有了解python的吗？这个node的等效代码怎么写？

主要是文件不知道怎么附加到参数中?

r = requests.post(api_url,sign_parameter,files=request._file_params, timeout=self._timeout)

完整的文件https://gist.github.com/ckvv/d0e4d114471ebdaae209f92534481d5a#file-lazada-py-L164

client = lazop.LazopClient(url, appkey ,appSecret)
request = lazop.LazopRequest('/marketing/rta/material/upload')
request.add_api_param('member_id', '111')
request.add_file_param('file',open('/Users/IopSdk.py').read())
response = client.execute(request)
print(response.type)
print(response.body)
