Detailed Description

class for REST HTTP connections; returns RestClient::RestClient objects

supports the following options:

• "connect_timeout": connection timeout to use in milliseconds
• "content_encoding": this sets the send encoding (if the "send_encoding" option is not set) and the requested response encoding; for possible values, see EncodingSupport
• "data": see RestClient::RestClient::DataSerializationOptions for possible values when used with the null REST schema validator; the default is "auto"
• "error_passthru": if True then HTTP status codes indicating errors will not cause a REST-RESPONSE-ERROR exception to be raised, rather such responses will be passed through to the caller like any other response
• "headers": an optional hash of headers to send with every request, these can also be overridden in request method calls; also a string giving headers can be given in the format: header1=value, header2=value; the value will be parsed with parse_to_qore_value()
• "http_version": HTTP version to use ("1.0" or "1.1", defaults to "1.1")
• "max_redirects": maximum redirects to support
• "proxy": proxy URL to use
• "redirect_passthru": if True then redirect responses will be passed to the caller instead of processed
• "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
• "swagger": the path to a Swagger 2.0 REST schema file for runtime API validation (see the Swagger module); conflicts with validator
• "timeout": transfer timeout to use in milliseconds
• "validator": an AbstractRestSchemaValidator object to validate request and response messages; conflicts with swagger

Note

additionally supports the following runtime option in getImpl():

• "validator": an AbstractRestSchemaValidator object for REST message validation (if present, overrides any REST schema validation option provided as a connection option)

See also

RestClient::constructor() for more information on the above options

Since

RestConnection 1.4

Member Function Documentation

constructor() [1/2]

deprecated RestClient::RestConnection::constructor	(	string	name,
		string	desc,

constructor() [2/2]

RestClient::RestConnection::constructor	(	string	name,
		string	description,
		string	url,
		hash< auto >	attributes = {},
		hash< auto >	options = {}
	)

creates the RestConnection connection object

Parameters

name	the name of the connection
description	connection description
url	connection URL (potentially with password info)
attributes	various attributes. See below

See AbstractConnection::constructor() for attributes and options reference.

Additional Attributes

• error a custom error string

getDataProvider()

DataProvider::AbstractDataProvider RestClient::RestConnection::getDataProvider

(

)

returns a data provider object for this connection, if supported by any REST schema validator object

Returns

a data provider object for this connection, if supported by any REST schema validator object

Exceptions

DATA-PROVIDER-ERROR

this object does not support the data provider API

getImpl()

RestClient RestClient::RestConnection::getImpl ( bool  connect = True, *hash< auto >  rtopts  )

privatevirtual

returns a RestClient object

Parameters

connect	if True, then the connection is returned already connected

(

)

gets options

Returns

returns a hash with the following supported options:
