dj-revproxy

simple reverse proxy for django project site.

Django reverse proxy. Allows you to proxy any website behind a prefix.

Requirements

Installation

Install from sources:
$ python setup.py install
Or from Pypi:
$ easy_install -U dj-revproxy

Configuration

Add revproxy to the list of applications:
INSTALLED_APPS = (
    ...
    'revproxy'
)

Usage

Since 0.2, there is 2 ways to use dj-revproxy.

1. Generic view

You can use proxy_request function to proxy any url. You can use it in your code:
proxy_request(request, "http://example.com")
This code will proxy current request to http://example.com domain. This function can take 5 parameters:
  • destination: string, the proxied url. Required
  • path: string, If no path is given it will try to detect the url using the prefix if it's given. If not full request.path will be used in finl destination url.
  • prefix: string, the prrefix behind we proxy the path headers: dict, custom HTTP headers
  • no_redirect: boolean, False by default, do not redirect to "/" if no path is given
  • decompress: boolean, False by default. If true the proxy will decompress the source body if it's gzip encoded.
It return an instance of django.http.HttpResponse. You can use it directly in your urls.py (which is the eaiest way to use). Ex:
(r'^gunicorn(?P<path>.*)', "revproxy.proxy.proxy_request", {
    "destination": "http://gunicorn.org"
}),

2. Configure multiple proxy behind one generic prefix

To configure a proxy add a tupple to the REVPROXY_SETTINGS list:
REVPROXY_SETTINGS = [
    ("_google", "http://google.com"),
    ("_friendpaste", "http://www.friendpaste.com"),
    ("_couchdb", "http://127.0.0.1:5984"),
]
Then configure your proxied urls automatically do something like this in urls.py:
from django.conf.urls.defaults import *

import revproxy.proxy

urlpatterns = patterns('',
    ...
    (r'^proxy/', include(proxy.site_proxy.urls)),
)
Which will allow you to proxy Google on the url:
http://127.0.0.1:8000/proxy/_google
or even:
('^proxy/(?P<prefix>[^\/]*)(.*)', "proxy.site_proxy"),

当然你也可用nginx做反向代理。
