Python 3.6 - Can't convert Unicode in a string

问题

I am doing some scraping work with Python 3.6 and retrieved some URLs in strings following this format:

someURL = 'http:\u002F\u002Fsomewebsite.com\u002Fsomefile.jpg'

I have been trying to convert the Unicode backslash (\u002F) in those strings in order to use the URLs (using regex methods, encode() on the strings, etc.), to no avail. The string still keeps the Unicode backslash and, if I pass it on to Requests' get(), for example, I am greeted by the following error message:

InvalidURL: Failed to parse: http:\u002F\u002Fsomewebsite.com\u002Fsomefile.jpg"

I searched for solutions in this forum and and others, but can't seem to put the finger on it. I am sure it is simple...

回答1:

Use codecs.decode with the encoding named 'unicode-escape':

import codecs
print(codecs.decode(someURL, 'unicode-escape'))
# prints 'http://somewebsite.com/somefile.jpg'
