An example would be:

% python curl_to_send_string.py -X POST -H "Host: api.example.com" -H "User-Agent: Custom BIG-IP Monitor" -H "Accept-Encoding: identity" -H "Connection: Close" -H "Content-Type: application/json" -d '{
  "hello":
      "world"
}
' "http://10.1.10.135:8080/post?show_env=1"
SEND STRING:
POST /post?show_env=1 HTTP/1.1\r\nHost: api.example.com\r\nUser-Agent: Custom BIG-IP Monitor\r\nAccept-Encoding: identity\r\nConnection: Close\r\nContent-Type: application/json\r\n\r\n{\n  \"hello\":\n      \"world\"\n}\n

Code :

Python 2.x

import getopt
import sys
import urllib

optlist, args = getopt.getopt(sys.argv[1:], 'X:H:d:')
flat_optlist = dict(optlist)

method = flat_optlist.get('-X','GET')

(host,uri) = urllib.splithost(urllib.splittype(args[0])[1])
protocol = 'HTTP/1.1'

headers = ["%s %s %s" %(method, uri, protocol)]
headers.extend([h[1] for h in optlist if h[0] == '-H'])
if not filter(lambda x: 'host:' in x.lower(),headers):
    headers.insert(1,'Host: %s' %(host))


send_string =  "\\r\\n".join(headers)
send_string += "\\r\\n\\r\\n"

if '-d' in flat_optlist:
    send_string += flat_optlist['-d'].replace('\n','\\n')
send_string = send_string.replace("\"", "\\\"")
print "SEND STRING:"
print send_string

Python 3.x

import getopt
import sys

from urllib.parse import splittype, urlparse

optlist, args = getopt.getopt(sys.argv[1:], 'X:H:d:')
flat_optlist = dict(optlist)

method = flat_optlist.get('-X','GET')

parts = urlparse(splittype(args[0])[1])
(host,uri) = (parts.hostname,parts.path)
protocol = 'HTTP/1.1'

headers = ["%s %s %s" %(method, uri, protocol)]
headers.extend([h[1] for h in optlist if h[0] == '-H'])
if not filter(lambda x: 'host:' in x.lower(),headers):
    headers.insert(1,'Host: %s' %(host))


send_string =  "\\r\\n".join(headers)
send_string += "\\r\\n\\r\\n"

if '-d' in flat_optlist:
    send_string += flat_optlist['-d'].replace('\n','\\n')
send_string = send_string.replace("\"", "\\\"")
print("SEND STRING:")
print(send_string)
