If http param contains blank, how to parse blank to %20, not + ?

import requests

param = {
    "sql": "project = 'foo' and name = 'bar'"

res = requests.get(

# actual    http://xxxx/?sql=project+%3D+%27foo%27+and+name+%3D+%27bar%27
# expect    http://xxxx/?sql=project%20%3D%20%27foo%27%20and%20name%20%3D%20%27bar%27

A quick dirty way to achieve that :

for x in param:
     param[x] = param[x].replace(" ","%20")

'+' or '%20', It shouldn't be an issue for you anyways

As far as I can work out, requests uses urllib.parse.urlencode.

By default, quote_plus() is used to quote the values, which means spaces are quoted as a '+' character and ‘/’ characters are encoded as %2F, which follows the standard for GET requests (application/x-www-form-urlencoded).

There seems to be a way to pass a "quote_via" parameter to the urlencode inside urllib, but that does not seem to be implemented in the requests library.

Can you explain why you would need this, as I have difficulty finding a reason for the request.
