Nginx-location的匹配规则（nginx配置文件中的location）

1）空格，默认匹配，普通匹配

 location / {
           root   D:\TRMS\project-jl\dist;
           index  index.html index.htm;
       }

2）精准匹配/home/zhoujin

 location =/zhoujin {
           root  /home;
           index  index.html index.htm;
       }

3)匹配正则表达式，不区分大小写：~*

 location ~ \.(gif|gpg|png|PNG){
           root   /home/zhoujin
       }

4)匹配正则表达式，区分大，小写：~

 location ~* \.(gif|gpg|png|PNG){
           root   /home/zhoujin
       }

5）以某个字符路径开头^

 location ^* \.(gif|gpg|png|PNG){
           root   /home/zhoujin
       }

Nginx跨域问题

www.baidu.com---->www.zhoujin.com请求数据

Cross_origin Resource sharing：跨域资源共享

解决方案：jsonp,Springboot Cors,Nginx

 add_header Access-Control-Allow-Origin *;
 add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
 add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';

Nginx静态资源防盗链:只允许zhoujin.com域名的访问

#对源站点进行验证
valid_referes *.zhoujin.com;
if($invalid_referer){
  	return 404;
}
