仅在不存在python的情况下,如何才能在Google驱动器中创建新文件夹? 我对这个Google API和python完全陌生。
(我有我帐户的访问令牌,我想使用该令牌创建文件夹。)
创建文件夹
import json
import requests
headers = {"Authorization": "Bearer Token"}
data = {
"name": "name",
"mimeType": "application/vnd.google-apps.folder"
}
r = requests.post("https://www.googleapis.com/drive/v3/files",
headers=headers,data = data)
print(r.text)
仅创建文件,而不创建文件夹。我该如何解决该问题?

def get_folder_id(self, folder, parent):
_r = None
try:
url = 'https://www.googleapis.com/drive/v3/files?q={0}'. \
format(quote(
"mimeType='application/vnd.google-apps.folder'"
" and name ='{0}'"
" and trashed != true"
" and '{1}' in parents".format(folder, parent),
safe='~()*!.\''
)
)
_r = requests.get(url, headers={
"Authorization": "Bearer {0}".format(self.get_access_token()),
"Content-Type": self.file_bean.get_content_type(),
})
_r.raise_for_status()
_dict = _r.json()
if 'files' in _dict and len(_dict['files']):
return _dict['files'][0]['id']
else:
_f = self.create_folder(folder, parent)
if _f:
return _f
status, status_message = self.get_invalid_folder()
except requests.exceptions.HTTPError:
status, status_message = self.get_http_error(_r)
except Exception as e:
logger.exception(e)
status, status_message = self.get_unknown_error()
def create_folder(self, folder_name, parent_folder_id):
url = 'https://www.googleapis.com/drive/v3/files'
headers = {
'Authorization': 'Bearer {}'.format(self.get_access_token()), # get your access token
'Content-Type': 'application/json'
}
metadata = {
'name': folder_name, #folder_name as a string
'parents': [parent_folder_id], # parent folder id (="root" if you want to create a folder in root)
'mimeType': 'application/vnd.google-apps.folder'
}
response = requests.post(url, headers=headers, data=json.dumps(metadata))
response = response.json()
if 'error' not in response:
return response['id'] # finally return folder id
使用get_folder_id在内部创建文件夹(如果不存在)。

您的第一步是定义“仅当不存在时”的含义。在Google云端硬盘中,文件(而文件夹只是具有特殊mime类型的文件)由ID标识,不由文件名标识。因此,我可以有很多文件夹,而且都具有相同的名称。
我将假设“仅当它不存在时”才真正意味着“仅当具有给定名称的文件夹不存在时”。步骤是:-
name=foldername, trashed=false, mime-type=application/vnd.google-apps.folder
执行文件/列表。确保您的files.list正确处理nextPageToken
If the count of results == 0, files.create foldername
