Python을 사용하여 PMML 넣기

Question

간단한 PMML 파일을 가지고 있는데 점수 서버에 PUT을 보내고 싶습니다. 그것은 중요하지만 난 Openscoring PMML 득점 서버를 사용하고

확실하지 않음 것을 :

여기

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

가 PMML 파일입니다 : 여기에 curl 호출입니다.

Answer 1

Kenneth Reitz (GitHub 및 Docs)의 요청 라이브러리를 사용하는 것이 좋습니다.

특히, 파일을 POST하는 방법은 example입니다. 그것을 사용하여 필요한 것을 구성하십시오.

난 그냥 여기에 있으리라 믿고있어하지만 난 다음을 시도 할이 :

import requests 

url = 'http://localhost:8080/openscoring/model/DecisionTreeIris' 
files = {'file': open('/path/to/file/DecisionTreeIris.pmml', 'rb')} 

response = requests.post(url, files=files) 

당신은 또한 당신이 필요로하는 헤더 또는 다른 어떤을 설정할 수 있습니다. 요청은 사용하기 쉽고 파이썬 공동체에 이익이됩니다. 설명서가 우수하며 대개 Google/Bing/DuckDuckGo 검색을 통해 예제를 쉽게 찾을 수 있습니다.

도움이 되었기를 바랍니다.
