WCF用户名验证:我可以在自定义ServiceAuthorizationManager中获取用户名吗?

authorization wcf .net c#

ServiceAuthorizationManager . 自定义身份验证管理器已设置为处理Windows和窗体身份验证。

但是,如果我连接的客户端设置为 UserName auth,我似乎在任何地方都找不到用户名。

客户端代码如下所示:

this.ClientCredentials.UserName.UserName = "user";
this.ClientCredentials.UserName.Password = "pass";
this.Open();
this.MyMethod(); // my actual contract method
this.Close();

public sealed class AppAuthorizationManager : ServiceAuthorizationManager
{
    public override bool CheckAccess(OperationContext operationContext, ref Message message)
    {
        // would like to check user/pwd here...
    }
}

这可能吗?

这个 Thread.CurrentPrincipal 没有设定,,
operationContext.ServiceSecurityContext.PrimaryIdentity
operationContext.ServiceSecurityContext.AuthorizationContext.ClaimSets 是空的。

用户/pwd是否应该在任何地方可用?还是我必须添加自定义 UsernamePasswordValidator 也

更新: 所以我添加了一个自定义项 UserNamePasswordValidator 和 IAuthorizationPolicy . 我更新的WCF配置如下所示:

<behavior name="Server2ServerBehavior">
  <serviceMetadata httpGetEnabled="true" />
  <serviceDebug includeExceptionDetailInFaults="true" />
  <serviceAuthorization principalPermissionMode="Custom" serviceAuthorizationManagerType="MyApp.AuthManager, MyApp">
    <authorizationPolicies>
      <add policyType="MyApp.TokenAuthorizationPolicy, MyApp" />
    </authorizationPolicies>
  </serviceAuthorization>
  <serviceCredentials>
    <userNameAuthentication customUserNamePasswordValidatorType="MyApp.PFUserNameValidator, MyApp" />
  </serviceCredentials>
</behavior>

如果我在所有3个类中设置了断点,WCF将抛出异常:

LogonUser failed for the 'username' user. Ensure that the user has a valid Windows account.
   at System.IdentityModel.Selectors.WindowsUserNameSecurityTokenAuthenticator.ValidateUserNamePasswordCore(String userName, String password)

这通常是在 UsernamePasswordValidator IAuthorizationPolicy 的 Evaluate

bool IAuthorizationPolicy.Evaluate(
    EvaluationContext evaluationContext, ref object state)
{           
    IList<IIdentity> idents;
    object identsObject;
    if (evaluationContext.Properties.TryGetValue(
        "Identities", out identsObject) && (idents =
        identsObject as IList<IIdentity>) != null)
    {
        foreach (IIdentity ident in idents)
        {
            if (ident.IsAuthenticated &&
                ident.AuthenticationType == TrustedAuthType)
            {                           
                evaluationContext.Properties["Principal"]
                    = //TODO our principal
                return true;
            }
        }
    }
    if (!evaluationContext.Properties.ContainsKey("Principal"))
    {
        evaluationContext.Properties["Principal"] = //TODO anon
    }                
    return false;
}

(在哪里 TrustedAuthType 是我们的密码验证程序的名称)
