json - Using Python to PUT PMML -

i have simple pmml file put scoring server. here curl call:

curl -x set --data-binary @decisiontreeiris.pmml -h "content-type: text/xml" http://localhost:8080/openscoring/model/decisiontreeiris

here pmml file:

not sure matters using openscoring pmml scoring server.

i'd recommend using requests library kenneth reitz (github , docs).

specifically, there's example on how post files. utilize build need.

i'm assuming here seek following:

import requests url = 'http://localhost:8080/openscoring/model/decisiontreeiris' files = {'file': open('/path/to/file/decisiontreeiris.pmml', 'rb')} response = requests.post(url, files=files)

you can set headers or else need. requests dead simple utilize , boon python community. documentation first-class , can find examples google/bing/duckduckgo search easily.

i hope helps!
