UserNamePasswordServiceCredential.CacheLogonTokens 属性

定义

命名空间:

System.ServiceModel.Security

程序集:

System.ServiceModel.dll

获取或设置一个值，该值指示是否缓存登录令牌。

public:
 property bool CacheLogonTokens { bool get(); void set(bool value); };

public bool CacheLogonTokens { get; set; }

member this.CacheLogonTokens : bool with get, set

Public Property CacheLogonTokens As Boolean

属性值

Boolean

如果缓存登录令牌，则为 true；否则为 false。 默认值为 false。

示例

下面的示例获取该属性的值。

// Create a service host.
Uri httpUri = new Uri("http://localhost/Calculator");
ServiceHost sh = new ServiceHost(typeof(Calculator), httpUri);

// Create a binding that uses a username/password credential.
WSHttpBinding b = new WSHttpBinding(SecurityMode.Message);
b.Security.Message.ClientCredentialType = MessageCredentialType.UserName;

// Add an endpoint.
sh.AddServiceEndpoint(typeof(ICalculator), b, "UserNamePasswordCalculator");

// Get a reference to the UserNamePasswordServiceCredential object.
UserNamePasswordServiceCredential unpCredential =
    sh.Credentials.UserNameAuthentication;
// Print out values.
Console.WriteLine("IncludeWindowsGroup: {0}",
    unpCredential.IncludeWindowsGroups);
Console.WriteLine("UserNamePasswordValidationMode: {0}",
    unpCredential.UserNamePasswordValidationMode);
Console.WriteLine("CachedLogonTokenLifetime.Minutes: {0}",
    unpCredential.CachedLogonTokenLifetime.Minutes );
Console.WriteLine("CacheLogonTokens: {0}",
    unpCredential.CacheLogonTokens );
Console.WriteLine("MaxCachedLogonTokens: {0}",
    unpCredential.MaxCachedLogonTokens );

Console.ReadLine();

' Create a service host.
Dim httpUri As New Uri("http://localhost/Calculator")
Dim sh As New ServiceHost(GetType(Calculator), httpUri)

' Create a binding that uses a username/password credential.
Dim b As New WSHttpBinding(SecurityMode.Message)
b.Security.Message.ClientCredentialType = MessageCredentialType.UserName

' Add an endpoint.
sh.AddServiceEndpoint(GetType(ICalculator), b, "UserNamePasswordCalculator")

' Get a reference to the UserNamePasswordServiceCredential object.
Dim unpCredential As UserNamePasswordServiceCredential = sh.Credentials.UserNameAuthentication
' Print out values.
Console.WriteLine("IncludeWindowsGroup: {0}", unpCredential.IncludeWindowsGroups)
Console.WriteLine("UserNamePasswordValidationMode: {0}", unpCredential.UserNamePasswordValidationMode)
Console.WriteLine("CachedLogonTokenLifetime.Minutes: {0}", unpCredential.CachedLogonTokenLifetime.Minutes)
Console.WriteLine("CacheLogonTokens: {0}", unpCredential.CacheLogonTokens)
Console.WriteLine("MaxCachedLogonTokens: {0}", unpCredential.MaxCachedLogonTokens)

Console.ReadLine()

注解

默认情况下，如果用户名映射到Windows帐户，WCF 安全性要求Windows安全子系统为每个传入用户名/密码安全令牌创建登录令牌。 通过设置 UserNamePasswordValidationMode 属性，可以更改此行为。

对于 Windows 模式，服务使用 Win32 的 LogonUser 函数进行用户名/密码身份验证。 如果 CacheLogonTokens 设置为 true，则将缓存生成的 Windows 令牌，并且对相同的用户名/密码对重用该令牌。 缓存对 CachedLogonTokenLifetime 有效。 缓存的最大数目限制为 MaxCachedLogonTokens。
