python登录注册界面

本篇文章给大家谈谈python注册用户名和密码登录，以及python写简单的注册登录，希望对各位有所帮助，不要忘了收藏本站喔。

1、settings.py

激活应用


INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'myapp'#激活应用
]

连接数据库，这里是SQL server


##连接数据库
DATABASES = {
     'default': {
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'bishe',
        'USER':'sa',
        'PASSWORD':'root',
        'HOST':'localhost',
        'PORT':'',
        'OPTIONS': {
              'driver':'SQL Server Native Client 11.0',
              'MARS_Connection': True,
         }
    }
}

注释掉这句话
在这里插入图片描述

记得改位置

2.在myapp文件夹下创建文件夹Templates

用来存html文件， index.html, login.html,register.html，三个文件后边展示代码

在项目的urls.py文件中加入两句话


from django.contrib import admin
from django.urls import path
from django.urls import path, include  #1
 
urlpatterns = [
    path('admin/', admin.site.urls),
    path('myapp/', include('myapp.urls')) #2
]

在myapp文件夹里新建urls.py文件
输入代码：


from django.urls import path
from . import views
urlpatterns = [
    path('registe/', views.register,name='register'),
    path('log/', views.login,name='login'),
]

在myapp里的models.py文件中输入类：


from django.db import models
 
 
# Create your models here.
 
class User(models.Model):
    name = models.CharField(max_length=50)
    password = models.CharField(max_length=50)
    telephone = models.CharField(max_length=50,primary_key=True)
    email = models.CharField(max_length=50)
 
    #定义默认输出格式
    def __str__(self):
        return "%s,%s,%s,%s"%(self.name,self.password,self.telephone,self.email)
 
    #自定义对应的表名
    class Meta:
        db_table="user"

在Myapp里的views.py中输入代码


from django.shortcuts import redirect, render
from django.http import HttpResponse
from myapp.models import User
from django.contrib.auth import authenticate,login,logout
from django.contrib.auth.backends import ModelBackend
 
# Create your views here.
def index(request):
    login_msg="恭喜！登录成功"
    return render(request,'index.html',{'login_msg':login_msg})
 
 
def register(request):
    if request.method=='POST':
        userName=request.POST.get('userName')
        userTelephone=request.POST.get('userTel')
        userEmail=request.POST.get('userEmail')
        userPassword=request.POST.get('userPassword')
        userRePassword=request.POST.get('userRePassword')
        try:
            user=User.objects.get(telephone=userTelephone)
            if user:
                msg="用户已存在"
                return render(request,'register.html',{'msg':msg})
        except:
            if userPassword!=userRePassword:
                error_msg="密码不一致"
                return render(request,'register.html',{'error_msg':error_msg})
            else:
                register=User()
                register.name=userName
                register.telephone=userTelephone
                register.password=userPassword
                register.emaild=userEmail
                register.save()
                return redirect('/myapp/log/')
    else:
        return render(request,'register.html')
 
def login(request):
    if request.method=='POST':
        userTelephone=request.POST.get('usertel')
        userPassword=request.POST.get('userpassword')
        if User.objects.get(telephone=userTelephone):
           if User.objects.get(telephone=userTelephone).password==userPassword:
                msg='恭喜登录成功！'
                return render(request,'index.html',{'login_msg':msg})
           else:
                msg='手机号或密码错误'
                return render(request,'login.html',locals(),{'msg':msg})
        else:
             msg='用户不存在，请先注册！'
             return render(request,'login.html',locals(),{'msg':msg})
    else:
        return render(request,'login.html')
