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

这是我的代码，我从http://beaker.groovie.org/sessions.html#using

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，这工作正常。当我尝试两项更改时，网站失败：

1.添加

session.save()

或者

2.改变

'session.type': 'cookie',

为什么我在添加 session.save() 或将 session.type 更改为 cookie 时会出错？

完整引用：抱歉日期和所有内容，使用 tail -f 完成

这是针对 session.save() 错误：

对于session.save()错误，它说您没有通过设置data_dir会话缓存参数告诉它在哪里保存

对于 cookie 错误，它需要设置一个密钥validate_key，以便在发送到浏览器时可以对 cookie 进行编码，并在从浏览器获取 cookie 时对其进行解码和验证

因此要解决它们，请使用您自己的值添加这些键：

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"
