我有一个Web应用程序,可以让用户轻松管理AWS资源,就像使用GUI启动Ec2实例一样。不同的用户可以使用此Web应用程序。我已经实现了自己的用户管理。某些用户可能不希望为我的Web应用程序创建帐户并存储其凭据以向AWS资源发出请求。它们可能不安全。所以,我想使用以下流程构建一个机制。
通过这种方式,我的网络应用程序中不会存储永久凭证。
我正在使用java作为我的后端服务。那么有没有AWS APi这样做呢?
我尝试过以下代码:
val client = new AmazonCognitoIdentityClient(new AnonymousAWSCredentials())
val idRequest = new GetIdRequest();
idRequest.setAccountId(account-id);
idRequest.setIdentityPoolId("us-east-1:xxxx");
// If you are authenticating your users through an identity provider
// then you can set the Map of tokens in the request
val logins = new HashMap[String, String]()
providerTokens+=("www.amazon.com"->"Atza|IwE-xxxxxxxxxxxxxxxxxxx")
idRequest.setLogins(logins);
val idResp = client.getId(idRequest)
val identityId = idResp.getIdentityId()
// Create the request object
val tokenRequest = new GetOpenIdTokenRequest();
tokenRequest.setIdentityId("us-east-1:xxxxxx");
//
val tokenResp = client.getOpenIdToken(tokenRequest);
// get the OpenID token from the response
val openIdToken = tokenResp.getToken()
// you can now create a set of temporary, limited-privilege credentials to access
// your AWS resources through the Security Token Service utilizing the OpenID
// token returned by the previous API call. The IAM Role ARN passed to this call
// will be applied to the temporary credentials returned
val stsClient = new AWSSecurityTokenServiceClient(new AnonymousAWSCredentials());
val stsReq = new AssumeRoleWithWebIdentityRequest();
stsReq.setRoleArn("arn:aws:iam::account-id:role/Cognito_Auth_Role");
stsReq.setWebIdentityToken(openIdToken);
stsReq.setRoleSessionName("AppTestSession");
val stsResp = stsClient.assumeRoleWithWebIdentity(stsReq);
val stsCredentials = stsResp.getCredentials();
我收到以下错误:
禁止访问身份'us-east-1:xxxxxxxxxxxxxxxx'。 (服务:AmazonCognitoIdentity;状态代码:400;错误代码:NotAuthorizedException
以下是IAM角色中的Cognito_Auth_Role角色策略:
{
"Version": "2012-10-17",
"Statement":[{
"Effect":"Allow",
"Action":"cognito-sync:*",
"Resource":["arn:aws:cognito-sync:us-east-1:xxxxxxx:identitypool/${cognito-identity.amazonaws.com:aud}/identity/${cognito-identity.amazonaws.com:sub}/*"]
}]
}
以下是此角色的信任关系:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "",
"Effect": "Allow",
"Principal": {
"Federated": "cognito-identity.amazonaws.com"
},
"Action": "sts:AssumeRoleWithWebIdentity",
"Condition": {
"StringEquals": {
"cognito-identity.amazonaws.com:aud": "us-east-1:xxxxx"
},
"ForAnyValue:StringLike": {
"cognito-identity.amazonaws.com:amr": "www.amazon.com"
}
}
}
]
}
请指出我,这里有什么问题?

您可以使用AWS Cognito处理大部分管道,也可以连接您自己的OpenId Identity Provider或您订阅的提供商服务。
以下是身份和访问管理(IAM)的文档: https://aws.amazon.com/documentation/iam/
或者你可以让他们为Cognito做一些管道工作: http://docs.aws.amazon.com/cognito/latest/developerguide/what-is-amazon-cognito.html
虽然它看起来只适用于移动设备,但他们有关于在浏览器中使用JavaScript SDK的文档: http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/browser-intro.html
