WebSocketSession

A WebSocket session is a persistent connection between a GS2 server and a client for real-time bidirectional communication. The client registers a user ID as an identifier to the server.

	Type	Require	Limitation	Description
connectionId	string	✓	~ 128 chars	connection ID
namespaceName	string	✓	~ 128 chars	Namespace name
userId	string	✓	~ 128 chars	User Id

Methods

setUserId

Set user ID to receive push notifications from the server

Request

	Type	Require	Default	Limitation	Description
namespaceName	string	✓		~ 128 chars	Namespace name
accessToken	string	✓		~ 128 chars	User Id
allowConcurrentAccess	bool	✓	true		Allow connections from different clients at the same time

Result

	Type	Description
item	EzWebSocketSession	Updated Websocket session

Implementation Example

    var domain = gs2.Gateway.Namespace(
        namespaceName: "namespace-0001"
    ).Me(
        gameSession: GameSession
    ).WebSocketSession(
    );
    var result = await domain.SetUserIdAsync(
        allowConcurrentAccess: null
    );
    var item = await result.ModelAsync();

    var domain = gs2.Gateway.Namespace(
        namespaceName: "namespace-0001"
    ).Me(
        gameSession: GameSession
    ).WebSocketSession(
    );
    var future = domain.SetUserIdFuture(
        allowConcurrentAccess: null
    );
    yield return future;
    if (future.Error != null)
    {
        onError.Invoke(future.Error, null);
        yield break;
    }
    var future2 = future.Result.Model();
    yield return future2;
    if (future2.Error != null)
    {
        onError.Invoke(future2.Error, null);
        yield break;
    }
    var result = future2.Result;

    const auto Domain = Gs2->Gateway->Namespace(
        "namespace-0001" // namespaceName
    )->Me(
        GameSession
    )->WebSocketSession(
    );
    const auto Future = Domain->SetUserId(
        // allowConcurrentAccess
    );
    Future->StartSynchronousTask();
    if (Future->GetTask().IsError())
    {
        return false;
    }

    // obtain changed values / result values
    const auto Future2 = Future->GetTask().Result()->Model();
    Future2->StartSynchronousTask();
    if (Future2->GetTask().IsError())
    {
        return Future2->GetTask().Error();
