C# complete dynamic deserializer to dictionary about msgpack-cli HOT 15 CLOSED

Changed handler adressing, but still doesnt work for me.

    Dictionary<MessagePackObject, MessagePackObject> mpoDict = MessagePackSerializer.Create<Dictionary<MessagePackObject, MessagePackObject>>().Unpack(new MemoryStream(rawMessage));
    Dictionary<String, MessagePackObject> dict = mpoDict.ToDictionary(kv => (String)kv.Key, kv => kv.Value);
    MessagePackObject theValue;

    if (dict.TryGetValue("error", out theValue))
    {
        var error = (String)theValue;
    }
    else if (dict.TryGetValue("engine", out theValue))
    {
        var engine = (String)theValue;
        if(engine.Equals("@LOGIN")){Server.Client.Handler.LoginHandler(dict)}
        else if(engine.Equals("@REGISTER")){Server.Client.Handler.RegisterHandler(dict)}
        else if(engine.Equals("@MESSAGE")){Server.Client.Handler.MessageHandler(dict)}
        else if(engine.Equals("@LOGOUT")){Server.Client.Handler.LogoutHandler(dict)}
        else{Server.Clinet.Handler.ErrorHandler.throwError("Unrecognized Engine")}
    }
}

Could you use MessagePackObjectDictionary to represents dynamic message? Its built-in serializer now can handle nested dynamic element, so it might solve your problem.

MessagePackObjectDictionary mpoDict = MessagePackSerializer.Create<MessagePackObjectDictionary>().Unpack(new MemoryStream(rawMessage));
// or, you can simply do as following:
// var mpoDict = Unpacking.UnpackDictionary(rawData).Value;

thanks for the fast reply :)
Seems to work for me :) but i dont really like the try and Error thing :(

from msgpack-cli.

Do you say that you want to ensure exact solution, or hope to improve documents in the first place? If former, please tell me expected & actual issue you faced. If latter, I will be happy if you told me what content did you like to see.
As a first step of latter, I updated wiki to publish sample codes.

Something like a package header would be awesome, so that the package destination can be instantly assigned and the payload transmitted to the class, which is working with it, so you can avoid the try&error stuff

from msgpack-cli.

I might misunderstand what the 'try&error' means. Do you mean that an ability to embed a kind of 'type hint' in the packed bytes to reduce hand-made detection of actual type like if statements in your code?

from msgpack-cli.

yeah exactly all the if statements are problematic. The app is managed with a massresponse servernetwork, but this network don't have unlimited CPU, too. So creating the dict, gettin one var of it, "try&error" it out, till you find what you are looking for or sorting it out, cause of malformed package.

from msgpack-cli.

Then transmit to the subengine, which evaluates the rest of the package etc. etc.

from msgpack-cli.

it would be more useful to have a so called package header, which don't need the creation of a dict and so on. So data can be evaluated in few less steps and cpu&RAM would be saved. I do not want to work with googlestuff but if you are interested in packageheaders, there is a extension called protobuf supporting exact these headers. Is it implementable here?

from msgpack-cli.

I see. I'll study the extension of protobuf and tuckle to dynamic type with existing msgpack ext types.

from msgpack-cli.

nice. We would really like to use your Packageformat in our App :)

@Jan-Heapster I released this feature in 0.6.0-beta2 release. Could you try it?

from msgpack-cli.

Fixed in 0.6.0.
