[FIXED] Retrieving parameters from a URL

Issue

Given a URL like the following, how can I parse the value of the query parameters? For example, in this case I want the value of some_key .

/some_path?some_key=some_value'

I am using Django in my environment; is there a method on the request object that could help me?

I tried using self.request.get('some_key') but it is not returning the value some_value as I had hoped.

Solution

This is not specific to Django, but for Python in general. For a Django specific answer, see this one from @jball037

Python 2:

import urlparse

url = 'https://www.example.com/some_path?some_key=some_value'
parsed = urlparse.urlparse(url)
captured_value = urlparse.parse_qs(parsed.query)['some_key'][0]

print captured_value

Python 3:

from urllib.parse import urlparse
from urllib.parse import parse_qs

url = 'https://www.example.com/some_path?some_key=some_value'
parsed_url = urlparse(url)
captured_value = parse_qs(parsed_url.query)['some_key'][0]

print(captured_value)

parse_qs returns a list. The [0] gets the first item of the list so the output of each script is some_value

Here's the 'parse_qs' documentation for Python 3
