Google Drive 的读取超时问题

Question

我正在使用 Drive SDK v3 从驱动器上传/下载。授权是基于网页的 (OAuth2) 而不是 API 密钥，用户将在其中验证他们的谷歌帐户并授予所需的权限。最近，我从驱动器导出文档时遇到了读取超时问题。这是授权流程。

InputStream in = DriveUtils.class
            .getResourceAsStream("/client_secret.json");

    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(
            JSON_FACTORY, new InputStreamReader(in));

    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(DATA_STORE_FACTORY)
            .setAccessType("offline").build();

    Credential credential = new AuthorizationCodeInstalledApp(flow,
            new LocalServerReceiver()).authorize("user");
    System.out.println("Credentials saved to "
            + DATA_STORE_DIR.getAbsolutePath());
            
    Drive driveService = Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
            .setApplicationName(APPLICATION_NAME)
            .build();

我从 google-http-client 文档中找到了以下代码来手动设置请求超时。

Drive driveService = new Drive.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
            .setApplicationName(APPLICATION_NAME)
            .setHttpRequestInitializer(new HttpRequestInitializer() {

                @Override
                public void initialize(HttpRequest request) throws IOException {
                    request.setReadTimeout(5 * 60000); // 5 minutes
                }
            })
            .build();

当我使用它时，我收到以下错误。

{
  "code" : 403,
  "errors" : [ {
    "domain" : "usageLimits",
    "message" : "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
    "reason" : "dailyLimitExceededUnreg",
    "extendedHelp" : "https://code.google.com/apis/console"
  } ],
  "message" : "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
}

当我检查 API 控制台时，Drive API 未启用。但是如果我启用它，那么我需要使用基于 API 的身份验证。

但我需要保持基于用户的授权，但需要通过延长超时来解决超时问题。请帮忙

如果您打算将其用于单个用户，则应考虑使用服务帐户

HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
    GoogleCredential credential = GoogleCredential
        .fromStream(new FileInputStream(KEY_FILE_LOCATION))
        .createScoped(DriveScopes.all());

    // Construct the Analytics Reporting service object.
    return new Drive.Builder(httpTransport, JSON_FACTORY, credential)
        .setApplicationName(APPLICATION_NAME).build();
