nginx的SCRIPT_NAME, PATH_INFO多了index.php问题

在使用nginx进行 反向代理配置时通过正则表达式配置location后发现

通过$_SERVER['SCRIPT_NAME']; 与$_SERVER['PATH_INFO'] 发现直接获取了整个uri地址

访问uri： 127.0.0.1/index.php/site/login

正常情况应该为index.php

先获取为index.php/site/login

以下是解决方法

server {  
listen 80;  
server_name test.com;  
  
access_log  /home/swin/oaih/dev/logs/access.log;  
error_log /home/swin/oaih/dev/logs/error.log;  
  
root /home/swin/oaih/dev/public;  
index index.php index.html index.htm;  
  
location / {  
if (!-e $request_filename) {  
rewrite ^/(.*)$ /index.php/$1 last;  
}  
}  
  
location ~ .php$ {  
fastcgi_pass 127.0.0.1:9000;  
fastcgi_index index.php;  
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
  
include /etc/nginx/fastcgi_params;  
}  
  
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;  
fastcgi_index index.php;  
fastcgi_param SCRIPT_FILENAME $document_root$script;  
fastcgi_param SCRIPT_NAME $script;  
fastcgi_param PATH_INFO $path_info;  
  
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 REQUEST_URI $request_uri;  
fastcgi_param DOCUMENT_URI $document_uri;  
fastcgi_param DOCUMENT_ROOT $document_root;  
fastcgi_param SERVER_PROTOCOL $server_protocol;  
  
fastcgi_param GATEWAY_INTERFACE CGI/1.1;  
fastcgi_param SERVER_SOFTWARE nginx;  
  
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;  
fastcgi_param REDIRECT_STATUS 200;  
  
}  
  
}  

第一个位置指令设立的基本选项，而第二个location指令匹配一个请求到自身的index.php，并把它传递到FastCGI来处理。下一次请求index.php是没有进行正确的配置。

在处理我们的问题的整个配置文件的关键部分是这样的：

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;  
fastcgi_index index.php;  
fastcgi_param SCRIPT_FILENAME $document_root$script;  
fastcgi_param SCRIPT_NAME $script;  
fastcgi_param PATH_INFO $path_info;  
}  

location指定匹配所有的php请求将不指定为先前的全部uri， 它还清空$path-info变量,  if语句匹配任何类似下面的请求：http://mysite/index.php/foo和放入的index.php的$script变量和/ foo $path_info变量。

$script and $path_info将被插入到服务器变量SCRIPT_NAME和PATH_INFO的fastcgi的参数，并允许PHP妥善处理请求。
