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
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。

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"
