如何部分下载谷歌驱动器文件？ [英] How to partially download google drive files?

问题描述

我试图从谷歌驱动器下载文件的特定字节。当我设置字节= 0-1000时，它工作正常。当我指定特定范围的字节时（如下所示），下载的视频大小是正确的，但我无法播放视频。

  HttpRequest httpRequestGet = drive.getRequestFactory（）。buildGetRequest（new GenericUrl（url.toString（）））; 
 httpRequestGet.getHeaders（）。setRange（bytes =+ 10000 + - + 200000）; 
  

我错过了什么吗？这可能是因为通过在文件的下方指定一个字节范围，您可以跳过整个头文件，导致只是一个乱码的数据块。

I am trying to download specific bytes of a file from google drive. When I set bytes=0-1000, it works fine. When I am specifying a particular range of bytes (as shown below), the size of the video getting downloaded is correct but, I couldn't play the video.

HttpRequest httpRequestGet = drive.getRequestFactory().buildGetRequest(new GenericUrl(url.toString()));
httpRequestGet.getHeaders().setRange("bytes=" + 10000 + "-" + 200000);

Am I missing something? Thanks in advance.

解决方案

It could be probably because by specifying a byte range further down in the file you are skipping the entire header of the file, which results in just a garbled block of data.
