Was ist los mit meinem Code? WSGI, Becher, Python, Apache2

Question

Ich verwende Apache2, Python26, mehr oder weniger neueste Version von Becher, mod_wsgi

Hier ist mein Code, ich habe das von 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)

Das funktioniert gut, wenn ich zu Localhost/Becher2.WSGI gehe. Wenn ich zwei Änderungen ausprobiere, schlägt die Site fehl:

1. Hinzufügen

session.save()

oder

2. Änderung

'session.type': 'cookie',

Warum bekomme ich Fehler, wenn ich Session.save () oder Session.typ an Cookie hinzufüge?

Vollständige Trackback: Entschuldigung für die Daten und alles, hat es mit Tail -f gemacht

Dies ist für die Sitzung.Save () Fehler:

Answer 1

für die session.save() Fehler Es heißt, dass Sie es nicht gesagt haben, wo Sie speichern sollen, indem Sie die festlegen data_dir Session -Cache -Parameter

Für den Cookie -Fehler benötigt es einen geheimen Schlüssel validate_key Setzen Sie so

Um sie zu lösen, fügen Sie diese Schlüssel mit Ihren eigenen Werten hinzu:

Für Datei:

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

Für Kekse:

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