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
