这篇文章将为大家详细讲解有关使用Django认证系统怎么实现web页面，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。
一：数据模块
扩展了Django中的user表，增加了自定义的字段
from django.db import models from django.contrib.auth.models import AbstractUser # Create your models here. class UserInfo(AbstractUser): phone = models.CharField(max_length=11) gender = models.CharField(max_length=2)
二：路由系统
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^register/',views.register), url(r'^login/',views.login_view), url(r'^home/',views.home), url(r'^logout/',views.logout_view), url(r'^modify_pwd/',views.modify_pwd), url(r'^$',views.home), ]
三：视图系统
from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from django.http import JsonResponse
from django.contrib.auth import authenticate, login,logout
from app01 import forms
from app01.models import UserInfo
# Create your views here.
def register(request):
form_obj = forms.Reg_form()
if request.method == 'POST':
form_obj = forms.Reg_form(request.POST)
if form_obj.is_valid():
info_dic = form_obj.cleaned_data
sex_dic = {'1':'男','2':'女','3':'保密'}
info_dic['gender']=sex_dic[info_dic['gender']]
UserInfo.objects.create_user(
username=info_dic['username'],
password = info_dic['pwd'],
gender=info_dic['gender'],
phone =info_dic['phone']
)
return redirect('/login/')
return render(request, "register.html",{'form_obj':form_obj})
def login_view(request):
if request.method == 'POST':
username = request.POST.get('username')
pwd = request.POST.get('pwd')
user = authenticate(username=username, password=pwd)
if user:
login(request, user)
data = {'code':1}
else:
data = {'code': 0,'msg':'用户名或密码错误'}
return JsonResponse(data)
return render(request, 'login.html')
@login_required
def logout_view(request):
logout(request)
return redirect('/login/')
@login_required
def home(request):
user_id = request.session['_auth_user_id']
use_obj = request.user
return render(request,'home.html',{'user':use_obj})
@login_required
def modify_pwd(request):
if request.method == 'POST':
old_pwd = request.POST.get('old_pwd')
pwd = request.POST.get('pwd')
re_pwd = request.POST.get('re_pwd')
user_obj = request.user
if user_obj.check_password(old_pwd):
if re_pwd == pwd:
user_obj.set_password(pwd)
user_obj.save()
data = {'code': 1}
else:
data = {'code': 0, 'msg': '两次输入密码不一致'}
else:
data = {'code': 0, 'msg': '原始密码输入错误'}
return JsonResponse(data)
return render(request,'modify_pwd.html')四：form表单
#!/usr/bin/env python

from django import forms

)
# 用户密码设置表单

# 用户性别选择表单

# 用户手机号码表单

"max_length": "手机号码最多11位",
},
widget=widgets.TextInput(attrs={'class': "form-control",'placeholder': '手机号码'})
)
def clean_phone(self):
value = self.cleaned_data['phone']
expression = re.compile('^1[3589][0-9]{9}')
if not expression.search(value).group():
raise ValidationError('请输入正确的手机号码')
else:
return value
def clean_username(self):
value = self.cleaned_data['username']
if models.UserInfo.objects.filter(username=value):
raise ValidationError('用户名已经注册')
else:
return value
def clean(self):
pwd = self.cleaned_data.get("pwd")
r_pwd = self.cleaned_data.get("r_pwd")
if pwd != r_pwd:
self.add_error("r_pwd", "两次输入的密码不一致！")
# 两次输入的密码不一致
raise ValidationError("两次输入的密码不一致！")
else:
self.cleaned_data.pop('r_pwd')
return self.cleaned_data五：模板系统
