Syntax

public sealed class ScraperResult

Remarks

A scraper method that is declared to return an instance of ScraperResult must never return null. For convenience there are two static result instances that indicate Subsembly.Scraper.ScraperResult.Success or Subsembly.Scraper.ScraperResult.Failure. The latter should rarely be used, if at all. An implementation shall always try to return as much error information as possible. As an additional convenience, the constructor ScraperResult(Exception) can be used to easily convert runtime exceptions to a ScraperResult.

Constructors

System.String	sChallengeMimeType

ScraperResult(ScraperResultCode, String, String)

Declaration

public ScraperResult(ScraperResultCode nCode, string sDisplayText = null, string sDiagnosticTrace = null)

Parameters

Type	Name	Description
ScraperResultCode	nCode	Value for Code.
System.String	sDisplayText	Value for DisplayText.
System.String	sDiagnosticTrace	Value for DiagnosticTrace.

ScraperResult(Exception)

Declaration

public ScraperResult(Exception x)

Parameters

Type	Name	Description
System.Exception	x

Fields

MIMETYPE_HHD13

Special value for ChallengeMimeType to indicate a ChipTAN challenge according to HHD 1.3.

Declaration

public const string MIMETYPE_HHD13 = "application/x-hhd13"

Field Value

Type	Description
System.String

MIMETYPE_HHD14

Special value for ChallengeMimeType to indicate a ChipTAN challenge according to HHD 1.4.

Declaration

public const string MIMETYPE_HHD14 = "application/x-hhd14"

Field Value

Type	Description
System.String

Properties

ChallengeAlternateLink

Declaration

public Uri ChallengeAlternateLink { get; }

Property Value

Type	Description
System.Uri

ChallengeData

If the Code is ChallengeResponseNeeded, then this property provides the optional challenge data from the service.

Declaration

public byte[] ChallengeData { get; }

Property Value

Type	Description
System.Byte[]

Remarks

The interpretation of this data blob depends on the actual ChallengeType that is in effect. For some challenge/response methods this might even be null.

ChallengeMimeType

If the Code is ChallengeResponseNeeded, then this property indicates the MIME-type of the challenge data, if any, this might even be 'null'.

Declaration

public string ChallengeMimeType { get; }

Property Value

Type	Description
System.String

ChallengeResponseLabel

The text input label that shall be used to collect the ChallengeResponse from the user.

Declaration

public string ChallengeResponseLabel { get; }

Property Value

Type	Description
System.String

Remarks

If this is not set by a particular implementation, then the default string "TAN" is returned, so the returned string is never null.

ChallengeType

If the Code is ChallengeResponseNeeded, then this property indicates the type of challenge/response mechanism that is used.

Declaration

public ScraperResultChallengeType ChallengeType { get; }

Property Value

Type	Description
ScraperResultChallengeType

Code

Success or failure code.

Declaration

public ScraperResultCode Code { get; }

Property Value

Type	Description
ScraperResultCode

DiagnosticTrace
