It not able to connect web socket.

[hukusuke1007]

I have a problem. It not able to connect web socket.

■Source code.

let baseURL = "http://alice2.nem.ninja:7890" print("URL : (baseURL)") let url = NSURL(string: baseURL)! StompClientLib().openSocketWithURLRequest(request: NSURLRequest(url: url as URL) , delegate: self)

■Result

Is it need to set other parameter?? I want your advice.

Best regards.

Hello @hukusuke1007 , Are you sure about your server socket using the stomp??

[hukusuke1007]

@WrathChaos Yes. I heard that "http://alice2.nem.ninja:7890" is supported STOMP web socket. → I changed it to "http://alice2.nem.ninja:7778/w/messages/websocket". It's correct from this material(https://rb2nem.github.io/nem-dev-guide/07-monitoring-blockchain/).

But it not called override method.

・Additional infomation. I implemented it as follows. It not occur 404 error. But it not called override method(stompClientDidConnect). And i tried it in both iOS simulator and real machine. Is the usage of the your library correct?

import UIKit
import StompClientLib

class ViewController: UIViewController, StompClientLibDelegate {

    struct mySecretInfo {
        let adress:String = "NCH5JDPEAKA3CKQBSEPE4VIH53FQO4AU55XTVRPY"
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        RegisterSocket()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    public func RegisterSocket() {
        let baseURL = "http://alice2.nem.ninja:7778/w/messages/websocket"
        let completedWSURL = baseURL
        print("URL : \(completedWSURL)")
        let url = NSURL(string: completedWSURL)!
        let socketClient = StompClientLib()
        socketClient.openSocketWithURLRequest(request: NSURLRequest(url: url as URL) , delegate: self)
    }

    // ■ MARK: delegate.
    func stompClientDidConnect(client: StompClientLib!) {

        let info = mySecretInfo()
        // ■ Subscribe.
        let topic = "/account/mosaic/owned/" + info.adress
        print("Socket is Connected : \(topic)")
        client.subscribe(destination: topic)

@hukusuke1007 Okey, I will try to get data from your socket. Do I need any other information to connect your socket url?

[WrathChaos]

@hukusuke1007 Hello again, I've tried your url on the example and it works perfectly. Please delete

let wsURL = baseURL.prefix(7)
let completedWSURL = "ws://\(wsURL)gateway/websocket"
print("Completed WS URL : \(completedWSURL)")

These lines on the example and try it :) Give me a feedback please Have fun !

[hukusuke1007]

@WrathChaos I'm sorry for late. It successful to connect when I implemented a following source code. But no response when call SEND message(sendJSONForDict(dict: sendData as AnyObject, toDestination: sendTopic).

import UIKit

class ViewController: UIViewController, StompClientLibDelegate {

        socketClient_ = StompClientLib()

        RegisterSocket()
    }

        let url = NSURL(string: completedWSURL)!
        socketClient_.openSocketWithURLRequest(request: NSURLRequest(url: url as URL) , delegate: self)
    }

    // ■ MARK: delegate.

        let header = ["id":"0"]
        print("Subscrib : \(topic)")
