为什么我的index.html不起作用，显示的依然是hello，world
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <h1>HELLO,index！</h1> </body> </html>
from django.shortcuts import render from django.http import HttpResponse def index(request): return render(request, 'index.html')
