How to decode a (doubly) 'url-encoded' string in python

问题

Tried decoding a url-encoded string in the following way

some_string = 'FireShot3%2B%25282%2529.png'
import urllib
res = urllib.unquote(some_string).decode()
res
u'FireShot3+%282%29.png'

Original string is FireShot3 (2).png. Any help would be appreciated.

Answer: urllib.unquote_plus(urllib.unquote_plus(some_string)) due to double encoding.

回答1:

Your input is encoded double. Using Python 3:

urllib.parse.unquote(urllib.parse.unquote(some_string))

Output:

'FireShot3+(2).png'

now you have the + left.

Edit:

Using Python 2.7 it of course is:

urllib.unquote(urllib.unquote('FireShot3%2B%25282%2529.png'))

回答2:

urllib.unquote_plus(urllib.unquote_plus(some_string)) FireShot3 (2).png
