为什么我无法连接到本地主机 django 开发服务器？

我正在创建一个 django 应用程序并正在设置本地测试环境。我可以成功得到manage.py runserver工作但将我的浏览器指向任何变体http://127.0.0.1:8000/, http://0.0.0.0:8000/, or 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），但我无法让它在本地计算机上运行。我也尝试过heroku local包含的开发服务器具有相同的效果。

作为参考，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),
]

任何帮助表示赞赏！

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：

好吧，问题是因为 https，因此被重定向，如下 localhost 正在处理 http，尝试注释掉这一行并检查 SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') 并且 正如 @ShobhitSharma 所说，注释掉中间件中的 sslify
