Django认证系统实现的web页面实现代码

结合数据库、ajax、js、Djangoform表单和认证系统的web页面

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
# -*- coding: UTF-8 -*-
# Author:YiJun
from django import forms
from app01 import models
from django.forms import widgets
from django.core.exceptions import ValidationError # 导入异常
import re
# Create your views here.
class Reg_form(forms.Form):
 # 用户名表单
 username = forms.CharField(
  min_length=4,
  label="设置用户名",
  error_messages={
   "required": "不能为空",
   "invalid": "格式错误",
   "min_length": "用户名最少4个字符"
  },
  widget=widgets.TextInput(
   attrs={
    'class': "form-control",
    'placeholder': '用户名'
   })
 )
 # 用户密码设置表单
 pwd = forms.CharField(
  min_length=6,
  label="设置密码",
  widget=forms.widgets.PasswordInput(
   attrs={
    'class': 'form-control',
    'placeholder': '密码'},
   render_value=True,
  ),
  error_messages={
   "required": "不能为空",
   "invalid": "格式错误",
   "min_length": "密码至少6位"

  }
 )
 # 用户密码确认表单
 r_pwd = forms.CharField(
  min_length=6,
  label="确认密码",
  widget=forms.widgets.PasswordInput(
   attrs={
    'class': 'form-control',
    'placeholder': '确认密码'},
   render_value=True,
  ),
  error_messages={
   "required": "不能为空",
   "invalid": "格式错误",
   "min_length": "密码至少6位"

  }
 )
 # 用户性别选择表单
 gender = forms.ChoiceField(
  choices=((1, "男"), (2, "女"), (3, "保密")),
  label="性别",
  initial=3,
  widget=forms.widgets.RadioSelect
 )
 # 用户手机号码表单
 phone = forms.CharField(
  label="手机号码",
  max_length=11,
  min_length=11,
  error_messages={
   "required": "不能为空",
   "invalid": "格式错误",
   "min_length": "手机号码至少11位",
   "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

注册页面

<html lang="en">
<head>
 <meta charset="UTF-8">

   content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">

 <link rel="stylesheet" href="/static/bootstrap-3.3.7/css/bootstrap.min.css" rel="external nofollow" >
 <title>Document</title>
</head>
<body>
<div class="container">
 <div class="row" style="margin-top: 50px">
  <div class="panel panel-primary">

   <div class="panel-heading"><h4>用户详细信息</h4></div>
   <div class="panel-body">

   </div>

   <!-- Table -->
   <div class="table-responsive">
    <table class="table table-bordered">
     <thead>
     <tr>
      <th>#</th>
      <th>用户名</th>
      <th>手机号码</th>
      <th>上次登陆时间</th>
      <th>注册时间</th>
      <th>用户性别</th>
     </tr>
     </thead>
     <tbody>
     <tr>
      <th scope="row">1</th>
      <td>{{ user.username }}</td>
      <td>{{ user.phone }}</td>
      <td>{{ user.last_login|date:'Y-m-d H:i:s' }}</td>
      <td>{{ user.date_joined|date:'Y-m-d H:i:s' }}</td>
      <td>{{ user.gender }}</td>
     </tr>
     </tbody>
    </table>
   </div>
  </div>
  <div style="margin-top: 20px">
   <a class="btn btn-info " href="/modify_pwd/" rel="external nofollow" >修改密码</a>
   <a class="btn btn-danger pull-right" href="/logout/" rel="external nofollow" >注销</a>
  </div>
 </div>
</div>
