Python requests doesn't add query string via params in get method-CodePudding

When I try to send GET request to a specific URL with python requests library, I get an error because requests lib does not make query string from params parameter in requests.get method and does not add that query string to the URL. But when I do exactly the same thing to another URL and put to params anything else, everything works as expected.

There is my code and output:

In [1]: import requests

In [2]: r = requests.get('https://bitmex.com/api/v1/user/margin', params={'currency': 'all'})

In [3]: r.request.url
Out[3]: 'https://www.bitmex.com:443/api/v1/user/margin'

In [4]: r = requests.get('https://google.com/bla/bla', params={'a': 1})

In [5]: r.request.url
Out[5]: 'https://google.com/bla/bla?a=1'

What you're seeing is the result of a redirect. Have a look at the Redirection and History chapter from the requests documentation. If you want the original URL, use either the allow_redirects parameter or r.history
