通过请求，上传Multipart编码的文件非常简单：
with open('report.xls', 'rb') as f: r = requests.post('http://httpbin.org/post', files={'report.xls': f})而已。我不是在开玩笑-这是一行代码。文件已发送。让我们检查：
>>> r.text{ "origin": "179.13.100.4", "files": { "report.xls": "<censored...binary...data>" }, "form": {}, "url": "http://httpbin.org/post", "args": {}, "headers": { "Content-Length": "3196", "Accept-Encoding": "identity, deflate, compress, gzip", "Accept": "*/*", "User-Agent": "python-requests/0.8.0", "Host": "httpbin.org:80", "Content-Type": "multipart/form-data; boundary=127.0.0.1.502.21746.1321131593.786.1" }, "data": ""}
