AWS Cognito的SMS多因素身份验证返回无效代码或身份验证状态

我正在尝试使用他们的Go Cognito来实现基于SDK构建的身份验证。我已经能够使用基本的username/password身份验证来工作,但是当我使用SMS进行2要素身份验证时,就会陷入困境。

复制步骤:

  1. 我使用用户名/密码和电子邮件验证来创建用户
  2. 我验证电子邮件地址
  3. 我设置了电话号码并要求输入验证码
  4. 我验证电话号码
  5. 我启用了2要素身份验证(通过短信)
  6. 我尝试登录并收到SMS_MFA挑战
  7. 我在手机上收到验证码,然后致电AdminRespondToAuthChallenge

问题,我收到一个error

CodeMismatchException: Invalid code or auth state for the user.
status code: 400, request id: 1513894e-8efa-11e8-a8f8-97e5e083c03b

SMS验证码肯定是正确的,因此似乎与auth状态有关。

对Cognito的呼叫如下:

c.cip.SignUp(&cognitoidentityprovider.SignUpInput{
        ClientId: aws.String(c.clientID),
        Username: aws.String(username),
        Password: aws.String(password),
        UserAttributes: []*cognitoidentityprovider.AttributeType{
            {
                Name:  aws.String("email"),
                Value: aws.String(email),
            },
            {
                Name:  aws.String("name"),
                Value: aws.String(fullName),
            },
        },
    })

c.cip.ConfirmSignUp(&cognitoidentityprovider.ConfirmSignUpInput{
    ClientId:         aws.String(c.clientID),
    Username:         aws.String(username),
    ConfirmationCode: aws.String(code),
})


//Add the phone number
c.cip.AdminUpdateUserAttributes(&cognitoidentityprovider.AdminUpdateUserAttributesInput{
            UserPoolId: aws.String(c.userPoolID),
            Username:   aws.String(username),
            UserAttributes: []*cognitoidentityprovider.AttributeType{
                {
                    Name:  aws.String("phone_number"),
                    Value: aws.String(phoneNumber),
                },
            },
        })

//Request a verification code
c.cip.GetUserAttributeVerificationCode(&cognitoidentityprovider.GetUserAttributeVerificationCodeInput{
    AccessToken:   aws.String(accessToken),
    AttributeName: aws.String("phone_number"),
})

//Verify the phone number
c.cip.VerifyUserAttribute(&cognitoidentityprovider.VerifyUserAttributeInput{
    AccessToken:   aws.String(accessToken),
    AttributeName: aws.String("phone_number"),
    Code:          aws.String(code),
})

//Enable SMS 2-factor auth c.cip.AdminSetUserSettings(&cognitoidentityprovider.AdminSetUserSettingsInput{
    UserPoolId: aws.String(c.userPoolID),
    Username:   aws.String(username),
    MFAOptions: []*cognitoidentityprovider.MFAOptionType{
        &cognitoidentityprovider.MFAOptionType{
            AttributeName:  aws.String("phone_number"),
            DeliveryMedium: aws.String("SMS"),
        },
    },
})

c.cip.AdminInitiateAuth(&cognitoidentityprovider.AdminInitiateAuthInput{
    ClientId:   aws.String(c.clientID),
    UserPoolId: aws.String(c.userPoolID),
    AuthFlow:   aws.String("ADMIN_NO_SRP_AUTH"),
    AuthParameters: map[string]*string{
        "USERNAME": aws.String(username),
        "PASSWORD": aws.String(password),
    },
})

c.cip.AdminRespondToAuthChallenge(&cognitoidentityprovider.AdminRespondToAuthChallengeInput{
        ClientId:      aws.String(c.clientID),
        UserPoolId:    aws.String(c.userPoolID),
        ChallengeName: aws.String("SMS_MFA"),
        Session:       aws.String(session),
        ChallengeResponses: map[string]*string{
            "USERNAME":     aws.String(username),
            "SMS_MFA_CODE": aws.String(code),
        },
    })

进行GetUser调用将显示用户的当前状态:

User = {
              Enabled: true,
              MFAOptions: [{
                  AttributeName: "phone_number",
                  DeliveryMedium: "SMS"
                }],
              PreferredMfaSetting: "SMS_MFA",
              UserAttributes: [
                {
                  Name: "sub",
                  Value: "bd2bb8bc-dfe6-4216-829c-5ae975ce24e5"
                },
                {
                  Name: "email_verified",
                  Value: "true"
                },
                {
                  Name: "name",
                  Value: "Ben Vogan"
                },
                {
                  Name: "phone_number_verified",
                  Value: "true"
                },
                {
                  Name: "phone_number",
                  Value: "<redacted>"
                },
                {
                  Name: "email",
                  Value: "<redacted>"
                }
              ],
              UserCreateDate: 2018-07-24 03:29:49 +0000 UTC,
              UserLastModifiedDate: 2018-07-24 04:19:51 +0000 UTC,
              UserMFASettingList: ["SMS_MFA"],
              UserStatus: "CONFIRMED",
              Username: "bd2bb8bc-dfe6-4216-829c-5ae975ce24e5"
            }

我不知道是否有一种查询用户的身份验证状态的方式,以便我可以验证。

AWS文档和无用的错误使我发疯,因此我们将不胜感激!

谢谢。

您的问题似乎模棱两可。

您是第2步

  1. 我设置了电话号码并要求输入验证码
  2. 我验证电话号码

这不过是Cognito中的MFA。如果您已正确配置池。

您不能同时拥有用于登录的手机和MFA。那没有道理。

但是,如果您有用于登录的电话,则Cognito将每次发送带有代码的SMS。密码仅用于电子邮件登录。
