无法在 django admin 上发布 - 无法将字节连接到字符串

Question

我在 apache 1and1 共​​享主机上使用 Django 2.0.9 和 Python 3.4.2。

当我向我的 Djando 应用程序发出任何 POST HTTP 请求时，我会收到以下消息：

追溯：

文件“.../python3.4/site-packages/django/core/handlers/exception.py” 在内部 35. response = get_response(request)

文件“.../python3.4/site-packages/django/core/handlers/base.py”在 _get_response 119. response = middleware_method(request, callback, callback_args, callback_kwargs)

文件“.../python3.4/site-packages/django/middleware/csrf.py”在 进程视图 289. request_csrf_token = request.POST.get('csrfmiddlewaretoken', '')

文件“.../python3.4/site-packages/django/core/handlers/wsgi.py”在 _get_post 115. self._load_post_and_files()

文件“.../lib/python3.4/site-packages/django/http/request.py”在 _load_post_and_files 302. self._post, self._files = QueryDict(self.body, encoding=self._encoding), MultiValueDict()

正文中的文件“.../python3.4/site-packages/django/http/request.py” 263. self._body = self.read()

读取文件“.../python3.4/site-packages/django/http/request.py” 322. return self._stream.read(*args, **kwargs)

文件“.../python3.4/site-packages/django/core/handlers/wsgi.py”在 读 36. 结果 = self.buffer + self._read_limited()

异常类型：/adminlogin/ 处的 TypeError 异常值：不能 将字节连接到 str

我发布了管理员登录页面的跟踪，但是任何 POST 请求都是同样的问题。

这是我的 settings.py：

#Cookie Domain
CSRF_COOKIE_DOMAIN='mydomain.es'
SESSION_COOKIE_DOMAIN = ['mydomain.es', 'www.mydomain.es', 'localhost']

BASE_URL='mydomain.es'
CSRF_TRUSTED_ORIGINS=['mydomain.es']
ALLOWED_HOSTS = ['localhost', 'mydomain.es', 'www.mydomain.es']

},
},
]

WSGI_APPLICATION = 'myapp.wsgi.application'

我的 .htaccess：

AddHandler cgi-script .fcgi
RewriteEngine on
RewriteBase /
# Set up static content redirect:
RewriteRule ^(static/.*)$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(media/.*)$ - [L]
RewriteRule ^(adminmedia/.*)$ - [L]
# The following two lines are for FastCGI:
RewriteCond %{REQUEST_URI} !(application.fcgi)
RewriteRule ^(.*)$ application.fcgi/$1 [QSA,L]

我的应用程序.fcgi：

#!...myenv/bin/python3

import os
import sys
import traceback
from flup.server import *
home = '...'
try:
    os.environ['VIRTUAL_ENV'] = os.path.join(home, '...myenv/bin/python')
    os.environ['PATH'] = os.environ['VIRTUAL_ENV'] + ':' + os.environ['PATH']

    project = os.path.join(home, 'myapp')
    # Add a custom Python path.
    sys.path.insert(0, project)

    # Switch to the directory of your project.
    os.chdir(project)

    # Set the DJANGO_SETTINGS_MODULE environment variable.
    os.environ['DJANGO_SETTINGS_MODULE'] = "myapp.settings"

    from django_fastcgi.servers.fastcgi import runfastcgi
    from django.core.servers.basehttp import get_internal_wsgi_application

    wsgi_application = get_internal_wsgi_application()
    runfastcgi(wsgi_application, method="prefork", daemonize="false", minspare=1, maxspare=1, maxchildren=1)
except:
    with open(os.path.join(home, 'tmp/error.log'), 'w') as fp:
        traceback.print_exc(file = fp)

Answer 1

Flup 与 Python3 不兼容。看起来有一个 fork，flup-py3，您应该安装它。

确实，尽管您应该考虑一个允许您使用 WSGI 的现代托管环境。
