Question

我正在关注https://ashokfernandez.wordpress.com/2014/03/11/deploying-a-django-app-to-amazon-aws-with-nginx-gunicorn-git/的教程部署django应用程序。这是我目前的情况：

fab spawn实例创建了安装了nginx和gunicorn的aws实例但是当我尝试访问该机器上的网站时，我收到了400 Bad Request。我检查了nginx-error日志，但是这是空的，nginx-access日志显示它已收到请求。主管日志具有以下内容：

我将ALLOWED_HOSTS从[]改为[＆＃34; *＆＃34;]然后＆＃39; *＆＃39; 当我将其更改为字符串时，我得到了＃34;在此服务器上找不到请求的URL。＆＃34;在其他情况下，我得到了400个不良请求。

这是我第一次在nginx上部署django应用程序而我无法弄清楚问题可能是什么。你能帮我调试一下这个错误吗？在此先感谢!!

PS：如果我需要发布任何配置文件，请告诉我。到目前为止，我刚刚遵循了教程，并没有更改任何配置。

更新： common.py

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
SECRET_KEY = 'blah'
ALLOWED_HOSTS = []

    }
}

# Static files via Amazon S3 (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.6/howto/static-files/

INSTALLED_APPS += ('storages',)
AWS_STORAGE_BUCKET_NAME = "xyz"
STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
S3_URL = 'http://%s.s3.amazonaws.com/' % AWS_STORAGE_BUCKET_NAME
STATIC_URL = S3_URL

另外在我的项目配置文件中 fabconf [＆＃39; DOMAINS＆＃39;] =＆＃34;＆＃34; 我认为这也可能是相关的

允许的主机必须匹配您将使用的主机名。因此，将ALLOWED_HOSTS = []放在特定于您的环境（开发或生产）的设置文件中。在开发方面将其设置为ALLOWED_HOSTS = ['localhost', '127.0.0.1']，在生产设置上将其设置为您的域名＆amp;服务器IP。

来自文档：

此列表中的值可以是完全限定名称（例如'www.example.com'），在这种情况下，它们将与完全匹配请求的Host标题（不区分大小写， 不包括端口）。以句点开头的值可用作子域通配符：'.example.com'将匹配example.com，www.example.com以及example.com的任何其他子域。值'*'将匹配任何内容;在这种情况下，您有责任提供自己的Host标头验证（可能在中间件中;如果是，则必须首先在MIDDLEWARE_CLASSES中列出此中间件）。

您获得的状态400响应是由于当您的主机标头与该列表中的任何值不匹配时引发SuspiciousOperation exception。

nginx + gunicorn + django + aws糟糕的请求
