Drive SDK获取文件夹大小 [英] Drive SDK Get Folder Size

问题描述

我使用'quotaBytedUsed'属性，同时使用授权get获取文件请求 - Files.list 。

我将获得的长整型值转换为KB / MB / Gb的文件大小。

然而，所有文件夹的大小都是1 KB 。此值并不反映文件夹中所有内容大小的总和。

如何获得这笔金额（如果可能，不需要额外的服务器请求） ？

用于将'quotaBytesUsed'转换为文件大小的代码是

  private string [] SizeSuffixes = new [] {B，KB，MB，GB，TB}; 
 
 private string SizeConvert（long？fileSize）
 {
 if（！fileSize.HasValue）
 return; 
 
 var size = fileSize.Value; 
 
 if（size< = 1024）
 {
 return1 KB; 
} 
 
 var suffixIndex = 0; 
 
 while（size&> 1024）
 {
 size = size / 1024; 
 
 suffixIndex ++; 
} 
 
 return size.ToString（CultureInfo.InvariantCulture.NumberFormat）++ SizeSuffixes [suffixIndex]; 
 
  

解决方案

该文件夹对象，而不是其内容。
api不支持获取文件夹内容的大小。

鉴于相同的文件/文件夹可以放在多个文件夹中，我怀疑它会被支持。

您需要递归计算它，例如使用appengine任务队列。

I am using 'quotaBytedUsed' property while getting Files using an authorized get request - Files.list.

I am converting the long value obtained to file size in KB/MB/Gb as appropriate.

However, size of all folders obtained is 1 KB. This value doesn't reflect the sum total of sizes of all content in the folder.

How can I get the this sum ( if possible without any extra request to server )?

Code used for converting 'quotaBytesUsed' to file size is

private string[] SizeSuffixes = new[] { "B", "KB", "MB", "GB", "TB" };

private string SizeConvert(long? fileSize)
    {
        if (!fileSize.HasValue)
            return "";

        var size = fileSize.Value;

        if (size <= 1024)
        {
            return "1 KB";
        }

        var suffixIndex = 0;

        while (size > 1024)
        {
            size = size / 1024;

            suffixIndex++;
        }

        return size.ToString(CultureInfo.InvariantCulture.NumberFormat) + " " + SizeSuffixes[suffixIndex];
    }

解决方案

You are getting the size of the folder object, not its contents. The api doesnt support getting a folder content's size.

Given that the same file/folder can be in multiple folders, I doubt it will ever be supported.

You need to recursively calculate it, using appengine task queues for example.
