To make POST request instead of GET request using urllib2  you need to specify empty data  for example   import urllib2 req   urllib2 Request  http   am domain com 8080 openam json realms root authenticate authIndexType Module amp authIndexValue LDAP   req add header  X-OpenAM-Username    demo   req add data     r   urllib2 urlopen req

If we want to add custom HTTP headers to a POST request  we must pass them through a dictionary to the headers parameter   Here is an example with a non-empty body and headers   import requests import json  url    https   somedomain com  body     name    Maryja   headers     content-type    application json    r   requests post url  data json dumps body   headers headers    Source
