如何解析通过POST收到的application/x-www-form-urlencoded

问题描述

我正在为服务编写django webhook，该服务通过POST以我认为的application/x-www-form-urlencoded格式发送数据.示例POST显示如下:

I'm writing a django webhook for a service that send data via POST in what I believe is the application/x-www-form-urlencoded format. 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

我了解如何解析json，但是我之前从未遇到过这种格式.关于如何通过POST处理此问题，似乎没有任何有用的教程.我目前仍处于停滞状态，因此将不胜感激.

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.

推荐答案

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']}

两个python 2/3:

Both python 2/3:

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

UPD

还有parse_qsl函数，该函数返回两个项目元组的列表，例如

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')]

非常适合将此类列表传递给dict()构造函数，这意味着您获得的dict每个名称仅包含一个值.请注意，姓氏/值对优先于同名的早期出现(请参见 dict (在库参考中).

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).
