how to convert curl command line to pycurl code

Question

Here is my Original code

import urllib, urllib2
from xml.dom import minidom

base_url = 'test.com:8000'
username = 'MyId'
password = 'passwd'
search_query = 'search error | head 10'

# Login and get the session key
request = urllib2.Request(base_url + '/servicesNS/MyId/search/auth/login', 
data = urllib.urlencode({'username': username, 'password': password}))

server_content = urllib2.urlopen(request)

session_key = minidom.parseString(server_content.read()).\
getElementsByTagName('sessionKey')[0].childNodes[0].nodeValue
print "Session Key: %s" % session_key 

# Perform a search
request = urllib2.Request(base_url + '/servicesNS/MyId/search/search/jobs/export', 
data = urllib.urlencode({'search': search_query,'output_mode': 'json'}),
headers = { 'Authorization': ('Splunk %s' %session_key)})
search_results = urllib2.urlopen(request)
print search_results.read()

It causes an 404 error so I decided to use Curl.

I have this curl commend

  curl -k -u myID:Passwd -d 'search="google.com | head 10"' -d "output_mode=json" https://test.com:8089/servicesNS/myId/search/search/jobs/export

I am trying to use pycurl to call Joson.

How do I convert it to pycurl?

Thank you in advance.

Why doesn't your base_url start with 'http://'? And which of the two requests 404s? — millimoose

your urllib2 code and the curl command do not match: different ports, different requests. ElementTree provides nicer xml api: session_key = etree.parse(server_content).findtext(".//sessionKey") — jfs

Have you read the pycurl tutorial, examples, and related docs on the home page? If so, what part are you stuck on? If not… go read it and come back when you can answer the previous question. — abarnert

The best way to convert a curl command line to anything that uses libcurl (like pycurl or other bindings), is to run the command line with "--libcurl output.c" appended to it, and then you check out that created embryo as it then shows what curl had to do.

Converting that C code to pycurl code is usually trivial.
