python解码非英语用作URL？

Question

I have a variable such as title :

title = "révolution_essentielle"

I could encode and decode it like this for other purposes:

title1 = unicode(title, encoding = "utf-8")

But how do I preserve the Non-English and use it as part of a url string to access the url? For instance, I ideally want https://mainurl.com/révolution_essentielle.html by concatenating several strings including title like this:

url = main_url + "/" + title + ".html"

Could anyone kindly show me how to do that? Thanks a bunch!

Answer 1

To summarize what we've talked about in the comments: there is a function for quoting URLs (replacing special characters with % prefix escape sequences.

For Python 2 (as used in this case), it's urllib.quote() , which can be used as follows:

urllib.quote("révolution_essentielle")

When our input is an unicode object with wide characters, we need to also encode it first, eg:

urllib.quote(u'hey_there_who_likes_lego_that\xe3\u019\xe2_\xe3_...'.encode('utf8')).

Be ware though so that your representation matches the one expected/understood by the counterpart machine.

If we were talking Python 3, the equivalent function would be urllib.parse.quote() :

urllib.parse.quote("révolution_essentielle")

Which can chew over str (unicode) parameters as well as encoded value in bytes object.
