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

<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<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>
<script src="/static/jquery-3.3.1.min.js"></script>
<script src="/static/bootstrap-3.3.7/js/bootstrap.min.js"></script>
</body>
</html>
