1.在虚拟环境下创建项目

django-admin startproject test

这里是安装虚拟环境和创建项目的过程

2.创建app(我这里为了方便代码的编写用Pycharm)

创建一个umauth的app

3.对工程目录下的setting做更改，添加mysql数据库接口

]

3.在app下的modle写入模块，
，创建urls文件并写入链接地址

from django.db import models

#模块
class User(models.Model):
    u_name = models.CharField(max_length=20)
    u_password = models.CharField(max_length=255)
    u_ticket = models.CharField(max_length=255,null=True)

    class Meta:
        db_table = 'user'

4.在view下写方法

from django.contrib.auth.hashers import make_password, check_password
from django.http import HttpResponseRedirect, HttpResponse
from django.shortcuts import render

from uauth.models import User

#注册
def regist(request):

    if request.method == 'GET':
        return render(request,'regist.html')
    if request.method == 'POST':
        name = request.POST.get('name')
        password = request.POST.get('password')
        password = make_password(password)
        #不明文显示密码
        User.objects.create(
            u_name=name,
            u_password=password
        )#将写入的数据写入到数据库中
        return HttpResponseRedirect(
            '/uauth/login/'
        )#在注册后跳转到登陆页面
#登陆
def login(request):
    if request.method == 'GET':
        return render(request,'login.html')
    if request.method == 'POST':
        name = request.POST.get('name')
        password = request.POST.get('password')
        if User.objects.filter(u_name = name).exists():#如果输入的账号在数据库中存在
            user = User.objects.get(u_name=name)
            if check_password(password,user.u_password):#如果账号的匹马也匹配
                ticket = 'dsvdsvsvs'  #网页登陆成功后可以看到这个ticket的值
                response = HttpResponse()
                response.set_cookie('ticket',ticket)#令牌，用户登陆成功就会有一个令牌，并传输到数据库中，只要令牌还在浏览器缓存中，用户访问页面就不需要再次输入密码，关闭浏览器后令牌被删除。
                user.u_ticket = ticket
                user.save()
                return HttpResponseRedirect(
            '/uauth/alluser/'
        )#这里返回一个存储所有用户信息的页面
            else:
                return HttpResponse('用户密码错误') #密码不匹配的情况
        else:
            return HttpResponseRedirect('用户不存在')#用户不匹配的情况
#定义一个显示有所有用户信息的方法
def alluser(request):
    users = User.objects.all()
    return render(request,'alluser.html',{'users':users})

5.创建urls文件并添加方法的链接

#网页链接地址
from django.conf.urls import url
from uauth import views

urlpatterns = [
    url(r'^regist/', views.regist),
    url(r'^login/', views.login),
    url(r'^alluser/',views.alluser)
]#点击页面就会执行相应的方法

6.在项目目录中的url文件中添加app的链接

from django.conf.urls import url, include
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^uauth/',include('uauth.urls'))
]

7.在项目文件下添加templates文件并写入返回到浏览器的前端页面

regist.html：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>注册页面</title>
</head>
<body>
    <form action="" method="POST">
        注册姓名：<input type="text" name="name">
        注册密码：<input type="password" name="password">
        <input type="submit" value="提交">
    </form>
</body>
</html>

login.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登录页面</title>
</head>
<body>
    <form action="" method="POST">
        登录姓名：<input type="text" name="name">
        登录密码：<input type="password" name="password">
        <input type="submit" value="提交">
    </form>
</body>
</html>

alluser.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>首页</title>
</head>
<body>
    {% for user in users %}
        姓名：{{ user.u_name }}
        密码：{{ user.u_password }}
        <br>
    {% endfor %}
----------------------------------
    <a href="/uauth/regist">注册</a>
    <a href="/uauth/login">登录</a>
</body>
</html>

5.生成迁移文件并执行迁移

python manage.py makemigrations

python manage.py migrate

将数据迁移到数据库中后就可以在数据库中看到相应的数据和表格了

注册用户

登录刚才注册的用户

登录后返回主页

OK，到这里一个用户注册和登录的过程就完成了，并且我们也可以在数据库中看到我们注册的信息。

这里写图片描述
