1 用戶注冊：
from django.contrib import auth
from django.contrib.auth.models import User
from django.views.decorators.csrf import csrf_exempt
from django.http import HttpResponseRedirect
# 用戶注冊
@csrf_exempt
def register(request):
errors = []
account = None
password = None
password2 = None
email = None
CompareFlag = False
if request.method == 'POST':
if not request.POST.get('account'):
errors.append('用戶名不能為空')
else:
account = request.POST.get('account')
if not request.POST.get('password'):
errors.append('密碼不能為空')
else:
password = request.POST.get('password')
if not request.POST.get('password2'):
errors.append('確認密碼不能為空')
else:
password2 = request.POST.get('password2')
if not request.POST.get('email'):
errors.append('郵箱不能為空')
else:
email = request.POST.get('email')
if password is not None:
if password == password2:
CompareFlag = True
else:
errors.append('兩次輸入密碼不一致')
if account is not None and password is not None and password2 is not None and email is not None and CompareFlag :
user = User.objects.create_user(account,email,password)
user.save()
userlogin = auth.authenticate(username = account,password = password)
auth.login(request,userlogin)
return HttpResponseRedirect('/blog')
return render(request,'blog/register.html', {'errors': errors})2 用戶登錄：
@csrf_exempt
def my_login(request):
errors =[]
account = None
password = None
if request.method == "POST":
if not request.POST.get('account'):
errors.append('用戶名不能為空')
else:
account = request.POST.get('account')
if not request.POST.get('password'):
errors = request.POST.get('密碼不能為空')
else:
password = request.POST.get('password')
if account is not None and password is not None:
user = auth.authenticate(username=account,password=password)
if user is not None:
if user.is_active:
auth.login(request,user)
return HttpResponseRedirect('/blog')
else:
errors.append('用戶名錯誤')
else:
errors.append('用戶名或密碼錯誤')
return render(request,'blog/login.html', {'errors': errors})3 用戶退出：
def my_logout(request):
auth.logout(request)
return HttpResponseRedirect('/blog')URL：
urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^p/(?P<article_id>[0-9]+)/$', views.detail,name='detail'), url(r'^register/$',views.register, name='register'), url(r'^login/$',views.my_login, name='my_login'), url(r'^logout/$',views.my_logout, name='my_logout'), ]
注冊 HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% if errors %}
<li>
{% for error in errors %}
<p >
{{error}}
</p>
{% endfor %}
</li>
{% endif %}
<table>
<form action="" method="post">{% csrf_token %}
<tr>
<td>
<label >用戶名:</label>

<input type = 'text' placeholder="輸入用戶名" name = 'account'>
