我有一个简单的PMML http://en.wikipedia.org/wiki/Predictive_Model_Markup_Language我想要的文件PUT到评分服务器。这里是curl call:
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，但我正在使用开放评分 https://github.com/jpmml/openscoringPMML 评分服务器。
我建议使用 Kenneth Reitz 的 requests 库（GitHub https://github.com/kennethreitz/requests/ and Docs http://docs.python-requests.org/en/latest/).
具体来说，有一个example http://docs.python-requests.org/en/latest/user/quickstart/#post-a-multipart-encoded-file关于如何发布文件。用它来构建你需要的东西。
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任何其他您需要的内容。 requests 使用起来非常简单，并且对 Python 社区来说是一个福音。该文档非常出色，您通常可以通过 Google/Bing/DuckDuckGo 搜索轻松找到示例。
我希望这有帮助！
