swift - 快速实现socket.io-client

Question

我正在尝试快速实现socket.io-client。它没有按预期工作。我无法读取服务器对我的请求的任何响应。我的套接字正在连接，但之后我无法调用事件并获得它们的响应。 Swift 4、Xcode 10

我使用全局类将套接字函数声明为“clsGlobal”，并在不同的 View Controller 中调用套接字函数。

导入基础导入 UIKit导入SocketIO

clsSocket 类:NSObject {

let appdelegate = UIApplication.shared.delegate as! AppDelegate

static var manager = SocketManager(socketURL: URL(string: "my url")!, config: [.log(true), .reconnects(true)])
static var socket = manager.defaultSocket

static func ConnectSocket(){


    socket.connect()
    print(socket.status)

    socket.on("locationsUpdate", callback: { data,ack in
        print(data)
        let resp = data[0] as! Any
        print(resp)
    })
}
static func updateLocation(dId:NSNumber, uId:NSNumber, distance:Double){
    let datafield : [String:Any] = ["id":dId,
                                    "userid": uId,
                                    "travelledDistance":distance
    ]
    let data = try? JSONSerialization.data(withJSONObject: datafield)
    if socket.status == .connected {
        socket.emit("updateLocation",  data!)
        socket.emit("requestLocations")
    }

}
static func dogDisconnect(dogid:NSNumber, userid:NSNumber){
    let datafield = ["dId":did, "uId":userid]
    let dataobj = try? JSONSerialization.data(withJSONObject: datafield)
    socket.emit("disconnect",  dataobj!)
    socket.disconnect()
    socket.off("requestLocations")
}

}

如何知道服务器是否已连接以及如何打印服务器的响应？

我已经为套接字类创建了一个全局

import SocketIO

class SocketHelper {

    static let shared = SocketHelper()
    var socket: SocketIOClient!

    let manager = SocketManager(socketURL: URL(string: AppUrls.socketURL)!, config: [.log(true), .compress])

    private init() {
        socket = manager.defaultSocket
    }

    func connectSocket(completion: @escaping(Bool) -> () ) {
        disconnectSocket()
        socket.on(clientEvent: .connect) {[weak self] (data, ack) in
            print("socket connected")
            self?.socket.removeAllHandlers()
            completion(true)
        }
        socket.connect()
    }

    func disconnectSocket() {
        socket.removeAllHandlers()
        socket.disconnect()
        print("socket Disconnected")
    }

    func checkConnection() -> Bool {
        if socket.manager?.status == .connected {
            return true
        }
        return false

    }

    enum Events {

        case search

        var emitterName: String {
            switch self {
            case .searchTags:
                return "emt_search_tags"
            }
        }

        var listnerName: String {
            switch self {
            case .search:
                return "filtered_tags"
            }
        }

        func emit(params: [String : Any]) {
            SocketHelper.shared.socket.emit(emitterName, params)
        }

        func listen(completion: @escaping (Any) -> Void) {
            SocketHelper.shared.socket.on(listnerName) { (response, emitter) in
                completion(response)
            }
        }

        func off() {
            SocketHelper.shared.socket.off(listnerName)
        }
    }
}

使用方法

使用此代码连接套接字

SocketHelper.shared.connectSocket { (success) in

}

开始监听事件

SocketHelper.Events.search.listen { [weak self] (result) in
    // print(result[0])
}

发出事件

SocketHelper.Events.search.emit(params: <--Your Params-->)
