我可以使用 ListUsers API 通过用户的 uuid 查询 Cognito 用户池吗？

Question

可在此处找到 Cognito 用户池的文档：

http://docs.aws.amazon.com/cognito/latest/developerguide/how-to-manage-user-accounts.html

这里没有说是否可以通过自动生成的子属性查询用户，是uuid。它明确表示您不能通过自定义属性搜索用户，但 sub/uuid 不是自定义属性。奇怪的是，在可搜索属性列表中 sub/uuid 不是其中之一。当然，虽然您可以通过用户的 UUID 查找用户，但这将如何完成？？

你知道，我使用过 COgnito，但从来不需要通过 sub（或用户名以外的其他参数）查找。我调查了它，因为你肯定可以，但它不是很清楚（就像他们的很多文档一样）。这是我看到的，您可以尝试...希望它对人有所帮助。

        // the imported ListUsersResult is...
        import com.amazonaws.services.cognitoidp.model.ListUsersRequest;
        import com.amazonaws.services.cognitoidp.model.ListUsersResult;

             // class var

         protected final AWSCognitoIdentityProviderClient identityUserPoolProviderClient;

        // omitted stuff... 
        // initialize the Cognito Provider client.  This is used to talk to the user pool
        identityUserPoolProviderClient = new AWSCognitoIdentityProviderClient(new BasicAWSCredentials(AWS_ACCESS_KEY, AWS_SECRET_KEY)); // creds are loaded via variables that are supplied to my program dynamically
        identityUserPoolProviderClient.setRegion(RegionUtils.getRegion(USER_POOL_REGION)); // var loaded 


        // ...some code omitted        
        ListUsersRequest listUsersRequest = new ListUsersRequest();
        listUsersRequest.withUserPoolId(USER_POOL_ID); // id of the userpool, look this up in Cognito console
        listUsersRequest.withFilter("sub=xyz");  // i THINK this is how the Filter works... the documentation is terribad


    // get the results 
    ListUsersResult result = identityUserPoolProviderClient.listUsers(listUsersRequest); 

    List<UserType> userTypeList = result.getUsers();
    // loop through them
    for (UserType userType : userTypeList) {
        List<AttributeType> attributeList = userType.getAttributes();
        for (AttributeType attribute : attributeList) {
            String attName = attribute.getName();
            String attValue = attribute.getValue();
            System.out.println(attName + ": " + attValue);
        }
    }

如果您有用户名，您可以获得这样的用户

    // build the request
    AdminGetUserRequest idRequest = new AdminGetUserRequest();
    idRequest.withUserPoolId(USER_POOL_ID);
    idRequest.withUsername(username);

    // call cognito for the result
    AdminGetUserResult result = identityUserPoolProviderClient.adminGetUser(idRequest);
    // loop through results

我可以使用 ListUsers API 通过用户的 uuid 查询 Cognito 用户池吗？

Can I use the ListUsers API to query a Cognito User Pool by a user's uuid?
