nginx配置总结

1、跨域处理

location / {
    add_header Access-Control-Allow-Origin *;
    add_header Access-Control-Allow-Credentials true; ##可选
    add_header Access-Control-Request-Headers custom-Key;//添加自定义请求头   
    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;
    add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
    if ($request_method='OPTIONS'){
        return 204;
    }
} 

2、跳转到https

server{
   listen 80;
    server_name localhost;
    rewrite ^(.*) https://$host$1 permanent; ##跳转到https;
}

 3、禁用缓存

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css)$ {
 #禁止缓存，每次都从服务器请求
  add_header Cache-Control no-store;
}
