Django2未连接到本地主机

Question

I'm new to Django/Python. I'm currently taking a beginners course and I'm having difficulty setting up my URLs and connecting to a local server. I'm using Python version: 3.7.0 and Django v.2

The command line does not give any errors (0), it tells me to go here:

Starting development server at http://127.0.0.1:8000/

Which I believe is the local host, however the site says

This site can’t be reached
127.0.0.1 refused to connect.

Can anyone let me know what I'm missing I would greatly appreciate it so that I can continue on with my studying. I'm using tutorials on YT Django Tutorial and the guy is using an older Django so I think that may be why I'm having trouble. He says we should still be okay to follow through even on the new version of Django.

urls.py

from django.contrib import admin
from django.urls import path
from.import views

urlpatterns = [
    path('', views.homepage),
    path('admin/', admin.site.urls),
    path('about/', views.about),

]

views.py

from django.http import HttpResponse

def homepage(request):
    return HttpResponse('homepage')
def about(request):
    return HttpResponse('about')

Answer 1

Got it to work. This is what was needed:

ALLOWED_HOSTS = ['localhost', '127.0.0.1']

Took me forever to figure this out. :)

Answer 2

There is a little modification is required in your code: Instead of path('about/', views.about), write this:

path('about/', views.about,name='about'),

after modify this line , run the server and open this http://127.0.0.1:8000/ URL and add /about and then press enter.

http://127.0.0.1:8000/about

Hope it will work in your case
