Python 浏览器在@login_required上正确重定向，但在使用urllib2时不正确重定向

我正在用unnitest.TestCase测试Django应用程序

if test['auth']:
    full_url = '{}/{}'.format(host, test['url'])
    request = urllib2.Request(full_url)
    cj = cookielib.CookieJar()
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
    urllib2.install_opener(opener)

    urlh = urllib2.urlopen(full_url)
    html = urlh.read()

    doc = BeautifulSoup(html)
    csrf_input = doc.find(attrs = dict(name = 'csrfmiddlewaretoken'))
    csrf_token = csrf_input['value']

    params = urllib.urlencode(dict(username = test['username'], password=test['password'], 
           csrfmiddlewaretoken = csrf_token, user=CustomUser.objects.get(id=2), next=test['url']))
    urlh = urllib2.urlopen(full_url, params)
    output = urlh.read()
    print 'Checking {} for "{}" string at {}.'.format(test['url'], test['test_string'], host)
    print output
    if test['test_string'] in output:
        return True
    else:
        return False

进入此页面的测试数据如下所示：

{
    'url' : '/manager/',
    'test_string' : 'Manage your jobs',
    'comment' : 'testing string in page',
    'hosts' : (hosts['test'],),
    'auth' : True,
    'username' : 'poster',
    'password' : 'poster',
    'active' : True,
},

*为了完整性起见：hosts['test']等于'http://:' 它为主机中的主机调用http\u字符串\u测试仪：

我试图检查的页面要求用户登录（此页面url为“/manager/”）：

登录视图（'/auth/login/'）如下所示：

def dologin(request):

    message = 'blah'
    user = []

    if request.method == 'POST':

        username = request.POST['username']
        password = request.POST['password']

        user = authenticate(
            username = username,
            password = password,
        )

        if user is not None and hasattr(user, 'verified'):
            if user.verified and user.is_active:
                message = 'authenticated'
                login(request, user)

                # This section seems to be required so that I can redirect properly in 
                # the browser but in the test it seems to be a hindrance.
                if request.POST['next'] is not None:
                    print 'NEXT is '+str(request.POST['next'])
                    return HttpResponseRedirect(request.POST['next'])
                else:
                    return HttpResponseRedirect('/')


        # .............. #

    # The rest
    if request.method == 'GET' and 'next' in request.GET:
        next = request.GET['next']
    else:
        next = None

    print 'NEXT is '+str(next)

    return render_to_response(
        'auth/login.html',
        {
            'page_title' : 'Log in to {}'.format(SITENAME),
            'app_name' : SITENAME,
            'message' : message,
            'next' : next,
        },
        context_instance = RequestContext(request),
    )

当我运行测试时，我在日志（从.manage.py runserver）中获得以下内容：

我猜它没有正确设置cookie，尽管我不知道为什么。如果您包含了一些代码来打印所有HTTP请求和响应头，它应该有助于跟踪问题。您选择这种方式而不是Django TestCase工具，有什么原因吗？只是好奇，不要批评！看起来你在使用Django的内置身份验证系统，IIRC要求你也使用它的内置会话系统，但我没有看到会话cookie被设置。在使用您的web浏览器时，它是否设置了任何会话cookies？嗨，limelights，这是一个很好的问题，我更愿意这样做，但我还没有找到一组对我有意义或对我有帮助的好例子。我看到的当然是django文档网站。我也对这个问题持开放态度（我意识到从技术上讲这是个离题的话题，但无论如何我都会持开放态度）。。。你指的可能是这样的吗？
