A URL shortening app for Django.

django-url-shortening

A custom URL shortening app for Django with API.

Usage

1. Add urlshortening app to your INSTALLED_APPS and do migrate

2. Wire up the redirect view by adding to your URLconf

   ('^linkshortening/', include('urlshortening.urls'))

3. Add settings (more about parameters further)

   INITIAL_URL_LEN = 6
   RETRY_COUNT = 5
   SHORT_URL_PATH = 'http://example.com/short-prefix/'
   REDIRECT_PREFIX = 'r'

4. Now you can use API to make short links

   POST linkshortening/short/

   With json data {"full_url": "http://example.com/a/b/c/d/e"}

   And get response

   {"data": {
       "short_id": "123456",
       "short_url_path": "http://example.com/short-prefix/"
    }, "error": ""}

5. You could also use urlshortening right from code

   from urlshortening.models import get_short_url, invalidate_url, get_full_url

   url = "http://example.com/a/b/c/d/e"
   short_url = get_short_url(url) # Url object
   print(short_url.short_id) # id for short url

   full_url = get_full_url(short_url.short_id) # Url object
   print(full_url.url) # "http://example.com/a/b/c/d/e"

   # You could also invalidate url
   invalidate_url(full_url.short_id)
