無法達到POST請求緩存的嵌套位置指令

Question

我正在配置NginX以支持緩存GET請求+特定的POST請求。 我正在使用symfony框架，因此將URI重寫爲：app.php/...。

爲了能夠分開處理GET和POST緩存，我創建了一些嵌套位置指令。

fastcgi_cache_path /nginx_cache_path levels=1:2 keys_zone=one:10m max_size=1g inactive=120m loader_threshold=300 loader_files=150; 

server { 
    listen 80; 
    server_name example.com www.example.com; 

    if ($request_method !~ ^(GET|HEAD|POST)$) { 
     return 444; 
    } 

    root /path_to_web_server; 

    location/{    

     # try to serve file directly. If not existing change to app.php 
     try_files $uri /app.php$is_args$args;   

    } 

    location ~ ^/images/.*\.(gif|jpg|png)$ { 

     root /path_to_images_folder; 
    } 

    location ~ ^/app\.php(/|$) { 

     location ~ /post_request_path { 

      fastcgi_cache_key "$request_uri|$request_body"; 
      fastcgi_cache_valid 5m;   
      fastcgi_cache_methods POST; 

      fastcgi_cache one; 
      fastcgi_cache_use_stale updating error timeout invalid_header http_500 http_503 http_404; 

      fastcgi_ignore_headers Cache-Control Expires Set-Cookie; 
      add_header X-Fastcgi-Cache $upstream_cache_status; 
      fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; 
      fastcgi_split_path_info ^(.+\.php)(/.*)$; 
      include fastcgi_params; 

      fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name; 
      fastcgi_param DOCUMENT_ROOT $realpath_root; 

      internal; 
     } 

     location ~/{ 

      fastcgi_cache_key $scheme$host$request_uri$request_method; 
      fastcgi_cache_valid 60m;   
      fastcgi_cache_methods GET HEAD; 

      fastcgi_cache one; 
      fastcgi_cache_use_stale updating error timeout invalid_header http_500 http_503 http_404; 

      fastcgi_ignore_headers Cache-Control Expires Set-Cookie; 
      add_header X-Fastcgi-Cache $upstream_cache_status; 
      fastcgi_pass unix:/var/run/php/php7.0-fpm.sock; 
      fastcgi_split_path_info ^(.+\.php)(/.*)$; 
      include fastcgi_params; 

      fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name; 
      fastcgi_param DOCUMENT_ROOT $realpath_root; 

      internal; 
     } 
} 

我的問題：POST請求從不緩存。 「location〜/ post_request_path」已經過測試，但從未被NginX選中。

按照nginx的調試日誌文件：

2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: "/" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "^/images/.*\.(gif|jpg|png)$" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "^/app\.php(/|$)" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "\.php$" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 using configuration "/" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 internal redirect: "/app.php?" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: "/" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "^/images/.*\.(gif|jpg|png)$" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "^/app\.php(/|$)" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "/post_request_path" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 test location: ~ "/" 
2017/07/11 19:31:00 [debug] 13707#0: *8961 using configuration "/" 

我很驚訝/ post_request_path因爲我以爲Nginx的算法選擇當數那些被匹配的URI的第一個匹配的正則表達式永遠不會選擇。

我想我失去了一些東西大着這裏嵌套的位置指示......

任何線索？

Answer 1

我自己找到了解決方案。我正在向錯誤的方向挖掘。問題不是來自嵌套位置指令，而是來自try_files之一。

的原因是我的眼睛下的調試日誌： 「/app.php」

2017/07/11 19:31:00 [debug] 13707#0: *8961 internal redirect: "/app.php?" 

Nginx的是rewritting的URI而不是「/app.php/post_request_path」

因此「錯誤的」位置指令路由​​。

修正

變化：

try_files $ URI /app.php$is_args$args;

到

try_files $ URI /app.php$uri;
