nginx开启pathinfo模式,运行后index.php的index会被过滤

服务器使用一键lnmp安装的，开启了pathinfo模式后发现使用header跳转时index会被过滤。

使用的是ThinkPHP系统，U方法与header location之后会出现这种情况，如：

http://xx.com/index.php/a/b

会变成

http://xx.com/.php/a/b

而地址栏输入没有问题

贴上配置文件

1、站点conf

server
    {
        listen 80;
        #listen [::]:80;
        server_name xx.com ;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /data;

        include none.conf;
        #error_page   404   /404.html;

        # Deny access to PHP files in specific directory
        #location ~ /(wp-content|uploads|wp-includes|images)/.*\.php$ { deny all; }

        #include enable-php.conf;

        include  enable-php-pathinfo.conf;

        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }

        location ~ .*\.(js|css)?$
        {
            expires      12h;
        }

        location ~ /.well-known {
            allow all;
        }

        location ~ /\.
        {
            deny all;
        }

        access_log  xx.com.log;
    }

2、enable-php-pathinfo.conf

location ~ [^/]\.php(/|$)
        {
            fastcgi_pass  unix:/tmp/php-cgi.sock;
            fastcgi_index index.php;
            include fastcgi.conf;
            include pathinfo.conf;
        }

3、fastcig.conf

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
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  REQUEST_SCHEME     $scheme;
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;
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";

4、pathinfo.conf

fastcgi_split_path_info ^(.+?\.php)(/.*)$;
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO       $path_info;
try_files $fastcgi_script_name =404;

解决办法

是由于 ThinkPHP.php 这个核心文件中的代码处理路由的问题， 代码如下：

define('IS_CGI',(0 === strpos(PHP_SAPI,'cgi') || false !== strpos(PHP_SAPI,'fcgi')) ? 1 : 0 );

我们把上述代码改为:

define('IS_CGI',substr(PHP_SAPI, 0,3)=='cgi' ? 1 : 0 );

修改完毕后代码就可以正常解析了；
