Question

我正在将ServerEventsClient用于客户端的服务器端事件。目前，如果我关闭服务器，则客户端在以后再次可用时不会自动重新连接。

如何让它自动尝试连接？

我们的测试确实显示ServerEventsClient在重新启动App Server时会自动重新连接，这是我们使用的简单测试：

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();

显示ServerEventClient在连接的AppServer重新启动时自动重新连接的日志：
