【问题描述】：

我使用 Amplify CLI 创建了一个 Lambda 函数，执行 Lambda 函数时执行没有错误，但未创建 Cognito 用户。

我在这里错过了什么？

我已经检查了 CloudWatch Logs，但也没有我可以获取的错误。

我一直在关注这个文档：https://docs.aws.amazon.com/AWSjavascriptSDK/latest/AWS/CognitoIdentityServiceProvider.html#adminCreateUser-property

/* Amplify Params - DO NOT EDIT
    AUTH_XXXXXXXXXXXXXXXXXXXX_USERPOOLID
    ENV
    REGION
Amplify Params - DO NOT EDIT */

const AWS = require('aws-sdk');
AWS.config.update( region: process.env.AWS_REGION,accessKeyId: process.env.AWS_ACCESS_KEY_ID, secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY );

const cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider( apiVersion: '2016-04-18' );

//console.log(process.env);

exports.handler = async (event) => 
    let retailerid = event.pathParameters.retailerid;

    let params = 
        UserPoolId: process.env.AUTH_XXXXXXXXXXXXXXXXXXXX_USERPOOLID, /* required */
        Username: 'testtest', /* required */
        ClientMetadata: 
        ,
        DesiredDeliveryMediums: [
            'EMAIL'
        ],
        ForceAliasCreation: false,
        MessageAction: 'SUPPRESS',
        TemporaryPassword: 'mynuw000000000TTS',
        UserAttributes: [
            
                Name: 'custom:app_role', /* required */
                Value: 'retail'
            ,
            
                Name: 'email_verified', /* required */
                Value: 'true'
            ,
            
                Name: 'email', /* required */
                Value: '[e-mail]'
            ,
            
                Name: 'phone_number', /* required */
                Value: '27833260000'
            ,
            /* more items */
        ],
        ValidationData: [

            /* more items */
        ]
    ;
    await cognitoidentityserviceprovider.adminCreateUser(params, function (err, data) 
        if (err) console.log(err, err.stack); // an error occurred
        else console.log('SUCCESS', data);           // successful response
    );

    // TODO implement
    const response = 
        statusCode: 200,
        //  Uncomment below to enable CORS requests
        headers: 
            "Access-Control-Allow-Origin": "*"
        ,
        body: JSON.stringify(retailerid),
    ;
    return response;
;

测试活动

 "request": 
"userAttributes": 
  "custom:name": "Ajay",
  "email": "[e-mail]",
  "custom:role": "Admin"

,
"response":

Lambda 函数

var AWS = require('aws-sdk');

var resp200ok =  statusCode: 200, headers: 'Content-Type': 'application/json', body:  ;

var cognitoidentityserviceprovider = new 
       AWS.CognitoIdentityServiceProvider(apiVersion: '2016-04-18');


exports.handler = function(event, context, callback)
const attributes = event.request.userAttributes;  // read user attributes from event

console.log('User Role : ',attributes['custom:role'])

 var params = 
    UserPoolId:'*********',
    Username: attributes.email,
    //TemporaryPassword: 'Password!1',
    DesiredDeliveryMediums: ["EMAIL"],
    UserAttributes: [
       
            Name: "email",
            Value: attributes.email
      ,
      
            Name: 'email_verified', /* required */
            Value: 'true'
      ,
      
            Name: 'custom:name', /* required */
            Value: attributes['custom:name']
      ,
      
            Name: 'custom:role', /* required */
            Value: attributes['custom:role']
      ,
    ],
;

cognitoidentityserviceprovider.adminCreateUser(params, function(err, data) 
          if (err) console.log(err, err.stack); // an error occurred
          else     console.log('SUCCESS', data);           // successful response
);

;

【参考方案2】：

我不确定 await 是否有效。这个怎么样。

var createUserPromise = cognitoidentityserviceprovider.adminCreateUser(params).promise();

createUserPromise.then(results => 
    // TODO implement
    const response = 
        statusCode: 200,
        //  Uncomment below to enable CORS requests
        headers: 
            "Access-Control-Allow-Origin": "*"
        ,
        body: JSON.stringify(retailerid),
    ;
    return response;
    )
   .catch(err => 
          console.log("Error: ", err);
          return "err"
        );

【参考方案3】：

await cognitoidentityserviceprovider.adminCreateUser(params).promise()
  .then((data) => 
    console.log('SUCCESS', data);  
  )
  .catch((error) => 
    console.log('ERROR', error);  
  );

这会起作用
