SignalR：＆QUOT;用户身份不能主动SignalR连接＆QUOT期间更改;误差Windows验证网站 [英] SignalR: "The user identity cannot change during an active SignalR connection" error with windows auth website

问题描述

我有一个MVC 5网站使用Windows身份验证运行signalR 2.1.0。因为我使用Windows身份验证登录/注销由IIS自动处理。偶尔我得到一个403错误说无法识别用户身份，用户身份不能主动SignalR连接过程中发生改变。这不会发生的时候，我似乎无法找到当它不工作到一个模式。有没有其他人遇到这个？

I have an MVC 5 website running signalR 2.1.0 using Windows Authentication. Because I'm using windows auth login/logout is handled automatically by IIS. Occassionally I'm getting a 403 error saying "Unrecognized user identity. The user identity cannot change during an active SignalR connection." This doesn't happen all the time, and I can't seem to find a pattern to when it does and does not work. Has anyone else encountered this?

下面是视图上的code：

Here is the code on the view:

<script type="text/javascript">
        $(document).ready(function() {
            SignalRSetup();
        });

        function SignalRSetup() {
            // Declare a proxy to reference the hub.
            var hub = $.connection.tokenRequestHub;

            // Create a function that the hub can call to broadcast messages.
            hub.client.updateFromService = function(tokenRequestID, message, success) {
                var msg = "Token Request ID {0} => {1}".format(tokenRequestID, message);
                var notyType = (success) ? 'success' : 'error';
                noty({ text: msg, type: notyType, timeout: 2000 });
                if (success) {
                    refreshGrids();
                }
            };

            $.connection.hub.start();//this is where it errors!
        }
</script>

任何帮助将大大AP preciated。

Any help would be greatly appreciated.

推荐答案

什么工作对我来说是在IIS设置来禁用匿名身份验证。

What worked for me was to disable Anonymous Authentication in the IIS settings.
