Didconnect function cannot be callback after successful connection

[yongjunta]

When the connection with the server is successful, the console also prints WebSocket is connected, but there is no callback to stompClientDidConnect method, why?

Hello @yongjunta,
Thank you so much for using the lib and create an issue about it :)
This library is more than 2 years old therefore, I did not need a callback method for stompClientDidConnect method. Also, I believe that people can create a business logic with this protocol method.
Of course, PR's are welcome for this little feature :)

Hello, what I want to ask is whether I automatically enter the StompClientDidConnect method when the connection with the server is successful. The subscription method I wrote in the StompClientDidConnect method has not been executed. It should be that I did not enter the StompClientDidConnect method at all. What should we do in this case? I hope you can give me Demo. Thank you!

I am having the same issue ... ...

Here's what i did:

In my viewDidLoad(), I put
socketClient.openSocketWithURLRequest(request: NSURLRequest(url: url as URL) , delegate: self as StompClientLibDelegate)

it never reaches the method stompClientDidConnect :
func stompClientDidConnect(client: StompClientLib!) { print("Socket is Connected : ") socketClient.subscribe(destination: "/user/topic/greetings") socketClient.subscribe(destination: "/user/topic/finish") socketClient.autoDisconnect(time: 5) // Reconnect after 4 sec socketClient.reconnect(request: NSURLRequest(url: url as URL) , delegate: self as StompClientLibDelegate, time: 4.0) }

I did some debugging. In StompClientLib.sendFrame(), it always goes into the if statement:

if socket?.readyState == .OPEN { socket?.send(frameString) } else { if let delegate = delegate { DispatchQueue.main.async(execute: { delegate.stompClientDidDisconnect(client: self) }) } }
and skip the else... ... So it never reached my delegate method.

I guess in order to make it work it needs this commit:

https://github.com/WrathChaos/StompClientLib/commit/ba521b4ddd32ce48fa63d00439c76af8b165d673

specifically this line // Support for Spring Boot 2.1.x connectionHeaders = [StompCommands.commandHeaderAcceptVersion:"1.1,1.2"] is needed for spring boot. If you're also using it that could fix it

Hello @yhz82415,
That commit is the latest version of the StompClientLib, did it solve your issue ?

[yongjunta]

The problem I encountered was not Springboot's reason. He entered the if statement to judge whether the connection was disconnected. We just need to activate DidConnect's method under the connection method in the webSocket DidOpen method and subscribe to DidConnect's method. like this : public func webSocketDidOpen(_ webSocket: SRWebSocket!) { print("WebSocket is connected") connect() DispatchQueue.main.async(execute: { [weak self] in self?.delegate?.stompClientDidConnect(client: self) }) }

@yongjunta, which version are you working on?

[yongjunta]

The swift 4.2 I used at the time

[yongjunta]

1.2.7，The swift 4.2 I used at the time

[WrathChaos]

Can you try 1.3.0 version with Swift 4.2? It should have been supported with the latest version.

Is the latest version 1.3.0? If so there are 3 commits in that version but doesn't have the commit for spring boot support ba521b4 . 1.3.0...master

@yongjunta, still waiting for you to close this issue :)

@WrathChaos Hi there. I did checkout version 1.3.1 but I don't see the below commit
https://github.com/WrathChaos/StompClientLib/commit/ba521b4ddd32ce48fa63d00439c76af8b165d673
After testing with this commit, it's working now :)

[WrathChaos]

Good to hear @duannl :)
