javascript - 登录 Python 和 Django 应用程序时本地服务器出现错误

Question

我希望我的 login.html 页面首先作为我的 Python 和 Django 应用程序中的登录页面。但是，当我在填写用户名和密码后按下回车按钮时，服务器上项目的 urls.py 文件中就会显示错误。

项目的URLS.py文件:

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('', include('tabs_app.urls')),
    path('admin/', admin.site.urls),
    path('accounts/', include('accounts.urls'))
]

index.html文件所在项目中应用程序的VIEWS.py文件:

from django.shortcuts import render

# Create your views here.
def login(request):
    return render(request, 'login.html')

index.html文件所在项目中应用程序的URLS.py文件:

from django.urls import path
from . import views

urlpatterns = [
   path('', views.login, name='login')
]

编写LOGIN代码的应用程序的VIEWS.py文件:

from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth.models import User, auth

# Create your views here.

def login(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']

        user = auth.authenticate(username=username,password=password)

        if user is not None:
            auth.login(request, user)
            return redirect('/')

        else:
            messages.info(request, 'invalid credentials')
            return redirect('login')

    else:
        return render(request, 'login.html')

编写LOGIN代码的应用程序的URLS.py文件:

from django.urls import path

from . import views

urlpatterns = [
   path('login', views.login, name='login')
] 

本地服务器上出现错误消息:

Page not found (404)
Request Method: POST
Request URL:    http://127.0.0.1:8000/login
Using the URLconf defined in tabs_pilot.urls, Django tried these URL patterns, in this order:
1. [name='login']
2. admin/
3. accounts/
^media/(?P<path>.*)$
The current path, login, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

Answer 1

您是否正在尝试使用 Django 的内置登录功能？在这种情况下，您的端点是 http://127.0.0.1:8000/accounts/login并且您的模板应该可以在模板目录的注册目录中找到。

Mozilla 在其 Django 教程中很好地概述了这一切是如何工作的。看看here .
