how to pass parameters to python script as JSON
How to call below python script through API and pass the parameters through JSON?
I need help to pass the hostname, credenials details and commands as parameters from an external application.
import paramiko hostname = "127.0.0.1" username = "test" password = "abc1235" commands = [ "pwd", "id", "uname -a", "df -h" ] # initialize the SSH client client = paramiko.SSHClient() # add to known hosts client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) try: client.connect(hostname=hostname, username=username, password=password) except: print("[!] Cannot connect to the SSH Server") exit() # execute the commands for command in commands: print("="*50, command, "="*50) stdin, stdout, stderr = client.exec_command(command) print(stdout.read().decode()) err = stderr.read().decode() if err: print(err)
Using argparse
you can pass in the JSON as a command line argument and then using python’s built-in json
package, parse the JSON like so:
import argparse import json # Set up the argument parser parser = argparse.ArgumentParser() parser.add_argument('JSON', metavar='json',type=str, help='JSON to parse') args = parser.parse_args() # Get JSON data json_str = args.JSON # Parse JSON data json_data = json.loads(json_str) print(json_data["hostname"])
But honestly you’d be way better off if you just separated the JSON values and them passed each of them on individually as a command line argument.
