【问题描述】：

当我运行此代码时，没有迹象表明 XMPPController 已连接到 Ejabberd 服务器。 XMPPStreamDelegate 方法也没有被调用。就好像代码甚至不存在一样。应该有一些迹象表明我不应该在那里连接？其他人有这个问题吗？这是我的代码。谢谢。

XMPPController 类：

import Foundation
import XMPPFramework

enum XMPPControllerError: Error 

case wrongUserJID



class XMPPController: NSObject 

var xmppStream: XMPPStream

let hostName: String
let userJID: XMPPJID
let hostPort: UInt16
let password: String

init(hostName: String, userJIDString: String, hostPort: UInt16, password: String) throws 
    guard let userJID = XMPPJID(string: userJIDString) else 
        throw XMPPControllerError.wrongUserJID
    


    self.hostName = hostName
    self.userJID = userJID
    self.hostPort = hostPort
    self.password = password

    self.xmppStream = XMPPStream()
    self.xmppStream.hostName = hostName
    self.xmppStream.hostPort = hostPort
    //self.xmppStream.startTLSPolicy = XMPPStreamStartTLSPolicy.allowed
    self.xmppStream.enableBackgroundingOnSocket = true
    self.xmppStream.myJID = userJID


    super.init()
    self.xmppStream.addDelegate(self, delegateQueue: DispatchQueue.main)







func connect() 


    if !self.xmppStream.isDisconnected() 
        return
    

    do 

        try self.xmppStream.connect(withTimeout: 5)

     catch 

        print("ERROR CONNECTING")

    





extension XMPPController: XMPPStreamDelegate 


func xmppStreamDidConnect(_ sender: XMPPStream!) 
    print("Stream: Connected")
    try! sender.authenticate(withPassword: self.password)


func xmppStreamDidAuthenticate(_ sender: XMPPStream!) 
    self.xmppStream.send(XMPPPresence())
    print("Stream: Authenticated")

AppDelegate（用于测试 XMPPController）

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate 

var window: UIWindow?
var xmppController: XMPPController!

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
    // Override point for customization after application launch.

    try! self.xmppController = XMPPController(hostName: "192.168.0.33", userJIDString: "admin@192.168.0.33", hostPort: 5221, password: "password")



    return true


func applicationWillResignActive(_ application: UIApplication) 



func applicationDidEnterBackground(_ application: UIApplication) 



func applicationWillEnterForeground(_ application: UIApplication) 



func applicationDidBecomeActive(_ application: UIApplication) 



func applicationWillTerminate(_ application: UIApplication) 

无论出于何种原因，这都不起作用。

【参考方案1】：

您的 ejabberd 服务器是否正常工作。您可以通过运行 ./ejabberdctl status 检查 ejabberd 服务器的状态。另外，你能检查一下 ejabberd 日志吗？检查您的 ejabberd 是否配置正确和工作的一个好方法是使用 Adium 登录到您的 ejabberd 服务器。

检查这部分代码中端口是5222而不是5221

try! self.xmppController = XMPPController(hostName: "192.168.0.33", userJIDString: "admin@192.168.0.33", hostPort: 5221, password: "password")

如果 5221 正确，你应该调用函数 connect()。

self.xmppController.connect()

连接
