WebSocket connection to 'ws://localhost/aa/ws1' net::ERR_CONNECTION_REFUSED

在项目中使用了websocket 进行数据推送 在本地访问没问题 部署到服务器上之后报 WebSocket connection to 'ws://localhost/aa/ws1'  net::ERR_CONNECTION_REFUSED

很是郁闷!!

后面发现服务器上使用了nginx,发现也需要在nginx中配置websocket

前台

function init(){
    if ('WebSocket' in window) {
websocket = new WebSocket("ws://localhost/aa/ws1");
} else if ('MozWebSocket' in window) {
websocket = new MozWebSocket("ws://localhost/aa/ws1");
} else {
websocket = new SockJS("http://localhost/aa/ws1/sockjs");
}
websocket.onopen = function() {
        console.log('open');

};

后台

registry.addHandler(new MyHandler(), "/ws1");

registry.addHandler(new MyHandler(), "/ws1/sockjs").addInterceptors(new MyHandlShakeInterceptor()).withSockJS();

nginx配置

upstream test{
        server localhost:8080;   

}

location /aa/ws1 {

proxy_pass http://test;
proxy_redirect off;


proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;


proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";


}

解决~~
