構文
'宣言
Public Sub New ( _
token As String, _
finished As Boolean, _
connectionGroupId As String _
)
'使用
Dim token As String
Dim finished As Boolean
Dim connectionGroupId As String
Dim instance As New Authorization(token, finished, connectionGroupId)
public Authorization (
string token,
bool finished,
string connectionGroupId
)
public:

パラメータ
- token
サーバーが受信する暗号化された承認メッセージ。
- finished
承認試行の完了ステータス。承認試行が完了した場合は true。それ以外の場合は false。
- connectionGroupId
この承認方式だけにバインドされるプライベート クライアント サーバー接続を作成するために使用できる一意の識別子。
使用例
指定した承認メッセージ、承認の完了ステータス、および接続グループ識別子を使用して、Authorization クラスの新しいインスタンスを作成するコード例を次に示します。
