1使用者註冊：
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 # 使用者註冊 @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('使用者名稱不能為空') 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 使用者登入：
@csrf_exempt def my_login(request): errors =[] account = None password = None if request.method == "POST": if not request.POST.get('account'): errors.append('使用者名稱不能為空') 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('使用者名稱錯誤') else: errors.append('使用者名稱或密碼錯誤') return render(request,'blog/login.html', {'errors': errors})
3 使用者退出：
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'), ]
