使用Nginx对Websocket进行*

一. Nginx配置示例

http {    
    map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }
    
    server {
        listen       6080;
        server_name  10.5.30.110;

        location ^~ /st-websocket {
            proxy_pass http://10.5.17.154:7072/real
            proxy_http_version 1.1;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_read_timeout 120s;

            proxy_set_header Upgrade websocket;
            proxy_set_header Connection Upgrade;
        }
    }
}

二. html使用实例

<html>
<body>
<script>
  var realSocketAddress = "ws://10.5.30.110:6080/st-websocket";
  var socketTimeStamp = 1576140668626;
  var socketAuth = "ce6dfe74b870555d9f2d278cd0a6380d";
  openRealWebSocket();
  function openRealWebSocket(){
    if (window.WebSocket) {
        realSocket = new WebSocket(realSocketAddress);
        realSocket.onmessage = function (event) {
        };
        realSocket.onopen = function (event) {
            //注册
            var data = {};
            data.type = "REGISTER";
            data.timeStamp = socketTimeStamp;
            data.auth = socketAuth;
            sendRealSocketMsg(JSON.stringify(data));
        };
        realSocket.onclose = function (event) {
            alert("实时数据websocket已关闭");
        };
    }
  }

  function sendRealSocketMsg(message) {
    if (!window.WebSocket) {
        return;
    }
    if(realSocket){
        if (realSocket.readyState == WebSocket.OPEN) {
            realSocket.send(message);
        } else {
            realSocket.close();
        }
    }
}
</script>
</body>
</html>
