Question

这是我的脚本（从别人那里砍掉），用于从Google云端硬盘下载文件。但是，当我下载文件时，我的本地驱动器上的文件的创建/修改日期始终是运行脚本并处理该文件的时间。为了有用，我需要能够保留文件在谷歌驱动器上显示的日期，例如：

是否有更改下载脚本以便在将文件下载到我的驱动器时保持文件的日期不变？这是API参考，我无法找到答案：

这是剧本：

from __future__ import print_function
import sys, httplib2, os, datetime, io
from time import gmtime, strftime
from apiclient import discovery

from oauth2client import client
from oauth2client import tools

try:

    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None

def get_credentials():
    home_dir = os.path.expanduser('~')
    credential_dir = os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):
        os.makedirs(credential_dir)

        return True
    return False

def downloadFile(file_name, file_id, mimeType, service):
    request = service.files().get_media(fileId=file_id)
    if "application/vnd.google-apps" in mimeType:
        if "document" in mimeType:
            request = service.files().export_media(fileId=file_id, mimeType='application/vnd.openxmlformats-officedocument.wordprocessingml.document')

        else:

            file_name = file_name + ".pdf"
    print("Downloading -- " + file_name)
    response = request.execute()
    with open(os.path.join(OUTPUT_DIR, file_name), "wb") as wer:
        wer.write(response)

def listFiles(service):
    def getPage(pageTok):
        return service.files().list(q="mimeType != 'application/vnd.google-apps.folder'",
               pageSize=1000, pageToken=pageTok, fields="nextPageToken,files(id,name,mimeType)").execute()
    pT = ''; files=[]
    while pT is not None:
        results = getPage(pT)
        pT = results.get('nextPageToken')
        files = files + results.get('files', [])
    return files

def main():
        credentials = get_credentials()
        http = credentials.authorize(httplib2.Http())
        service = discovery.build('drive', 'v3', http=http)
        for item in listFiles(service):
            downloadFile(item.get('name'), item.get('id'), item.get('mimeType'), service)

if __name__ == '__main__':
    main()

我能做的最好的事情就是在这里添加创建者：

downloadFile(item.get('name'), item.get('id'), item.get('mimeType'), item.get('createdDate'), service)

我真的建议你使用gdcp: Google Drive cp。

您需要拥有的只是：

Python2.7
PIP

然后你需要安装这些依赖项：

$ pip install pydrive
$ pip install backoff

最后，按照setup procedure将GDrive帐户与gdcp相关联，然后从GDrive帐户上传/下载

通过Python从Google云端硬盘备份文件
