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.

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

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：

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;？

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：

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.@H_403_94@

最佳答案@H_403_94@
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

location ^~ /render/framed/ {
  ...
}
