我正在尝试设置一个本机 Java 应用程序,该应用程序将利用 MS Graph 的 API 在使用 ADAL4j 进行身份验证后访问用户 OneDrive。我正在使用这个库来获取我的访问令牌。到目前为止,我有这个代码:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
import javax.naming.ServiceUnavailableException;
import com.microsoft.aad.adal4j.AuthenticationContext;
import com.microsoft.aad.adal4j.AuthenticationResult;
public class Get {
private final static String AUTHORITY = "https://login.windows.net/common/oauth2/v2.0/authorize";
private final static String CLIENT_ID = "29275...011a";
private final static String RESOURCE = "https://graph.windows.net";
public static void main(String[] args) throws Exception {
try (BufferedReader br = new BufferedReader(new InputStreamReader(
System.in))) {
System.out.print("Enter username: ");
String username = br.readLine();
System.out.print("Enter password: ");
String password = br.readLine();
AuthenticationResult result = getAccessTokenFromUserCredentials(
username, password);
System.out.println("Access Token - " + result.getAccessToken());
System.out.println("Refresh Token - " + result.getRefreshToken());
System.out.println("ID Token - " + result.getIdToken());
System.out.println("Expires in - " + result.getExpiresAfter());
}
}
private static AuthenticationResult getAccessTokenFromUserCredentials(
String username, String password) throws Exception {
AuthenticationContext context = null;
AuthenticationResult result = null;
ExecutorService service = null;
try {
service = Executors.newFixedThreadPool(1);
context = new AuthenticationContext(AUTHORITY, false, service);
Future<AuthenticationResult> future = context.acquireToken(RESOURCE, CLIENT_ID, username, password, null);
result = future.get();
} finally {
service.shutdown();
}
if (result == null) {
throw new ServiceUnavailableException(
"authentication result was null");
}
return result;
}
}
当我运行它时,我输入帐户凭据,然后打印访问令牌、刷新令牌、ID 令牌和过期时间。然后,我使用 chromes “Advanced Rest Client”插件来测试身份验证令牌(下面的屏幕截图)。
然后我得到了屏幕截图底部显示的访问令牌验证错误。我不明白令牌不起作用的原因。我在 Azure AD 中注册的应用程序上设置了权限,并且用户已经授予了该应用程序的权限。我唯一能想到的可能是没有指定范围,但我不确定这是问题所在。如果是我如何指定它们?
