'websocket: connection error'

Question

'websocket: connection error', 'The operation couldn’t be completed. Connection refused'

开发环境如下：
react-native-cli: 2.0.1
react-native: 0.55.1
求拯救？

Answer 1

    var m={};//发送给后台验证消息
    var ws = new WebSocket(wsObj.url);
    ws.onopen = function () { //开始连接
        ws.send(JSON.stringify(m));
        wsObj.resetHeart();
        if (w1) {
            userList = [];
        }
        console.log("建立连接：", wsObj.name);
    };

你连接失败，看和后台有没有配对成功
