Python requests - correct way to send query-string for POST

Question

Here is what I want to be sent:

https://dev.xxx.com/employee-service/login?email=apitester@xxx.com&password=xxx!xxx

Body:
{
<JSON>
}

Here is how I send it.

Why I didn't use a dictionary for params

Because when I did, the @ in the email and the ! in the password got encoded.

    params = 'email=' + l_email + '&password=' + l_password
    l_response = requests.post(url=url, data=params, json=body, headers={'Content-Type': 'text/plain'}, verify=False)

What I got

        }
    ],
    "message": "Validation failed for object='systemUserLogin'. Error count: 4",
    "path": "/employee-service/login"
}

How can I fully debug what really got sent?

What I did find was:

l_response.request.body

# email=apitester@xxx.com&password=xxx!xxx

My conclusion is that I am definitely not sending the query-string correctly.

What am I doing wrong?

What else I tried

It goes all wrong if I set the url argument to https://dev.xxx.com/employee-service/login?email=apitester@xxx.com&password=xxx!xxx: many errors, re-tries, SSL exceptions, etc.

Answer 1

As commented, this worked.

I will close this item.

l_response = s.post(url=url+'?locationId=110', json=user_json, verify=False, headers={'Content-Type': 'application/json'})
