ServiceStack ServerEventsClient自動重新連接

Question

我正在使用ServerEventsClient服務器端事件給客戶端。目前，如果我關閉了服務器，客戶端在再次可用時不會自動重新連接。

如何讓它自動嘗試連接？

我們的測試也表明，ServerEventsClient做應用服務器重新啓動時自動重新連接，這裏有一個簡單的測試，我們使用：

var client = new ServerEventsClient("http://localhost:11001", "home") 
{ 
    OnConnect = ctx => "OnConnect: {0}".Print(ctx.Channel), 
    OnCommand = msg => "OnCommand: {0}".Print(msg.Data), 
    OnException = ex => "OnException: {0}".Print(ex.Message), 
    OnMessage = msg => "OnMessage: {0}".Print(msg.Data), 
    OnHeartbeat =() => "OnHeartbeat".Print() 
}; 

client.Handlers["chat"] = (source, msg) => 
{ 
    "Received Chat: {0}".Print(msg.Data); 
}; 

await client.Connect(); 

，並顯示了ServerEventClient自動重新連接日誌，當應用服務器它連接以重新啓動：

OnConnect: 
OnCommand: home@cmd.onJoin {"userId":"-2","isAuthenticated":"false","displayName":"user2","channels":"home","profileUrl":"https://raw.githubusercontent.com/ServiceStack/Assets/master/img/apps/no-profile64.png"} 
OnHeartbeat

OnMessage: home@cmd.chat {"id":2,"fromUserId":"-1","fromName":"user1","message":"2","private":false}
