Error in requests.post

[debanilroy]

I am making a project and for that, I am making a python program. The program uses requests.post to get access to some info. However, whenever I run it, it gives a traceback.

The error is that the remote end disconnects without response. How can I solve this problem?
I need help ASAP.

Here's the code below

import requests,re
import xml.etree.ElementTree as ET

#def getCellTowerInfo():
print ("Logging in to router home page")    
baseurl = 'http://192.168.0.1/'
url = baseurl + 'login.asp'
payload = {'ID':'admin','PASSWORD':'admin','REDIRECT':'index.asp','REDIRECT_ERR':'login.asp'}
response = requests.get(url, data = payload)

print (response)

[volcano63]

...
payload = {'ID':'admin','PASSWORD':'admin','REDIRECT':'index.asp','REDIRECT_ERR':'login.asp'}
response = requests.get(url, data = payload)
...
print (response)

• With payload, you must use post, not get.
  
• data= is used with serialized payload - either use data=json.dumps(payload) or json=payload
  
• When you login, you need to store aside session authorization. If you use
  

  session = requests.Session()
  session.post(url, ...) 

  the session object will manage that for you

Thanks for the help!!!
However, I have not been able to solve the problem still. I am a beginner python programmer and so I have little knowledge about it. However, I can understand what's happening by reading a code.

I've changed the code as per your advice. Is it how you wanted now?

import requests,re
import xml.etree.ElementTree as ET
import json
#def getCellTowerInfo():
print ("Logging in to router home page")    
baseurl = 'http://192.168.0.1/'
url = baseurl + 'login.asp'
payload = {'ID':'admin','PASSWORD':'admin','REDIRECT':'index.asp','REDIRECT_ERR':'login.asp'}
response = requests.Session()
response = response.post(url, data = json.dumps(payload) )
print (response)

On running this, the error which pops out is...

I hope you can help further.

Have you inspect login (dev-tools Chrome or FireFox),to see what happens when login?
The Form Data most be correct,and you may need a some Header data.
json.dumps(payload) is not needed Requests do serializing automatic as this is build in.

With login there are many different methods and it easy to get stuck.
Requests doc Authentication has some about basic ones,eg Digest, OAuth 1 and 2,OpenId ect...

If i want to log in into this site.

import requests
from bs4 import BeautifulSoup

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36'
}

params = {
    "username": "user_name",
    "password": "xxxxxxxxx",
    "remember": "yes",
    "submit": "Login",
    "action": "do_login",
}

with requests.Session() as s:
    s.post('https://python-forum.io/member.php?action=login', headers=headers, params=params)
    # logged in! cookies get saved for future requests
    response = s.get('https://python-forum.io/index.php')
    # cookies sent automatically!
    soup = BeautifulSoup(response.content, 'lxml')
    welcome = soup.find('span', class_="welcome").text
    print(welcome)
