REST, REpresentational State Transfer

  • Transports JSON-formatted data over HTTP
  • Stateless as the server does not hold client context (history). Pre: simple, Con: sometimes more requests needed.

Example code, fetching data, session state (login information) is kept by the client.

#!/usr/bin/env python
 
import requests
import json
import sys
import urllib3
 
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
 
rest_host = "<servername>"
rest_url = "https://"+rest_host
command_url = "<filepath>"
 
post_headers = '{"Content-Type":"application/json"}'
 
def main():
    rest_session = requests.Session()
    response = rest_session.post(rest_url+"/login",
                                data={"USERNAME":<user>,"PASSWORD":<password>},
                                verify=False)
    print ("login status: "+str(response.status_code))
 
    response = rest_session.get(rest_url+command_url,verify=False,stream=True)
    print ("Command status: "+str(response.status_code))
    if response.status_code == 200:
        print(session.content)
    response = rest_session.post(rest_url+"/logout", verify=False)
    return()
 
main()
