在 AppSync 中,当您将 Cognito 用户池用作身份验证设置时,您会得到:
identity:
{ sub: 'bcb5cd53-315a-40df-a41b-1db02a4c1bd9',
issuer: 'https://cognito-idp.us-west-2.amazonaws.com/us-west-2_oicu812',
username: 'skillet',
claims:
{ sub: 'bcb5cd53-315a-40df-a41b-1db02a4c1bd9',
aud: '7re1oap5fhm3ngpje9r81vgpoe',
email_verified: true,
event_id: 'bb65ba5d-4689-11e8-bee7-2d0da8da81ab',
token_use: 'id',
auth_time: 1524441800,
iss: 'https://cognito-idp.us-west-2.amazonaws.com/us-west-2_oicu812',
'cognito:username': 'skillet',
exp: 1524459387,
iat: 1524455787,
email: 'myemail@nope.com' },
sourceIp: [ '11.222.33.200' ],
defaultAuthStrategy: 'ALLOW',
groups: null }
然而,当您使用AWS_IAM身份验证时,会得到
identity:
{ accountId: '12121212121', //<--- my amazon account ID
cognitoIdentityPoolId: 'us-west-2:39b1f3e4-330e-40f6-b738-266682302b59',
cognitoIdentityId: 'us-west-2:a458498b-b1ac-46c1-9c5e-bf932bad0d95',
sourceIp: [ '33.222.11.200' ],
username: 'AROAJGBZT5A433EVW6O3Q:CognitoIdentityCredentials',
userArn: 'arn:aws:sts::454227793445:assumed-role/MEMORYCARDS-CognitoAuthorizedRole-dev/CognitoIdentityCredentials',
cognitoIdentityAuthType: 'authenticated',
cognitoIdentityAuthProvider: '"cognito-idp.us-west-2.amazonaws.com/us-west-2_HighBob","cognito-idp.us-west-2.amazonaws.com/us-west-2_HighBob:CognitoSignIn:1a072f08-5c61-4c89-807e-417d22702eb7"' }
文档说明了这是预期现象,https://docs.aws.amazon.com/appsync/latest/devguide/resolver-context-reference.html 。 然而,如果您使用连接到Cognito的
AWS_IAM
(需要未经身份验证的访问),那么您应该如何获取用户的用户名、电子邮件、sub等信息?在使用AWS_IAM
类型的身份验证时,我需要访问用户的声明。
