我有一个简单的PMML文件,我想将其发送PUT到评分服务器。调用如下curl:
PUT
curl
curl -X PUT --data-binary @DecisionTreeIris.pmml -H "Content-type: text/xml" http://localhost:8080/openscoring/model/DecisionTreeIris
这是 PMML 文件:

不确定这是否重要,但我正在使用Openscoring PMML 评分服务器。
我建议使用 Kenneth Reitz 的请求库(GitHub和Docs)。
具体来说,这里有一个关于如何 POST 文件的示例。使用它来构建您需要的内容。
我只是在这里假设,但我会尝试以下操作:
import requests url = 'http://localhost:8080/openscoring/model/DecisionTreeIris' files = {'file': open('/path/to/file/DecisionTreeIris.pmml', 'rb')} response = requests.post(url, files=files)
您还可以设置标题或其他任何您需要的内容。requests 使用起来非常简单,对 Python 社区来说是一个福音。文档非常出色,您通常可以通过 Google/Bing/DuckDuckGo 搜索轻松找到示例。
