本文實例講述了django 框架實現的用戶注冊、登錄、退出功能。分享給大家供大家參考，具體如下：
1 用戶注冊：
from django.contrib import authfrom django.contrib.auth.models import Userfrom django.views.decorators.csrf import csrf_exemptfrom django.http import HttpResponseRedirect# 用戶注冊@csrf_exemptdef 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_exemptdef 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> </td> <td> <input type = 'text' placeholder="輸入用戶名" name = 'account'> </td> </tr> <tr> <td> <label >密碼:</label> </td> <td> <input type = 'password' placeholder="輸入密碼" name = 'password'> </td> </tr> <tr> <td> <label >確認密碼:</label> </td> <td> <input type = 'password' placeholder="再次輸入密碼" name ='password2'> </td> </tr> <tr> <td> <label>郵箱:</label> </td> <td> <input type="email" placeholder="輸入郵箱" name = 'email'> </td> </tr> <tr> <td> <input type = 'submit' placeholder="Login" value="登錄"> </td> </tr> </form></table></body></html>
