Connect to remote server
Hello, For some reason, i cannot connect socket.io to a remote server. When using localhost it worked fine, but when switching, nothing happens.
Any help?
Did you add the right port number when you are creating instance of the SocketIOClient?
+1 - same for me, tried using it in a fresh sample project in view did load or in viewcontroller method
func connectSocket() {
let mySocket = SocketIOClient(socketURL: "\(CurrentConfiguration.serverURL)")
mySocket.connect()
mySocket.onAny{println("got event: \($0.event) with items \($0.items)")}
mySocket.on("connect") {data, ack in
println("socket connected")
}
}
@longbowww That socket object is scoped to that function, once it leaves it will be released. You need to make the socket a property of an object.
@longbowww hey I have the same issue did you declare as var ? let mySocket = SocketIOClient(socketURL: "(CurrentConfiguration.serverURL)") outside the function ?
public func scala_init(host: String, uuid: String, secret: String, token: String) -> Promise<Bool> { return Promise { fulfill, reject in hostUrl=host Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = ["Authorization": token]; //socket connection // socket = SocketIOClient(socketURL: "test.test.com:9000", options: [String : AnyObject]?()) socket.on("connect") {data, ack in println("socket connected") fulfill(true) } socket.connect() } } @nuclearace How can I do this by passing the host??
@cesar-oyarzun-m i ended up doing the socket connect in a view controller and declare "var socket" in it
var socket = SocketIOClient(socketURL: "\(CurrentConfiguration.serverURL)", opts: [
"reconnects": true,
"reconnectAttempts": 5,
"reconnectWait": 5,
"nsp": "me",
"forceWebsockets": true,
"log":false
])
override func viewDidLoad() {
super.viewDidLoad()
self.configureSocket()
}
func configureSocket() {
self.socket.on("connect") {data, ack in
println("socket connected")
}
self.socket.onAny {
println("Got event: \($0.event), with items: \($0.items)")
}
//whatever socket.on events you wanna have here
self.socket.connect()
}
@cesar-oyarzun-m its just a String from another class https://serverUrl.com:port
@longbowww mmm I'm trying to make this dynamic not static, the host will be received as parameter in the method. I have this code it doesnt work
public final class ScalaSocket: NSObject {
var socket = SocketIOClient(socketURL: "test.server.com:9000", options: ["log": true])
public func start_socket(){
self.socket.on("connect") {data, ack in
println("socket connected")
}
self.socket.connect()
}
}
I'm calling this from other method
public func scala_init(host: String, uuid: String, secret: String, token: String) -> Promise<Bool> {
return Promise { fulfill, reject in
var scalaSocket = ScalaSocket()
scalaSocket.start_socket()
}
}
Your scoping is wrong. scalaSocket is getting released inside the promise closure.
Hey @nuclearace I'm trying to pass the socket object to other object, but I think the scope is only for one class, I have this
public class TestSocket: NSObject {
public var socket = SocketIOClient(socketURL: hostUrl, options: ["log": false,"connectParams": ["token":tokenSDK]])
Then I have other class the inherit from the one that has the socket variable and I want to override the request method, but the emit doesn't work
public final class TestSystemCh: TestSocket {
override public func request(messageDic: Dictionary<String, String>) -> Promise<Any> {
var dic:Dictionary<String,String> = messageDic as Dictionary
dic.updateValue("system", forKey: "channel")
let requestPromise = Promise<Any> { fulfill, reject in
socket.emit(ScalaConfig.SOCKET_MESSAGE,dic)
var promiseDic = Dictionary<String,Any>()
promiseDic = [ "fulfill": fulfill,"reject":reject]
request.updateValue(promiseDic, forKey: uuid)
}
return requestPromise
}
}
Are you sure that the socket is connected when you're trying to emit? Also, you're writing some Objective-C looking Swift code
override public func request(var dic: [String: String]) -> Promise<Any> {
dic["channel"] = "system"
let requestPromise = Promise<Any> { fulfill, reject in
socket.emit(ScalaConfig.SOCKET_MESSAGE,dic)
var promiseDic = Dictionary<String,Any>()
promiseDic = [ "fulfill": fulfill,"reject":reject]
request.updateValue(promiseDic, forKey: uuid)
}
return requestPromise
}
If it is connected, it's probably some scope problem again
@nuclearace I'm doing this on Swift code and socket is not connected if I ask on the child class, I understand must me a scope problem, but I don't know how to solved, Do I have to create child with the socket as var or pass as parameter?
