framed / {因为它是对应于/url_rewriting.PHP的404响应.
