SiteIdentityPermission-Klasse
Definiert die Identitätsberechtigung für die Website, aus der der Code stammt. Diese Klasse kann nicht vererbt werden.
Namespace: System.Security.Permissions
Assembly: mscorlib (in mscorlib.dll)

public final class SiteIdentityPermission extends CodeAccessPermission
Hinweise
Durch die Verwendung dieser Klasse kann sichergestellt werden, dass der Aufruf von einer bestimmten Website aus erfolgte. Die Site-Identität wird nur bei Code von URLs mit den Protokollen HTTP, HTTPS und FTP definiert. Eine Site ist die Zeichenfolge zwischen dem "//", das nach dem Protokoll eines URL steht, und dem folgenden "/" (sofern vorhanden), z. B. www.fourthcoffee.com im URL https://www.fourthcoffee.com/process/grind.htm. Anschlussnummern werden hierdurch ausgeschlossen. Wenn ein URL https://www.fourthcoffee.com:8000/ lautet, ist die entsprechende Site www.fourthcoffee.com, nicht www.fourthcoffee.com:8000.
Die Site kann mit dem genauen Namen oder mithilfe eines vorangestellten Platzhalters ("*") vor dem Trennpunkt angegeben werden. Die Zeichenfolge für den Sitenamen *.fourthcoffee.com stimmt sowohl mit fourthcoffee.com als auch mit www.fourthcoffee.com überein. Ohne Platzhalterzeichen muss der angegebene Sitename genau dem tatsächlichen Namen entsprechen. Die Zeichenfolge * für den Sitenamen entspricht allen Sites, nicht jedoch Code ohne Sitebeweis.
Warnung
Die SiteIdentityPermission-Klasse gewährt die Berechtigung für alle Pfade zur Site, einschließlich URL und IP-Adresse. Um für den Zugriff auf eine Site auf Deny festzulegen, müssen Sie die Deny-Methode für alle möglichen Pfade der Site festlegen. Wenn z. B. www.fourthcoffee.com die IP-Adresse 192.168.238.241 hat und Sie den Zugriff auf www.fourthcoffee.com mit Deny verweigern möchten, müssen Sie die Deny-Methode sowohl für www.fourthcoffee.com als auch für 192.168.238.241 und alle anderen Pfade festlegen, über die auf die Site zugegriffen werden kann. Ein einfacheres Verfahren für den Umgang mit mehreren Pfaden besteht in der Kombination aus PermitOnly-Methode und Deny-Methode. Weitere Informationen über dieses Thema und die Verwendung der PermitOnly-Methode mit der Deny-Methode finden Sie unter Canonicalization Problems Using Deny im Thema Verwenden der Deny-Methode.
Hinweis
In .NET Framework, Versionen 1.0 und 1.1, können Identitätsberechtigungen nicht den Berechtigungszustandswert Unrestricted haben. In .NET Framework, Version 2.0, können Identitätsberechtigungen jeden Berechtigungszustandswert haben. Das heißt, dass Identitätsberechtigungen in Version 2.0 über das gleiche Verhalten verfügen wie Berechtigungen, die die IUnrestrictedPermission-Schnittstelle implementieren. Informationen über die Ausführung von Version 2.0-Anwendungen mit der Version 1.1-Zertifizierungsstellenrichtlinie finden Sie unter <legacyV1CASPolicy>-Element.
