Django认证系统实现的web页面

Posted 2020-12-30 Leslie-x

在学习了Django认证系统后，对于利用Django实现web开发的流程有了初步了解。结合这一段时间的所学，做了个web页面。结合数据库、ajax、js、Djangoform表单和认证系统等

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
