StompClientLib

## Introduction

StompClientLib is a stomp client in Swift. It uses Facebook's SocketRocket as a websocket dependency. SocketRocket is written in Objective-C but StompClientLib's STOMP part is written in Swift and its usage is Swift. You can use this library in your Swift 5+, 4+ and 3+ projects.

This is original a fork from AKStompClient (This library is not working right now)

Installation

StompClientLib is available through CocoaPods. To install it, simply add the following line to your Podfile:

Cocoapods

pod "StompClientLib"

Carthage

github "WrathChaos/StompClientLib"

Usage

import StompClientLib

Once imported, you can open a connection to your WebSocket server.

var socketClient = StompClientLib()
let url = NSURL(string: "your-socket-url-is-here")!
socketClient.openSocketWithURLRequest(request: NSURLRequest(url: url as URL) , delegate: self)

After you are connected, there are some delegate methods that you need to implement.

StompClientLibDelegate

stompClientDidConnect

func stompClientDidConnect(client: StompClientLib!) {
print("Socket is connected")
// Stomp subscribe will be here!
socketClient.subscribe(destination: topic)
// Note : topic needs to be a String object
}

stompClientDidDisconnect

func stompClientDidDisconnect(client: StompClientLib!) {
print("Socket is Disconnected")
}

didReceiveMessageWithJSONBody ( Message Received via STOMP )

Your json message will be converted to JSON Body as AnyObject and you will receive your message in this function

func stompClient(client: StompClientLib!, didReceiveMessageWithJSONBody jsonBody: AnyObject?, akaStringBody stringBody: String?, withHeader header: [String : String]?, withDestination destination: String) {
print("Destination : \(destination)")
print("JSON Body : \(String(describing: jsonBody))")
print("String Body : \(stringBody ?? "nil")")
}

didReceiveMessageWithJSONBody ( Message Received via STOMP as String )

Your json message will be converted to JSON Body as AnyObject and you will receive your message in this function

func stompClientJSONBody(client: StompClientLib!, didReceiveMessageWithJSONBody jsonBody: String?, withHeader header: [String : String]?, withDestination destination: String) {
  print("DESTINATION : \(destination)")
  print("String JSON BODY : \(String(describing: jsonBody))")
}

serverDidSendReceipt

If you will use STOMP for in-app purchase, you might need to use this function to get receipt

func serverDidSendReceipt(client: StompClientLib!, withReceiptId receiptId: String) {
  print("Receipt : \(receiptId)")
}

serverDidSendError

Your error message will be received in this function

func serverDidSendError(client: StompClientLib!, withErrorMessage description: String, detailedErrorMessage message: String?) {
  print("Error Send : \(String(describing: message))")
}

serverDidSendPing

If you need to control your server's ping, here is your part

func serverDidSendPing() {
  print("Server ping")
}

How to subscribe and unsubscribe

There are functions for subscribing and unsubscribing. Note : You should handle your subscribe and unsubscibe methods ! Suggestion : Subscribe to your topic in "stompClientDidConnect" function and unsubcribe to your topic in stompClientWillDisconnect method.

socketClient.subscribe(destination: topic)
// Note : topic needs to be a String object

Unsubscribe

socketClient.unsubscribe(destination: topic)

Important : You have to send your destination for both subscribe or unsubscribe!

Unsubsribe with header

let destination = "/topic/your_topic"
let ack = destination
let id = destination
let header = ["destination": destination, "ack": ack, "id": id]

// subscribe
socketClient?.subscribeWithHeader(destination: destination, withHeader: header)

// unsubscribe
socketClient?.unsubscribe(destination: subsId)

Auto Reconnect with a given time

You can use this feature if you need to auto reconnect with a spesific time or it will just try to reconnect every second.

// Reconnect after 4 sec
socketClient.reconnect(request: NSURLRequest(url: url as URL) , delegate: self as StompClientLibDelegate, time: 4.0)

Auto Disconnect with a given time

// Auto Disconnect after 3 sec
socketClient.autoDisconnect(time: 3)

Login Passcode Implementation

This is just an example. You need to convert to your implementation. #42

let connectFrame = "CONNECT\n login:admin\n passcode:password\n\n\n\0"
socket.write(string: connectFrame)
