javascript - WebSync Publish ClientId 变为零

Question

当我在 Websync publish 中传递 Client.clientId 时出现问题方法中，当被 OnReceive 捕获时，clientId 有时会变成全零。来自客户端的事件。

我可以知道为什么有时 clientId 值会通过 channel 成功发送，但大多数情况下 clientId 值会以某种方式变为全零，例如 00000000-0000-0000-0000-000000000000。

下面是我的代码

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]");
       },
});

等待发布，直到连接成功完成。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 调用移至 Connect 的 OnSuccess 回调中。
