NginX 导致 PHP 文件执行两次

NginX 导致 PHP 文件执行两次

我进退两难,无法弄清楚为什么会发生这种情况。由于某种原因,当我打开我的网站时,index.php 文件正在被执行。我已经能够将其缩小到 NginX/PHP-FPM,方法是将其添加file_put_contents('runs.txt', 'executed'.PHP_EOL, FILE_APPEND);到 index.php 的顶部并使用网站和命令行执行它。如果我从命令行执行它,它只会输出一个executed,而如果我从网站(通过 NginX)执行它,它会输出两个executed。该脚本也不会重定向到自身,因为它只是返回一个 200 响应代码。除了通过两次执行脚本而必须使用更多内存之外,它还会通过第二次生成 CSRF 来破坏 CSRF 保护,因此 CSRF 毫无用处。

以下是我的 nginx 配置文件:

nginx.conf

user  nginx;
worker_processes  2;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    # Upstream to abstract backend connection(s) for PHP.
    upstream php {
        #this should match value of "listen" directive in php-fpm pool
        server unix:/var/lib/php-fpm.sock;
    }

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

php.conf

# Pass all .php files onto a php-fpm/php-fcgi server.
location ~ \.php$ {
        #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

        include fastcgi_params;

        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_read_timeout 600s;
#       fastcgi_intercept_errors on;
        fastcgi_pass php;
}

网站配置文件

server {
    listen       80;
    server_name  xyz.com www.xyz.com;
    root         /usr/share/nginx/xyz.com;
    #access_log  /usr/share/nginx/logs/xyz.com-access_log;
    error_log    /usr/share/nginx/logs/xyz.com-error_log;

    index index.php;

    location / {
       index index.php;

       try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    include php.conf;
}

fastcgi_params

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

如果我更改try_files $uri $uri/ /index.php?q=$uri&$args;try_files $uri $uri/;并启动,http://www.xyz.com/index.php那么它只会执行一次,但我需要/index.php?q=$uri&$args在那里。我正在运行带有 nginx 1.4.4 和 PHP 5.4.23 的 CentOS 6.5。有什么想法吗?

我找到了问题所在。由于如果指定的 URI 不存在,try_files就会自动重定向到index.php,因此缺少一张图片,当它打开时,它会index.php再次打开。

我能够确定丢失的图像,http://example.com/images/google.png因此我找到该图像并将其放在正确的文件夹中(而不是重定向回index.php)。

另一个更合适的解决方案是在文件中(块之前)有一个带有语句location /images的块,如果图像不存在,则发送 404 未找到状态代码。try_fileswebsite.conflocation /

location /images {
    try_files $uri =404;
}
