django登录功能（简单在POST请求）
第一 先在templates中创立index.html
!DOCTYPE html> <head> <meta charset="UTF-8"> <title>Django Page</title> </head> <body> <h1>登录页面</h1> <form method="post" action="/login_submit/"> <input name="username" type="text" placeholder="username"><br> <input name="password" type="password" placeholder="password"><br> {{ error }}<br> <button id="btn" type="submit">登录</button> {% csrf_token %} </form> </body> </html>
第二步 关联相关路径 这里路径为http://127.0.0.1:8000/login_submit/
在url.py中
urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^index/$', views.index), url(r'^login_submit/$', views.login_submit),
第三步 定义动作（POST处理登录请求）
在view.py
1 def index(request): 2 return render(request, 'index.html') 3 def login_submit(request): 4 if request.method == 'POST': 5 username = request.POST.get('username', '') 6 password =request.POST.get('password', '') 7 if username == 'admin' and password == 'admin123': 8 return HttpResponse('login success!') 9 else: 10 return render(request,'index.html',{'error':'username or password error'})
