Json and requests in python

Question

import requests
import json

url = 'mywebsite/test.php'
myobj = data = {"username" : "test", "password" : "1234"}


myobj = json.dumps(myobj)
x = requests.post("loginUser",url, data = myobj)

print(x)

I get the following error:

Traceback (most recent call last):
File "main.py", line 55, in <module> x = requests.post("loginUser",url, data = myobj) TypeError: post() got multiple values for argument 'data'

Can anyone help with this?

The call signature is requests.post(url, data=None, json=None, **kwargs). You use "loginUser" as the url, and your url as data, so double data. What is your intent for "loginUser"? What is it supposed to do? — tdelaney

It is the method I am trying to call in my php script I am connecting to — jeffinter

That will depend on how your test.php is written. My guess is that requests.post(url, data = myobj) will work - assuming that your test.php hard codes the call to loginUser. — tdelaney

I am so sorry but I just figured out that I used the wrong terminology when saying that loginUser was a method. I should have said it was a function. — jeffinter

Look at the docs:

https://docs.python-requests.org/en/latest/api/

requests.post(url, data=None, json=None, **kwargs)[source]
Sends a POST request.

Parameters: 
url – URL for the new Request object.
data – (optional) Dictionary, list of tuples, bytes, or file-like object to send in the body of the Request.
json – (optional) json data to send in the body of the Request.
**kwargs – Optional arguments that request takes.
Returns:    
Response object

and so your command should be:

myobj = json.dumps(myobj).encode("ascii")
x = requests.post(url = url, data = myobj)

or without using json.dumps:

x = requests.post(url = url, json = myobj)

What exactly is "loginUser" for in this case? is that a URI route, field, or parameter?

I'm just learning python myself and have used requests a bit.

I've always put the url at the beggining and payload at the end:
i.e Should "LoginUser" go at the end?

I have fixed it. Problem was that I didn’t put http:// in front of the url and I didn’t format my JSON request the way my php was expecting.
