AWS Cognito GetCredentialsForIdentity

Question

Map<String, String> logins = new HashMap();
logins.put("cognito-identity.amazonaws.com", cognitoOpenIdToken);
GetCredentialsForIdentityRequest getCredentialsRequest = 
  new GetCredentialsForIdentityRequest()
  .withIdentityId(cognitoIdentityId)
  .withLogins(logins);
AmazonCognitoIdentityClient cognitoIdentityClient = 
  new AmazonCognitoIdentityClient();
GetCredentialsForIdentityResult getCredentialsResult = 
  cognitoIdentityClient.getCredentialsForIdentity(getCredentialsRequest);

我是不是错过了一些简单的东西？

Answer 1

您是否尝试过以以下方式初始化AmazonCognitoIdentityClient？

新的AmazonCognitoIdentityClient（新的AnonymousAWSCredentials（））；

否则，根据AWS Java SDK的设计，服务客户机将查找AWS凭据，因为相同的客户机也可以用于访问经过身份验证的API。
