Question

我使用此代码从文件ID下载Google驱动器文件，并为其提供一个文件名

!pip install -U -q PyDrive

from google.colab import files
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials
import os
import sys


auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

def downloadFiles(googleID, fileName):
    print("Downloading ", fileName)
    toDl = drive.CreateFile({'id': googleID})
    toDl.GetContentFile(fileName)

downloadFiles("0B7Mdz82xyAxcMzJYOFhfg5gfMnp6Tl9Cei00U3BKTGNN","news.npy")

downloadFiles中第一个参数的数字字符串是google驱动器文件ID，可通过右键单击文件并选择“获取共享”链接获得。

我尝试使用Google驱动器文件夹的共享链接ID进行操作，这是我得到的错误

downloadFiles("1kdNDfvg2zyyXYYrcXVnuuhIOnSLgtrnE","dlFolder")

!pip install -U -q PyDrive
import os
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials

# 1. Authenticate and create the PyDrive client.
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

# choose a local (colab) directory to store the data.
local_download_path = ''
try:
    os.makedirs(local_download_path)
except: pass

# 2. Auto-iterate using the query syntax
#    https://developers.google.com/drive/v2/web/search-parameters
file_list = drive.ListFile(
    {'q': "'1m4t_k5N7-W3saafdfddfdWCqfc1D0xHmc20r' in parents"}).GetList()  #use your own folder ID here

for f in file_list:
    # 3. Create & download by id.
    print('title: %s, id: %s' % (f['title'], f['id']))
    fname = f['title']
    print('downloading to {}'.format(fname))
    f_ = drive.CreateFile({'id': f['id']})
    f_.GetContentFile(fname)
