python请求模块不加载响应内容

Question

我在使用python请求模块对我的应用程序进行doctest时遇到了一些问题，直到现在才能得到它。 有时会发生缺少响应主体的情况。但是当我用ngrep查看网络请求/响应时，我可以看到响应正文。所以它似乎被python模块忽略了。这使我的doctests非常不稳定，从而无用。

>>> response = requests.get('/api/v1/profile/%s/affiliations' % urllib.quote(profileId1))
>>> affiliations = response.json
>>> pprint(affiliations)
[{u'name': u'Affiliation A'},
 {u'name': u'Affiliation B'}]

Failed example:
    pprint(affiliations)
Differences (ndiff with -expected +actual):
    + None
    - [{u'name': u'Affiliation A'},
    -  {u'name': u'Affiliation B'}]

ngrep跟踪如下所示：
