ios - 在 Swift 中调用 SignalR 方法 (SwiftR)

Question

我想在我的项目中使用 SignalR，我对在 swift 中使用 signalR 一无所知，我正在安装 SwiftR pod，但我不知道如何调用 webService 方法，将参数传递给 webService 并获取 JSON 结果来自 webService，有我的简单代码用于连接到 webService 并开始连接，但一切都错了，连接不成功。这是网址:✿ http://s.ne ***y.ir/这是应该调用的方法: Authentication_Code_Request(string Mobile, byte Method)方法是 10 或 20我应该得到这样的回应:信息方法代码发件人

这是我的代码:

var autHub: Hub!
    var connection: SignalR!
    //var name: String!

@IBAction func sendRequest(_ sender: Any) {

         connection = SignalR("http://s.ne***y.ir/")
        connection.signalRVersion = .v2_2_0

        print(connection.baseUrl)

        var methodString: String?
        methodString = "10"
        chatHub = Hub("autHub")
        chatHub.on("Authentication_Code_Request") { [weak self] args in
            if let mobile = args?[0] as? String, let method = args?[1] as? String, let mobiletext = self?.chatTextView.text, let mehodText = methodString {
                print(method)
                print(mobiletext)
                print(mehodText)
                print(mobile)
            }
        }
        connection.addHub(chatHub)

        connection.starting = { [weak self] in

            self?.button.tintColor = #colorLiteral(red: 0.2745098174, green: 0.4862745106, blue: 0.1411764771, alpha: 1)
        }

    }

这是 SignalR objective C，使用 Bridging-Header 在 Swift 中使用

首先，安装Pod

pod 'SignalR-ObjC'

============================================= ========

添加 objective-c 类名称 SignalRClassViewController.h 和 SignalRClassViewController.m

@interface SignalRClassViewController : UIViewController<SRConnectionDelegate, SRHubConnectionInterface, SRClientTransportInterface>


// This method is used to have Single Instance. In the whole app, Life cycle makes sure you are using only one Instance of SignalR Class because of it one to one connection so we need listeners which continue to listen each time.
