加载新实例似乎没有什么用。因此,当一个处理程序被加载并尝试使用时,您可以使用
user = self.auth.get_user_by_session()
webapp2没有正确加载,因为如果我刷新并点击相同的实例,错误消失。有没有人看到这个错误,任何帮助或方向将大大apreciated。
编辑:
多一点信息。我使用
库:
- 名称:webapp2
版本:latest
和python 2.7。我的BaseHandler看起来像这样
class BaseHandler(webapp2.RequestHandler):
BaseHandler for所有请求
持有auth和session属性,以便它们可以被所有请求访问
def dispatch(self):
#获取会话存储这个请求。
self.session_store = sessions.get_store(request = self.request)
try:
#发送请求。
webapp2.RequestHandler.dispatch(self)
finally:
#保存所有会话。
self.session_store.save_sessions(self.response)
@ webapp2.cached_property
def auth(self):
return auth.get_auth()
@ webapp2.cached_property
def session(self):
#使用默认cookie密钥返回一个会话。
返回self.session_store.get_session()
@ webapp2.cached_property
def session_store(self):
return sessions.get_store(request = self.request)
@ webapp2.cached_property
def messages(self):
return self.session.get_flashes(key ='_ messages')
def add_message(self ,message,level = None):
self.session.add_flash(message,level,key ='_ messages')
@ webapp2.cached_property
def user(self):
返回self.auth.get_user_by_session()
app = ndb.toplevel(webapp2.WSGIApplication(routes.URLS,debug = config.DEBUG,config = config.CONFIG))
webapp2出错了吗?
这似乎是Webapp2库中的一个Bug,如下所述: https://groups.google.com/forum/?fromgroups=#!topic/webapp2/sHb2RYxG DLc
Im getting really frustrated with this error. After i updated to sdk 1.6.6 im starting to see the following error the first time i run certain handlers.
AssertionError: Request global variable is not set.
the important part of the stacktrace
Request global variable is not set.

It seems like something isnt going right when loading up a new instance. So that when a handler gets loaded and try to use
user = self.auth.get_user_by_session()
webapp2 isnt loaded properly, because if i refresh and hit the same instance the error goes away. Has anyone seen this error, any help or direction would be greatly apreciated.
EDIT:
A little more info. Im using
libraries:
- name: webapp2
version: latest
and python 2.7 . my BaseHandler looks like this
class BaseHandler(webapp2.RequestHandler):
"""
BaseHandler for all requests
Holds the auth and session properties so they are reachable for all requests
"""
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 auth(self):
return auth.get_auth()
@webapp2.cached_property
def session(self):
# Returns a session using the default cookie key.
return self.session_store.get_session()
@webapp2.cached_property
def session_store(self):
return sessions.get_store(request=self.request)
@webapp2.cached_property
def messages(self):
return self.session.get_flashes(key='_messages')
def add_message(self, message, level=None):
self.session.add_flash(message, level, key='_messages')
@webapp2.cached_property
def user(self):
return self.auth.get_user_by_session()
app = ndb.toplevel(webapp2.WSGIApplication(routes.URLS, debug=config.DEBUG, config=config.CONFIG))
Something is wrong with webapp2 ?
This seems to be a Bug in the Webapp2 library as discussed here: https://groups.google.com/forum/?fromgroups=#!topic/webapp2/sHb2RYxGDLc
