我有一个应用引擎应用程序,我在其上标记我的每月费用以及一些评论或理由。我想将这些数据导出到 Google云端硬盘电子表格。我使用Django框架。
我已经阅读了Google here提供的教程。 但他们使用webapp2和jinja实现了它。此外,Implementing Using Django的文档似乎过于陈旧,因为我不使用Django ORM。
以下是我用来上传的代码示例。如果下面粘贴的东西是垃圾,我非常抱歉。请帮忙。
from django.utils.datastructures import SortedDict
import os
from apiclient.discovery import build
from apiclient.http import MediaFileUpload
from oauth2client.appengine import OAuth2DecoratorFromClientSecrets
decorator = OAuth2DecoratorFromClientSecrets(os.path.join(os.path.dirname(__file__ ), 'clientSecrets.json'), 'https://www.googleapis.com/auth/drive')
drive_service = build('drive', 'v2')
class Exporter(object):
serializedObjects = []
mime_type = 'text/plain'
fileToExport = None
request = None
def __init__(self, serializedObjects, request):
self.serializedObjects = serializedObjects
self.request = request
def createCSV(self):
import csv
import StringIO
stdout = StringIO.StringIO()
writer = csv.writer(stdout)
for obj in self.serializedObjects:
for value in obj.values():
writer.writerow([value])
# I will get the csv produced from my datastore objects here.
# I would like to upload this into a Google Spreadsheet.
# The child class ExportToSpreadSheet tries to do this.
return stdout.getvalue()
class ExportToSpreadSheet(Exporter):
def __init__(self, *args, **kwargs):
super(ExportToSpreadSheet, self).__init__(*args, **kwargs)
self.mime_type = 'application/vnd.google-apps.spreadsheet'
def create(self):
import datetime
valueToDrive = self.createCSV()
media_body = MediaFileUpload(valueToDrive, mimetype=self.mime_type, resumable=True)
body = {
'title' : 'MyExpense_%s' % datetime.datetime.now().strftime('%d_%b_%Y_%H_%M_%S'),
'description' : '',
'mimeType' : self.mime_type
}
self.fileToExport = drive_service.files().insert(body=body, media_body=media_body, convert=True)
return self.fileToExport
@decorator.oauth_aware
def upload(self):
if decorator.has_credentials():
self.create()
self.fileToExport.execute(decorator.http())
return self.fileToExport
raise Exception('user does not have the credentials to upload to google drive.')
@ decorator.oauth_aware 仅适用于webapp.RequestHandler子类。为什么我这么说是因为我在运行代码时遇到了这个错误。

由于我使用的是Django框架,因此我无法获得Request处理程序。
如何在我的场景中集成或执行此操作?我非常感谢我可能错过的任何代码示例或相关链接。
此外,整个事情发生在ajax调用中。
提前致谢。

使用mimeType=text/csv
并在上传过程中,请求从csv转换为电子表格:
drive_service.files().insert(covert=True, body=body, media_body=media_body, convert=True)
