【问题描述】：

我正在尝试将电子表格文件从我的驱动器下载到我的计算机。我能够进行身份验证、获取文件列表甚至成功获取元数据。但是当我尝试下载文件时，出现以下错误：

downloading file starts
An error occurred: <HttpError 400 when requesting https://www.googleapis.com/dri
ve/v2/files/1vJetI_p8YEYiKvPVl0LtXGS5uIAx1eRGUupsXoh7UbI?alt=media returned "The
 specified file does not support the requested alternate representation.">
downloading file ends

我在 SO 上找不到任何此类问题或问题，并且 SO 上提供的用于下载电子表格的其他方法或解决方案已过时。Google 已弃用这些方法或解决方案。

这是代码，我用来下载文件：

import httplib2
import os    
from apiclient import discovery
import oauth2client
from oauth2client import client
from oauth2client import tools


from apiclient import errors
from apiclient import http

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

#SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'
SCOPES = 'https://www.googleapis.com/auth/drive'
CLIENT_SECRET_FILE = 'client_secrets.json'
APPLICATION_NAME = 'Drive API Quickstart'


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)
    credential_path = os.path.join(credential_dir,
                                   'drive-quickstart.json')

    store = oauth2client.file.Storage(credential_path)
    credentials = store.get()

    if not credentials or credentials.invalid:
        flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent = APPLICATION_NAME
        if flags:
            credentials = tools.run_flow(flow, store, flags)
        else: # Needed only for compatability with Python 2.6
            credentials = tools.run(flow, store)
        print 'Storing credentials to ' + credential_path
    return credentials

def main():
    credentials = get_credentials()
    http = credentials.authorize(httplib2.Http())
    service = discovery.build('drive', 'v2', http=http)

    file_id = '1vJetI_p8YEYiKvPVl0LtXGS5uIAx1eRGUupsXoh7UbI'

    print "downloading file starts"
    download_file(service, file_id)
    print "downloading file ends "

def download_file(service, file_id):

    local_fd = open("foo.csv", "w+")
    request = service.files().get_media(fileId=file_id)
    media_request = http.MediaIoBaseDownload(local_fd, request)

    while True:
        try:
            download_progress, done = media_request.next_chunk()
        except errors.HttpError, error:
            print 'An error occurred: %s' % error
            return
        if download_progress:
            print 'Download Progress: %d%%' % int(download_progress.progress() * 100)
        if done:
            print 'Download Complete'
            return

if __name__ == '__main__':
    main()

【解决方案1】：

Google 电子表格没有媒体。相反，他们有 exportLinks。获取文件元数据，然后查看导出链接并选择合适的 URL。

【讨论】：

我收到以下元数据，但没有导出链接或下载链接 { 'selfLink': 'parentLink': 'iconLink': 'embedLink': 'alternateLink': 'selfLink': 'selfLink': }
粘贴您在 files.get Try-It 中看到的元数据，以便我们查看

【解决方案2】：

这段代码对我有用。我只需要从谷歌开发者仪表板下载 client_secret.json 并保存在与 python 脚本相同的目录中。

在 list_of_lists 变量中，我得到了一个列表，其中每一行都是列表。

import gspread
import json
from oauth2client.client import SignedJwtAssertionCredentials


json_key = json.load(open('client_secret.json'))
scope = ['https://spreadsheets.google.com/feeds']
credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)

gc = gspread.authorize(credentials)
sht1 = gc.open_by_key('<id_of_sheet>')
worksheet_list = sht1.worksheets()
worksheet = sht1.sheet1
list_of_lists = worksheet.get_all_values()

for row in list_of_lists :
    print row
