nginx-server_name-多个-，server_name-默认值

nginx server_name

nginx server_name 多个的话;空格隔开

server_name baidu.com baidu.me;

如果很多的话也可以用正则;我的需求;xxx-api-dev.zzg.me 统一跳转到127.0.0.1:8888

server {
        listen 80;
        server_name ~^.;-api-dev.zzg.me$;
 
        location / {
                proxy_set_header  Host  $host;
                proxy_set_header  X-Real-IP $remote_addr;
                proxy_pass http://127.0.0.1:8888;
}

nginx server_name 默认值

加一条默认的阻挡。

当所有server的规则都不匹配时;nginx会采用第一条server配置;所以一般第一条server会使用阻止页面。

server {
   listen 80 default_server;
   server_name _;

   return 404;
}

另外可以直接拦截OPTIONS请求;返回204;减轻真实服务器的性能消耗

    location / {
        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;;

        if ($request_method = ;OPTIONS;) {
            return 204;
        }
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header X_Real_IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
    }

或者

if ($request_method = ;OPTIONS;) {
      add_header ;Access-Control-Allow-Origin; ;$http_origin; always;
      add_header ;Access-Control-Allow-Methods; ;GET, POST, PUT, DELETE, OPTIONS; always;
      add_header ;Access-Control-Allow-Headers; ;Accept, Authorization, Cache-Control, Content-Type, DNT, If-Modified-Since, Keep-Alive, Origin, User-Agent, X-Requested-With, Token, x-access-token; always;
      # Tell client that this pre-flight info is valid for 20 days
      add_header ;Access-Control-Max-Age; 1728000;
      add_header ;Content-Type; ;text/plain charset=utf-8;;
      add_header ;Content-Length; 0;
      return 204;
    }
