在Swift中調用SignalR方法（SwiftR）

Question

我想在我的項目中使用SignalR，我不知道如何在swift中使用signalR，我安裝了SwiftR pod，但我不知道如何調用webService方法，將參數傳遞給webService並從webService獲取JSON結果，我的簡單代碼用於連接到webService並開始連接，但一切都是錯誤的，連接不成功。 這是URL：http://s.ne *** y.ir/ 這是方法應該調用： Authentication_Code_Request（串移動，字節方法） 方法是10或20 我應該得到這樣的響應： 消息 Method Code Sender

有我的代碼：

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) 
     } 

    }

這是使用橋接報頭

在夫特使用SignalR目標C

首先，安裝莢

莢 'SignalR-ObjC'

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

添加目標C類命名SignalRClassViewController.h和SignalRClassViewController.m
