SDK的问题:amazon-cognito identity-js

Question

我从aws-cognito开始。我已经在亚马逊平台上创建了一个UserPool和一个UserPoolClient。我正在实现一个执行用户注册的lambda (作为测试)。但是尝试用邮递员运行它时，会返回"Internal Server Error“。这是我的Lambda的代码。

module.exports.register = async event => {

  var AmazonCognitoIdentity = require('amazon-cognito-identity-js');
  var CognitoUserPool = AmazonCognitoIdentity.CognitoUserPool;

  var poolData = {
    UserPoolId: '...', // Here, I put my UserPoolId
    ClientId: '...' // Here, I put my ClientId
  };
  var userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
  var attributeList = [];

  var dataEmail = {
    Name: 'email',
    Value: 'myemail@gmail.com'
  };

  var dataPhoneNumber = {
    Name: 'phone_number',
    Value: '+15555555555'
  };
  var attributeEmail = new AmazonCognitoIdentity.CognitoUserAttribute(dataEmail);
  var attributePhoneNumber = new AmazonCognitoIdentity.CognitoUserAttribute(dataPhoneNumber);

  attributeList.push(attributeEmail);
  attributeList.push(attributePhoneNumber);
  var cognitoUser = ''
  userPool.signUp('myemail@gmail.com', 'MyPassword7.com', attributeList, null, function (err, result) {
    if (err) {
      cognitoUser = err;
    }
    cognitoUser = result.user;
  });
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Go Serverless v1.0! Your function executed successfully!',
        input: event,
        cognitoUser: cognitoUser
      },
      null,
      2
    ),
  };

我认为您需要在响应中添加适当的标头

      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Credentials': true,
        'Content-Type': 'application/json',
      },
