调用 users().list().execute() 时，Google Directory API 返回 Not Authorized [英] Google Directory API returns Not Authorized when call users().list().execute()

问题描述

我需要从我的 google 域中读取用户(和群组)列表.

I need to read the list of users (and groups) from my google domain.

所以我转到了我的 Google API 控制台并启用了 Admin SDK 并创建了一个 服务帐户来调用 Google API.我使用以下谷歌图书馆

So I went to my Google APIs Console and enabled Admin SDK and created a Service Account to call Google APIs. I use the following google libraries

• google-api-services-admin-directory_v1-rev11-1.16.0-rc.jar
• google-api-client-1.16.0-rc.jar

我的代码是

     /*
     * Global instance of the JSON factory.
     */
    final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
     /*
      Global instance of the HTTP transport.
     */
        HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();

        Collection<String> scopeList = new ArrayList<>();
        scopeList.add(DirectoryScopes.ADMIN_DIRECTORY_USER);
        scopeList.add(DirectoryScopes.ADMIN_DIRECTORY_GROUP);
        scopeList.add(DirectoryScopes.ADMIN_DIRECTORY_GROUP_MEMBER);

        GoogleCredential credential = new GoogleCredential.Builder()
                .setTransport(httpTransport)
                .setJsonFactory(JSON_FACTORY)
                .setServiceAccountId("[e-mail]")
                .setServiceAccountScopes(scopeList)
                .setServiceAccountPrivateKeyFromP12File(new File("/Path/To/KeyFile/nnnnn-privatekey.p12"))
//                .setServiceAccountUser("[e-mail]")
                .build();

        Directory admin = new Directory.Builder(httpTransport, JSON_FACTORY, credential)
                .setApplicationName("Test")
                .setHttpRequestInitializer(credential).build();


        Users users = admin.users().list().setDomain("mydomain.org").execute();

我在最后一行收到这个

错误

  "code" : 403,
  "errors" : [ {
    "domain" : "global",
    "message" : "Not Authorized to access this resource/api",
    "reason" : "forbidden"
  } ],

    at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:460)

如果我取消注释注释行 (.setServiceAccountUser("[e-mail]")) 然后我得到一个不同的错误

If I uncomment the commented line (.setServiceAccountUser("[e-mail]")) then I get a different error

    at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:460)

我的帐户 ([e-mail]) 是超级管理员.我怀疑需要授予服务帐户访问用户 API 范围的权限.但是我找不到可以授予此访问权限的位置.我的 Google CPanel 有一个经典的 UI 模式.而且我在高级工具中没有管理客户端 API 访问"页面.

My account ([e-mail]) is a super administrator. I suspect the Service Account needs to be granted access for the users API scope. But I can not find where I can grant this access. I have a classic UI mode of my Google CPanel. And I don't have "Manage client API access" page in the Advanced tools.

此外，我不确定在 .setApplicationName("Test") 处应该使用什么作为应用程序名称.

Also I'm not sure what I should use as an Application Name at .setApplicationName("Test").

感谢您的帮助

推荐答案

Google Directory API 与 Compute Engine 默认服务帐户配合使用，您无需在域范围内设置 Google Drive.唯一的事情:您必须设置 serviceAccountUser，这在基于 JSON 的凭据中不受支持.所以你可以

Google Directory API works with Compute Engine default service account, you do not need to setup Google Drive domain-wide. The only thing: you have to set serviceAccountUser, which is not supported in JSON based credentials. So you can

• 使用 P12 密钥
• 具有解决方法的用户 JSON 凭据:

制作凭证副本:

import static com.google.api.client.googleapis.util.Utils.getDefaultJsonFactory;
import static com.google.api.client.googleapis.util.Utils.getDefaultTransport;

private static final String APPLICATION_NAME = "AnyAppName";

private final List<String> SCOPES = ImmutableList.of(
        DirectoryScopes.ADMIN_DIRECTORY_GROUP_MEMBER, DirectoryScopes.ADMIN_DIRECTORY_USER, DirectoryScopes.ADMIN_DIRECTORY_GROUP);

private Directory service;

@PostConstruct
void init() throws GeneralSecurityException, IOException {
    GoogleCredential credential;
    try (InputStream is = new FileInputStream("./config/client_secret.json")) {
        credential = GoogleCredential.fromStream(is);
    }
    GoogleCredential credentialWithUser = new GoogleCredential.Builder()
            .setTransport(getDefaultTransport())
            .setJsonFactory(getDefaultJsonFactory())
            .setServiceAccountUser("[e-mail]")  // <--- mail of domain's admin
            .setServiceAccountId(credential.getServiceAccountId())
            .setServiceAccountScopes(SCOPES)
            .setServiceAccountPrivateKey(credential.getServiceAccountPrivateKey())
            .setServiceAccountPrivateKeyId(credential.getServiceAccountPrivateKeyId())
            .setTokenServerEncodedUrl(credential.getTokenServerEncodedUrl()).build();

    service = new Directory.Builder(getDefaultTransport(), getDefaultJsonFactory(), credentialWithUser).setApplicationName(APPLICATION_NAME).build();
}

 public void members() throws IOException {
    Members members = service.members().list("[e-mail]").execute();
    System.out.println(members);
 }

对于我的试用 G Suite 帐户，它有效！
