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中使用图像src URL：
https://mywebsite.com/include/php/render/framed/file/VR/1/size/300/image/U3dpwK/the-cat.jpg
哪个jpg文件不存在但由PHP生成。
但我没有找到任何办法让Nginx缓存这些php生成的图片。
我试过了：
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;
}
它适用于图片网址
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
但我放了fastcgi_cache_valid 404 20d;
那么，如何缓存error_page 404 = /url_rewriting.php;上的脚本？

解
正如Tarun Lalwani所说，阻止优先顺序和顺序很重要。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location ^~ /render/framed/ {，因为它是与/url_rewriting.php对应的404响应。
答案 0 :(得分：4)
您的问题是，在该位置调用.php时，您需要优先考虑/render/framed/，而不是.php。它仍然被.php块
所以你需要在下面使用你的位置块。你需要使用
location ^~ /render/framed/ {
...
}
