我是Google App Engine的新手。当我学习本教程时，我发现我们在php-mysql中所做的几件事在GAE中不可用。例如，在数据存储中，自动递增功能不可用。另外，我对GAE中的会话管理感到困惑。总而言之，我很困惑，无法想象整个事情。
请告诉我一个简单的用户管理系统，包括用户注册，用户登录，用户注销，会话（创建，管理，销毁）与数据存储。另外，请告诉我在哪里可以获得简单但有效的例子。
提前致谢。
我倾向于使用自己的用户和会话管理
对于我的Web处理程序，我将附加一个名为的装饰器和一个名为.装饰器将会话附加到每个请求，并且装饰器将确保用户已获得授权。sessionauthorizesessionauthorize
（需要注意的是，授权装饰器特定于我如何开发应用程序 - 用户名是大多数请求中的第一个参数）。
例如，Web处理程序可能看起来像这样：
class UserProfile(webapp.RequestHandler):
@session
@authorize
def get(self, user):
# Do some funky stuff
# The session is attached to the self object.
someObjectAttachedToSession = self.SessionObj.SomeStuff
self.response.out.write("hello %s" % user)
在上面的代码中，装饰器根据请求中存在的cookie附加了一些我需要的会话内容。标头将确保用户只能在会话正确的情况下访问该页面。sessionauthorize
装饰器代码如下：
import functools
from model import Session
import logging
def authorize(redirectTo = "/"):
def factory(method):
'Ensures that when an auth cookie is presented to the request that is is valid'
@functools.wraps(method)
def wrapper(self, *args, **kwargs):
#Get the session parameters
auth_id = self.request.cookies.get('auth_id', '')
session_id = self.request.cookies.get('session_id', '')
#Check the db for the session
session = Session.GetSession(session_id, auth_id)
if session is None:
self.redirect(redirectTo)
return
else:
if session.settings is None:
self.redirect(redirectTo)
return
username = session.settings.key().name()
if len(args) > 0:
if username != args[0]:
# The user is allowed to view this page.
self.redirect(redirectTo)
return
result = method(self, *args, **kwargs)
return result
return wrapper
return factory
def session(method):
'Ensures that the sessions object (if it exists) is attached to the request.'
@functools.wraps(method)
def wrapper(self, *args, **kwargs):
#Get the session parameters
auth_id = self.request.cookies.get('auth_id', '')
session_id = self.request.cookies.get('session_id', '')
#Check the db for the session
session = Session.GetSession(session_id, auth_id)
if session is None:
session = Session()
session.session_id = Session.MakeId()
session.auth_token = Session.MakeId()
session.put()
# Attach the session to the method
self.SessionObj = session
#Call the handler.
result = method(self, *args, **kwargs)
self.response.headers.add_header('Set-Cookie', 'auth_id=%s; path=/; HttpOnly' % str(session.auth_token))
self.response.headers.add_header('Set-Cookie', 'session_id=%s; path=/; HttpOnly' % str(session.session_id))
return result
return wrapper
def redirect(method, redirect = "/user/"):
'When a known user is logged in redirect them to their home page'
@functools.wraps(method)
def wrapper(self, *args, **kwargs):
try:
if self.SessionObj is not None:
if self.SessionObj.settings is not None:
# Check that the session is correct
username = self.SessionObj.settings.key().name()
self.redirect(redirect + username)
return
except:
pass
return method(self, *args, **kwargs)
return wrapper
