Question

我看了几个重叠的演示，但是我无法获得基本的发射功能。我收到与服务器文件的连接消息，但没有尝试从客户端发出。这是我在每个文件中的内容：

SocketIOManager.swift

import UIKit

class SocketIOManager: NSObject {

    static let sharedInstance = SocketIOManager()

    override init() {
        super.init()
    }

    var socket: SocketIOClient = SocketIOClient(socketURL: NSURL(string: "myURL")! as URL)

    func establishConnection() {
        socket.connect()
    }


    func closeConnection() {
        socket.disconnect()
    }

    func testSocket() {
        socket.emit("test")
    }

}

AppDelegate.swift

func applicationDidEnterBackground(_ application: UIApplication) {
   SocketIOManager.sharedInstance.closeConnection()
}

func applicationDidBecomeActive(_ application: UIApplication) {
   SocketIOManager.sharedInstance.establishConnection()

}

的ViewController

override func viewDidLoad() {
        super.viewDidLoad()      
        SocketIOManager.sharedInstance.testSocket()
    }

index.js服务器文件

io.on('connection', function(clientSocket){
  console.log('a user connected');


  clientSocket.on('disconnect', function(){
    console.log('user disconnected');
    });

  clientSocket.on("test", function(){
    console.log('test')
  });

});

所以再次，当我得到连接和断开的打印语句时，我没有得到任何常规发射函数。

请尝试更新index.js

由此

io.on('connection', function(clientSocket){
  console.log('a user connected');


  clientSocket.on('disconnect', function(){
    console.log('user disconnected');
    });

  clientSocket.on("test", function(){
    console.log('test');
  });

});

因为)的末尾缺少disconnect。

无法使基本的socket.io与Swift一起工作
