B4i Library iWebSocket

A WebSocket client implementation. This library is based on this open source project:
https://github.com/square/SocketRocket

The API is the same as B4A WebSocket library. The WebSocketHandler class which is used to connect to B4J WebSocket servers is included in the example.
See this link for more information: https://www.b4x.com/android/forum/threads/websocket-client-library.40221/#content


Edit: the library is already included in the IDE.

Thank you Erel and Merry Christmas !

the exemple is for b4A not b4i.
could you post exemple for b4i please

 

[Erel]

Which example?

 

[narek adonts]

B4i-websocketclient.zip

 

[Erel]

Fixed. I've uploaded the correct file to the first post.

I saw on inet that SocketRocket support sending data instead of string.
Is there a way to be able to send files with Websocket with b4i ?

 

[Erel]

It is possible with NativeObject. However what is connected in the other side?

 

[narek adonts]

B4J jServer

 

[Erel]

B4J WebSocket handlers work with text messages only.

You should instead create another regular handler that will handle the files (there are several examples for this).

I know but I was thinking to implement a Chat service with photo/video sharing in my app with websockets as I think regular handlers are not so suitable for this.
Will be great to be able to receive bytes data with b4j jServer.
Now I am thinking to mix websockets with MQTT. So to initialize a connection I think to use a websocket and for the rest MQTT. What do you think? The only thing that I dont know how to handle are the offline messages.

Why not? They are more suitable for this than websockets.

Hard to say without understanding your requirements...

Regular Messenger like Facebook Messenger, Whatsapp.

Could you advise how to handle offline messages with MQTT?

 

[Erel]

Please start a new thread for this question.

Now, our company have a project need to transfer Files between iOS/Android(programmed by B4i/B4A) and the Web Server (we use websocket.io with Node.js to build file server), is there other good library to transfer binary stream except iWebSocket? now I found iWebSocket only support string transfer.

 

[Erel]

There is no other websocket implementation. However you should use a regular handler to transfer the files. There is no advantage for websockets when transferring files.

Have you any suggestion what kind of library, implementation (or the so called handler) that can reach file transferring without any encoding method that will waste throughput and bandwidth.

 

[Erel]

You can transfer files with HttpUtils2. The overhead will be minimal.
