Member Function Documentation

◆ addDefaultHeaders()

SoapClient::SoapClient::addDefaultHeaders ( hash< auto > h )

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

Example:: # disable gzip and bzip encoding in responses

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

◆ call() [1/3]

auto SoapClient::SoapClient::call	(	reference	info,
		string	operation,
		auto	args,
		*hash< auto >	soap_header,
		*hash< auto >	http_header
	)

makes a server call with the given operation and arguments and returns the deserialized result with an output argument giving technical information about the call

Parameters

info	an optional reference to return a hash of technical information about the SOAP call (raw message info and headers); the following keys are present in this hash: `"headers"`: a hash of HTTP request headers `"request-uri"`: the request URI string (ex: `"POST /services/Soap/c/29.0 HTTP/1.1"`) `"response-uri"`: the response URI string (ex: `"HTTP/1.1 200 OK"`) `"charset"`: the character encoding string (ex: `"UTF-8"`) `"body-content-type"`: the `Content-Type` of the response without any `charset` declaration `"accept-charset"`: the valus of any `Accept-Charset` header in the response `"response-headers"`: a hash of HTTP response headers `"response-body"`: the raw XML response body (in case content encoding is used, this is the decoded value) `"request-body"`: the raw XML request body `"request-soap-headers"`: an optional hash of SOAP headers used in the request (if applicable)
operation	the operation name for the SOAP call
args	the arguments to the SOAP operation
soap_header	optional soap headers (if required by the operation)
http_header	a hash giving HTTP header information to include in the message (does not override automatically-generated SOAP message headers)

Returns: the deserialized result of the SOAP call to the SOAP server

Exceptions

WSDL-OPERATION-ERROR	the operation is not defined in the WSDL
WSDL-BINDING-ERROR	the binding is not assigned to a SOAP operation in the WSDL
HTTP-CLIENT-RECEIVE-ERROR	this exception is thrown when the SOAP server returns an HTTP error code; if a SOAP fault is returned, then it is deserialized and returned in the arg key of the exception hash

See also: SoapClient::callOperation()

Note

this method can throw any exception that HTTPClient::send() can throw as well as any XML parsing errors thrown by parse_xml()
it's recommended to use callOperation() instead, which was a cleaner and more extensible API

There are keys 'reason' with value 'request', 'response' or 'error',: 'header' (HTTP headers, as received from the remote) and 'body' containing XML data in readable form, i.e. uncompressed, and, in case of a multipart message, only the related part is passed. Method is executed before message is sent or after has been received. Do not allow exception raising in method not to interrupt client function.

Example:: private nothing msglog(hash<auto> msg) {

log(sprintf("%s:\n%s\n", msg.reason, msg.body));

}

Since: SoapClient 0.2.5

See also

Since: SoapClient 0.2.4

◆ setSendEncoding()

SoapClient::SoapClient::setSendEncoding ( string enc = 'auto' )

change the data content encoding (compression) option for the object; see EncodingSupport for valid options

Example:: sc.setSendEncoding("gzip");

The default is to send requests unencoded/uncompressed.

Parameters

enc	the data content encoding (compression) option for the object; see EncodingSupport for valid options; if the value `"auto"` is passed then `"gzip"` encoding is used
