Python Django 注册并使用确认邮件登录

Django默认提供了一个认证系统配置。用户对象是认证系统的核心。今天我们将实现Django的认证系统。

需要的模块：

• django : django安装
• crispy_forms :

pip install --upgrade django-crispy-forms

基本设置：
通过以下命令启动一个项目-

 django-admin startproject project

将目录改为项目-

 cd project

启动服务器- 通过在终端键入以下命令启动服务器 –

 python manage.py runserver

要检查服务器是否在运行，请进入一个网页浏览器，输入http://127.0.0.1:8000/_ 作为URL。
现在，通过按以下步骤停止服务器

ctrl-c

让我们现在创建一个名为 “用户 “的应用程序。

python manage.py startapp user

通过操作进入用户/文件夹。cd user并创建一个文件夹templates，里面有index.html, login.html, Email.html, register.html文件。

用一个文本编辑器打开项目文件夹。目录结构应该是这样的。

现在在settings.py中的todo_site中添加 “user “应用程序和 “crispy_form”，并添加

CRISPY_TEMPLATE_PACK = 'bootstrap4'

在settings.py的最后

在setting.py中配置邮件设置。

把你的电子邮件和密码放在这里。

编辑 urls.py 项目中的文件：

from django.contrib import admin
from django.urls import path, include
from user import views as user_view
from django.contrib.auth import views as auth
 
urlpatterns = [
 
    path('admin/', admin.site.urls),
 
    ##### user related path##########################
    path('', include('user.urls')),
    path('login/', user_view.Login, name ='login'),
    path('logout/', auth.LogoutView.as_view(template_name ='user/index.html'), name ='logout'),
    path('register/', user_view.register, name ='register'),
 
]

在用户中编辑urls.py :

from django.urls import path, include
from django.conf import settings
from . import views
from django.conf.urls.static import static
 
urlpatterns = [
         path('', views.index, name ='index'),
]

在用户中编辑 views.py:

from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth import authenticate, login
from django.contrib.auth.decorators import login_required
from django.contrib.auth.forms import AuthenticationForm
from .forms import UserRegisterForm
from django.core.mail import send_mail
from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
from django.template import Context
  
  
#################### index#######################################
def index(request):
    return render(request, 'user/index.html', {'title':'index'})
  
########### register here #####################################
def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            email = form.cleaned_data.get('email')
            ######################### mail system ####################################
            htmly = get_template('user/Email.html')
            d = { 'username': username }
            subject, from_email, to = 'welcome', 'your_email@gmail.com', email
            html_content = htmly.render(d)
            msg = EmailMultiAlternatives(subject, html_content, from_email, [to])
            msg.attach_alternative(html_content, "text/html")
            msg.send()
            ##################################################################
            messages.success(request, f'Your account has been created ! You are now able to log in')
            return redirect('login')
    else:
        form = UserRegisterForm()
    return render(request, 'user/register.html', {'form': form, 'title':'register here'})
  
################ login forms###################################################
def Login(request):
    if request.method == 'POST':
  
        # AuthenticationForm_can_also_be_used__
  
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username = username, password = password)
        if user is not None:
            form = login(request, user)
            messages.success(request, f' welcome {username} !!')
            return redirect('index')
        else:
            messages.info(request, f'account done not exit plz sign in')
    form = AuthenticationForm()
    return render(request, 'user/login.html', {'form':form, 'title':'log in'})

在这里配置你的电子邮件。

现在在用户中创建一个 forms.py :

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
 
 
 
class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()
    phone_no = forms.CharField(max_length = 20)
    first_name = forms.CharField(max_length = 20)
    last_name = forms.CharField(max_length = 20)
    class Meta:
        model = User
        fields = ['username', 'email', 'phone_no', 'password1', 'password2']

浏览到 templates/user/ 并编辑文件：

• 链接到index.html文件
• 链接到Email.html
• 链接到login.html
• 链接到register.html

制作迁移程序并进行迁移。

python manage.py makemigrations
python manage.py migrate

现在你可以运行服务器来查看你的应用程序。

python manage.py runserver
