Django应用程序中使用postgres和Gunicorn + Nginx作为反向代理，inputinettypes的dbinput语法无效

你能帮我破译这个相当深奥的错误吗？ 当我启动应用程序时，一切正常，但是当我尝试login崩溃。

DatabaseError在/ login /

inputinettypes的input语法无效：“”LINE 1：… 00101 Firefox / 41.0'，'2015-12-12 09：39：55.590036 + 00：00'，''）

exception位置：/home/mhb11/.virtualenvs/redditpk/local/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/base.py执行中，第54行

• 在Djangopipe理中上传文件时出现UnicodeEncodeError
• 错误：无效的HTTP_HOST标头：'/webapps/../gunicorn.sock'
• Python和Django OperationalError（2006，“MySQL服务器已经消失”）
• django-allauth：如何修改电子邮件确认url？
• Nginx正在抛出一个403 Forbidden on Static Files

我知道， inet数据types接受IPv4和IPv6主机和networking（而不是域名）。

回溯如下：

urls.py中的/ login / url是url(r'^login/$', 'django.contrib.auth.views.login', {'template_name': 'login.html'}, name="login"),

环境是：

Django 1.5.1有一个postgresql后端 ，驻留在Ubuntu 14.04机器上。 尤其要注意的是，在我将nginx设置为gunicorn之后的反向代理 （使用端口80进行此设置）后，此错误开始出现。 当我在端口8080上单独使用gunicorn（和服务员，另一个纯粹的python web服务器）的时候，情况非常好。

在/ etc / nginx的/网站可用/ myproject的：

 server { listen 80; server_name example.cloudapp.net; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/mhb11/folder/myproject; } location / { include proxy_params; proxy_pass http://unix:/home/mhb11/folder/myproject/myproject.sock; } error_page 500 502 503 504 /500.html; location = /500.html { root /home/mhb11/folder/myproject/templates/; } } 

的/ etc / nginx的/ proxy_params：

 proxy_set_header Host $http_host; proxy_set_header User-Agent $http_user_agent; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; 

/etc/nginx/nginx.conf：

 user www-data; worker_processes 4; pid /run/nginx.pid; env ON_AZURE=1; env awsaccesskeyid=something; env awssecretkey=something; events { worker_connections 1024; multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascrip$ ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } #mail { # # See sample authentication script at: # # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript # # # auth_http localhost/auth.php; # # pop3_capabilities "TOP" "USER"; # # imap_capabilities "IMAP4rev1" "UIDPLUS"; # # server { # listen localhost:110; # protocol pop3; # proxy on; # } # # server { # listen localhost:143; # protocol imap; # proxy on; # } #} 

这是怎么回事？

注意：如果需要更多的信息，请向我咨询，例如我的gunicorn.conf和nginx.conf文件，安装的软件包或者是否需要与db相关的东西。 只是要求离开！
