[英]Programmatically specify custom authorization for WCF (NetTcpBinding)
I want to do the same thing as in this link: 我想做与此链接相同的事情:
http://www.codeproject.com/KB/WCF/Custom_Authorization_WCF.aspx http://www.codeproject.com/KB/WCF/Custom_Authorization_WCF.aspx
But without using configuration files. 但是不使用配置文件。 Can anyone show me how?
谁能告诉我怎么样?
Edit: I want to implement both AuthorizationPolicy and the CustomValidator. 编辑:我想实现AuthorizationPolicy和CustomValidator。
Are you referring about how to add the AuthorizationPolicy through code? 您是指如何通过代码添加AuthorizationPolicy? Untested, but I believe something like this should work:
未经测试,但我相信这样的事情应该有效:
ServiceHost host = ...;
var col = new ReadOnlyCollection<IAuthorizationPolicy>(new IAuthorizationPolicy[] { new MyPolicy() });
ServiceAuthorizationBehavior sa = host.Description.Behaviors.Find<ServiceAuthorizationBehavior>();
if ( sa == null ) {
sa = new ServiceAuthorizationBehavior();
host.Description.Behaviors.Add(sa);
}
sa.ExternalAuthorizationPolicies = col;
If you refer to the this topic (WCF Security: Getting the password of the user) by Rory Primrose , he achieves similar to what you're enquiring about with providing a custom validator, the important extension method being CreateSecurityTokenManager
: 如果你参考Rory Primrose的这个主题(WCF安全:获取用户的密码) ,他会提供类似于你提供自定义验证器的信息,重要的扩展方法是
CreateSecurityTokenManager
:
public class PasswordServiceCredentials : ServiceCredentials
{
public PasswordServiceCredentials()
{
}
private PasswordServiceCredentials(PasswordServiceCredentials clone)
: base(clone)
{
}
protected override ServiceCredentials CloneCore()
{
return new PasswordServiceCredentials(this);
}
public override SecurityTokenManager CreateSecurityTokenManager()
{
// Check if the current validation mode is for custom username password validation
if (UserNameAuthentication.UserNamePasswordValidationMode == UserNamePasswordValidationMode.Custom)
{
return new PasswordSecurityTokenManager(this);
}
Trace.TraceWarning(Resources.CustomUserNamePasswordValidationNotEnabled);
return base.CreateSecurityTokenManager();
}
}
To use this custom service credential, you will need to specify the type attribute on the <ServiceCredentials>
's ConfigurationElement
in your configuration, like: 要使用此自定义服务凭据,您需要在
ConfigurationElement
中的<ServiceCredentials>
的ConfigurationElement
上指定type属性,例如:
<serviceCredentials type="your.assembly.namespace.PasswordServiceCredentials,
your.assembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" >
</serviceCredentials>
Likewise, you could set this type
attribute programatically, but I'm not familiar with how. 同样,您可以以编程方式设置此
type
属性,但我不熟悉如何。
