Here's a sample GET request that retrieves an erasure coding topology named ex-corp-4. The request writes the output to a file named ex-corp-4.xml. The request is made using a system-level user account that includes the administrator role.

Request with cURL command line

curl -k -H "Accept: application/xml"
    -H "Authorization: HCP bGdyZWVu:35dc4c4aa08fe0deab7e292e00eb8e97"
    "https://admin.hcp-us.example.com:9090/mapi/services/erasureCoding/
        ecTopologies/ex-corp-4?verbose=true&prettyprint" > ex-corp-4.xml

Request in Python using PycURL

import pycurl
filehandle = open("ex-corp-4.xml", 'wb')
curl = pycurl.Curl()
curl.setopt(pycurl.HTTPHEADER, ["Accept: application/xml",
  "Authorization: HCP bGdyZWVu:35dc4c4aa08fe0deab7e292e00eb8e97"])
curl.setopt(pycurl.URL,
  "https://admin.hcp-us.example.com:9090/mapi/services/" +
  "erasureCoding/ecTopologies/ex-corp-4?verbose=true&prettyprint")
curl.setopt(pycurl.SSL_VERIFYPEER, 0)
curl.setopt(pycurl.SSL_VERIFYHOST, 0)
curl.setopt(pycurl.WRITEFUNCTION, filehandle.write)
curl.perform()
print curl.getinfo(pycurl.RESPONSE_CODE)
curl.close()
filehandle.close()
