UserNameSecurityTokenAuthenticator.ValidateUserNamePasswordCore 方法

定义

命名空间:
System.IdentityModel.Selectors
程序集:
System.IdentityModel.dll

在派生类中重写时，对指定的用户名和密码进行身份验证，并返回安全令牌的授权策略 UserNameSecurityToken 集。

protected:
 abstract System::Collections::ObjectModel::ReadOnlyCollection<System::IdentityModel::Policy::IAuthorizationPolicy ^> ^ ValidateUserNamePasswordCore(System::String ^ userName, System::String ^ password);
protected abstract System.Collections.ObjectModel.ReadOnlyCollection<System.IdentityModel.Policy.IAuthorizationPolicy> ValidateUserNamePasswordCore(string userName, string password);
abstract member ValidateUserNamePasswordCore : string * string -> System.Collections.ObjectModel.ReadOnlyCollection<System.IdentityModel.Policy.IAuthorizationPolicy>
Protected MustOverride Function ValidateUserNamePasswordCore (userName As String, password As String) As ReadOnlyCollection(Of IAuthorizationPolicy)

参数

userName
String

与安全令牌关联的用户名。

password
String

与安全令牌关联的密码。

返回

ReadOnlyCollection<IAuthorizationPolicy>

一种 ReadOnlyCollection<T> 类型 IAuthorizationPolicy ，其中包含此应用程序的授权策略集。

示例

protected override ReadOnlyCollection<IAuthorizationPolicy> ValidateUserNamePasswordCore(string userName, string password)
{
    if (!ValidateUserNameFormat(userName))
        throw new SecurityTokenValidationException("Incorrect UserName format");

    ClaimSet claimSet = new DefaultClaimSet(ClaimSet.System, new Claim(ClaimTypes.Name, userName, Rights.PossessProperty));
    List<IIdentity> identities = new List<IIdentity>(1);
    identities.Add(new GenericIdentity(userName));
    List<IAuthorizationPolicy> policies = new List<IAuthorizationPolicy>(1);
    policies.Add(new UnconditionalPolicy(ClaimSet.System, claimSet, DateTime.MaxValue.ToUniversalTime(), identities));
    return policies.AsReadOnly();
}

    Protected Overrides Function ValidateUserNamePasswordCore(ByVal userName As String, ByVal password As String) As ReadOnlyCollection(Of IAuthorizationPolicy)

        If Not ValidateUserNameFormat(userName) Then
            Throw New SecurityTokenValidationException("Incorrect UserName format")
        End If
        Dim setOfClaims As New DefaultClaimSet(ClaimSet.System, New Claim(ClaimTypes.Name, userName, Rights.PossessProperty))
        Dim identities As New List(Of IIdentity)(1)

        identities.Add(New GenericIdentity(userName))
        Dim policies As New List(Of IAuthorizationPolicy)(1)
        policies.Add(New UnconditionalPolicy(ClaimSet.System, setOfClaims, DateTime.MaxValue.ToUniversalTime(), identities))
        Return policies.AsReadOnly()

    End Function 'New
End Class
