Question

Amazon-cognito-identity-js，在尝试更改经过身份验证的用户的密码时出现“callback.newPasswordRequired 不是函数”错误

const poolData = {
  UserPoolId: 'eu-central-1_XXXXXXX'
  ClientId: '2xxxxxxxxxxxxxxxxxxo',
}
const authenticationData = {
  Username: name,
  Password: oldPassword,
}
const authenticationDetails = new AuthenticationDetails(authenticationData)
const userPool = new CognitoUserPool(poolData)
const cognitoUser = new CognitoUser({ Username: name, Pool: userPool })

cognitoUser.authenticateUser(authenticationDetails, {
  onSuccess(result) {
    cognitoUser.changePassword(oldPassword, newPassword, function (err, passwordChangeResult) {
      if (err) {
        console.warn(err.message || JSON.stringify(err))
      }
      console.warn(`Password change result: ${passwordChangeResult}`)
    })
  },
  onFailure(err) {
    console.warn(err)
  },
})
return null
}

似乎 Cognito 正在返回一个您尚未定义的 newPasswordRequired 回调。我会假设用户是由 Admin API 调用而不是通过 Sign Up 调用创建的。然后在登录时，系统会提示您重置密码。

取自这里 [1]，您可以像这样实现 newPasswordRequired 回调。

cognitoUser.authenticateUser(authenticationDetails, {
        onSuccess: function (result) {
            // User authentication was successful
        },

        onFailure: function(err) {
            // User authentication was not successful
        },
 
        mfaRequired: function(codeDeliveryDetails) {
            // MFA is required to complete user authentication.
            // Get the code from user and call
            cognitoUser.sendMFACode(mfaCode, this)
        },
 
        newPasswordRequired: function(userAttributes, requiredAttributes) {
            // User was signed up by an admin and must provide new
            // password and required attributes, if any, to complete
            // authentication.
 
            // the api doesn't accept this field back
            delete userAttributes.email_verified;
 
            // store userAttributes on global variable
            sessionUserAttributes = userAttributes;
        }
    });
