我无法连接到 Socket.IO 聊天..

import UIKit
import SocketIO

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let manager = SocketManager(socketURL: URL(string: "wss://socket-io-chat.now.sh/socket.io/")!, config: [.log(true), .compress])
        let socket = manager.defaultSocket

        socket.on(clientEvent: .connect) {data, ack in
            print("socket connected")
        }

        socket.on("new message") {data, ack in
            print("new Messages")
        }

        socket.connect()  
    }
}

我正在使用最新的 socket.io 库，并且已经在 info.plist 中添加了应用程序传输。

这就是日志所说的......

试试下面的代码：

var socketClient: SocketIOClient!

if let url = URL(string: "wss://socket-io-chat.now.sh/socket.io/") {
            let socketClient = SocketIOClient(socketURL: url, config: [.log(true),.forcePolling(true)])

            socketClient.connect()
        }


socketClient.onAny { (socEvent) in


if let status =  socEvent.items as? [SocketIO.SocketIOClientStatus] {
            if let first = status.first {
                switch first {
                case .connected:
                    print("Socket: connected")
                    break

                case .disconnected:
                    print("Socket: disconnected")
                    break
                case .notConnected:
                    print("Socket: notConnected")
                    break
                case .connecting:
                    print("Socket: connecting")
                    break
                }
             }
          }
        }
