【中文标题】错误 Bad Request (400),当我访问域上的站点时【英文标题】:error Bad Request (400), when I go to the site on the domain 【发布时间】:2018-07-27 09:32:03 【问题描述】:

我在 digitalocean.com 上启动了 django 项目。问题是在我的 IP 地址上加载了我的网站并且没有问题,但是如果我通过域,“错误请求错误(400)”。在 godaddy.com 购买的域名。域名设置正确按照托管教程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': '',
    

检查了 nginx -t:

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

【问题讨论】:

如果直接输入digitalocean ip就可以了? 是的,它在 ip address digitalocean.com 上运行良好 可以分享你的ip和域名吗?看起来记录不匹配 你检查 nginx 访问和错误日​​志了吗? nginx:配置文件/etc/nginx/nginx.conf语法没问题 nginx:配置文件/etc/nginx/nginx.conf测试成功 【参考方案1】:

您处理设置的方式似乎是问题所在。

如果我理解正确,您有一个 settings.py 和一个 settings_prod.py

然后,在 settings.py 中,您将从 settings_prod.py 导入所有信息。

我认为正在发生的是,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,您可能有另一个 ALLOWED_HOSTS,它会覆盖您在 settings_prod.py 中定义的 ALLOWED_HOSTS = ['0.80.00.000', '.example.ru']。。 p>

如果移动以下代码:

try:
    from .settings_prod import *
except:
    pass

settings.py文件的底部,它将正确覆盖配置。

【讨论】:

是的,您对 settings.py 和 settings_prod.py 的理解正确。但是try: from .settings_prod import * except: pass在文件settings.py的底部 暂时将DEBUG 更改为True,重新启动 Gunicorn 进程并访问该页面,看看您遇到了什么错误。或者,如果您已正确配置日志记录,请检查 Gunicorn 的日志。 最后,我按照settings.py中的设置更改了设置并重新启动。
