私のコードの何が問題になっていますか？ WSGI、ビーカー、Python、apache2

StackOverflow https://stackoverflow.com/questions/5847933

質問

私はapache2、python26、多かれ少なかれ最新バージョンのビーカー、mod_wsgiを使用しています

これが私のコードです、私はこれを手に入れました 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)

これは、localhost/beaker2.wsgiに行くときに正常に機能します。 2つの変更を試みると、サイトは失敗します。

1.追加

session.save()

また

2.変更

'session.type': 'cookie',

session.save（）を追加したり、session.typeをCookieに変更したりしたときにエラーが発生するのはなぜですか？

フルトラックバック：日付とすべてをごめんなさい、テールでそれをしました-f

これはsession.save（）エラー用です。

役に立ちましたか？

解決

のために session.save() エラーは、設定して保存する場所を教えていないと書かれています data_dir セッションキャッシュパラメーター

Cookieエラーには、秘密の鍵が必要です validate_key ブラウザに送信されたときにCookieをエンコードし、ブラウザからCookieを取得したときにデコードおよび認証できるように設定します

したがって、それらを解決するために、これらのキーを独自の値で追加します。

ファイルの場合：

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

クッキー用：

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