python – Django_Hosts导入错误

2019年8月3日 124次阅读

我想要做的是让网站重定向到www(例如“example.com”到“www.example.com”)

我使用pip来安装django_hosts,然后按照网站上的文档进行操作

这是我的settings.py文件：

"""

这是我的hosts.py文件：

from django.conf import settings
from django_hosts import patterns, host

host_patterns = patterns('',
    host(r'www', settings.ROOT_URLCONF, name='www'),
    #host(r'(\w+)', 'path.to.custom_urls', name='wildcard'),
)

当我运行python manage.py runserver时,我收到以下错误：

django.core.exceptions.ImproperlyConfigured：无法加载WSGI应用程序’mysite.wsgi.application’;导入模块时出错：’没有名为’django_hosts.middleware.HostsRequestMiddlewaredjango’的模块; ‘django_hosts.middleware’不是包’

我究竟做错了什么？！

最佳答案 你错过了一个逗号：

MIDDLEWARE_CLASSES = [
    'django_hosts.middleware.HostsRequestMiddleware', # <-----
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
