Detailed Description

class to call the system REST API from the client library

Member Function Documentation

autoSetUrl()

OMQ::Client::QorusSystemRestHelper::autoSetUrl ( *hash< auto >  opts )

private

sets the URL automatically

This method acquires an authentication token automatically that provides internal system access to Qorus APIs and data if no other explicit authentication information is available

constructor() [1/3]

OMQ::Client::QorusSystemRestHelper::constructor	(	*hash< auto >	opts,
		*softbool	do_not_connect
	)

Creates the object with the given options.

A connection is automatically made unless the do_not_connect argument is False

Parameters

opts	options as follows: api_version: the REST API version (defaults to the latest version) connect_timeout: the connect timeout value in milliseconds timeout: the socket I/O timeout value in milliseconds url: the target URL
do_not_connect	if True, then the object will be created in an unconnected state

Since

Qorus 3.1.1 added the api_version option

constructor() [2/3]

OMQ::Client::QorusSystemRestHelper::constructor	(	string	name,
		*softbool	do_not_connect
	)

creates the object from the given remote connection name

A connection is automatically made unless the do_not_connect argument is False

Parameters

name	the remote connection name to use for the connection
do_not_connect	if True, then the object will be created in an unconnected state

constructor() [3/3]

OMQ::Client::QorusSystemRestHelper::constructor	(	string	user,
		string	pwd
	)

creates the object pointing to the first local listener for the current instance using the given user and password for connecting

Parameters

user	the username for the connection
pwd	the password for the connection

Since

Qorus 5.0 added this to the client version of this class

del()

auto OMQ::Client::QorusSystemRestHelper::del	(	*hash< auto >	opt,
		string	path,
		auto	args,
		*hash< auto >	hdr,
		*reference< hash< auto > >	info
	)

issues an HTTP DELETE REST request against the server and returns the deserialized response

Parameters

opt	output options: lit: if True, outputs the literal response reformat: if True, outputs a reformatted response with verbose formatting (easier to read complex data structures)
path	the URI path for the request
args	any arguments to the REST request
hdr	a hash of optional HTTP header info to add to the request
info	an optional reference to a hash that will be used as an output variable giving a hash of request headers and other information about the HTTP request; if present the hash will contain the following keys: headers: a hash of outgoing HTTP request headers request-uri: the request URI string sent (ex: "GET /services/async/38.0/job HTTP/1.1") body-content-type: the outgoing message body Mime Content-Type value response-headers: a hash of incoming HTTP headers in the response chunked: set to True if the response was received with chunked transfer encoding response-code: the HTTP response code response-body: the raw message body in the response (after any content decoding) response-serialization: the type of message serialization in the response; see RestClient::RestClient::DataSerializationOptions for possible values request-body: the raw message body in the request (before any content encoding) request-serialization: the type of message serialization in the request; see RestClient::RestClient::DataSerializationOptions for possible values

Returns

the deserialized response body
