使用webtest.TestApp时我的Cookie未被传输

Question

我对如何在使用Python的webtest发送请求时传递cookies感到困惑。

我有以下测试：

def test_commenting_and_voting(self):
    https = {'wsgi.url_scheme': 'https'}
    users = []
    for user in USERS:
      resp_post = self.testapp.post_json('/user', user)
      users.append(resp_post.json.get('id'))

    self.testapp.post_json('/login/%s' % users[0],
                           {'password' : USERS[0]['password']},
                           extra_environ=https)
    print "testapp's view of the cookiejar"
    print self.testapp.cookies
    print "END"
    resp_post = self.testapp.post_json('/comment', {'value': ""})

还有以下处理程序：

class CommentHandler(webapp2.RequestHandler):

    def get(self, id=None):
        get_from_urlsafe(self, id)

    @ndb.transactional
    def post(self, id=None):
        assert False, self.request.cookies

我在处理函数中抛出一个错误，以便查看cookies。看起来虽然cookies在webtest.TestApp的cookiejar里，但在进行wsgi请求时并没有被发送。那么我该如何让cookies被发送呢？

Using scent:
test_commenting_and_voting (test_models.test_Models) ... 
testapp's view of the cookiejar
{'secret': '58bd5cfd36e6f805de645e00f8bea9d70ae5398ff0606b7fde829e6732394bb7', 'session': 'agx0ZXN0YmVkLXRlc3RyIgsSD1VzZXJFbnRpdHlHcm91cBgBDAsSB1Nlc3Npb24YCww'}
END

没关系。我之前看不到那些 cookies 的原因是因为它们被设置为安全 cookies，这意味着只有在使用安全连接时它们才会存在。而我测试的时候使用的是不安全的连接。

要让这个正常工作，改成下面的请求：

self.testapp.post_json('/comment', 
                       {'value': ""}, 
                       extra_environ={'wsgi.url_scheme': 'https'})
