多个域-一个Django项目

Question

我想在多个域/网站上运行一个django项目。 每个网站都需要访问唯一的“ urls.py” /“ views.py”。 我已经在本教程中尝试过，但是对我来说不起作用。 有没有一种简便的方法（没有Sites框架）使用中间件来做到这一点？ 一点帮助将是非常不错的。 谢谢。

编辑：当我像上面的教程中那样尝试时，我的httpd.conf看起来像这样：

ServerRoot "/home/webfactionusername/webapps/erdbeer/apache2"

LoadModule authz_core_module modules/mod_authz_core.so
LoadModule dir_module        modules/mod_dir.so
LoadModule env_module        modules/mod_env.so
LoadModule log_config_module modules/mod_log_config.so
LoadModule mime_module       modules/mod_mime.so
LoadModule rewrite_module    modules/mod_rewrite.so
LoadModule setenvif_module   modules/mod_setenvif.so
LoadModule wsgi_module       modules/mod_wsgi.so
LoadModule unixd_module      modules/mod_unixd.so

    WSGIScriptAlias / /home/webfactionusername/webapps/erdbeer/subdomain1.wsgi
</VirtualHost>

    WSGIDaemonProcess erdbeer processes=5 python-path=/home/webfactionusername/webapps/erdbeer:/home/webfactionusername/webapps/erdbeer/lib/python2.7 threads=1
    WSGIScriptAlias / /home/webfactionusername/webapps/erdbeer/subdomain2.wsgi
</VirtualHost>

Edit2：我仍然无法掌握这个中间件概念。 我只能理解使用“ process_request”可能需要的方式，但是我不知道中间件文件的外观。 假设我有“ domain1.com”和“ domain2.com”，它们应使用以下网址：

domain1_urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.http import HttpResponse

urlpatterns = [
    url(r'^$', 'myapp1.views.home'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^robots\.txt$', lambda r: HttpResponse("User-agent: *\nDisallow:", content_type="text/plain")),
]

domains2_urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.http import HttpResponse

urlpatterns = [
    url(r'^$', 'myapp2.views.home'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^robots\.txt$', lambda r: HttpResponse("User-agent: *\nDisallow:", content_type="text/plain")),
]

我将如何在中间件中使用它？ （我是初学者...）

我在这里找到了完美的解决方案。

# File: settings.py

HOST_MIDDLEWARE_URLCONF_MAP = {
    # Control Panel
    "www.example.com": "webapp.sites.example.urls",
}

和

# File: multihost.py

import time
from django.conf import settings
from django.utils.cache import patch_vary_headers

class MultiHostMiddleware:

    def process_request(self, request):
        try:
            request.META["LoadingStart"] = time.time()
            host = request.META["HTTP_HOST"]
            #if host[-3:] == ":80":
            #    host = host[:-3] # ignore default port number, if present

            # best way to do this.
            host_port = host.split(':')
            if len(host_port)==2:                    
                host = host_port[0] 

            if host in settings.HOST_MIDDLEWARE_URLCONF_MAP:
                request.urlconf = settings.HOST_MIDDLEWARE_URLCONF_MAP[host]
                request.META["MultiHost"] = str(request.urlconf)
            else:
                request.META["MultiHost"] = str(settings.ROOT_URLCONF)

        except KeyError:
            pass # use default urlconf (settings.ROOT_URLCONF)

    def process_response(self, request, response):
        if 'MultiHost' in request.META:
            response['MultiHost'] = request.META.get("MultiHost")

        if 'LoadingStart' in request.META:
            _loading_time = time.time() - int(request.META["LoadingStart"])
            response['LoadingTime'] = "%.2fs" % ( _loading_time, )

        if getattr(request, "urlconf", None):
            patch_vary_headers(response, ('Host',))
        return response
