我试图使用SignalR与跨域,但我在调用启动函数时收到错误消息.错误信息是"Uncaught TypeError: Cannot call method 'start' of undefined "
我正在使用代码服务器端:
[assembly: OwinStartup(typeof(SignalRChat.Startup))]
namespace SignalRChat
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/signalr", map =>
{
map.UseCors(CorsOptions.AllowAll);
var hubConfiguration = new HubConfiguration
{
EnableJSONP = true
};
map.RunSignalR(hubConfiguration);
});
}
}
}
客户端代码.
