B2Csignin自定义策略中添加用户输入

在B2C signin自定义策略中，可以通过添加TechnicalProfile的方式来添加额外的用户输入。以下示例添加了一个“PhoneVerification”技术配置文件，以在登录页上要求用户输入其手机号码进行验证。

<TechnicalProfile Id="PhoneVerification">
  <DisplayName>Phone Verification</DisplayName>
  <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.PhoneFactorProvider" />
  <Metadata>
    <Item Key="ContentDefinitionReferenceId">api.phonefactor</Item>
    <Item Key="ManualPhoneNumberEntryAllowed">true</Item>
  </Metadata>
  <CryptographicKeys>
    <Key Id="PhoneFactorKey" StorageReferenceId="TokenSigningKeyContainer" />
  </CryptographicKeys>
  <InputClaimsTransformations>
    <InputClaimsTransformation ReferenceId="CreateUserIdForPhoneFactor" />
  </InputClaimsTransformations>
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="phoneNumber" />
  </InputClaims>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="Verified.strongAuthenticationPhoneNumber" PartnerClaimType="VerifiedPhoneNumber" />
  </OutputClaims>
  <UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
</TechnicalProfile>

然后，在用户流程中添加此技术配置文件，以在登录页面上添加验证手机号的选项。示例代码如下：

<UserJourney Id="SignIn">
  <OrchestrationSteps>
    <OrchestrationStep Order="1" Type="CombinedSignInAndSignUp" ContentDefinitionReferenceId="api.signuporsignin">
      <ClaimsProviderSelections>
        <ClaimsProviderSelection ValidationClaimsExchangeId="LocalAccountSigninEmailExchange" />
      </ClaimsProviderSelections>
      <ClaimsExchange>
        <ClaimsExchangeId>LocalAccountSigninEmailExchange</ClaimsExchangeId>
        <AuthenticationTechnicalProfiles>
          <AuthenticationTechnicalProfile TechnicalProfileReferenceId="LocalAccountSignInWithEmail" />
          <AuthenticationTechnicalProfile TechnicalProfileReferenceId="PhoneVerification" />
        </AuthenticationTechnicalProfiles>
      </ClaimsExchange>
    </OrchestrationStep>
  </OrchestrationSteps>
</UserJourney>
