예제

다음 예제에서는 사용자 지정된 권한 집합을 XmlSecureResolver 사용하여 개체를 생성합니다.

public static Object GetFile (String fileURL, XmlResolver resolver) {

  // Generate the default PermissionSet using the file URL.
  Evidence evidence = XmlSecureResolver.CreateEvidenceForUrl(fileURL);
  PermissionSet myPermissions = SecurityManager.ResolvePolicy(evidence);

  // Modify the PermissionSet to only allow access to http://www.contoso.com.
  // Create a WebPermission which only allows access to http://www.contoso.com.
  WebPermission myWebPermission = new WebPermission(NetworkAccess.Connect, "http://www.contoso.com");
  // Replace the existing WebPermission in myPermissions with the updated WebPermission.
  myPermissions.SetPermission(myWebPermission);

  // Use the modified PermissionSet to construct the XmlSecureResolver.
  XmlSecureResolver sResolver = new XmlSecureResolver(resolver, myPermissions);

  // Get the object.
  Uri fullUri = sResolver.ResolveUri(null, fileURL);
  return sResolver.GetEntity(fullUri, null, null);
}

public shared function GetFile (fileURL as String , resolver as XmlResolver) as Object
 
  '  Generate the default PermissionSet using the file URL.
  Dim evidence as Evidence = XmlSecureResolver.CreateEvidenceForUrl(fileURL)
  Dim myPermissions as PermissionSet = SecurityManager.ResolvePolicy(evidence)

설명

다음은 각 시나리오에 대해 제공할 수 있는 몇 가지 시나리오 및 증거 유형입니다.

• 완전히 신뢰할 수 있는 환경에서 작업하는 경우 어셈블리를 사용하여 증거를 만듭니다.

  Evidence myEvidence = this.GetType().Assembly.Evidence;
  XmlSecureResolver myResolver;
  myResolver = new XmlSecureResolver(new XmlUrlResolver(), myEvidence);
  

  Dim myEvidence As Evidence = Me.GetType().Assembly.Evidence
  Dim myResolver As XmlSecureResolver
  myResolver = New XmlSecureResolver(New XmlUrlResolver(), myEvidence)
  

• 반 신뢰할 수 있는 환경에서 작업하는 경우 외부 원본에서 오는 코드 또는 데이터가 있고 외부 원본의 출처를 알고 있으며 확인 가능한 URI가 있는 경우 URI를 사용하여 증거를 만듭니다.

  
  Evidence myEvidence = XmlSecureResolver.CreateEvidenceForUrl(sourceURI);
  XmlSecureResolver myResolver = new XmlSecureResolver(new XmlUrlResolver(), myEvidence);
  

  Dim myEvidence As Evidence = XmlSecureResolver.CreateEvidenceForUrl(sourceURI)
  Dim myResolver As New XmlSecureResolver(New XmlUrlResolver(), myEvidence)
  

• 반 신뢰할 수 있는 환경에서 작업 중이고 외부 원본에서 오는 코드 또는 데이터가 있지만 외부 원본의 출처를 모르는 경우 다음 중 하나를 수행합니다.

  evidence 매개 변수를 null로 설정합니다. 이렇게 하면 리소스에 액세스할 수 없습니다.

  -또는-

  애플리케이션에 리소스에 대한 액세스 권한이 필요한 경우 호출자에게 증거를 요청합니다.

예제

이 예제에서는 생성자를 사용하여 XmlSecureResolver(XmlResolver, String) 로컬 인트라넷 사이트에만 액세스할 수 있는 개체를 만듭니 XmlSecureResolver 다.

XmlSecureResolver myResolver = new XmlSecureResolver(new XmlUrlResolver(), "http://myLocalSite/");

Dim myResolver As New XmlSecureResolver(New XmlUrlResolver(), "http://myLocalSite/")
