python - 为什么我不能连接到我的本地主机 django 开发服务器？

Question

我正在创建一个 Django 应用程序，并且正在设置我的本地测试环境。我可以成功地让 manage.py runserver 工作，但将我的浏览器指向 http://127.0.0.1:8000/、http://0.0 的任何变体.0.0:8000/ 或 http://localhost:8000/ 返回“无法访问此站点”错误。

同时django会抛出301错误:

Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.
[11/Jul/2017 23:35:37] "GET / HTTP/1.1" 301 0

我已成功将应用程序部署到 Heroku(所有 URL 都在那里工作)，但我无法在我的本地机器上运行它。我还尝试了 heroku local 包含的开发服务器来达到同样的效果。

作为引用，我的 django urls.py 文件如下所示:

from django.conf.urls import url
from django.contrib import admin
from recs.views import Request1, Check1, index

urlpatterns = [
    url(r'^$', index, name='index'),
    url(r'^admin/', admin.site.urls),
    url(r'^analyze1/', Request1),
    url(r'^analyze1/status/', Check1),
]

感谢任何帮助!

OP 在原始问题的评论中发布了解决方案，但他/她似乎忘记将其作为答案发布。所以这里是:

Ok so the problem is because of the https, thus getting redirected, as localhost is working on http, try to comment out this line and check SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') and also comment out the sslify from middleware as said by @ShobhitSharma
