I am sending the second string via post (JavaScript) to my bootle server (Python):

query = {
'wiki': 'Tr%E1%BA%A7n_H%C6%B0ng_%C4%90%E1%BA%A1o',
'uid':'f17afd66aae3a'
}

$.post(url, query, function(data, status){}):

But when I print what I get from the post it gives the following result:

b'uid=f17afd66aae3a&wiki=Tr%25E1%25BA%25A7n_H%25C6%25B0ng_%25C4%2590%25E1%25BA%25A1o' - First print

In the case I make two split transforming this binary string into a dictionary through the function translate(postdata) .

{'uid': 'f17afd66aae3a', 'wiki': 'Tr%25E1%25BA%25A7n_H%25C6%25B0ng_%25C4%2590%25E1%25BA%25A1o'} - Second print

And as my code will access the wikipedia article with such name:

https://en.wikipedia.org/wiki/Tr%E1%BA%A7n_H%C6%B0ng_%C4%90%E1%BA%A1o

I can not access it because my request has the following url:

https://en.wikipedia.org/wiki/Tr%25E1%25BA%25A7n_H%25C6%25B0ng_%25C4%2590%25E1%25BA%25A1o

That generates an error because the page does not exist.

There's my code in the bottle:

@post('/update_article')                                                        
@enable_cors                                                                    
def update_article_post():                                       
    token = request.cookies.get('token', '0')                                   
    if load_token(token):                                                       
        postdata = request.body.read()
        print(postdata)                                        
        dici = translate(postdata)                                              
        print(dici)                                                             
       # res = update_article(dici['uid'], dici['wiki'])                        
       # return {'data': res}                                                   
    else:                                                                       
         return redirect('/login.html')

Is there any way to get the post the right way, or code this string?

try base64 encoding

In the Python server try to decode the string before playing on the wiki, use the Python b64decode

import base64
Request = 'cmVzcG9zdGEgZGVjb2RpZmljYWRhIA==' 
resposta = base64.b64decode(Request)
print(resposta)

the output will be

According to the Bottle documentation you can access parameters received from a POST using request.forms.get('campo') .

So your question looks like it can be solved with the code:

wiki = request.forms.get('wiki')

If the Bottle does not auto-decode the string you can use the urlli.parse.unquote() .

from urllib.parse import unquote

print(unquote('Tr%25E1%25BA%25A7n_H%25C6%25B0ng_%25C4%2590%25E1%25BA%25A1o'))
