``` 如使用wss则需配置Nginx转发 ``` location /wss { proxy_pass http://127.0.0.1:3006; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; rewrite /wss/(.*) /$1 break; proxy_redirect off; } ``` 测试 ``` redis_sub("demo",function($channel,$message){ echo "channel ".$channel."\n"; print_r($message); }); ``` ### pusher [](#pusher) ``` PUSHER_APP_KEY = PUSHER_APP_SECRET = PUSHER_APP_ID = PUSHER_APP_CLUSTER = ``` 前端需要加载JS ``` var pusher = new Pusher("", { cluster: "", }); var channel = pusher.subscribe("netteadmin"); channel.bind("notice", (data) => { console.log(data); }); ``` 发送消息 ``` helper_v3\Pusher::sender($channel,$event,$data = []); 或使用 send_pusher($data = [],$channel='netteadmin',$event='notice'); ``` ### xcookie 加密 [](#xcookie-加密) ``` //设置 xcookie("ss",1);
