仅带有忠诚度编号和电子邮件的Azure AD B2C自定义策略注册

Question

我正在创建一个自定义的仅注册策略，该策略应在url中接收两个属性：

• 通过电子邮件发送地址（可选）
• 会员编号（必填）

如果我的url中有电子邮件地址，我希望将其预先填写在框中（并且是只读的，但是我可以使用html / css来解决这个问题）和会员编号。

我已经创建了自定义策略，但是无法预先填写电子邮件（=用户名）。

我已经创建了一个UserJourney：

<UserJourney Id="SignUp">
      <OrchestrationSteps>

        <OrchestrationStep Order="1" Type="ClaimsProviderSelection" ContentDefinitionReferenceId="api.idpselections.signup">
          <ClaimsProviderSelections>
            <ClaimsProviderSelection TargetClaimsExchangeId="SignUpWithLogonEmailExchange" />
          </ClaimsProviderSelections>
        </OrchestrationStep>

        <OrchestrationStep Order="2" Type="ClaimsExchange">
          <Preconditions>
            <Precondition Type="ClaimsExist" ExecuteActionsIf="true">
              <Value>objectId</Value>
              <Action>SkipThisOrchestrationStep</Action>
            </Precondition>
          </Preconditions>
          <ClaimsExchanges>
            <ClaimsExchange Id="SignUpWithLogonEmailExchange" TechnicalProfileReferenceId="LocalAccountSignUpWithLogonEmail" />
          </ClaimsExchanges>
        </OrchestrationStep>

        <!-- This step reads any user attributes that we may not have received when in the token. -->
        <OrchestrationStep Order="3" Type="ClaimsExchange">
          <ClaimsExchanges>
            <ClaimsExchange Id="AADUserReadWithObjectId" TechnicalProfileReferenceId="AAD-UserReadUsingObjectId" />
          </ClaimsExchanges>
        </OrchestrationStep>
 
        <OrchestrationStep Order="4" Type="SendClaims" CpimIssuerTechnicalProfileReferenceId="JwtIssuer" />
      </OrchestrationSteps>
    </UserJourney>

以及注册策略：

<BasePolicy>
    <TenantId>tenant.onmicrosoft.com</TenantId>
    <PolicyId>B2C_1A_TrustFrameworkExtensions</PolicyId>
  </BasePolicy>
  
  <ClaimsProviders>
    <ClaimsProvider>
      <DisplayName>Local Account</DisplayName>
      <TechnicalProfiles>
        <TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">
          <InputClaims>
            <!-- Add the login hint value to the sign-in names claim type -->
            <InputClaim ClaimTypeReferenceId="signInName" DefaultValue="{OIDC:LoginHint}" />
          </InputClaims>
        </TechnicalProfile>
      </TechnicalProfiles>
    </ClaimsProvider>
  </ClaimsProviders>

  <RelyingParty>
    <DefaultUserJourney ReferenceId="SignUp" />
    
    <TechnicalProfile Id="PolicyProfile">
      <DisplayName>PolicyProfile</DisplayName>
      <Protocol Name="OpenIdConnect" />
      
      <OutputClaims>
        <OutputClaim ClaimTypeReferenceId="displayName" />
        <OutputClaim ClaimTypeReferenceId="givenName" />
        <OutputClaim ClaimTypeReferenceId="surname" />
        <OutputClaim ClaimTypeReferenceId="email" />
        <OutputClaim ClaimTypeReferenceId="objectId" PartnerClaimType="sub"/>
        <OutputClaim ClaimTypeReferenceId="tenantId" AlwaysUseDefaultValue="true" DefaultValue="{Policy:TenantObjectId}" />
      </OutputClaims>
      <SubjectNamingInfo ClaimType="sub" />
    </TechnicalProfile>
  </RelyingParty>
</TrustFrameworkPolicy>
