一、URL配置：
# 用户登陆列表 # 用户登陆 url(r'login/', views_study.study_login, name='study_login'), #views.login, name='login'), url(r'^study/login/', views_study.study_login, name='study_login'), url(r'^study/username/', views_study.study_username, name='study_index'), # 用户退出 url(r'logout/', views.logout, name='logout'), # 密码修改 url(r'password_change/', views.password_change, name='password_change'),
二、前端网页内容：
<html lang="en">

def study_login(request):
print ("study_login访问时间点：%s" %datetime.now().strftime("%Y-%m-%d %H:%M:%S.%f"))
if request.method == 'POST':
username = request.POST.get('username')
password = request.POST.get('password')
user = authenticate(username=username, password=password)
if user is not None: # pass authtencation
login(request, user)
return HttpResponseRedirect('/study/username/',status=302)

#return HttpResponse('''<script>alert('用户名或者密码不匹配，请检查......');history.go(-1);</script>''')
