在Python Google App Engine项目中使用gae-session进行的Nosegae单元测试

当我使用单元测试时，无法使gae-sessions正常工作。我不确定它是否是cookie问题或内部gae-sessions问题（它使用memcache /持久性数据存储）。在通过浏览器访问时，它在实际应用程序上运行良好。在Python Google App Engine项目中使用gae-session进行的Nosegae单元测试

我在Mac OS 10.6.6，Google App Engine SDK 1.4.2上使用Python 2.5，nosetests 1.0.0，NoseGAE-0.1.7和gae-sessions v1.06。

这里是我的代码：

Web应用程序执行：

from google.appengine.ext import webapp 
from gaesessions import get_current_session 

class cookietest(webapp.RequestHandler): 
    def get(self): 
     s = get_current_session() 
     if not 'message' in s: 
      self.response.out.write('No session value') 
      s['message'] = 'This value is stored in a session' 
     else: 
      self.response.out.write("Message found: %s" % s['message']) 

application = webapp.WSGIApplication([(r'/cookietest', cookietest)])

单元测试执行：

def test_cookietest(self): 
    from gaesessions import SessionMiddleware 
    app_with_sessions = SessionMiddleware(application, cookie_key=os.urandom(64)) # random key 
    self.app = TestApp(app_with_sessions) 

    resp = self.app.get('/cookietest') 
    cookie = resp.headers['Set-Cookie'] 
    assert cookie 
    resp = self.app.get('/cookietest', headers={'Cookie': cookie}) 
    print resp 
    assert 'This value is stored in a session' in resp

相关的输出是：

我想你必须在这个测试中手动保存会话。

if not 'message' in s: 
     self.response.out.write('No session value') 
     s['message'] = 'This value is stored in a session' 
     s.save()

更新：

gae-sessions检索来自os.environ['HTTP_COOKIE']变量的会话cookie。此值需要在self.app.get请求之前设置，而不是传入headers参数中的cookie。

试过了，仍然没有工作。 – 2011-03-29 13:04:35

Gae-sessions从'os.environ ['HTTP_COOKIE']'变量中检索cookie。我不认为传入“Cookie”标题与设置此值相当。 – Calvin 2011-03-29 19:11:55

谢谢！那工作。我只在我的self.app.get（）请求之前设置了os.environ ['HTTP_COOKIE']，它工作得很好。想要编辑答案或写另一个答案，以便我可以接受它？ – 2011-03-30 06:35:10
