HTTP 502錯誤的網關C＃與poloniex上的瓦爾

Question

我想實時從Poloniex中檢索報價。他們使用wamp。我通過金塊WampSharp安裝，發現這個代碼：

static async void MainAsync(string[] args) 
    { 

     var channelFactory = new DefaultWampChannelFactory(); 
     var channel = channelFactory.CreateMsgpackChannel("wss://api.poloniex.com", "realm1"); 
     await channel.Open(); 

     var realmProxy = channel.RealmProxy; 

     Console.WriteLine("Connection established"); 

     int received = 0; 
     IDisposable subscription = null; 

     subscription = 
      realmProxy.Services.GetSubject("ticker") 
         .Subscribe(x => 
         { 
          Console.WriteLine("Got Event: " + x); 

          received++; 

          if (received > 5) 
          { 
           Console.WriteLine("Closing .."); 
           subscription.Dispose(); 
          } 
         }); 

     Console.ReadLine(); 
    } 

但在伺機channel.open不管（）我有以下錯誤：HHTP 502網關

你有一個想法，哪裏是問題

預先感謝您

Poloniex服務似乎無法處理如此多的連接。這就是爲什麼你會得到HTTP 502錯誤的網關錯誤。您可以嘗試使用重新連接機制以嘗試定期連接。

static void Main(string[] args) 
{ 
    var channelFactory = new DefaultWampChannelFactory(); 
    var channel = channelFactory.CreateJsonChannel("wss://api.poloniex.com", "realm1"); 

    Func<Task> connect = async() => 
    { 
     await Task.Delay(30000); 

     await channel.Open(); 

     var tickerSubject = channel.RealmProxy.Services.GetSubject("ticker"); 

     var subscription = tickerSubject.Subscribe(evt => 
     { 
      var currencyPair = evt.Arguments[0].Deserialize<string>(); 
      var last = evt.Arguments[1].Deserialize<decimal>(); 
      Console.WriteLine($"Currencypair: {currencyPair}, Last: {last}"); 
     }, 
     ex => { 
      Console.WriteLine($"Oh no! {ex}"); 
     }); 
    }; 

    WampChannelReconnector reconnector = 
     new WampChannelReconnector(channel, connect); 

    reconnector.Start(); 

    Console.WriteLine("Press a key to exit"); 
    Console.ReadKey(); 
} 

這是基於this代碼示例。

擺脫Console.WriteLine它與你的代碼干擾。
