lambda 中的 AWS Cognito 用户池 AdminCreateUser 不返回错误也不返回数据

【中文标题】lambda 中的 AWS Cognito 用户池 AdminCreateUser 不返回错误也不返回数据

【英文标题】：AWS Cognito User Pool AdminCreateUser in lambda returns no error nor data

【问题描述】：

我创建了一个 AWS Lambda 函数来测试新 Cognito 用户池帐户的创建，但没有在用户池中创建帐户，并且控制台日志中没有显示错误。我检查了 AWS Cloud Watch，但 Cloud Watch 也没有报错。

START RequestId: ..... Version: $LATEST
END RequestId: .....
REPORT RequestId: .....  Duration: 80.12 ms  Billed Duration: 100 ms Memory Size: 128 MB Max Memory Used: 84 MB  

我将 Lambda 函数更改为更简单的函数；描述用户池。仍然没有引发错误，并且控制台中没有打印任何用户池信息。我在 describeUserPool 回调函数中添加了一个 console.log 打印，但没有打印。

lambda 函数是使用 AWS 控制台 Lambda 内联编辑器创建的。 Lambda 函数附加了 AmazonESCognitoAccess 策略（此策略具有对 Cognito 用户池的列表/读取/写入访问级别）。

谁能解释我做错了什么？ 非常感谢您。

var aws = require('aws-sdk');
aws.config.update(
    accessKeyId: 'access_key_id', 
    secretAccessKey: 'secret_access_key',
    region: 'us-east-1',
    apiVersion: '2016-04-18'
);
var cognito = new aws.CognitoIdentityServiceProvider();
var params = 
    UserPoolId: 'us-region-user-pool-id'
;

exports.handler = async (event) => 
    cognito.describeUserPool(params, function(err, data) 
        console.log('hello from inside function');
        if (err) 
            console.log(err);
         else 
            console.log(data);
        
     );
;

如果我在 AdminCreateUser 中包含不正确的参数，它会报告错误

var aws = require('aws-sdk');
    aws.config.update(
        accessKeyId: 'access_key_id', 
        secretAccessKey: 'secret_access_key',
        region: 'us-east-1',
        apiVersion: '2016-04-18'
    );


var cognito = new aws.CognitoIdentityServiceProvider();
var params = 
    UserPoolId: 'us-region-user-pool-id'
    Username: 'someone',
    TemporaryPassword: '11223344',
    DesiredDeliveryMediums: 'EMAIL',
    MessageAction: 'SUPPRESS',
    UserAttributes: [
    
      Name: 'Email',
      Value: '[e-mail]'
    ,
    
        Name: 'Family_Name',
        Value: 'One'
    ,
    
        Name: 'Given_Name',
        Value: 'Some'
    ,
    
        Name: 'Phone_Number_verified',
        Value: 'True'
    ,
        
        Name: 'Email_verified',
        Value: 'True'
    

  ],
;

exports.handler = async (event) => 

    cognito.adminCreateUser(params, function(err, data) 
        console.log('hello from inside function');
        if (err) 
            console.log(err);
         else 
            console.log(data);
        
     );
;

我在 Lambda 内联编辑器控制台中收到以下错误消息：

嗨，你能看看它是否被调用。检查 CloudWatch 指标

在 Lambda 控制台中触发了“测试”，Cloud Watch 确认它运行了 successfully. Timestamp Message There are older events to load. Load more. 2020-05-31T16:59:07.766-04:00 START RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Version: $LATEST 2020-05-31T16:59:08.202-04:00 END RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 2020-05-31T16:59:08.202-04:00 REPORT RequestId: 1ea1741e-d9e7-4991-af9d-f72bf73b1133 Duration: 434.49 ms Billed Duration: 500 ms Memory Size: 128 MB Max Memory Used: 83 MB Init Duration: 337.21 ms。但是，Cognito 没有 CloudWatch 指标。

我将函数调用改回 AdminCreateUser。这并没有产生任何 CloudWatch 日志。看起来 lambda 根本没有触发 CognitoIdentifyServiceProvider 函数调用。

【参考方案1】：

找到这个帖子cognito admin not giving error。 @thopaw 的建议解决了我遇到的问题。

通过将其更改为 promise() 基础，它可以按预期工作。 谢谢你们的时间。

如果有人遇到这个，下面是更新的代码。

exports.handler = async (event, context) => 
    console.log('starts');
    var data;
    try 
        const data = await cognito.adminCreateUser(params).promise();
     catch (error) 
        console.log(error);
    
;
