Question

我正在尝试在节点中验证cognito用户池用户，但在刷新凭据时遇到错误（404）。我尝试使用cognitoUser.authenticateUser进行身份验证。这很成功，在onSuccess中，我使用AWS.CognitoIdentityCredentials创建凭据并获取以下内容

CognitoIdentityCredentials {
expired: true,
expireTime: null,
accessKeyId: undefined,
sessionToken: undefined,
params: 
 { IdentityPoolId: '...',
   Logins: 
    { 'cognito...': '...' } },
data: null,
_identityId: null,
_clientConfig: {} }

所以我尝试使用AWS.config.credentials.refresh刷新凭据，但是我收到此错误

  retryDelay: 81.76059666489807 }

注意：这些是我需要的两个库

const AWS = require('aws-sdk');
const AWSCognito = require('amazon-cognito-identity-js');

我按照说明here进行操作。具体用例4

Answer 1

我认为我的问题是我的终端设置为发电机。在AWS配置中更改了端点后，我收到了另一个错误

Answer 2

( < AWS.CognitoIdentityCredentials > AWS.config.credentials).refresh((error) => {});

刷新凭据Cognito Identity时出错
