错误错误请求 (400)，当我访问域上的站点时

Question

我在 digitalocean.com 开始了 django 项目。问题是在我的 ip 地址上我的站点已加载并且没有问题，但是如果我通过域，"Bad Request error (400)"。在 godaddy.com 购买的域名。域设置与托管教程一致 https://www.digitalocean.com/community/tutorials/how-to-point-to-digitalocean-nameservers-from-common-domain-registrars:

ns1.digitalocean.com
ns2.digitalocean.com
ns3.digitalocean.com

配置 nginx：

upstream bbb_app_server {
  # fail_timeout=0 means we always retry an upstream even if it failed
  # to return a good HTTP response (in case the Unicorn master nukes a
  # single worker for timing out).

  server unix:/webapps/bbb/run/gunicorn.sock fail_timeout=0;
}

server {

    listen   80;
    server_name example.ru;

    client_max_body_size 4G;

    access_log /webapps/bbb/logs/nginx-access.log;
    error_log /webapps/bbb/logs/nginx-error.log;

    location /static/ {
        alias   /webapps/bbb/static/;
    }

    location /media/ {
        alias   /webapps/bbb/media/;
    }

    location / {
        # an HTTP header important enough to have its own Wikipedia entry:
        #   http://en.wikipedia.org/wiki/X-Forwarded-For
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;


        # enable this if and only if you use HTTPS, this helps Rack
        # set the proper protocol for doing redirects:
        # proxy_set_header X-Forwarded-Proto https;

        # pass the Host: header from the client right along so redirects
        # can be set properly within the Rack application
        proxy_set_header Host $http_host;

        # we don't want nginx trying to do something clever with
        # redirects, we set the Host: header above already.
        proxy_redirect off;

        # set "proxy_buffering off" *only* for Rainbows! when doing
        # Comet/long-poll stuff.  It's also safe to set if you're
        # using only serving fast clients with Unicorn + nginx.
        # Otherwise you _want_ nginx to buffer responses to slow
        # clients, really.
        # proxy_buffering off;

        # Try to serve static files from nginx, no point in making an
        # *application* server like Unicorn/Rainbows! serve static files.
        if (!-f $request_filename) {
            proxy_pass http://bbb_app_server;
            break;
        }
    }

    # Error pages
    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /webapps/bbb/static/;
    }

这是我对 settings.py 的设置：

try:
    from .settings_prod import *
except:
    pass

这是我对 settings_prod.py 的设置：

    DEBUG = False
ALLOWED_HOSTS = ['0.80.00.000',
                 '.example.ru']

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'db1',
        'USER': 'bbb',
        'PASSWORD': 'bbb',
        'HOST': 'localhost',
        'PORT': '',
    }
}

已检查 nginx -t:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

您处理设置的方式似乎有问题。

如果我没理解错的话，你有一个settings.py和一个settings_prod.py.

然后，在 settings.py 中，您正在导入来自 settings_prod.py.[=13 的所有信息=]

我认为正在发生的事情是，这个导入发生在文件的顶部。然后，可能在 settings.py 的其余部分中，您可能还有另一个 ALLOWED_HOSTS，它覆盖了 [=26= 中定义的 ALLOWED_HOSTS = ['0.80.00.000', '.example.ru'] ]settings_prod.py.

如果移动以下代码：

try:
    from .settings_prod import *
except:
    pass

到settings.py文件的底部，它会正确覆盖配置。
