Google Sites API + OAuth2（在Appengine上） [英] Google Sites API + OAuth2 (on Appengine)

问题描述

我一直在尝试使用Python库来访问Google Sites API。

第一步需要用户授权我们的应用程序，他们推荐使用OAuth2，他们提供了一个可以找到的库 here 。

授权过程最终以OAuth2Credentials对象结束。

问题是，当我尝试向Google Sites API发出请求时，假设我这样做：

  import gdata.sites.client 
 client = gdata.sites.client.SitesClient（site = None，domain ='mydomain.com'）
  
 我不知道如何使用OAuth2Credentials对象。
解决方案
我花了好几个小时试图做到这一点，最终在这篇博文中找到了答案：

下面是一个结合使用oauth2client和gdata API的例子访问包括'Monkey Patching'在内的Google协作平台：
从oauth2client.client获取
 
 
 从oauth2client.file导入flow_from_clientsecrets 
 import存储
 from oauth2client.tools import run 
 import gdata.sites.client 
 import gdata.sites.data 
 
 SCOPE ='https://sites.google.com/feeds/ '
 
＃client_secrets.json是从API控制台下载的：
＃https://code.google.com/apis/console/#project:<PROJECT_ID>:access 
＃where< PROJECT_ID>是你项目的ID 
 
 flow = flow_from_clientsecrets（'client_secrets.json'，$ b $ scope = SCOPE，
 redirect_uri ='http：// localhost'）
 
 storage = Storage（'plus.dat'）
 credentials = storage.get（）
 $ b如果凭证是None或credentials.invalid：
 credentials = run（流量，存储）
 
＃'Monkey Patch'凭据中的数据转换为gdata OAuth2Token 
＃这是基于此博客文章中的信息：
＃https：// groups.google.com/forum/m/#!msg/google-apps-developer-blog/1pGRCivuSUI/3EAIioKp0-wJ 
 
 auth2token = gdata.gauth.OAuth2Token（client_id = credentials.client_id，
 client_secret = credentials.client_secret，$ b $ scope = SCOPE，
 access_token = credentials.access_token，
 refresh_token = credentials.refresh_token，
 user_agent ='sites-test / 1.0' ）
 
＃创建一个gdata客户端
 
 client = gdata.sites.client.SitesClie nt（source ='sites-test'，
 site ='YOUR.SITE'，
 domain ='YOUR.DOMAIN'，
 auth_token = auth2token）
 
 ＃授权
 
 auth2token.authorize（客户端）
 
＃调用API在feed.entry中输入网站内容Feed 
 
 feed = client.GetContentFeed（）
 
：
 print'％s [％s]'％ （entry.title.text，entry.Kind（））
  
 
I've been trying to make use of the Python Library to access the Google Sites API. 

The first step requires a user to authorize our application, they recommend to use OAuth2 and they provide a library that can be found here.

At the end of the authorization process you end up with an OAuth2Credentials object. 

The problem is, when I try to make requests to the Google Sites API, let's say I do:
import gdata.sites.client
client = gdata.sites.client.SitesClient(site=None, domain='mydomain.com')
I don't know how to make use of the OAuth2Credentials object.
解决方案
I spent quite a few hours trying to do exactly this and finally found the answer in this blog post:

Here is a soup to nuts example of using the oauth2client together with the gdata API to access Google Sites including the 'Monkey Patching':
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run
import gdata.sites.client
import gdata.sites.data

SCOPE = 'https://sites.google.com/feeds/'

# client_secrets.json is downloaded from the API console:
# https://code.google.com/apis/console/#project:<PROJECT_ID>:access
# where <PROJECT_ID> is the ID of your project

flow = flow_from_clientsecrets('client_secrets.json',
                               scope=SCOPE,
                               redirect_uri='http://localhost')

storage = Storage('plus.dat')
credentials = storage.get()

if credentials is None or credentials.invalid:
    credentials = run(flow, storage)

# 'Monkey Patch' the data in the credentials into a gdata OAuth2Token
# This is based on information in this blog post:
# https://groups.google.com/forum/m/#!msg/google-apps-developer-blog/1pGRCivuSUI/3EAIioKp0-wJ

auth2token = gdata.gauth.OAuth2Token(client_id=credentials.client_id,
  client_secret=credentials.client_secret,
  scope=SCOPE,
  access_token=credentials.access_token,
  refresh_token=credentials.refresh_token,
  user_agent='sites-test/1.0')

# Create a gdata client

client = gdata.sites.client.SitesClient(source='sites-test',
                                        site='YOUR.SITE',
                                        domain='YOUR.DOMAIN',
                                        auth_token=auth2token)

# Authorize it

auth2token.authorize(client)

# Call an API e.g. to get the site content feed

feed = client.GetContentFeed()

for entry in feed.entry:
    print '%s [%s]' % (entry.title.text, entry.Kind())
