SignalR拒绝工作

Question

Global.asax中:

void Application_Start(object sender, EventArgs e) 
{
    RouteTable.Routes.MapConnection<myconnection>("echo", "echo/{*operation}");
}

myconnection.cs

    public class myconnection : PersistentConnection
    {
        protected override Task OnReceivedAsync(string clientId, string data)
        {
            // Broadcast data to all clients
            return Connection.Broadcast(data);
        }
    }

〜/页/ Messages.aspx

<script src="http://code.jquery.com/jquery-1.7.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery.signalR.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(function () {
        var connection = $.connection('echo');

        connection.received(function (data) {
            $('#messages').append('<li>' + data + '</li>');
        });

        connection.start();

        $("#broadcast").click(function () {
            connection.send($('#msg').val());
        });
    });
</script>

<input type="text" id="msg" />
<input type="button" id="broadcast" value="broadcast" />

<ul id="messages">
</ul>

错误:

SignalR:必须先启动连接,然后才能发送数据..send()之前调用.start()

到目前为止我尝试了什么:

<configuration>
   <system.webServer>
        <modules runAllManagedModulesForAllRequests="true">
        </modules>
    </system.webServer>
</configuration>

<script type="text/javascript" src='<%= ResolveClientUrl("~/signalr/hubs") %>'></script>

这两个解决方案(https://github.com/SignalR/SignalR/wiki/Faq)都没有解决我的问题.有任何想法吗)？谢谢.

确保正确配置echo脚本的URL :

var connection = $.connection('<%= ResolveClientUrl("~/echo") %>');

由于您~/Pages使用的文件夹echo不正确,因为您的路由需要/echo或者/appname/echo应用程序托管在虚拟目录中.
