注意點:
如果網站使用HTTPS,WebSocket必須要使用wss協議;
使用wss協議的連接請求必須只能寫域名,而非IP+端口;
建議在URL域名后面為websocket定義一個路徑,本例中是/socket/;
var socket = new WebSocket("wss://www.aabb.cn/socket/");
location /socket/ {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
}
注意:
1、location /socket/ {...}這里要格外注意!
html中的url是 wss://www.aabb.com/socket/,所以Nginx配置中一定要是 /socket/
如果前端是 wss://www.aabb.com/socket,Nginx對應是 /socket
2、proxy_pass對應的最好是公網IP加端口號, 'localhost','127.0.0.1'
3、proxy_http_version 1.1 版本號必須是1.1,這條配置必需
其他:
#服務器socket連接端口9999,為了避免沖突,這里用9990反向代理到9999,同時實現了wss轉ws,服務器端不需要做修改
server {
listen 9990;
server_name xx.xx.xx.xx;
ssl on;
ssl_certificate "/usr/cert/barrage.crt";
ssl_certificate_key "/usr/cert/barrage.key";
ssl_protocols SSLv3 SSLv2 TLSv1 TLSv1.1 TLSv1.2;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_prefer_server_ciphers on;
location /{
#反向代理到9999端口,同時協議轉換為http,這樣服務器端代碼就不需要做修改
proxy_pass http://120.77.222.242:9999;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
#由於服務器端源碼(建議大家做好大小寫匹配)只匹配了"Upgrade"字符串,所以如果這里填"upgrade"服務器端會將這條http請求當成普通的請求,導致websocket握手失敗
proxy_set_header Connection "Upgrade";
proxy_set_header Remote_addr $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_read_timeout 600s;
}
}
假設下面四種情況分別用 http://192.168.1.1/proxy/test.html 進行訪問。
第一種:
location /proxy/ {
proxy_pass http://127.0.0.1/;
}
代理到URL:http://127.0.0.1/test.html
第二種(相對於第一種,最后少一個 / )
location /proxy/ {
proxy_pass http://127.0.0.1;
}
代理到URL:http://127.0.0.1/proxy/test.html
第三種:
location /proxy/ {
proxy_pass http://127.0.0.1/aaa/;
}
代理到URL:http://127.0.0.1/aaa/test.html
第四種(相對於第三種,最后少一個 / )
location /proxy/ {
proxy_pass http://127.0.0.1/aaa;
}
代理到URL:http://127.0.0.1/aaatest.html
