nginx配置支持php的pathinfo模式配置方法

nginx模式不支持pathinfo模式，类似info.php/hello形式的url会被提示找不到页面。下面的通过正则找出实际文件路径和pathinfo部分的方法，让nginx支持pathinfo。

location ~ \.php$ {
root      html;
fastcgi_pass  127.0.0.1:9000;
fastcgi_index index.php;
 
##通过设置模拟出pathinfo
set $path_info “”;
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ “^(.+?\.php)(/.+)$”) {
 set $real_script_name $1;
 set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;
 
include    fastcgi_params;
}

要点：

1.~ \.php 后面不能有$  以便能匹配所有 *.php/* 形式的url
2. 通过设置更改 SCRIPT_FILENAME

我在实际使用张将这段代码融合到了fastcgi_params中。下面是我的nginx配置文件示例：
配置虚拟主机部分，支持pathinfo的nginx代码如下：

## 在nginx.conf的server部分：

server {
listen    8080;
server_name localhost;
 
location ~ \.php {
include    fastcgi.conf;
}
}

##要点： \.php 后面没有$，以便匹配所有 *.php/* 形式
##重点代码见 fastcgi.conf 开头部分

fastcgi.conf 代码如下：

fastcgi_pass  127.0.0.1:9000;
##fastcgi_index index.php;

set $path_info "";
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;
## 以上是支持pathinfo的重点部分

fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE  nginx;

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_FILENAME  $document_root$fastcgi_script_name;
#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 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;

自己的配置：

server
{
listen    80;
server_name www.touchopenid.com;
index index.html index.htm index.php;
root /data0/htdocs/openid;
 
location ~ \.php($|/) {
set $script   $uri;
set $path_info "";
if ($uri ~ "^(.+\.php)(/.+)") {
set $script   $1;
set $path_info $2;
}
fastcgi_pass  127.0.0.1:9000;
include    fastcgi_params;
fastcgi_param PATH_INFO        $path_info;
fastcgi_param SCRIPT_FILENAME     $document_root$script;
fastcgi_param SCRIPT_NAME       $script;
}
