我使用自定义模板标记。例如:<your_app>/templatetags/site.py:

# -*- coding: utf-8 -*-
from django import template
from django.contrib.sites.models import Site

register = template.Library()

@register.simple_tag
def current_domain():
    return 'http://%s' % Site.objects.get_current().domain

在模板中使用它，就像这样:

{% load site %}
{% current_domain %}

这种方法怎么样?对我有用。 它也用于django注册。

def get_request_root_url(self):
    scheme = 'https' if self.request.is_secure() else 'http'
    site = get_current_site(self.request)
    return '%s://%s' % (scheme, site)

我认为你想要的是访问请求上下文，参见RequestContext。

我认为我们想要的是现有url标签的替代品，所以我写了一个新标签:

from django.template import Library
from django.urls     import reverse

@register.simple_tag(takes_context = True)
def fullURL(context, name, *args, **kwargs):
    request = context['request']
    return f'{request.scheme}://{request.get_host()}{reverse(name, args = args, kwargs = kwargs)}'

然后在你的模板中你可以这样…

{% extends "myapp/email/email_base.html" %}

{% load mytags %} {# Replace mytags with whatever the name of your custom tags calss is. #}

{% block content %}
<p>You can use <a href="{% fullURL 'signup' %}">this link</a> to get started with your account. We look forward to seeing you soon!</p>
{% endblock content %}

然后，当你生成这个时，你只需要记住将请求传递到上下文，就像这样……

from django.template.loader import render_to_string

def sendEmail(subject, to, template, **context):
    html = render_to_string(f'myapp/email/{template}.html', context | {'subject': subject})
    # ... and so on with the rest of my function for sending email...

您可以在模板中使用{{protocol}}://{{domain}}来获取您的域名。

下面这些可以获得完整的url和部分url:

def myview(request):
    request.build_absolute_uri()
    # http://localhost:8000/admin/store/product/

    request.build_absolute_uri('/')
    # http://localhost:8000/

    request.build_absolute_uri('/')[:-1]
    # http://localhost:8000

    request.scheme
    # http

    request.META['HTTP_HOST']
    # localhost:8000

    request.path    
    # /admin/store/product/
