使用python api递归计算每个Dropbox文件夹大小

EDIT: I want to calculate each folder size not just entire dropbox size... My code is working fine for whole dropbox size

编辑：我想计算每个文件夹大小而不仅仅是整个保管箱大小...我的代码适用于整个保管箱大小

I am having difficulty in calculating each folder size of dropbox using python api as dropbox returns folder size as zero

我很难使用python api计算dropbox的每个文件夹大小，因为dropbox将文件夹大小返回为零

here's my code so far but it's giving me wrong answer

这是我的代码到目前为止，但它给了我错误的答案

  def main(dp_path):
   a=  client.metadata(dp_path)
   size_local = 0
   for x in a['contents']:
     if x['is_dir']==False:
       global size
       size += int(x['bytes'])
       size_local += int(x['bytes'])

       #print "Total size so far :"+str(size/(1024.00*1024.00))+" Mb..." 


     if x['is_dir']==True:
       a = main(str(x['path']))
       print str(x['path'])+" size=="+str(a/(1024.00*1024.00))+" Mb..."

     return size_local+size


 if __name__ == '__main__':
   global size
   size=0
   main('/')
   print str(size/(1024.00*1024.00))+" Mb"

EDIT 2: It seems I misunderstood the question. Here's code that prints out the sizes of each folder (in order of decreasing size):

编辑2：我似乎误解了这个问题。这里的代码打印出每个文件夹的大小（按大小减小的顺序）：

from dropbox.client import DropboxClient
from collections import defaultdict

client = DropboxClient('<YOUR ACCESS TOKEN>')

sizes = {}
cursor = None
while cursor is None or result['has_more']:
    result = client.delta(cursor)
    for path, metadata in result['entries']:
        sizes[path] = metadata['bytes'] if metadata else 0
    cursor = result['cursor']

foldersizes = defaultdict(lambda: 0)
for path, size in sizes.items():
    segments = path.split('/')
    for i in range(1, len(segments)):
        folder = '/'.join(segments[:i])
        if folder == '': folder = '/'
        foldersizes[folder] += size

for folder in reversed(sorted(foldersizes.keys(), key=lambda x: foldersizes[x])):
    print '%s: %d' % (folder, foldersizes[folder])

EDIT: I had a major bug in the second code snippet (the delta one), and I've now tested all three and found them all to report the same number.

编辑：我在第二个代码片段（delta delta）中有一个主要错误，我现在已经测试了所有三个并发现它们全部报告相同的数字。

This works:

这有效：

from dropbox.client import DropboxClient

client = DropboxClient('<YOUR ACCESS TOKEN>')

def size(path):
    return sum(
        f['bytes'] if not f['is_dir'] else size(f['path'])
        for f in client.metadata(path)['contents']
    )

print size('/')

But it's much more efficient to use /delta:

但使用/ delta效率更高：

sizes = {}
cursor = None
while cursor is None or result['has_more']:
    result = client.delta(cursor)
    for path, metadata in result['entries']:
        sizes[path] = metadata['bytes'] if metadata else 0
    cursor = result['cursor']

print sum(sizes.values())

And if you truly just need to know the overall usage for the account, you can just do this:

如果您真的需要知道帐户的整体使用情况，您可以这样做：

quota_info = client.account_info()['quota_info']
print quota_info['normal'] + quota_info['shared']
