只需直接发送xml字节即可：
#!/usr/bin/env python2# -*- coding: utf-8 -*-import requestsxml = """<?xml version='1.0' encoding='utf-8'?><a>б</a>"""headers = {'Content-Type': 'application/xml'} # set what your server acceptsprint requests.post('http://httpbin.org/post', data=xml, headers=headers).text输出量
{ "origin": "x.x.x.x", "files": {}, "form": {}, "url": "http://httpbin.org/post", "args": {}, "headers": { "Content-Length": "48", "Accept-Encoding": "identity, deflate, compress, gzip", "Connection": "keep-alive", "Accept": "*/*", "User-Agent": "python-requests/0.13.9 CPython/2.7.3 Linux/3.2.0-30-generic", "Host": "httpbin.org", "Content-Type": "application/xml" }, "json": null, "data": "<?xml version='1.0' encoding='utf-8'?>n<a>u0431</a>"}
