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;
}
