SoapClient::SoapClient::addDefaultHeaders ( hash h )

adds default headers to each request; these headers will be sent in all requests but can be overridden in requests as well

Example:: 1 # disable gzip and bzip encoding in responses

2 soap.addDefaultHeaders(("Accept-Encoding": "compress"));

Parameters

h	a hash of headers to add to the default headers to send on each request

Note: default headers can also be set in the constructor

See Also: SoapClient::getDefaultHeaders()

Since: SoapClient 0.2.4

any SoapClient::SoapClient::call	(	string	operation,
		any	args,
		*hash	header,

wsdl_file: a path to use to load the WSDL and create the WebService object
url: override the target URL given in the WSDL
send_encoding: a send data encoding option or the value "auto" which means to use automatic encoding; if not present defaults to no content-encoding on sent message bodies
content_encoding: for possible values, see EncodingSupport; this sets the send encoding (if the "send_encoding" option is not set) and the requested response encoding
[service]: in case multiple service entries are found in the WSDL, give the one to be used here
[port]: in case multiple port entries are found in the WSDL, give the one to be used here
