python - Django:在中间件中用request.urlconf覆盖ROOT_URLCONF

Question

当请求包含“api”子域时，我试图用另一个 url 覆盖 ROOT_URLCONF，这是我目前所拥有的。

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.

我也尝试使用“来自 django.core.urlresolvers”的 set_urlconf 模块，但它没有用。我在这里遗漏了什么吗？

有趣的是，我使用了 set_urlconf 模块和 request.urlconf 来设置 url 路径，现在它可以工作了!

    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"
