Write the Logic of your Program in main()

In your main() method, read the value of the domain passed in by the user. Then obtain the IP address for the domain. Finally, obtain the data about the domain from the Shodan API.

Once you have the details of the domain, print the information about the CPEs and the hostnames to the screen.

If your program encounters an error either in resolving the domain or obtaining information from the API, write a simple error message to the screen and end the program.

Commit and Branch!

Once you have tested your index.py script, do the following:

Add and commit your files using Git
Remember to add the standard Python .gitignore file!
(Optional) Push all your branches to GitHub.com with the command git push origin –all

test your code with these commands

python index.py -d purdue.edu
python index.py -d blah

here is the instuction

The first command should bring back information about the CPEs on the Purdue website and the (long) list of hostnames associated with that domain.

The second command should fail gracefully, as there is no domain named “blah”

here is the code

import argparse

import requests

import socket

import json

def get_ip_address(domain):

try:

ip_address = socket.gethostbyname(domain)

return ip_address

except socket.error as e:

print(f"Error resolving domain: {e}")

return None

def shodan_api_request(api_key, ip_address):

base_url = "https://api.shodan.io/shodan/host/"

try:

# Make the API request with the correct key

response = requests.get(f"{base_url}{ip_address}?key={api_key}")

response.raise_for_status()

# Check for Forbidden status (HTTP 403)

if response.status_code == 403:

print("API key does not have permission to access this resource.")

return None

return response.json()

except requests.exceptions.RequestException as e:

print(f"Error in Shodan API request: {e}")

return None

def main():

parser = argparse.ArgumentParser(description="Retrieve information about a domain from Shodan.")

parser.add_argument("-d", "--domain", required=True, help="Domain to look up")

args = parser.parse_args()

domain = args.domain

# Replace 'your_actual_api_key_here' with your actual Shodan API key

shodan_api_key = 'mIanS6wnOSmZuiUvuyXq4nMWCXQmoVNZ'

ip_address = get_ip_address(domain)

if ip_address:

shodan_data = shodan_api_request(shodan_api_key, ip_address)

if shodan_data:

cpe_info = shodan_data.get("data", [])

hostnames = shodan_data.get("hostnames", [])

print("\nHostnames:")

for hostname in hostnames:

print(hostname)

else:

print("No data received from Shodan API.")

else:

print("Exiting program due to previous error.")

if __name__ == "__main__":

main()

please fix it cpe and take a look a picture what I attached it should display like it.
