如何在google-app-engine中使用会话

Question

我刚开始使用Python (以及GAE)，我试图在我的应用程序中包含会话，这正是我所做的：

我将高斯文件夹复制到我的src文件夹(该文件夹包括__init__.py文件)

并将其添加到我的工作代码中：

from gaesessions import get_current_session

session = get_current_session()

我收到以下错误：

Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\runtime\wsgi.py", line 174, in Handle result = handler(self._environ, self._StartResponse)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 1519, in __call__ response = self._internal_error(e)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 1511, in __call__ rv = self.handle_exception(request, response, e)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 1505, in __call__ rv = self.router.dispatch(request, response)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 1253, in default_dispatcher return route.handler_adapter(request, response)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 1077, in __call__ return handler.dispatch()

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 547, in dispatch return self.handle_exception(e, self.app.debug)

File "C:\Program Files\Google\google_appengine\lib\webapp2\webapp2.py", line 545, in dispatch return method(*args, **kwargs)

File "D:....\src\helloworld.py", line 13, in get session = get_current_session()

File "D:....\src\gaesessions\__init__.py", line 36, in get_current_session return _tls.current_session

File "C:\Python27\lib\_threading_local.py", line 193, in __getattribute__ return object.__getattribute__(self, name)

Answer 1

您忽略了堆栈跟踪中的实际异常，但我猜是这样的：

AttributeError：“本地”对象没有属性“current_session”

如果是这样的话，您很可能跳过了middleware configuration步骤。根据指令创建一个appengine_config.py并重新启动dev服务器；这将解决您的错误。
