To refresh an expired token when using the IGraphClient, you need to implement a mechanism that checks the token’s validity and retrieves a new token when necessary. This typically involves using an ITokenProvider that can handle the authentication process.

Here’s a general approach you can follow:

  1. Implement ITokenProvider: Create a class that implements the ITokenProvider interface. This class should manage the token lifecycle, including obtaining a new token when the current one expires.

  2. Check Token Expiry: Before making a request with the IGraphClient, check if the current token is still valid. If it has expired, use your ITokenProvider to fetch a new token.

  3. Use the New Token: Once you have a new token, update the IGraphClient instance to use this token for subsequent requests.

Here is a simplified code example to illustrate this:

public class MyTokenProvider implements ITokenProvider {
    private String token;
    private long expiryTime;

    public String getToken() {
        if (isTokenExpired()) {
            token = fetchNewToken(); // Implement this method to get a new token
            expiryTime = System.currentTimeMillis() + TOKEN_LIFETIME; // Set the new expiry time
        }
        return token;
    }

    private boolean isTokenExpired() {
        return System.currentTimeMillis() >= expiryTime;
    }
}

// Usage
ITokenProvider tokenProvider = new MyTokenProvider();
IGraphClient graphClient = new GraphClient(tokenProvider);

// Make requests using graphClient

This approach ensures that your application can seamlessly refresh the token and continue making requests to the Microsoft Graph API without interruption. For more detailed information on using IGraphClient, you can refer to the official documentation here.
