为我已经工作的 REST 服务启用令牌

Question

我已经创建了 REST 服务，它运行良好。当我调用方法时，我会向我发送 Json 响应。

现在我想启用令牌。我编写代码来生成令牌并运行它。它给了我以下错误：

合同需要会话，但绑定 'WebHttpBinding' 不支持它或未正确配置以支持它。

请告诉我解决此问题需要进行哪些更改。

网络配置

服务Class接口

[ServiceContract(SessionMode = SessionMode.Required)]
//[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebInvoke(
        Method = "GET",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "GetStudent")]
    string GetStudent();

    [OperationContract]
    [WebInvoke(
        Method = "POST",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "AuthenticateUser")]
    string AuthenticateUser(string user, string pwd);
}

服务实施Class

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
//[ServiceBehavior]
public class Service : IService
{
    string UserToken = string.Empty;
    public bool IsValidateUser()
    {
        //Getting the user token from client request
        if (OperationContext.Current.IncomingMessageHeaders.FindHeader("TokenHeader", "TokenNameSpace") == -1)
        {
            return false;
        }

        string userIdentityToken = Convert.ToString(OperationContext.Current.IncomingMessageHeaders.GetHeader<string>("TokenHeader", "TokenNameSpace"));

        //Authenticating user with token, if it is validated then returning employee data
        if (userIdentityToken == UserToken)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

    public string GetStudent()
    {

       JavaScriptSerializer js = new JavaScriptSerializer();
       return js.Serialize(Student.GetStudent());

    }

    public string AuthenticateUser(string user, string pwd)
    {
        if (!(string.IsNullOrEmpty(user)) && !(string.IsNullOrEmpty(pwd)))
        {
            UserToken = OperationContext.Current.SessionId;
        }
        return UserToken;
    }
}

Answer 1

我找到了另一种解决方案，即我创建了一个自定义（某些值的组合）加密令牌。它工作正常。我必须使用数据库方法来使用它。
