The client automatically sets the Content-Type and<br>

service: atom.<a href="#AtomService">AtomService</a> <a href="__builtin__.html#object">object</a> which contains some of the parameters <br>
needed to make the request. The following members are used to <br>
construct the HTTP call: server (str), additional_headers (dict), <br>
port (int), and ssl (bool).<br>
operation: str The HTTP operation to be performed. This is usually one of<br>
'GET', 'POST', 'PUT', or 'DELETE'<br>
data: ElementTree, filestream, list of parts, or other <a href="__builtin__.html#object">object</a> which can be <br>
converted to a string. <br>
Should be set to None when performing a GET or PUT.<br>
If data is a file-like <a href="__builtin__.html#object">object</a> which can be read, this method will read<br>
a chunk of 100K bytes at a time and send them. <br>
If the data is a list of parts to be sent, each part will be evaluated<br>
and sent.<br>
uri: The beginning of the URL to which the request should be sent. <br>
Examples: '/', '/base/feeds/snippets', <br>
'/m8/feeds/contacts/default/base'<br>
extra_headers: dict of strings. HTTP headers which should be sent<br>
in the request. These headers are in addition to those stored in <br>
service.additional_headers.<br>
url_params: dict of strings. Key value pairs to be added to the URL as<br>
URL parameters. For example {'foo':'bar', 'test':'param'} will <br>
become ?foo=bar&test=param.<br>
escape_params: bool default True. If true, the keys and values in <br>
url_params will be URL escaped when the form is constructed <br>
