我遇到谷歌推送通知(驱动器)的问题.我使用的服务帐户非常适用于所有其他驱动器操作,除了驱动器更改监视.

以下是现在因"未授权的WebHook回调通道"异常而失败的应用程序代码.我还转储了调用drive.changes.watch.execute时生成的请求和响应.

目标通知地址在API和auth推送控制面板中列入白名单(我甚至​​将其列在Javascript起源和引用中),现在我遇到了这个401 Unauthorized错误.

有人知道我在哪里弄错了吗？谢谢你的帮助.

PrivateKey serviceAccountPrivateKey = SecurityUtils.loadPrivateKeyFromKeyStore(SecurityUtils.getPkcs12KeyStore(), p12File, "notasecret", "privatekey", "notasecret");
JsonFactory jsonFactory = new JacksonFactory();
HttpTransport t = GoogleNetHttpTransport.newTrustedTransport();
GoogleCredential gc = new GoogleCredential.Builder()
                .setTransport(t)
                .setJsonFactory(jsonFactory)
                .setServiceAccountScopes(Collections.singleton(DriveScopes.DRIVE))
                .setServiceAccountPrivateKey(serviceAccountPrivateKey)
                .setServiceAccountId(Config.SERVICE_ACCOUNT_ID)
                .setServiceAccountUser(Config.SERVICE_ACCOUNT_USER)
                .build();

drive = new Drive.Builder(t, jsonFactory, null).setHttpRequestInitializer(gc).setApplicationName(cfg.getStringParam(Config.GAE_APPLICATION_NAME)).build();

// THIS WORKS
Changes.List request = drive.changes().list();
ChangeList changes = request.execute();

// THIS DOES NOT WORK
Channel channel = new Channel();
channel.setId(UUID.randomUUID().toString());
channel.setType("web_hook");
channel.setAddress(Config.PUSH_NOTIFICATION_ADDRESS);
Channel c = drive.changes().watch(channel).execute();
