Django：在中间件中用request.urlconf覆盖ROOT_URLCONF [英] Django: Overwrite ROOT_URLCONF with request.urlconf in middleware

问题描述

  from django.utils.cache import patch_vary_headers 
 
 class SubdomainMiddleware：
 def process_request（self，request）：
 path = request.get_full_path（）
 root_url = path.split（'/'）[1] 
 domain_parts = request.get_host（）。split（'。'）
 
 if（len（domain_parts）> 2）：
 subdomain = domain_parts [0] 
 if（subdomain.lower（）=='www'）：
 subdomain =无
 else：
 subdomain =无
 
 request.subdomain = subdomain 
 request.domain = domain 
 
如果request.subdomain ==api：
 request.urlconf =rest_api_example.urls。 api
 else：
 request.urlconf =rest_api_example.urls。
  

我尝试使用set_urlconf模块from django.core.urlresolve rs也不行。我在这里缺少一些东西？

解决方案

有趣的是，我使用set_urlconf模块和request.urlconf来设置url路径，现在它的工作！

从django.core.urlresolvers导入set_urlconf 
如果request.subdomain ==api：
 set_urlconf（rest_api_example.urls.api）
 request.urlconf =rest_api_example.urls.api
 else：
 set_urlconf（rest_api_example.urls.default）
请求.urlconf =rest_api_example.urls.default
  

I am trying to overwrite ROOT_URLCONF with another url when the request contains "api" subdomain and this is what I have so far.

from django.utils.cache import patch_vary_headers  

class SubdomainMiddleware:
  def process_request(self, request):
    path = request.get_full_path()  
    root_url = path.split('/')[1]
    domain_parts = request.get_host().split('.')

    if (len(domain_parts) > 2):
        subdomain = domain_parts[0]
        if (subdomain.lower() == 'www'):
            subdomain = None
    else:
        subdomain = None

    request.subdomain = subdomain 
    request.domain = domain

    if request.subdomain == "api":
        request.urlconf = "rest_api_example.urls.api"
    else:
        request.urlconf = "rest_api_example.urls.

I tried using set_urlconf module "from django.core.urlresolvers" too but it didn't work. Am I missing something here?

解决方案

Interestingly, I used set_urlconf module and request.urlconf to set url path and now it's working!

    from django.core.urlresolvers import set_urlconf
    if request.subdomain == "api":
        set_urlconf("rest_api_example.urls.api")
        request.urlconf = "rest_api_example.urls.api"
    else:
        set_urlconf("rest_api_example.urls.default")
        request.urlconf = "rest_api_example.urls.default"
