如何解析通过 POST 收到的 URL 编码数据

Question

I'm writing a django webhook for a service that send data via POST that is URL encoded. Example POST show below:

POST id=a5f3ca18-2935-11e7-ad46-08002720e7b4
 &originator=1123456789
 &recipient=1987654321
 &subject=MMS+reply
 &body=View+our+logo
 &mediaUrls[0]=https://storage.googleapis.com/mms-assets/20170424/a0b40b77-30f8-4603-adf1-00be9321885b-messagebird.png
 &mediaContentTypes[0]=image/png
 &createdDatetime=2017-04-24T20:15:30+00:00

I understand how to parse json but I haven't encountered this format before. There doesn't appear to be any useful tutorials for how to handle this via POST . I'm stuck at this point so help would be greatly appreciated.

Answer 1

Python 2:

>>> from urlparse import parse_qs
>>> parse_qs('foo=spam&bar=answer&bar=42')
{'foo': ['spam'], 'bar': ['answer', '42']}

Python 3:

>>> from urllib.parse import parse_qs
>>> parse_qs('foo=spam&bar=answer&bar=42')
{'foo': ['spam'], 'bar': ['answer', '42']}

Both python 2/3:

>>> from six.moves.urllib.parse import parse_qs

UPD

There is also parse_qsl function that returns a list of two-items tuples, like

>>> parse_qsl('foo=spam&bar=answer&bar=42')
[('foo', 'spam'), ('bar', 'answer'), ('bar', '42')]

It is very suitable to passing such list to dict() constructor, meaning that you got a dict with only one value per name. Note that the last name/value pair takes precedence over early occurrences of same name (see dict in library reference).
