Nginx 配置支持WebSocket 连接

配置很简单，增加一个Mapping 捕获参数。增加四个Header. 👇

upstream node {
     hash $remote_addr consistent;
     server 127.0.0.1:8080;
 }
 
 + map $http_upgrade $connection_upgrade {
 +     default upgrade;
 +     '' close;
 + }
 
 server {
     location / {
       proxy_pass http://node;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header Host $host:$server_port;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 
 +     proxy_set_header Upgrade $http_upgrade;
 +     proxy_set_header Connection $connection_upgrade;
 +     proxy_read_timeout 3600s;
 +     proxy_http_version 1.1;
     }
 
     server_name haha;
 
     listen 443 ssl; # managed by Certbot
     ssl_certificate /etc/haha; # managed by Certbot
     ssl_certificate_key /etc/haha; # managed by Certbot
     include /etc/haha; # managed by Certbot
     ssl_dhparam /etc/haha; # managed by Certbot
 
 }
 
 server {
     if ($host = haha) {
         return 301 https://$host$request_uri;
     } # managed by Certbot
 
     server_name haha;
     listen 80;
