所以我遇到了一个问题，我的Swift/Xcode文件告诉我已经连接到服务器，而我的节点文件没有告诉我终端中的“用户已连接”，这有点像是一个重新发布，但我没有很好地阐述原始问题，所以没有得到回复

我的节点文件如下所示：

const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http);
const port = process.env.PORT || 3000;

app.use(express.static(__dirname + '/public'));

function onConnection(socket){
  console.log('a user connected');
  socket.on('disconnect', onDisconnection);
}

function onDisconnection(socket){
  console.log('a user disconnected');
}

io.on('connection', onConnection);

http.listen(port, () => console.log('listening on port ' + port));

class PDSocketManager: NSObject {

class var shared: PDSocketManager {
    struct Static{
        static let instance = PDSocketManager()
    }
    return Static.instance
}

var socket: SocketIOClient?
fileprivate var manager: SocketManager?

fileprivate override init(){}

func establishConnection(_ completion: (() -> Void)? = nil) {
    let socketUrlString: String = "http://ip-address:3000"
    self.manager = SocketManager(socketURL: URL(string: socketUrlString)!, config: [.log(true), .reconnects(true), .extraHeaders(["header": "customheader"])])
    self.socket = manager?.defaultSocket
    self.socket?.connect()

    self.socket?.once(clientEvent: .connect, callback: { (data, emitter) in
        print("\n\n\n connection done!! \n\n\n")
        if completion != nil{
            completion!()
        }
    })
}

func connect()  {
    socket?.connect()
    print("socket connect")
}

func disconnect()  {
    socket?.disconnect()
}

func checkSocktConnect() -> Bool {
    if let myManager = self.manager{
        if myManager.status == SocketIOStatus.connected{
          return true
        } else {
            self.socket?.connect()
            return false
        }
    } else{
        return false
    }
    } }
我的雨燕看起来像：

const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http);
const port = process.env.PORT || 3000;

app.use(express.static(__dirname + '/public'));

function onConnection(socket){
  console.log('a user connected');
  socket.on('disconnect', onDisconnection);
}

function onDisconnection(socket){
  console.log('a user disconnected');
}

io.on('connection', onConnection);

http.listen(port, () => console.log('listening on port ' + port));

class PDSocketManager: NSObject {

        static let instance = PDSocketManager()

    self.socket = manager?.defaultSocket

    self.socket?.once(clientEvent: .connect, callback: { (data, emitter) in

        if completion != nil{
            completion!()
        }
    })
}

func connect()  {
    socket?.connect()
    print("socket connect")
}

func disconnect()  {
    socket?.disconnect()
}

            return false
        }
    } else{

您必须在Xcode中删除此项：

.version(.two)
安装SocketManager时。然后它就会起作用

我假设由于服务器上的Socket.io版本，它无法工作。我认为您在服务器端使用版本3，在客户端使用版本2（默认为版本3），所以它不会一起通信

您必须更新播客，如：

pod 'Socket.IO-Client-Swift'
然后pod安装

我删除了它，仍然是完全相同的错误。我会更新问题中的代码，因为我几天前更改了它，但忘了在这里更改代码。这很奇怪。我试过了，效果很好。您是否使用计算机的ip地址？是的，我正在使用计算机模拟终端上的服务器，将Xcode项目上载到我的iPhone，并在按下按钮时运行establishConnection（）函数。我也可以和你聊天/聊天，以便更好地解释和发送所有事情的截图是的，请给我一个解决问题的机会。请不要通过破坏你的帖子为其他人做更多的工作。通过在Stack Exchange网络上发布，您已授予Stack Exchange在下不可撤销的权利，以分发该内容（即，无论您未来的选择如何）。根据堆栈交换策略，帖子的非破坏版本是分发的版本。因此，任何故意破坏行为都将恢复原状。如果您想了解有关删除帖子的更多信息，请参阅：
