php – Nginx快速CGI缓存ON error_page 404

Nginx 前端之家
前端之家收集整理的这篇文章主要介绍了php – Nginx快速CGI缓存ON error_page 404，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我想缓存(fast_cgi)404响应.

  1. error_page 404 = /url_rewriting.PHP;

在我的url_rewriting.PHP中,我使用PHP生成图像：

  1. if(strpos($_SERVER['REQUEST_URI'],'render/framed/file') !== FALSE) {
  2.     $urlBlocks = ['VR','sizePixels','image','ver','frame','borderSize','mat','matSize','maxSize','frameGlass','minSize'];
  3.     foreach($urlBlocks as $oneBlock) {
  4.         if($pos = array_search($oneBlock,$urlParts)) {
  5.             if(isset($urlParts[($pos+1)]) && $urlParts[($pos+1)] != '') {
  6.                 $_GET[$oneBlock] = urldecode($urlParts[($pos+1)]);
  7.             }
  8.         }    
  9.     }
  11.     chdir('include/PHP/render/framed');
  12.     header('Status: 200 OK',false,200);
  13.     require ('include/PHP/render/framed/render_img.PHP');
  14. }

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

哪个jpg文件不存在但由PHP生成.

但我没有找到任何方法与Nginx缓存这些PHP生成的图像.

我试过这个：

  1. set $no_cache 0;
  3. location ~ /render/ {
  4.         include snippets/fastcgi-PHP.conf;
  5.         #fastcgi_pass unix:/run/PHP/PHP7.0-fpm.sock;
  6.         fastcgi_pass 127.0.0.1:9000;
  8.         fastcgi_buffers 8 16k; # increase the buffer size for PHP-FTP
  9.         fastcgi_buffer_size 32k; # increase the buffer size for PHP-FTP
  10.         fastcgi_cache_key $scheme$host$request_uri$request_method;
  11.         fastcgi_cache PROD;
  12.         fastcgi_cache_valid any 20d;
  13.         fastcgi_cache_valid 404 20d;
  14.         fastcgi_cache_use_stale updating error timeout invalid_header http_500 http_503;
  15.         fastcgi_ignore_headers Cache-Control Expires Set-Cookie;
  16.         fastcgi_hide_header "Set-Cookie";
  17.         fastcgi_cache_bypass $no_cache;
  18.         fastcgi_no_cache $no_cache;
  19.         expires 10M;
  20.         access_log off;
  21.         add_header Cache-Control "public";
  22.         add_header X-Cache-Status $upstream_cache_status;
  23. }

它适用于图像URL

  1. https://mywebsite.com/include/PHP/render/framed/img.PHP?VR=1&size=300&image=U3pmwKi

但不适用于图片网址

  1. 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;？

这是2卷曲-I输出：

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：

  1. location ~ (render_img.PHP|^/url_rewriting.PHP$) {
  2.     fastcgi_cache...stuffs to cache...
  3. }

我们无法检查位置^〜/ render / framed / {因为它是对应于/url_rewriting.PHP的404响应.

最佳答案
您的问题是,在该位置调用.PHP时,您需要优先考虑.PHP块而不是/ render / framed /.它仍然被.PHP块捕获

因此,您需要在下面使用您的位置块.你需要使用

  1. location ^~ /render/framed/ {
  2.   ...
  3. }
