Question

我有一个从服务器收到的Google云端硬盘访问令牌。收到后，我尝试使用此令牌初始化GoogleCredential，然后对Drive API执行请求。但是当我尝试执行请求时，我会抓住下一个堆栈跟踪：

我如何初始化凭据并向云端硬盘执行请求：

private void initClient() {
    JsonFactory jsonFactory = JacksonFactory.getDefaultInstance();
    HttpTransport transport = AndroidHttp.newCompatibleTransport();
    try {
        GoogleClientSecrets googleClientSecrets = loadClientSecretsResource(mContext, jsonFactory);
        GoogleCredential credential = new GoogleCredential.Builder()
                .setClientSecrets(googleClientSecrets)
                .setJsonFactory(jsonFactory)
                .setTransport(transport)
                .build();
        credential.setAccessToken(AppPreferences.Storage.GoogleDrive.getToken(mContext));
        credential.refreshToken();
        mService = new Drive.Builder(transport, jsonFactory, credential)
                .setApplicationName(mContext.getResources().getString(R.string.app_name))
                .build();
        addCloud();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

private void addCloud() {
    Map<String, Long> quotaInfo = getQuotaInfo();
    CloudStorageCollector.saveCloudToDatabase(AppPreferences.Storage.GoogleDrive.getToken(mContext), BaseVault.VaultCode.GoogleDriveVault,
            quotaInfo.get(StoragesHelper.USED_QUOTA_KEY), quotaInfo.get(StoragesHelper.TOTAL_QUOTA_KEY));
}

public Map<String, Long> getQuotaInfo() {
    if (mService == null) return null;
    Map<String, Long> quotaInfo = new HashMap<>();
    try {
        About about = mService.about().get().execute();
        quotaInfo.put(StoragesHelper.USED_QUOTA_KEY, about.getQuotaBytesUsed());
        quotaInfo.put(StoragesHelper.TOTAL_QUOTA_KEY, about.getQuotaBytesTotal());
        return quotaInfo;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

在getQuotaInfo方法中，我捕获了异常。我做错了什么？

错误401: Invalid Credentials或无效的授权标头意味着您使用的访问令牌已过期或无效。

因此，尝试使用长期刷新令牌刷新访问令牌。如果失败，请尝试再次检查authorizing requests。以下是步骤：

创建应用程序时，请使用 Google Developers Console 进行注册。然后，Google会提供您稍后需要的信息，例如客户端ID和客户端密码。
在Google Developers Console中激活Drive API。（如果未在开发人员控制台中列出API，则跳过此步骤。）
当您的应用需要访问用户数据时，它会要求Google提供特定范围的访问权限。
Google向用户显示同意屏幕，要求他们授权您的应用程序请求他们的部分数据。
如果用户批准，那么Google会为您的应用提供一个短期访问令牌。
您的应用程序请求用户数据，将访问令牌附加到请求中。
如果Google确定您的请求和令牌有效，则会返回请求的数据。

某些流程包含其他步骤，例如使用刷新令牌来获取新的访问令牌。有关各种类型应用程序的流的详细信息，请参阅Google's OAuth 2.0 documentation。
