vertx tcp eventbus client module for C#

TCP-eventbus-client-C~~#~~

This is a TCP eventbus implementation for C# clients. The protocol is quite simple:

        {
            public static void Main(string[] args){
             
             io.vertx.Eventbus eb=new io.vertx.Eventbus();
            
             Headers h=new Headers();
             h.addHeaders("type","maths");
             
             //body
             JObject body=new JObject();
             body.Add("message","add");
             
             //sending with time out = 5 secs
             eb.send(
                 "pcs.status",//address
                 body,//body
                 "pcs.status",//reply address
                 h, //headers
                 (new ReplyHandlers("pcs.status",//replyhandler address
                    new Action<bool,string>( //replyhandler function
                        (err,message)=>{
                            Console.WriteLine("replyhandler:"+message);
                        }
                    )
                 )
                ),
                5);//timeout
          }
        }

tcp-eventbus-client-c-sharp's Issues

consider using a logger

Errors are printed to STDOUT maybe using something like:

https://msdn.microsoft.com/en-us/library/microsoft.build.utilities.logger.aspx

would make more sense to use something like:

version

Hi,
thanks for your work.
I will try the eventbus, but I dont`t know which version I should use.
Can you give me a hint, which version is most stable?

best regards

use a json parser to avoid serialization/parsing errors:

Look into: DataContractJsonSerializer here is an example:

Feature Request

Hi Would it be possible for you to be able to adapt the code to connect to the sockjs bridge presented by vertx web?

1. Setup Vertx web.
2. Enable the socks bridge as per the documentation.
3. Connect your code to the raw web socket instead of to a TCP socket.
   e.g. ws://localhost:80/eventbus/websocket
   in the example eventbus can be anything. Basically the sockjs handler exposes a web socket that we can connect to directly and send messages over to the vertex event bus on the server.

This will mean one server exposing a single socket for web apps using sockJS client as well as any other connecting application e.g. .net using your code.

thanks.
