HttpRequest.get_host() [source]
Returns the originating host of the request using information from the HTTP_X_FORWARDED_HOST (if USE_X_FORWARDED_HOST is enabled) and HTTP_HOST headers, in that order. If they don’t provide a value, the method uses a combination of SERVER_NAME and SERVER_PORT as detailed in PEP 3333.
Example: "127.0.0.1:8000"
Note
The get_host() method fails when the host is behind multiple proxies. One solution is to use middleware to rewrite the proxy headers, as in the following example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | from django.utils.deprecation import MiddlewareMixinclass MultipleProxyMiddleware(MiddlewareMixin): FORWARDED_FOR_FIELDS = [ 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED_HOST', 'HTTP_X_FORWARDED_SERVER', ] def process_request(self, request): """ Rewrites the proxy headers so that only the most recent proxy is used. """ for field in self.FORWARDED_FOR_FIELDS: if field in request.META: if ',' in request.META[field]: parts = request.META[field].split(',') request.META[field] = parts[-1].strip() |
This middleware should be positioned before any other middleware that relies on the value of get_host() – for instance, CommonMiddleware or CsrfViewMiddleware.
