解決web.py在SAE雲中的Session使用問題

這段時間一直想嘗試着在SAE中使用Python，初步選擇了Web.py框架做為開發框架，但是可憐SAE上的資料少的可憐，有點問題基本上解決不了，今天解決一個Session在Session的存儲問題,在SAE中不能直接用本地文件存儲，好像是權限的原因，我現在采用的是保存在mysql中，效果也不錯。希望對大家有幫助。直接上代碼了。

index.wsgi

#!/usr/bin/env python
# coding: utf-8
import os
import web
import sae
from config.url import urls
from config import settings

#是否具有調試功能
web.config.debug = False
# app = web.application(urls, globals()).wsgifunc()
# application = sae.create_wsgi_app(app)

#解決Session在SAE中的問題
app = web.application(urls, globals())

#將session保存在數據庫中
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())

url.py

#!/usr/bin/env python
# coding: utf-8

pre_fix = 'controllers.'

urls = (
    '/',                    pre_fix + 'todo.Index',
    '/todo/new',            pre_fix + 'todo.New',
    '/todo/(\d+)',          pre_fix + 'todo.View',
    '/todo/(\d+)/edit',     pre_fix + 'todo.Edit',
    '/todo/(\d+)/delete',   pre_fix + 'todo.Delete',
    '/todo/(\d+)/finish',   pre_fix + 'todo.Finish',
    '/todo/login', pre_fix + 'login.LoginUser',
    '/todo/checkuser',pre_fix+'login.CheckUser',
    '/todo/reset',pre_fix+'todo.reset',
    '/todo/saveupload','mycontrollers.saveupload.SaveUpload'

        #獲取Session相關信息
        myloadhook()
        #獲取表單信息
        i = web.input()
        username =i.get('txtUserName',None)
        password=i.get('txtUserPass',None)
        #從全局配置文件中得到session
        session = web.config._session
        if username == 'chu888' and password == 'chu888':
            session.access_token = 'true'
            raise web.seeother('/')
        else:
            session.access_token = 'false'
            raise web.seeother('/todo/login')
