WebSync发布ClientId变为零

Question

当我在Client.clientId方法中传递Websync发布时，当从客户端捕获OnReceive事件时，clientId有时会变成零。

我可以知道为什么有时clientId值通过通道成功地发送，但最常见的情况是，clientId值在某种程度上变成零，就像00000000-0000-0000-000000000000一样。

var client = new fm.websync.client('http://localhost:12345/websync');

client.connect
({
    onSuccess: function (e) {
        $('#connectionStat').val('Successfully connected');
    },
    onFailure: function (e) {
        $('#connectionStat').val('Failed to be connected');
    },
    onStreamFailure: function (e) {
        $('#connectionStat').val('Failed to be connected on stream');
    }
});

client.subscribe({
    channel: '/testService/clientId',
    onSuccess: function (e) {

    },
    onFailure: function (e) {

    },
    onReceive: function (e) {
        alert(e.getData());
    }
});

Client client = new Client("http://localhost:12345/websync");
client.Connect(new ConnectArgs
{
       OnSuccess = (e) =>
       {
          Debug.WriteLine("Successfully connected [OnSuccess]");
       },
       OnFailure = (e) =>
       {
           Debug.WriteLine("Failed in connected [OnFailure]");
       },
       OnComplete = (e) =>
       {
           Debug.WriteLine("Successfully connected [OnComplete]");
        },
        OnStreamFailure = (e) =>
        {
           Debug.WriteLine("Failed connected [OnStreamFailure]");
        }
});   

client.Publish(new PublishArgs("/testService/clientId", Json.Serialize(client.ClientId))
{
       OnSuccess = (e) =>
       {
           Debug.WriteLine("Successfully published client id [OnSuccess] = " + client.ClientId.ToString());
       },
       OnComplete = (e) =>
       {
           Debug.WriteLine("Successfully published [OnComplete]");
       },
       OnFailure = (e) =>
       {
           Debug.WriteLine("Failed to publish [OnFailure]");
       },
});

等待Publish，直到Connect成功完成。客户端的ID由服务器生成，当调用Publish时，Connect操作可能尚未完成。

最简单的方法是将Publish调用移动到Connect的OnSuccess回调中。
