ios - 如何在Socket.io Swift4中发出事件

我正在尝试在用户加入聊天室时发出事件。所以我有2节课：


SocketIOManager
ViewController


SocketIOManager代码：

import SocketIO

class SocketIOManager: NSObject {

    static let manager = SocketManager(socketURL: URL(string: "https://myurl.com:443")!, config: [.log(true), .compress])
    static let socket = manager.defaultSocket

    class func connectSocket(){
        self.manager.config = SocketIOClientConfiguration(
            arrayLiteral: .connectParams(["token": myToken), .secure(true)
        )
        socket.connect()
    }

    class func connectToChatRoom(chat: String, user: String){
        let jsonDic = ["chat": chat,
                       "user": user]

        print("CHEKING SOCKET CONNECTION 1-ST TIME - \(socket.status)") // This gives me - connecting

        socket.emit("join", jsonData)

        print("CHEKING SOCKET CONNECTION 2-ND TIME - \(socket.status)") // This gives me - connecting
    }

    class func isSocketConnected() -> Bool{
        if socket.status == .connected {
            return true
        }
        return false
    }
}

在ViewController中，我做-首先连接套接字。然后我试图发出。

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        SocketIOManager.connectSocket()
        SocketIOManager.connectToChatRoom(chat: chatID, user: myID)

        print("\(SocketIOManager.isSocketConnected())")  //This gives me "false"
    }
}

毕竟，我从Socket.IO的日志中收到错误：尝试在未连接时发出连接。

CHEKING SOCKET CONNECTION 1-ST TIME - connecting
2018-03-27 12:26:04.895072+0300 MyApp[3760:1940922] LOG SocketIOClient{/}: Handling event: error with data: ["Tried emitting join when not connected"]
CHEKING SOCKET CONNECTION 2-ND TIME - connecting
false

我在做发射吗？如何使用Socket.IO执行发射？

最佳答案

套接字在发出发射之前需要连接。为此，Socket.IO具有侦听器socket.on（“连接”）。因此，在建立状态连接后，我们可以发光。

socket.on("connect") { _, _ in
        print("socket connected")
        socket.emit("your_event", jsonObject)
    }
