How to use python requests to PUT a pmml model to openscoring

I'm trying to use python requests to PUT a .pmml model to a local openscoring server.
This works (from directory containing DecisionTreeIris.pmml):

curl -X PUT --data-binary @DecisionTreeIris.pmml -H "Content-type: text/xml" http://localhost:8080/openscoring/model/DecisionTreeIris

This doesn't:

import requests
file = '/Users/weitzenfeld/IntelliJProjects/openscoring/openscoring-server/etc/DecisionTreeIris.pmml'
r = requests.put('http://localhost:8080/openscoring/model/DecisionTreeIris', files={'file': open(file, 'rb')})
r.text

returns: 

u'<html>\n<head>\n<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>\n<title>Error 415 </title>\n</head>\n<body>\n<h2>HTTP ERROR: 415</h2>\n<p>Problem accessing /openscoring/model/DecisionTreeIris. Reason:\n<pre>    Unsupported Media Type</pre></p>\n<hr /><i><small>Powered by Jetty://</small></i>\n</body>\n</html>\n'

I also tried:

r = requests.put('http://localhost:8080/openscoring/model/DecisionTreeIris', files={'file': open(file, 'rb')}, headers={'Content-type': 'text/xml', 'Accept': 'text/xml'})
r.text

which returns:

u'<html>\n<head>\n<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>\n<title>Error 406 </title>\n</head>\n<body>\n<h2>HTTP ERROR: 406</h2>\n<p>Problem accessing /openscoring/model/DecisionTreeIris. Reason:\n<pre>    Not Acceptable</pre></p>\n<hr /><i><small>Powered by Jetty://</small></i>\n</body>\n</html>\n'

Note that my python attempt is the same as in the accepted answer to this question: Using Python to PUT PMML.

Also, someone with >1500 rep should consider making an 'openscoring' tag.

Solution

  • Solution was to put data, not the file handler: 

    r = requests.put('http://localhost:8080/openscoring/model/DecisionTreeIris', data=open(file, 'rb'), headers={'Content-type': 'text/xml', 'Accept': 'text/xml'})
