nginx rewrite重写规则与防盗链配置方法

nginx rewite 规则,官方文档:http://wiki.nginx.org/NginxHttpRewriteModule

nginx rewrite规则格式:rewrite regex replacement flag 

flag标记有四种格式:
 

last – 相当于Apache中的L
break – 中止Rewirte,不在继续匹配
redirect – 返回临时重定向的HTTP状态302,相当于Apache中的R
permanent – 返回永久重定向的HTTP状态301,相当于Apache中的R=301
 

可以放在server, location 和 if 模块中。

匹配判断:
~  为区分大小写匹配; !~为区分大小写不匹配
~* 为不区分大小写匹配;!~为不区分大小写不匹配

例如,设定nginx在用户使用ie的使用重定向到/nginx-ie目录下:
 

if ($http_user_agent ~ MSIE) {
  rewrite  ^(.*)$  /msie/$1  break;
}

附,常用nginx Rewrite 规则配置代码。

1、只使用一个网址,比如主力网址设为www.xfcodes.com。
 

if ($host != 'www.xfcodes.com' ) {
rewrite ^/(.*)$ http://www.xfcodes.com/$1 permanent;
}
 

访问xfcodes.com时,会自动跳转到www.xfcodes.com。

2、防盗链
 

location ~* .(gif|jpg|png|swf|flv)$ {
valid_referers none blocked xfcodes.com dgjs123.com;
if ($invalid_referer) {
return 403;
}
}
 

盗链时则返回403错误,允许的域名可以直接跟在第二行的域名后面。

3、WordPress的Rewrite
 

location / {
index index.html index.php;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}
 

目前,代码收藏上就是使用的这段代码。
