With all the helpful libraries out there, you'd think Python would have an easier way of doing this!
Using urlparse() to get the ParseResult object only allows read-only access to the attributes, making it useless if you want to set the query field.
This solution comes from Ned Batchelder from StackOverflow. I found this to be much more useful than the stuff in urlparse and urllib libraries.
Create a helper class:
To get an idea of what's what:
txt = "https://gist.github.com/twig/d42c4ec9ecc5eccf3614#file-python-pil-exif-reader-py-L12"
url = Url(txt)
print "original", txt
print "scheme", url.scheme
print "domain", url.domain
print "path", url.path
print "args", url.args
print "params", url.params
print "query", url.query
print "query_string", url.query_string
print "fragment", url.fragment
print "URL", url.url
print "str", str(url) Prints out:
original: https://gist.github.com/twig/d42c4ec9ecc5eccf3614?q=url&l=python#file-python-pil-exif-reader-py-L12
scheme: https
domain: gist.github.com
path: /twig/d42c4ec9ecc5eccf3614
params:
args: {'q': 'url', 'l': 'python'}
query: q=url&l=python
query_string: ?q=url&l=python
fragment: file-python-pil-exif-reader-py-L12
URL: https://gist.github.com/twig/d42c4ec9ecc5eccf3614?q=url&l=python#file-python-pil-exif-reader-py-L12
str: https://gist.github.com/twig/d42c4ec9ecc5eccf3614?q=url&l=python#file-python-pil-exif-reader-py-L12
To make changes, just use like this:
u = Url(url)
del u.query['page']
print u.url *update 23/08/2011*
- Removed the use of urllib.urlencode() because it's deprecated. Now uses urllib.
- Added __str__() to accompany __unicode__(). Added build() method.
- Renamed args to be query.
*update 11/11/2014*
- Cleaned up the code a bit
- Added Url.url and Url.query_string attributes
- Updated comments
- Renamed Url.netloc to Url.domain
- Now supports Url and Django's HttpRequest objects in __init__()
