Java 查询谷歌的目录API-错误：400错误请求

我试图通过Java库使用新的目录API从google的域中获取用户列表：“google-API-services-admin-Directory_v1-rev14-Java-1.17.0-rc”。在成功地进行身份验证并使用管理帐户获取令牌后，我尝试执行获取用户列表的查询，但得到错误400:Bad request

我使用的代码是：

GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
    .setAccessType("offline").setApprovalPrompt("force").setDataStoreFactory(oData).addRefreshListener(credentialRefreshListener).build();
String url = flow.newAuthorizationUrl().setRedirectUri(redirectURL).build();
System.out.println(url);
System.out.println("Enter Responsse Url");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
AuthorizationCodeResponseUrl authResponse = new AuthorizationCodeResponseUrl(br.readLine());

if (authResponse.getError() != null) {
    System.out.println("authorization denied...");// authorization denied...
} else {
    GoogleTokenResponse response = flow.newTokenRequest(authResponse.getCode()).setRedirectUri(redirectURL).execute();
    System.out.println("Access token: " + response.getAccessToken() + " Expire: " +
            response.getExpiresInSeconds());
    Credential credential = flow.createAndStoreCredential(response,"user");
    Credential credential1 = flow.loadCredential("user");
    Directory directory = new Directory.Builder(TRANSPORT, JSON_FACTORY, credential).setApplicationName("TestAPP/1.0").build();
    Directory.Users.List list = directory.users().list();
    Users users = list.execute();
    System.out.println(users.size());
}

接下来，您将找到此问题的日志：

有人想办法解决此问题吗？

使用列表时，需要指定域或客户。
