Question

我使用Cornice制作RESTful网址。

我安装了金字塔烧杯，并按照文档中的说明将包含添加到我的__init__.py。

就是这样。然后我在我的观点中这样做了：

p_desc = """Service to post session. """
p = Service(name='p',\
                    path=root+'/1',\
                    description=register_desc)
g_desc = """Service to get session. """
g = Service(name='g',\
                    path=root+'/2',\
                    description=g_desc)

@g.get()
def view2(request):
    print request.session
    return Response()

@p.post()
def view1(request):
    print 'here'
    request.session['lol'] = 'what'
    request.session.save()
    print request.session
    return Response()

这是我的结果

>>> requests.post('http://localhost/proj/1')
<Response [200]>
>>> requests.get('http://localhost/proj/2')
<Response [200]>

Starting HTTP server on http://0.0.0.0:6543
here
{'_accessed_time': 1346107789.2590189, 'lol': 'what', '_creation_time': 1346107789.2590189}
localhost - - [27/Aug/2012 18:49:49] "POST /proj/1 HTTP/1.0" 200 0

{'_accessed_time': 1346107791.0883319, '_creation_time': 1346107791.0883319}
localhost - - [27/Aug/2012 18:49:51] "GET /proj/2 HTTP/1.0" 200 4

正如您所看到的，它会回馈新会话。如何获得相同的会话以便我可以访问相同的数据？

Answer 1

通过发送给客户端的cookie跟踪会话。因此，您的“客户端”（requests库）需要实际再次发送该cookie：

resp = requests.post('http://localhost/proj/1')
cookies = resp.cookies

requests.get('http://localhost/proj/2', cookies=cookies)

最好还是使用requests.session set-up：

with requests.session() as s:
    s.post('http://localhost/proj/1')
    s.get('http://localhost/proj/2')

举例说明@Martijn Pieters's answer：

import requests

def t(r, url="http://httpbin.org/cookies"): 
    print(r.get(url).json['cookies'])

with requests.session() as s:
    t(requests)             # request without session
    t(s)                    # request within session
    t(s, "http://httpbin.org/cookies/set?name=value")  # set cookie
    t(requests)             # request without session
    t(s)                    # request within session

输出

{}                  # request without session
{}                  # request within session
{u'name': u'value'} # set cookie
{}                  # request without session
{u'name': u'value'} # request within session
