TokenResponseException：尝试访问Admin SDK Google API时出现401 Unauthorized Exception。
我正在尝试通过访问Google Admin SDK API对我的域中的用户进行提取。 然而，我获得了401未经授权的例外。 下面的代码是我的设置类，其中包含调用API的方法。
package com.brookfieldres.operations; import java.io.File; import java.io.IOException; import java.security.GeneralSecurityException; import java.util.ArrayList; import java.util.ResourceBundle; import org.apache.log4j.Logger; import com.brookfieldres.common.Constants; import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; import com.google.api.client.googleapis.auth.oauth2.GoogleCredential.Builder; import com.google.api.services.admin.directory.Directory; import com.google.api.services.admin.directory.DirectoryScopes; public class GCAuthentication { private static final Logger _Log = Logger.getLogger(GCAuthentication.class.getName()); static ResourceBundle resources = ResourceBundle.getBundle("Resources"); // public static String serviceAcc = resources.getString("SERVICE_ACC_EMAIL"); // public static String privKeyPath = resources.getString("PRIVATE_KEY_PATH"); // public static String userEmail = resources.getString("ADMIN_ACC"); public static Directory getDirectoryService(String serviceAcc, String privKeyPath, String userEmail) throws IOException, GeneralSecurityException, NullPointerException { // final ArrayList dirScopes = new ArrayList(); // dirScopes.add(DirectoryScopes.ADMIN_DIRECTORY_USER); Constants.dirScopes = new ArrayList(); Constants.dirScopes.add(DirectoryScopes.ADMIN_DIRECTORY_USER); Constants.dirScopes.add(DirectoryScopes.ADMIN_DIRECTORY_CUSTOMER); Constants.dirScopes.add(DirectoryScopes.ADMIN_DIRECTORY_ORGUNIT); GoogleCredential gCreds = new GoogleCredential.Builder() .setJsonFactory(Constants.JSON_FACTORY) .setTransport(Constants.HTTP_TRANSPORT) .setServiceAccountId(serviceAcc) .setServiceAccountUser(userEmail) .setServiceAccountPrivateKeyFromP12File(new File(privKeyPath)) .setServiceAccountScopes(Constants.dirScopes) .build(); Directory directory = new Directory.Builder(Constants.HTTP_TRANSPORT, Constants.JSON_FACTORY, gCreds).setApplicationName(Constants.APPLICATION_NAME).build(); return directory; } } 下面的代码是我用来从我的域中提取用户的测试用例：
package com.brookfieldres.library.test; import org.junit.Before; import org.junit.Test; import static org.junit.Assert.assertFalse; import java.io.IOException; import java.security.GeneralSecurityException; import org.junit.After; import com.brookfieldres.operations.GCAuthentication; import com.google.api.client.repackaged.com.google.common.base.Strings; import com.google.api.services.admin.directory.Directory; import com.google.api.services.admin.directory.model.Customer; import com.google.api.services.admin.directory.model.User; public class ExtractionTest { @Before public void setUp(){} @Test public void getEmails() throws IOException, NullPointerException, GeneralSecurityException{ try { Directory directory = GCAuthentication.getDirectoryService("XXXXXXX", "XXXXXXXX", "XXXXXXX"); System.out.println("The connection to Google is established"); User user1 = directory.users().get("XXXXXXXX@XXXX.ca").execute(); System.out.println("User is pulled."); // assertFalse(user1 == null); // if(user1 != null){ // System.out.println("Name= " + user1.getName()); // } }catch(NullPointerException e) { e.printStackTrace(); }catch (IOException e){ e.printStackTrace(); }catch (GeneralSecurityException e) { e.printStackTrace(); } } @After public void tearDown(){ } }
最后这是我面临的例外。

基于此线程 ， TokenResponseException：401 Unauthorized在具有无效的客户端ID，客户端密钥或范围时发生。 但也可能是因为刷新令牌过度使用。 如有必要， 刷新访问令牌 ，因为它的生命周期有限。 如果您的应用需要在单个访问令牌的生命周期之后访问Google API，则可以获取刷新令牌。 刷新令牌允许您的应用程序获取新的访问令牌。
检查这些相关的线程：
- Java Google联系人API访问服务帐户身份validation ，其中指出“401 Unauthorized”exception的另一个可能来源是离开
credential.refreshToken()。 要将访问代码写入引用，必须进行调用。 - 总是得到TokenResponseException：401 Unauthorized。
希望这可以帮助！
尝试删除.credential目录 – 在本地计算机中创建。 这很有效。
