问题描述

我正在尝试使用适用于python的pydrive模块自动从Google驱动器下载一个简单的文本文件.我不断收到以下错误:

I am trying to download a simple text file from google drive automatically with the pydrive module for python. I keep getting the following error:

有什么建议吗?

import pydrive
from pydrive.drive import GoogleDrive

from pydrive.auth import GoogleAuth

gauth = GoogleAuth()
gauth.LoadCredentialsFile(r"C:\Users\XXXXX\.credentials\drive-python-quickstart.json")
drive = GoogleDrive(gauth)

print "Auth Success"

folder_id = '0BxbuUXtrs7adSFFYMG0zS3VZNFE'
lister = drive.ListFile({'q': "'%s' in parents" % folder_id}).GetList()
for item in lister:
    print item['title']
    item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' +    item['title'])

推荐答案

您可能正在尝试下载google文档，电子表格或其他非普通文件.

You are possibly trying to download a google document, spreadsheet or whatever else which is not a ordinary file.

不久前，当我尝试下载mimeType文件:application/vnd.google-apps.document时，出现了完全相同的错误.在下载之前，文档必须导出为其他格式. 检查以下内容:

I got exactly the same error a few moments ago, when I tried to download a file of mimeType: application/vnd.google-apps.document. The document has to be exported to other format before downloading. Check this:

import pydrive
from pydrive.drive import GoogleDrive

from pydrive.auth import GoogleAuth

gauth = GoogleAuth()
gauth.LoadCredentialsFile(r"C:\Users\XXXXX\.credentials\drive-python-    quickstart.json")
drive = GoogleDrive(gauth)

print "Auth Success"

folder_id = '0BxbuUXtrs7adSFFYMG0zS3VZNFE'
lister = drive.ListFile({'q': "'%s' in parents" % folder_id}).GetList()
for item in lister:
    print(item['title'])
    # this should tell you which mimetype the file you're trying to download 
    # has. 
    print('title: %s, mimeType: %s' % (item['title'], item['mimeType']))
    mimetypes = {
        # Drive Document files as PDF
        'application/vnd.google-apps.document': 'application/pdf',

        # Drive Sheets files as MS Excel files.
        'application/vnd.google-apps.spreadsheet': 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'

    # see https://developers.google.com/drive/v3/web/mime-types
    }
    download_mimetype = None
    if file['mimeType'] in mimetypes:
        download_mimetype = mimetypes[file['mimeType']]
        file.GetContentFile(file['title'], mimetype=download_mimetype)

        item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' + item['title'], mimetype=download_mimetype)
    else: 
        item.GetContentFile(r'C:\Users\XXXXX\Desktop\googedrive\\' + item['title'])

这应该有效.
