使用Artifactory REST API获取文件夹大小。以下是示例代码：

import requests
import json

username = 'username'
password = 'password'
base_url = 'https://your.artifactory.url/artifactory'

def get_folder_size(path):
  '''
  Get size of a folder in Artifactory
  '''
  headers = {'Content-Type': 'application/json'}
  url = '{}/api/storage/{}/?list&deep=1'.format(base_url, path)
  response = requests.get(url, headers=headers, auth=(username, password))
  data = json.loads(response.content.decode('utf-8'))
  
  # loop through all items and sum their size
  size = 0
  for item in data['children']:
    size += item['size']
    
  return size

使用方法：

folder_size = get_folder_size('path/to/folder')
print('Folder size: {} bytes'.format(folder_size))
