python中提交附件问题

Question

现在用soapUI 可以提交附件，然后请求webservice。想用python requests实现网络请求，请问附件怎么上传呢？
在SOAPUI中是这样，缓存下来提交的。

https://www.soapui.org/docs/s...

请问怎么实现用requests上传附件呢？我用这样的方法是不行的

xml_content='<?xml version="1.0"?>' \
'<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:add="http://www.w3.org/2005/03/addressing" xmlns:man="http://www.taleo.com/ws/integration/toolkit/2011/05/management">' \
'<soapenv:Header>' \

'<inc:Include xmlns:inc="http://www.w3.org/2004/08/xop/include" href="cid:large-document-generated.xml">' \
'</inc:Include>' \
'</man:Document>' \
'</man:submitLargeDocument>' \
'</soapenv:Body>' \
'</soapenv:Envelope>' #上传的soap内容

files = {'file': ('large-document-generated.xml', open(r'C:\Users\John\Desktop\large-document-generated.xml', 'rb'))}


html0=requests.post(url=url,data=result,headers=headers,files=files)

不能同时上传data和files
