如何使用跨域连接(CORS - 访问控制允许来源)与SignalR [英] How to use cross-domain connections (CORS - Access Control Allow Origin) with SignalR
问题描述
使用持久连接和ASP.NET JavaScript客户端,我尝试连接到与提供页面的子域不同的子域。
Using persistent connections and an ASP.NET JavaScript client, I am trying to connect to a sub-domain not the same as the one the page was served from.
ASP.NET页面从webserver sub1.mydomain.com
想要在 sub2.mydomain.com
连接到SignalR。
ASP.Net Page from webserver sub1.mydomain.com
wants to connect to SignalR at sub2.mydomain.com
. The same code works fine when connecting within the same sub-domain.
我发现了另一个使用了跨域连接的帖子:
I found another post where cross-domain connections were enabled with:
jQuery.support.cors = true;
但这对我没有用。
如何使用持久连接和JavaScript客户端连接到第二个子域中的SignalR?
How can I connect to SignalR in a second sub-domain using persistent connection and a JavaScript client?
推荐答案
请执行以下操作之一以使其工作:
You need to do one of the following to make it work:
- 设置
$。connection.hub.url ='http
-
在服务器上启用跨域:
- Set up
$.connection.hub.url = 'http://subdomain.domain.com/signalr';
, pointing to your subdomain. Enable cross domain on the server:
RouteTable.Routes.MapHubs(new HubConfiguration()
{
EnableCrossDomain = true
});
