'webapp2_extras.sessions'缺失配置鍵：['secret_key']

Question

我在web應用中使用webapp2進行請求處理，爲模板添加django，在我的項目中添加了webapp2會話。

繼this page，我添加了下面給我的腳本

import webapp2 

from webapp2_extras import sessions 

class BaseHandler(webapp2.RequestHandler): 
    def dispatch(self): 
     # Get a session store for this request. 
     self.session_store = sessions.get_store(request=self.request) 

     try: 
      # Dispatch the request. 
      webapp2.RequestHandler.dispatch(self) 
     finally: 
      # Save all sessions. 
      self.session_store.save_sessions(self.response) 

    @webapp2.cached_property 
    def session(self): 
     # Returns a session using the default cookie key. 
     return self.session_store.get_session() 

config = {} 
config['webapp2_extras.sessions'] = { 
    'secret_key': 'my-super-secret-key', 
} 

不過，現在我得到以下錯誤

Traceback (most recent call last): 
    File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1536, in __call__ 
    rv = self.handle_exception(request, response, e) 
    File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1530, in __call__ 
    rv = self.router.dispatch(request, response) 
    File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1278, in default_dispatcher

    File "/home/user/google_appengine/lib/webapp2/webapp2_extras/sessions.py", line 454, in get_store 
    store = request.registry[key] = factory(request) 
    File "/home/user/google_appengine/lib/webapp2/webapp2_extras/sessions.py", line 308, in __init__ 
    required_keys=('secret_key',)) 
    File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1361, in load_config 
    self._validate_required(key, config, required_keys) 
    File "/home/user/google_appengine/lib/webapp2/webapp2.py", line 1375, in _validate_required 
    'Missing configuration keys for %r: %r.' % (key, missing)) 
Exception: Missing configuration keys for 'webapp2_extras.sessions': ['secret_key'] 

我已經設置了密鑰，使用config。我沒有使用任何其他會議。其他進口

import os,sys, string, time, sha, Cookie 
from django.template import Context, Template 
from django.template.loader import get_template 

Answer 1

你需要的地方包括這個配置，如在WSGI應用程序創建：

app = webapp2.WSGIApplication([('/path', MyHandler), 
           config=config, 
           debug=True) 

Answer 2

的順序很重要：

config = {} 
config['webapp2_extras.sessions'] = { 
    'secret_key': 'my-super-secret-key', 
} 

app = webapp2.WSGIApplication([ 
    ('/', HomeHandler), 
], config=config)
