SignalR跨域和IIS 7.5的路径集线器只能在本地服务器上，如何从外部访问呢？ [英] SignalR cross domain and IIS 7.5 path to hub only works locally on the server, how to access it externally?

问题描述

我自托管我的C＃的WinForms应用程序中的SignalR集线器服务器：

I am self hosting a SignalR Hubs server within my C# WinForms application:

        string url = "http://localhost:8081/";

        m_signalrServer = new Microsoft.AspNet.SignalR.Hosting.Self.Server(url);

        // Map the default hub url (/signalr)
        m_signalrServer.MapHubs();

        // Start the SignalRserver
        m_signalrServer.Start();   

我的ASP.NET Web应用程序充当SignalR集线器JavaScript客户端：

My ASP.NET web application is acting as the SignalR Hubs JavaScript client:

<script type="text/javascript" src="/Scripts/jquery.signalR-1.0.0-alpha2.min.js"></script>
<script type="text/javascript" src="http://localhost:8081/signalr/hubs"></script>
<script type="text/javascript" language="javascript">
    $(document).ready(function() {
        $.connection.hub.url = 'http://localhost:8081/signalr'

        var myHub = $.connection.myHub;

        $.connection.hub.error(function () {
            console.log("Error!");
        });

        $.connection.hub.start()
        .done(function () {
            console.log("Connected!");
        })
        .fail(function () { console.log("Could not connect!"); });           
    });   
</script>

这code正常工作时，我使用的是服务器的Web浏览器，因为它可以访问的http：//本地主机：8081 / signalr /集线器。

This code works properly when I am using the Server's web browser as it can access http://localhost:8081/signalr/hubs.

但是，当您浏览网站通过外部的http：// SERVERIP 中，SignalR因为jQuery脚本正在寻找 HTTP失败//本地主机：8081 / signalr （我相信它会在您的本地计算机上）

However, when you browse the site externally via http://serverip, the SignalR fails because the JQuery script is looking for a http://localhost:8081/signalr (which I believe it looks for on your local computer).

我已经改变了：

$.connection.hub.url = 'http://serverip:8081/signalr'

和我启用了8081网站的浏览，并可以通过 HTTP浏览到网站：// SERVERIP：8081 。然而，浏览到的http：// SERVERIP：8081 / SignalR /集线器找不到枢纽文件可从的http：//本地主机： 8081 / siganlr /集线器。

and I enabled browsing of the website on 8081 and can browse to the website via http://serverip:8081. However, browsing to http://serverip:8081/SignalR/Hubs can not find the hub file that is available from http://localhost:8081/siganlr/hubs.

此外，作为一个测试我启用SignalR通过App_Start文件夹中的ASP.NET Web应用程序中 - > RegisterHubs.cs文件： RouteTable.Routes.MapHubs（）;

Also, as a test I enabled SignalR within the ASP.NET web application via the App_Start folder -> RegisterHubs.cs file : RouteTable.Routes.MapHubs();

这样做使我能够浏览到的http：// SERVERIP：8081 / signalr /集线器或的http：// SERVERIP / signalr /集线器，我可以看到由ASP.NET网站所产生的枢纽。这不是我想要的，因为这不是我从我的C＃WinForms应用程序托管中心。

Doing this allows me to browse to http://serverip:8081/signalr/hubs or http://serverip/signalr/hubs and I can see the hubs being generated by the ASP.NET website. This is not what I want because this is not the hubs I am hosting from my C# WinForms application.

再次，浏览到的http：// SERVERIP：8081 / signalr /集线器没有找到signalr或上存在枢纽文件 HTTP ：//本地主机：8081 / signalr /集线器。有谁知道我怎样才能使这个文件提供给我的ASP.NET Web应用程序，这样我可以让SignalR外部工作？

Once again, browsing to http://serverip:8081/signalr/hubs does not find signalr or the hubs file that exists on http://localhost:8081/signalr/hubs. Does anyone know how I can make this file available to my ASP.NET web application so that I can make SignalR work externally?

编辑：我忘了提8081是服务器防火墙上打开

I forgot to mention 8081 is open on the server firewall.

推荐答案

将其更改为：

string url = "http://*:8081/";

m_signalrServer = new Microsoft.AspNet.SignalR.Hosting.Self.Server(url);
