NodeJs 从联合身份池获取 Accesskey 密钥和会话令牌

Question

我无法使用 aws.config.credentials.get() 方法获取访问密钥、密钥以及会话令牌。我拥有以上所有内容，例如身份验证和角色工作。

AWS.Config.credentials = new AWS.CognitoIdentityCredentials({
                IdentityPoolId: poolid,
                'cognito-idp.us-east-1.amazonaws.com/us-east-1_aWAJIClAA' : result.getIdToken().getJwtToken()
            });
            console.log("Config.credentials "+ AWS.Config.credentials);

            AWS.Config.credentials.get(function () {
                console.log("credentials called ", AWS.Config.credentials);
                // Credentials will be available when this function is called.

                console.log("Access Key" + AWS.Config.credentials.accessKeyId );

                console.log("Secret Key" + AWS.Config.credentials.secretAccessKey );

                console.log("Session Token" + AWS.Config.credentials.sessionToken );

用户使用

session

 登录后，您可以获得 

user.getSession(callback)

变量

import AWS from 'aws-sdk';

const authenticator = `cognito-idp.${process.env.REACT_APP_AWS_REGION}.amazonaws.com/${process.env.REACT_APP_COGNITO_USER_POOL_ID}`
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityPoolId : process.env.IDENTITY_POOL_ID, 
    Logins : {
             [authenticator]: session.getIdToken().getJwtToken()
    }
});
