c# Signalr MessageSize默认是64K 大小,设为NULL即禁用这个限制 ,自己也可以按需求改为自己需要的大小

public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            //// 有关如何配置应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkID=316888
            ////设置可以跨域访问
            //app.UseCors (Microsoft.Owin.Cors.CorsOptions.AllowAll);
            ////映射到默认的管理
            ////var hubConfiguration = new HubConfiguration();
            ////hubConfiguration.EnableDetailedErrors = true;
            ////app.MapSignalR ("/signalr", hubConfiguration);
            //app.MapSignalR();

            app.Map("/signalr", map =>
            {
                // Setup the CORS middleware to run before SignalR.
                // By default this will allow all origins. You can
                // configure the set of origins and/or http verbs by
                // providing a cors options with a different policy.
                map.UseCors(CorsOptions.AllowAll);

                var hubConfiguration = new HubConfiguration
                {
                    EnableJSONP = true,
                    EnableJavaScriptProxies = true,
                    EnableDetailedErrors = true,

                    // You can enable JSONP by uncommenting line below.
                    // JSONP requests are insecure but some older browsers (and some
                    // versions of IE) require JSONP to work cross domain
                    // EnableJSONP = true
                };
                // Run the SignalR pipeline. We're not using MapSignalR
                // since this branch already runs under the "/signalr"
                // path.
                //最大数据量限制取消
                GlobalHost.Configuration.MaxIncomingWebSocketMessageSize = null;
                map.RunSignalR(hubConfiguration);
            });
        }
    }

默认数据缓冲区大小设置 GlobalHost.Configuration.DefaultMessageBufferSize = 1024
