在此服务器 django 上找不到请求的 URL

Question

我正在关注 youtube 教程，但遇到错误...

遇到错误

The requested URL /hello was not found on this server.

网站/urls.py

urlpatterns = patterns('',
    url(r'^hello/$', article.views.hello),
    ...
)

文章/views.py

from django.shortcuts import render
from django.http import HttpResponse

def hello(request):
  name = 'mike'
  html = '<html><body> sup %s </body></html> ' %name
  return HttpRequest(html)

网站/settings.py

INSTALLED_APPS = (
    ...
    'article',
)

Answer 1

请求 URL /hello 没有尾部斜杠 (/)。您可以通过附加 ? 来使 url 模式匹配 /：

url(r'^hello/?$', article.views.hello),
