1. 配置html

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4.     <meta charset="UTF-8">
  5.     <title>User Login</title>
  6. </head>
  7. <body>
  8. <h1> 欢迎登录! </h1>
  9. {# action向login返回post请求 #}
  10. <form action="/login/" method="post">
  11.     用户名: <input type="text" name="username">
  12.     密 码: <input type="text" name="password">
  13.     <input type="submit">
  14. </form>
  15. </body>
  16. </html>

2. 写登录逻辑

test01/views.py

  1. from django.shortcuts import render
  2. from django.shortcuts import HttpResponse
  5. def login(request):
  6.     method = request.method   # 获取用户请求方式
  7.     if method == 'GET':
  8.         return render(request,'login.html')
  9.     else:
  10.         # request.POST 获取的返回结果 <QueryDict: {'username': ['guo'], 'password': ['guo']}>
  11.         username = request.POST.get('username')
  12.         password = request.POST.get('password')
  13.         if username == 'guo' and password == 'guo':
  14.             # HttpResponse 向用户界面返回字符串
  15.             return HttpResponse('登录成功')
  16.         else:
  17.             return HttpResponse('登录失败')

3. 关闭Django的Post认证


django_project/settings.py

  1. MIDDLEWARE = [
  2.     'django.middleware.security.SecurityMiddleware',
  3.     'django.contrib.sessions.middleware.SessionMiddleware',
  4.     'django.middleware.common.CommonMiddleware',
  5.     # 'django.middleware.csrf.CsrfViewMiddleware',  关闭POST校验
  6.     'django.contrib.auth.middleware.AuthenticationMiddleware',
  7.     'django.contrib.messages.middleware.MessageMiddleware',
  8.     'django.middleware.clickjacking.XFrameOptionsMiddleware',
  9. ]

4. 配置url

  1. import test01.views
  3. urlpatterns = [
  4.     path('admin/', admin.site.urls),
  5.     path('index/',test01.views.index),
  6.     path('login/', test01.views.login),   # 新增
  7. ]

5. 验证
