如何用Python从本地将一个文件备份到Google Drive

1、要有一个Google App账号：

这个可以上网上去申请，申请地址为：https://developers.google.com/appengine/?hl=zh-cn

2、创建一个Google App应用：

然后注到https://appengine.google.com/创建一个应用，创建应用时要选择本地应用，scope选择https://www.googleapis.com/auth/drive

3、创建应用成功以后到https://code.google.com/apis/console/查看你的应用的信息，点击API Access，将client id，client secret，redirect uri记录下来，

下面就是测试代码，

#coding=utf-8
import httplib2
import pprint

from apiclient.discovery import build
from apiclient.http import MediaFileUpload
from oauth2client.client import OAuth2WebServerFlow

# Copy your credentials from the APIs Console
CLIENT_ID = '573720769345-559h9541b7at50esq6asbhf4ok5oflon.apps.googleusercontent.com'
CLIENT_SECRET = 'hdNHj26F0ZGWGshHf3B42UuN'

# Check https://developers.google.com/drive/scopes for all available scopes
OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'

# Redirect URI for installed apps
REDIRECT_URI = 'urn:ietf:wg:oauth:2.0:oob'

# Path to the file to upload
FILENAME = 'document.txt'

# Run through the OAuth flow and retrieve credentials
flow = OAuth2WebServerFlow(CLIENT_ID, CLIENT_SECRET, OAUTH_SCOPE, REDIRECT_URI)
authorize_url = flow.step1_get_authorize_url()
print 'Go to the following link in your browser: ' + authorize_url
code = raw_input('Enter verification code: ').strip()
credentials = flow.step2_exchange(code)

# Create an httplib2.Http object and authorize it with our credentials
http = httplib2.Http()
http = credentials.authorize(http)

drive_service = build('drive', 'v2', http=http)

# Insert a file
media_body = MediaFileUpload(FILENAME, mimetype='text/plain', resumable=True)
body = {
  'title': 'My Documents',
  'description': 'A test document',
  'mimeType': 'text/plain'
}

file = drive_service.files().insert(body=body, media_body=media_body).execute()
pprint.pprint(file)

运行代码后会给你一个地址，将地址复制到浏览器的地址栏里，加载出页面后点击accept，会给你一个字符串，复制下来，

输入到后台，回车等待后台显示大批代码后表名文件上传成功。

如果有部分人上传不成功，可以使用VPN进行翻墙，剩下的就不多说了。
