Hi

I am trying to send Data to a website through "http" using
"urllib.request" library using the bellow code.
Response status code contains. 200 (OK) but Response contains
nothing...

With same data When I test using C# it working fine.. Response
having.. some data in xml format.
But I am using below python code i am getting response only "<HTML></
HTML>".

Is there any in my code..

req = urllib2.Request(url) // url is valid url
req.add_header('Authorization','AuthSub token="xxxxxxxxxxxxx"')
req.add_header('Content-Type','application/atom+xml')
req.data=data // data is having valid xml data
r = urllib2.urlopen(req)

print(r.code) // output 200
print(r.msg) // output OK
print(r.read()) //<HTML></HTML>

This does not mean you are doing it identical to C# here, doesn't it?
Also you might be looking at the defaults in the calls within C#
and some weird expectations on server side.

Also you are requesting XML by sending a payload of XML data,
so you need to make sure you actually use POST and not GET.

I'd start by watching your working application with
strace or wireshark and compare with the data to and fro
from your python application.

Also I believe there should be example code for reading
RSS feeds from python.

No it doesn't, you say so later: it contains a set of bare <HTML></HTML>
tags. That's not the same as nothing.

This is not your real code.

>>> import urllib2

>>> req = urllib2.Request(url) // url is valid url

File "<stdin>", line 1

req = urllib2.Request(url) // url is valid url

^
SyntaxError: invalid syntax

How do you expect us to find bugs in your code when you don't show us
your real code? Are we supposed to be mind-readers?

Try using the same user-agent string as your C# code uses, and see if the
server changes what it sends.
