这段时间一直想尝试着在SAE中使用Python，初步选择了Web.py框架做为开发框架，但是可怜SAE上的资料少的可怜，有点问题基本上解决不了，今天解决一个Session在Session的存储问题,在SAE中不能直接用本地文件存储，好像是权限的原因，我现在采用的是保存在mysql中，效果也不错。希望对大家有帮助。直接上代码了。

#是否具有调试功能
web.config.debug = False
# app = web.application(urls, globals()).wsgifunc()
# application = sae.create_wsgi_app(app)
 
#解决Session在SAE中的问题
app = web.application(urls, globals())
 
#将session保存在数据库中
db = settings.db
store = web.session.DBStore(db, \'sessions\')
#session = web.session.Session(app, store, initializer={\'access_token\': \'true\'})
session = web.session.Session(app, store)
web.config._session = session
 
application = sae.create_wsgi_app(app.wsgifunc())
