在后端使用Swift和Node.js的Socket.io示例

Edu*_*ván 5 ios socket.io swift

我试图在iOS上使用Swift找到一个Socket.io实现的工作示例,但到目前为止还不走运.我确实从Github得到了一些例子,但每个都有一些问题,我不知道为什么它们不起作用.

有谁知道我可以在哪里获得一个开箱即用的工作示例,以便我可以通过代码并了解实现?

基于socket.io的示例:

服务器(index.js,请参阅socket.io网站进行设置):

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res){
    res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){
    socket.on('chat message', function(msg){
        io.emit('chat message', msg);
    });
});

http.listen(8080, function(){
   console.log('listening on *:8080');
});

客户端(ViewController.swift):

import UIKit
import Socket_IO_Client_Swift

class ViewController: UIViewController {

@IBOutlet weak var chatView:UITextView!
@IBOutlet weak var sendButton:UIButton!
@IBOutlet weak var sendField:UITextField!

let socket = SocketIOClient(socketURL: "10.0.0.1:8080", opts: ["log": true])

override func viewDidLoad() {
    super.viewDidLoad()

    addHandlers()
    self.socket.connect()
}

@IBAction func send() {
    self.socket.emit("chat message", withItems: [self.sendField.text!])
    self.sendField.text = ""
}

func addHandlers() {
    self.socket.on("connect") {data, ack in
        print("socket connected")
    }

    self.socket.on("chat message") {[weak self] data, ack in
        if let value = data.first as? String {
            self?.chatView.text?.appendContentsOf(value + "\n")
        }
    }
}

自从我提出这个问题以来,发生了一些变化,我们现在有了适用于 iOS 的 socket.io。这是关于它的原始博客文章:http ://socket.io/blog/socket-io-on-ios/
