问题描述
我遇到了如何在我的swift代码中实现websocket函数的问题。
I am in trouble how to implement websocket function to my swift code.
我已经完成了服务器实现和另一个javascript客户端。
他们运作良好。
所以，我相信websocket服务器没有错。
I have completed a server implementation and another javascript client. They are working well. So, I believe websocket server is not wrong.
但是如果我在swift中编写代码，它就不起作用了。没有错误发生，控制台上没有显示任何消息。
But if I write the code in swift, it don't work. No error happen and no message is shown on the console.
这是我的快捷代码。
import UIKit
import SocketIO
class ChatViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {
@IBOutlet weak var tableView: UITableView!
var bottomView: ChatRoomInputView!
var chats: [ChatEntity] = []
var socket: SocketIOClient!
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
// Initialize WebSocket
let manager = SocketManager(socketURL: URL(string: "http://example.com:8081")!, config: [.log(true), .compress])
socket = manager.defaultSocket
socket.on(clientEvent: .connect) {data, ack in
print("socket connected")
}
socket.on("server_to_client") {[weak self] data, ack in
print ("get Massage!!!")
}
socket.connect()
socket.emit("join_room", with: [getRegistrationId()])
socket.emit("client_to_server", with: ["ack_client"])
setupUI()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
}
override var canBecomeFirstResponder: Bool {
return true
}
override var inputAccessoryView: UIView? {
return bottomView
}
func setupUI() {
self.view.backgroundColor = UIColor(red: 113/255, green: 148/255, blue: 194/255, alpha: 1)
tableView.backgroundColor = UIColor(red: 113/255, green: 148/255, blue: 194/255, alpha: 1)
tableView.separatorColor = UIColor.clear
tableView.estimatedRowHeight = 10000
tableView.rowHeight = UITableViewAutomaticDimension
tableView.allowsSelection = false
tableView.keyboardDismissMode = .interactive
tableView.register(UINib(nibName: "YourChatViewCell", bundle: nil), forCellReuseIdentifier: "YourChat")
tableView.register(UINib(nibName: "MyChatViewCell", bundle: nil), forCellReuseIdentifier: "MyChat")
self.bottomView = ChatRoomInputView(frame: CGRect(x: 0, y: 0, width: self.view.frame.width, height: 60))
bottomView.chatTextField.delegate = self
bottomView.textSendButton.addTarget(self, action: #selector(self.chatTextSendButton(_:)), for: .touchUpInside)
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.chats.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let chat = self.chats[indexPath.row]
if chat.isMyChat() {
let cell = tableView.dequeueReusableCell(withIdentifier: "MyChat") as! MyChatViewCell
cell.clipsToBounds = true
// Todo: isRead
cell.updateCell(text: chat.text, time: chat.time, isRead: true)
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "YourChat") as! YourChatViewCell
cell.clipsToBounds = true
cell.updateCell(text: chat.text, time: chat.time, pic: RemoshinData.getDoctorPic())
return cell
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(indexPath)
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 10
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
func textFieldShouldClear(_ textField: UITextField) -> Bool {
return true
}
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
textField.inputFieldBorderBottom(color: Utils.getColor(),
x: textField.center.x,
y: textField.center.y,
w: textField.frame.size.width,
h: textField.frame.size.height)
bottomView.chatTextField = textField
return true
}
func textFieldShouldEndEditing(_ textField: UITextField) -> Bool {
textField.inputFieldBorderBottom(color: UIColor.lightGray,
x: textField.center.x,
y: textField.center.y,
w: textField.frame.size.width,
h: textField.frame.size.height)
return true
}
@objc func chatTextSendButton(_ sender: AnyObject) {
let chatText = bottomView.chatTextField.text!
if (chatText != "") {
let _mainViewController = MainViewController()
let jsonData = _mainViewController.sendChatText(_registration_id: getRegistrationId(), _chat_text: chatText)
if(jsonData["status"].string! == "success") {
socket.emit("client_to_server", with: ["update_chat"])
let chat = ChatEntity(text: jsonData["chat_text"].string!, time: "", userType: .I)
chats.append(chat)
tableView.reloadData()
bottomView.chatTextField.text = ""
}
}
}
}
我想在应用程序运行时在我的控制台上看到socket connected消息。我认为socket是错误的。但我不知道出了什么问题，因为没有找到错误信息。我怀疑我的info.plist中是否需要一些设置。但是，我怎么写都没有意义。
I want to see "socket connected" message on my console when the app run. I think the socket is something wrong. But I have no idea what is wrong because no error message found. And I doubt if I need some setting in my info.plist. But, I don't make sense how to write.
请给我一些建议？
推荐答案
var manager:SocketManager!
var socketIOClient: SocketIOClient!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
ConnectToSocket()
}
func ConnectToSocket() {
manager = SocketManager(socketURL: URL(string: "your url")!, config: [.log(true), .compress])
socketIOClient = manager.defaultSocket
socketIOClient.on(clientEvent: .connect) {data, ack in
print(data)
print("socket connected")
}
socketIOClient.on(clientEvent: .error) { (data, eck) in
print(data)
print("socket error")
}
socketIOClient.on(clientEvent: .disconnect) { (data, eck) in
print(data)
print("socket disconnect")
}
socketIOClient.on(clientEvent: SocketClientEvent.reconnect) { (data, eck) in
print(data)
print("socket reconnect")
}
socketIOClient.connect()
}
更新
在您的情况下： SocketManager：Manager正在发布
管理员保留通过管理器创建的套接字。所以至少，必须维护一个对管理器的强引用以使套接字保持活动状态。
Sockets created through the manager are retained by the manager. So at the very least, a single strong reference to the manager must be maintained to keep sockets alive.
[来自服务器的未知错误欢迎来到socket.io。]
["Got unknown error from server Welcome to socket.io."]
- 在服务器端和客户端检查socket.io版本，两者不匹配可能是导致此错误的原因
- 在info.plist（字典类型）和子键允许任意负载（布尔类型）中添加应用传输安全设置键是值。
