Detailed Description

class to call the system REST API from the client library

Member Function Documentation

◆ 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,

		*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
