Question

尝试下载文件时收到错误，我无法从云端硬盘下载文件。

这是我使用的代码

private static InputStream downloadFile(String token, File file) {
Drive service = getDriveService(getCredential(token));

if (file.getDownloadUrl() != null && file.getDownloadUrl().length() > 0) {
  try {
    HttpResponse resp =
        service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl()))
            .execute();
    return resp.getContent();
  } catch (IOException e) {
    // An error occurred.
    e.printStackTrace();
    return null;
  }
} else {
  // The file doesn't have any content stored on Drive.
  return null;
}

}

我收到此错误

我在其他请求中测试令牌并且它是否有效，所以不知道为什么当我尝试下载文件时显示401错误。

Answer 1

我在使用PHP库时遇到了类似的问题 - 事实证明您需要通过身份验证提出请求 - 401错误意味着您未经过身份验证。
