#!/usr/bin/env python
 
import urllib
import urllib2
import json
 
url_base = "http://127.0.0.1/cgi/test"
 
#GET
try:
 query = {'test':'yes','name':'colin'}
 query_string = urllib.urlencode(query)
 url = url_base+"?"+query_string
 print "GET", url<br data-filtered="filtered"> print "web output:"
 print urllib2.urlopen(urllib2.Request(url)).read()
except Exception as err:
 print err
 
#post
try:
 url = url_base
 print "POST", url
 a = {'k1':123, 'k2': '456', 'k3':'test'}
 json_s = json.dumps(a)<br data-filtered="filtered"> print "POST input:"
 print json_s<br data-filtered="filtered"> print "web output:"
 print urllib2.urlopen(urllib2.Request(url, json_s)).read()
except Exception as err:
 print err 

#!/bin/bash
echo -e 'Content-type:text/plain\r'
echo -e '\r'
 
if [ X"$REQUEST_METHOD" = X"POST" ];then
  jq . | sed -nr '/:/!d; s/^([ \t]*"[^"]+"[ \t]*):/\1=/;s/,[ \t]*$//;s/"//g;p'
else
  echo ${QUERY_STRING} | awk 'BEGIN{RS="&"}1'
fi 

$ ./test.py
GET http://127.0.0.1/v1/lic/test?test=yes&name=colin
web output:
test=yes
name=colin


POST http://127.0.0.1/v1/lic/test
POST input:
{"k3": "test", "k2": "456", "k1": 123}
web output:
 k3= test
 k2= 456
 k1= 123
