SignalR协商404 [英] SignalR Negotiate 404

问题描述

我正在使用SignalR 2.0.在VS 2012上本地运行时，一切正常.但是，当我在IIS上发布站点时，它会中断.该站点已加载，但其中一个脚本返回404 Not Found.该脚本类似于.

I am using SignalR 2.0. Everything works fine when running locally on my VS 2012. But when I publish the site on IIS, it breaks. The site loads but one of the scripts returns 404 Not Found. The script is something like.

https://example.com/signalr/negotiate?xxx

此路径确实不存在.正确的路径应为:

This path doesn't exist indeed. The correct path should be:

https://example.com /private /signalr/negotiate?xxx

https://example.com/private/signalr/negotiate?xxx

请注意以粗体显示的部分.

Note the part in bold.

在网站内( https://example.com/)我有另一个应用程序(

Inside the WebSite (https://example.com/) I have another Application (https://example.com/private/). This one is using SignalR.

这似乎是SignalR中的错误，因为可以从我的私人站点访问信号器/集线器路径.

This seems like a bug in SignalR since the signalr/hubs path is accessible from my private site.

推荐答案

我遇到了类似的问题. 这是用于配置的文档/signalr URL .

I had a similar problem. Here is the documentation for configuring the /signalr URL.

但是，我的解决方案与文档不同. 我没有更改标准的app.MapSignalR()，而是将客户端代码更改为使用/MyApp/signalr.这是代码，其中"MyApp"是我的Web应用程序的虚拟目录.

However, my solution differed from the docs. Instead of changing the standard app.MapSignalR(), I changed my client code to use /MyApp/signalr. Here is the code where "MyApp" is the virtual directory of my web application.

        var connection = $.hubConnection('/MyApp/signalr', {useDefaultPath: false});
        var changesHub = connection.createHubProxy('changesHub');

        changesHub.on('userCountChanged', function (count) {
            $('#user-count').text(count);
        });

        connection.start().done(function () {
            console.log('Hub has started');
            changesHub.invoke('subscribeToChanges', user.id);
        });

我尝试了另一种方法(将MapSignalR更改为/signalr路径)，但这没有用，并且协商仍路由到/MyApp/signalr/negotiate.

I tried the other way around (change the MapSignalR to the /signalr path) but this did not work and the negotiation was still routed to /MyApp/signalr/negotiate.
