        $(function () {

          var connection = new signalR.HubConnectionBuilder().withUrl("http://localhost:52992/chatHub").build();
            // var connection = $.connection('http://localhost:8000/signalr');
            // connection
            connection.start().then(function () {

            }).catch(function (err) {
                return console.error(err.toString());
            });
            //接受消息
            connection.on("ReceiveMessage", function (message) {
                console.log(message);
                var obj = JSON.stringify(message);

                //var encodedMsg = msg;
                //var li = document.createElement("li");
                //li.textContent = encodedMsg;
                //document.getElementById("messagesList").appendChild(li);
            });
            $("#sendmessage").click(function() {
                //发送消息
                var msgObj = {
                    "Type": 1,
                    "LoginUserId": 3100003640,
                    "UserName": "孙凤才",

                connection.invoke("SendMessage", "sdad",JSON.stringify(msgObj)).catch(function (err) {
                    return console.error(err.toString());
