We have a .NET client, which use SignalR to call Server method, but the parameter seems very big, for such scenario how to fix it?
Client code:
public async Task FooAsync()
{
var hubConnection = new HubConnection(...);
await hubConnection.Start();
var hubProxy = hubConnection.CreateHubProcx("ValueHub");
//the content is very long, about 11776065 bytes (11MB)
var content = File.ReadAllText(...);
hubProxy.Invoke("Send", content);
...
}
Server code:
[HubName("ValueHub")]
public class ValueHub : Hub
{
public void Send(string json)
{
}
}
From the exception stack and source code, I found the SignalR internally use HttpClient with the FormUrlEncodedContent type HttpContent, and maybe the limitation came from here.
System.UriFormatException was unhandled
HResult=-2146233033
Message=Invalid URI: The Uri string is too long.
Source=System
StackTrace:
at System.UriHelper.EscapeString(String input, Int32 start, Int32 end, Char[] dest, Int32& destPos, Boolean isUriString, Char force1, Char force2, Char rsvd)
at System.Uri.EscapeDataString(String stringToEscape)
at System.Net.Http.FormUrlEncodedContent.Encode(String data)
at System.Net.Http.FormUrlEncodedContent.GetContentByteArray(IEnumerable`1 nameValueCollection)
at System.Net.Http.FormUrlEncodedContent..ctor(IEnumerable`1 nameValueCollection)
at Microsoft.AspNet.SignalR.Client.Http.DefaultHttpClient.Post(String url, Action`1 prepareRequest, IDictionary`2 postData, Boolean isLongRunning)
at Microsoft.AspNet.SignalR.Client.Transports.HttpBasedTransport.Send(IConnection connection, String data, String connectionData)
at Microsoft.AspNet.SignalR.Client.Transports.AutoTransport.Send(IConnection connection, String data, String connectionData)
at Microsoft.AspNet.SignalR.Client.Connection.Send(String data)
at Microsoft.AspNet.SignalR.Client.Hubs.HubProxy.Invoke[T](String method, Object[] args)
at Microsoft.AspNet.SignalR.Client.Hubs.HubProxy.Invoke(String method, Object[] args)
Any good suggestions over this problem?
