How to turn a String accessToken to a TokenCredential for use in Java SDK

Question

Hi,

I am performing an Oauth2.0 flow and am able to get a access and refresh token via a Authorization Code flow. I would then like to use the access token to call the Graph API. The issue is that the accessToken I have is a String, while the API takes a TokenCredential. I made the following class, but it feels a bit odd that this capability does not come 'out of the box' with the API:


import com.azure.core.credential.AccessToken;
import com.azure.core.credential.TokenCredential;
import com.azure.core.credential.TokenRequestContext;
import reactor.core.publisher.Mono;

public class ManualTokenCredential implements TokenCredential {

    private final AccessToken accessToken;

    public ManualTokenCredential(AccessToken accessToken) {
        this.accessToken = accessToken;
    }

    @Override
    public Mono getToken(TokenRequestContext request) {
        return Mono.fromCallable(() -> accessToken);
    }
}

See https://video2.skills-academy.com/en-us/answers/questions/1555278/how-can-i-initialize-graphserviceclient-by-providi for a C# answer, but I need one in Java.

What is the 'correct' way to do this?

Answer

Hello GZ,

Thank you for reaching Microsoft Support!

You can use the graph sdk to access the Graph Api. After creating the graphClient object, you can directly call the corresponding methods through the object to access the Api. For details, see this document.

Hope this helps.
