在Azure AD B2C上使用Azure AD登录后获取电子邮件

提问于

Scenario: 我正在使用Angular 5作为前端，使用.NET核2.0作为后端，MSAL.js使用Angular SPA中的Azure AD B2C进行身份验证，然后使用返回的 id_token 作为Bearer Token将请求发送到WebAPI endpoints .

我已成功将多租户Azure AD设置为Azure AD B2C中的提供程序（此处的答案为Multi-tenant Azure AD in Azure AD B2C），但在返回的 id_token 中，没有对电子邮件地址的声明 . 注意：如果我配置单租户Azure AD，我会收到类型为 http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress 的电子邮件地址声明，但无法使用多租户AD .

我相信这个限制是在这里提到的Azure AD v2.0：https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-limitations

Question: 如何在登录后检索用户的电子邮件地址 .

我按照本文https://monteledwards.com/2017/10/18/a-complete-integration-azure-ad-b2c-azure-ad-graph-api-logic-apps/中的指南添加了一个额外的逻辑应用程序来解析来自 id_token 的电子邮件，但我的问题是我没有回复 objectId .

在成功验证后我得到的声明是：

iss - https://login.microsoftonline.com/<My-B2C-Tenant-Id>/v2.0/
exp - ticks
nbf - ticks
aud - My-B2C-App-Id
name - string
http://schemas.microsoft.com/identity/claims/identityprovider - tid
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier - My-B2C-App-Id
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname - string
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname - string
nonce - GUID
http://schemas.microsoft.com/identity/claims/scope - User.Read
azp - GUID
ver - 1.0
iat - ticks

我的多租户Azure AD技术配置文件 - > Azure AD B2C是：

<TechnicalProfile Id="AzureADAccountProfile">

  <Protocol Name="OpenIdConnect"/>
  <OutputTokenFormat>JWT</OutputTokenFormat>

    获取与用户帐户关联的电子邮件地址在使用者/个人帐户和组织/工作帐户之间有所不同 .

    Personal account

    参考：Azure Active Directory v2.0 tokens reference

    可以在ID令牌中发布与用户帐户关联的电子邮件地址 .

    1）将“范围”元数据项从“openid profile”更改为“openid profile email” .

    <Metadata>
  <Item Key="scope">openid profile email</Item>
</Metadata>

    2）更改“电子邮件”输出声明：

    <OutputClaim ClaimTypeReferenceId="email" PartnerClaimType="unique_name" />

    至：

    <OutputClaim ClaimTypeReferenceId="email" PartnerClaimType="email" />

    Work account

    必须使用Microsoft Graph API检索与用户帐户关联的电子邮件地址 .

    1）将"AzureADAccountProfile"技术配置文件从"OpenIdConnect"更改为"OAuth2"，并将元数据项添加到retrieve the profile properties for the signed-in user .

    注意："Get a user"操作不返回已登录用户的租户标识符，因此以下技术配置文件将从此用户的"userPrincipalName"属性的域部分创建备用安全标识符所需的"identityProvider"声明 .

    <TechnicalProfile Id="AzureADAccountProfile">
  <DisplayName>Log in with your work account</DisplayName>
  <Protocol Name="OAuth2"/>
  <OutputTokenFormat>JWT</OutputTokenFormat>
  <Metadata>
    <Item Key="AccessTokenEndpoint">https://login.microsoftonline.com/organizations/oauth2/v2.0/token</Item>
    <Item Key="authorization_endpoint">https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize</Item>
    <Item Key="BearerTokenTransmissionMethod">AuthorizationHeader</Item>

    <Item Key="DiscoverMetadataByTokenIssuer">true</Item>
    <Item Key="HttpBinding">POST</Item>

    <Item Key="response_types">code</Item>

    <OutputClaim ClaimTypeReferenceId="givenName" PartnerClaimType="givenName" />
    <OutputClaim ClaimTypeReferenceId="surname" PartnerClaimType="surname" />
    <OutputClaim ClaimTypeReferenceId="socialIdpUserId" PartnerClaimType="id" />
    <OutputClaim ClaimTypeReferenceId="userPrincipalName" PartnerClaimType="userPrincipalName" />
  </OutputClaims>
  <OutputClaimsTransformations>
    <OutputClaimsTransformation ReferenceId="CreateAzureADIdentityProvider" />
    <OutputClaimsTransformation ReferenceId="CreateAlternativeSecurityId" />
    <OutputClaimsTransformation ReferenceId="CreateRandomUPNUserName" />
    <OutputClaimsTransformation ReferenceId="CreateUserPrincipalName" />
  </OutputClaimsTransformations>
  <UseTechnicalProfileForSessionManagement ReferenceId="SM-Noop" />
</TechnicalProfile>

    2）创建“CreateAzureADIdentityProvider”声明转换 .

    <ClaimsTransformation Id="CreateAzureADIdentityProvider" TransformationMethod="ParseDomain">
  <InputClaims>
    <InputClaim ClaimTypeReferenceId="userPrincipalName" TransformationClaimType="emailAddress" />
  </InputClaims>
  <OutputClaims>
    <OutputClaim ClaimTypeReferenceId="identityProvider" TransformationClaimType="domain" />
  </OutputClaims>
</ClaimsTransformation>
