我正在使用apache2,python26,或多或少的最新版本的烧杯mod_wsgi

这是我的代码,我是从http://beaker.groovie.org/sessions.html#using获得的

from beaker.middleware import SessionMiddleware

def simple_app(environ, start_response):
    # Get the session object from the environ
    session = environ['beaker.session']

    # Check to see if a value is in the session
    if 'logged_in' in session:
        user = True
    else:
        user = False

    # Set some other session variable
    session['user_id'] = 10

    start_response('200 OK', [('Content-type', 'text/plain')])
    return ['User is logged in: %s' % user]

# Configure the SessionMiddleware
session_opts = {
    'session.type': 'file',
    'session.cookie_expires': True,
}
wsgi_app = SessionMiddleware(simple_app, session_opts)

当我转到localhost / beaker2.wsgi时,此方法工作正常.当我尝试两次更改时,站点失败：

1.
加

session.save()

要么

2.
更改

'session.type': 'cookie',

为什么在添加session.save()或将session.type更改为cookie时会出现错误？

完整的引用：
对不起日期和一切,用tail -f做到了

这是针对session.save()错误：

解决方法:

对于session.save()错误,它表示您没有通过设置data_dir会话缓存参数来告诉它保存在哪里

对于cookie错误,它需要一个秘密密钥validate_key设置,以便可以在将cookie发送到浏览器时对其进行编码,并在从浏览器获取cookie时对其进行解码和验证

为了解决它们,请使用您自己的值添加以下键：

对于文件：

session_opts['data_dir'] = "/some/place/to/save/"

饼干：

session_opts['validate_key'] = "some secret value"
session_opts['encrypt_key'] = "some other value"
