swift - 如何用swift语言实现Socket io

Question

这是我的socket io swift语言代码

和main.js文件代码也在这里

我不明白为什么不使用 socket io 服务器。

  let manager = SocketManager(socketURL: URL(string: "http://localhost:3000")!, config: [.log(true), .compress])
  self.socket = manager.socket(forNamespace: "/")
  establishSocketConnection()

  func establishSocketConnection() {

    self.socket.connect()
    self.socket.on("connection") { ( dataArray, ack) -> Void in
        print("connected to external server")

    }
  }

  func cloesSocketConnection() {
    self.socket.disconnect()
  }

Answer 1

你的套接字属性不是真的你的连接方式必须是这样的:

func establishSocketConnection() {
  let socket = manager.defaultSocket
      self.socket.on("connection") { ( dataArray, ack) -> Void in
    print("connected to external server")

     }
}

每次你想在套接字中创建处理程序时(比如 socket.on 或 socket.emit)您必须重新创建套接字变量。

希望对您有所帮助。
