Django——简单版登录功能

前提需要：把框架那些配置啥的都写好

用bootstrap(别人写好的样式)把界面显示的好看点

 

 

一、app02/views.py

from django.shortcuts import render,redirect,HttpResponse# Create your views here.def login(request): if request.method=='GET':  return render(request,'login.html') else:  name=request.POST.get('name')  password=request.POST.get('password')  print(name)  print(password)  if name=='ayca' and password=='123':   # return redirect('http://www.baidu.com')   # 登录成功重定向到index页面   return redirect('/index')  else:   return HttpResponse('用户名密码错误')def index(request): return render(request,'index2.html')

二、settings.py

import os# BASE_DIR：项目根路径BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))# SECRET_KEY：密钥，项目中默认的一些加密用它（不需要关注，可以改，但是不能删）SECRET_KEY = 'dk_'# DEBUG：调试模式，开，开发阶段是true，上线阶段把它设成false# 设置成开报错信息更完善DEBUG = True# ALLOWED_HOSTS：上线阶段使用，允许谁访问ALLOWED_HOSTS = ['*']# INSTALLED_APPS 项目所有的app，新建的app要在里面注册INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # 'app01.apps.App01Config', 'app01', # 'app02.apps.App02Config', # 'app100' #]# MIDDLEWARE 中间件MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', # 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware',]# ROOT_URLCONF 根路由是哪个文件，根路由的位置可以变ROOT_URLCONF = 'day60.urls'# TEMPLATES 模板文件存放路径(如果使用django-admin创建的项目，需要手动配，否则找不到)TEMPLATES = [ {  'BACKEND': 'django.template.backends.django.DjangoTemplates',  'DIRS': [os.path.join(BASE_DIR, 'templates')]  ,  'APP_DIRS': True,  'OPTIONS': {   'context_processors': [    'django.template.context_processors.debug',    'django.template.context_processors.request',    'django.contrib.auth.context_processors.auth',    'django.contrib.messages.context_processors.messages',   ],  }, },]# WSGI_APPLICATION wsgi服务器使用的是哪个WSGI_APPLICATION = 'day60.wsgi.application'# DATABASES 数据库链接配置DATABASES = { 'default': {  'ENGINE': 'django.db.backends.sqlite3',  'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }}# 不用管（内置app相关）AUTH_PASSWORD_VALIDATORS = [ {  'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, {  'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, {  'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, {  'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', },]# 国际化相关，语言，时区LANGUAGE_CODE = 'en-us'TIME_ZONE = 'UTC'USE_I18N = TrueUSE_L10N = TrueUSE_TZ = True# 静态文件配置相关STATIC_URL = '/static/'# 再配一个STATICFILES_DIRS=列表（列表内写路径），单词一个字母都不能错STATICFILES_DIRS=[ os.path.join(BASE_DIR,'static'),]

三、day60/urls.py

from django.conf.urls import urlfrom django.contrib import adminfrom app01 import viewsfrom app02 import views as views2# urlpatterns列表，列表内放了url函数的执行结果# 使用很简单，复制一行，改一下第一个参数（正则表达式），第二个参数是视图函数内存地址urlpatterns = [ url(r'^admin/', admin.site.urls), # 在内部，请求来了，路径匹配成功，内部自动调用index(request),把request传入 # url(r'^index', views.index), # 登录小案例 url(r'^login', views2.login), url(r'^index', views2.index),]

四、static/bootstrap

把已下载好的bootstrap直接拉入，并导入index2里

五、直接导入已下载好的或引用jQurey地址

 

jQuery相关网站官网 https://jquery.com/文档API： http://jquery.cuishifeng.cn/index.html#直接打开复制粘贴到自己创建的.js / .min.js文件下BootCDN jQuery各个版本地址： https://www.bootcdn.cn/jquery/#方式一：本地引入<script src="jquery-3.5.1.min.js"></script><script> //注意，一定在引入jQuery之后，再使用jQuery提供的各种操作</script>#方式二：直接使用CDN<script src="https://cdn.bootcss.com/jquery/3.5.1/jquery.js"></script><script> code...</script>

 

 

 

六、templates\index2.html
