Integer claims transformations

  • Άρθρο

This article provides examples for using the integer claims transformations of the Identity Experience Framework schema in Azure Active Directory B2C (Azure AD B2C). For more information, see ClaimsTransformations.

AdjustNumber

Increases or decreases a numeric claim and return a new claim. Check out the Live demo of this claims transformation.

Element TransformationClaimType Data Type Notes
InputClaim inputClaim int The claim type, which contains the number to increase or decrease. If the inputClaim claim value is null, the default of 0 is used.
InputParameter Operator string Possible values: INCREMENT (default), or DECREMENT.
OutputClaim outputClaim int The claim type that is produced after this claims transformation has been invoked.

Example of AdjustNumber

Use this claim transformation to increase or decrease a numeric claim value. The following claim transformation increases a numeric claim value.

<ClaimsTransformation Id="UpdateSteps" TransformationMethod="AdjustNumber">
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="steps" TransformationClaimType="inputClaim" />
  </InputClaims>
  <InputParameters>
    <InputParameter Id="Operator" DataType="string" Value="INCREMENT" />
  </InputParameters>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="steps" TransformationClaimType="outputClaim" />
  </OutputClaims>
</ClaimsTransformation>
  • Input claims:
    • inputClaim: 1
  • Input parameters:
    • Operator: INCREMENT
  • Output claims:
    • outputClaim: 2

Example of AdjustNumber with null value

If the input claim is null, the output claim will be one.

  • Input claims:
    • inputClaim: NULL
  • Input parameters:
    • Operator: INCREMENT
  • Output claims:
    • outputClaim: 1

AssertNumber

Determines whether a numeric claim is greater, lesser, equal, or not equal to a number. Check out the Live demo of this claims transformation.

Element TransformationClaimType Data Type Notes
InputClaim inputClaim int The first numeric claim to compare whether it's greater, lesser, equal, or not equal than the second number. Null value throws an exception.
InputParameter CompareToValue int The second number to compare whether it's greater, lesser, equal, or not equal than the first number.
InputParameter Operator string Possible values: LessThan, GreaterThan, GreaterThanOrEqual, LessThanOrEqual, Equal, NotEqual.
InputParameter throwError boolean Specifies whether this assertion should throw an error if the comparison result is true. Possible values: true (default), or false.
 
When set to true (Assertion mode), and the comparison result is true, an exception will be thrown. When set to false (Evaluation mode), the result is a new boolean claim type with a value of true, or false.
OutputClaim outputClaim boolean If ThrowError is set to false, this output claim contains true, or false according to the comparison result.

Assertion mode

When throwError input parameter is true (default), the AssertNumber claims transformation is always executed from a validation technical profile that is called by a self-asserted technical profile.

The AssertNumberError self-asserted technical profile metadata controls the error message that the technical profile presents to the user. The error messages can be localized.

<TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">
  <Metadata>
    <Item Key="AssertNumberError">You've reached the maximum logon attempts</Item>
  </Metadata>
  ...
</TechnicalProfile>

For more information how to call the claims transformation in an assertion mode, see AssertStringClaimsAreEqual, AssertBooleanClaimIsEqualToValue, and AssertDateTimeIsGreaterThan claims transformations.

Example of AssertNumber

The following example asserts the number of attempts is over five. The claims transformation throws an error according to the comparison result.

<ClaimsTransformation Id="isOverLimit" TransformationMethod="AssertNumber">
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="attempts" TransformationClaimType="inputClaim" />
  </InputClaims>
  <InputParameters>
    <InputParameter Id="Operator" DataType="string" Value="GreaterThan" />
    <InputParameter Id="CompareToValue" DataType="int" Value="5" />
    <InputParameter Id="throwError" DataType="boolean" Value="true" />
  </InputParameters>
</ClaimsTransformation>
  • Input claims:
    • inputClaim: 10
  • Input parameters:
    • Operator: GreaterThan
    • CompareToValue: 5
    • throwError: true
  • Result: Error thrown

Example of AssertNumber evaluation mode

The following example evaluates whether the number of attempts is over five. The output claim contains a boolean value according to the comparison result. The claims transformation won't throw an error.

<ClaimsTransformation Id="isOverLimit" TransformationMethod="AssertNumber">
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="attempts" TransformationClaimType="inputClaim" />
  </InputClaims>
  <InputParameters>
    <InputParameter Id="Operator" DataType="string" Value="GreaterThan" />
    <InputParameter Id="CompareToValue" DataType="int" Value="5" />
    <InputParameter Id="throwError" DataType="boolean" Value="false" />
  </InputParameters>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="attemptsCountExceeded" TransformationClaimType="outputClaim" />
  </OutputClaims>
</ClaimsTransformation>
  • Input claims:
    • inputClaim: 10
  • Input parameters:
    • Operator: GreaterThan
    • CompareToValue: 5
    • throwError: false
  • Output claims:
    • outputClaim: true

ConvertNumberToStringClaim

Converts a long data type into a string data type. Check out the Live demo of this claims transformation.

Element TransformationClaimType Data Type Notes
InputClaim inputClaim long The claim type to convert to a string.
OutputClaim outputClaim string The claim type that is produced after this claims transformation has been invoked.

Example of ConvertNumberToStringClaim

In this example, the numericUserId claim with a value type of long is converted to a UserId claim with a value type of string.

<ClaimsTransformation Id="CreateUserId" TransformationMethod="ConvertNumberToStringClaim">
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="numericUserId" TransformationClaimType="inputClaim" />
  </InputClaims>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="UserId" TransformationClaimType="outputClaim" />
  </OutputClaims>
</ClaimsTransformation>
  • Input claims:
    • inputClaim: 12334 (long)
  • Output claims:
    • outputClaim: "12334" (string)
