How can i get user objects by id or userPrincipalName using Graph API?

Question

I am trying to get users from Active Directory using Graph API. For this i am using a list of user id's.

    String selectQuery = "id,mail,givenName,surname,displayName,businessPhones,department,assignedLicense";
    List<Option> requestOptions = new LinkedList<>();
    requestOptions.add(new QueryOption("$select", selectQuery));
    IGraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(new SimpleAuthProvider(accessToken)).buildClient();

    List<User> users = new ArrayList<>();
    for (String userID : userList) {
        IUserRequest request = graphClient
                .users()
                .byId(userID)
                .buildRequest(requestOptions);
        users.add(request.get());
    }

    return users;

Using the code above i receive the input below.

[com.microsoft.graph.models.extensions.User@5042e9c3, com.microsoft.graph.models.extensions.User@1c9fc2e2]

I would like to receive user resource fields(such as mail, givenName, surname, displayName, businessPhones etc.) for users which i am searching. I used a sample query in Graph Explorer. But i fail to get multiple users with java sdk. How can i achieve this?

Answer 1

Your code is correct and you have got the users.

You need to poll users and get their corresponding attributes, like this:

for (User user : users) {
    System.out.println("id:" + user.id + " mail:" + user.mail + " displayName:" + user.displayName);
}
