我有一个SignalR Windows服务客户端正在调用一个MVC应用程序SignalR集线器上的方法,当它全部是localhost时正在工作。当我将MVC应用程序部署到真实服务器时,我得到404个错误,我不知道该做什么或如何解决。
客户:
protected override async void OnStart(string[] args)
{
eventLog1.WriteEntry("In OnStart");
try
{
var hubConnection = new HubConnection("http://somesplace.com/AlphaFrontendServer/signalr", useDefaultUrl: false);
IHubProxy alphaProxy = hubConnection.CreateHubProxy("AlphaHub");
await hubConnection.Start();
await alphaProxy.Invoke("Hello", "Message from Service");
}
catch (Exception ex)
{
eventLog1.WriteEntry(ex.Message);
}
}
服务器代码是:
public class AlphaHub : Hub
{
public void Hello(string message)
{
// We got the string from the Windows Service
// using SignalR. Now need to send to the clients
Clients.All.addNewMessageToPage(message);
// Send message to Windows Service
}
和
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
ConfigureAuth(app);
app.MapSignalR("/signalr", new HubConfiguration());
}
}
当一切都是localhost时,正在调用Hello方法。现在它生成404错误:
