nginx - cURL 檢索 PHP 文件，但通過 Web 瀏覽器訪問會提供原始碼

我在使用 nginx 時遇到了一些問題。我在 Raspberry Pi B+ (Raspbian Jessie) 和 PHP 上使用 FastCGI 設置了 nginx。當我嘗試使用 cURL 檢索頁面時，它返回 PHP 生成的 HTML。

為 fastcgi 請求提供服務的 nginx 伺服器塊

server {
   listen 80 default_server;
   listen [::]:80 ipv6only=on default_server;

   # SSL configuration
   #
   # listen 443 ssl default_server;
   # listen [::]:443 ssl default_server;
   #
   # Self signed certs generated by the ssl-cert package
   # Don't use them in a production server!
   #
   # include snippets/snakeoil.conf;

   root /usr/share/nginx/html;

   # Add index.php to the list if you are using PHP
   index index.php index.html index.htm index.nginx-debian.html;

   server_name _;

   location / {
           # First attempt to serve request as file, then
           # as directory, then fall back to displaying a 404.
           try_files $uri $uri/ =404;
   }

   # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
   #
   location ~ \.php$ {
   #       include snippets/fastcgi-php.conf;
           include fastcgi_params;
           try_files $uri =404;
           fastcgi_split_path_info ^(.+\.php)(/.+)$;

   #
   #       # With php5-cgi alone:
   #       fastcgi_pass 127.0.0.1:9000;
           # With php5-fpm:
           fastcgi_pass unix:/var/run/php5-fpm.sock;
           fastcgi_index index.php;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

   }


   # deny access to .htaccess files, if Apache's document root
   #oncurs with nginx's one
   #
   #location ~ /\.ht {
   #       deny all;
   #}
}

PHP文件

<?php
echo "PHP Test";
?>

瀏覽器響應：下載它（chrome）或將其顯示為原始碼（其他瀏覽器）

捲曲：

• 在 DNS 記憶體中找不到主機名
• 正在嘗試 ::1…
• 連接到 localhost (::1) 埠 80 (#0)

GET /test_2.php HTTP/1.1 使用者代理：curl/7.38.0 主機：localhost 接受：/

< HTTP/1.1 200 正常

• 伺服器 nginx 未列入黑名單 < 伺服器：nginx < 日期：Fri, 12 May 2017 04:21:20 GMT < Content-Type: text/html; charset=UTF-8 < Transfer-Encoding: chunked < Connection: keep-alive < PHP Test
• 到主機 localhost 的連接 #0 保持不變

nginx access.log

編輯：在蒂姆下面的評論之後，我執行 curl 強制 IPv4，它確實返回了原始碼。

我想我知道為什麼會這樣。我使用 RegEx 解析所有名稱的第二個伺服器塊~.設置為偵聽 IPv4 埠 80，並且它沒有 CGI 處理程序。但是，預設伺服器塊設置為在埠 80 上偵聽 IPv6。由於 nginx 僅在測試其他伺服器後才回退到預設伺服器，因此代理伺服器塊無法處理 PHP，因此它將其作為原始碼返回。在 IPv6 上，nginx 無法使用代理伺服器塊來處理請求，因此它將它傳遞給執行 FastCGI 伺服器的預設伺服器，因此它可以返回phpinfo().

解決方案

我應該將 location /git/代理通行證塊放在預設伺服器塊中。
