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
• "swagger_base_path": in case a REST validator is used, the base path in the schema can be overridden with this option (applies to any REST validator; not just Swagger validators)
• "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

constructor()

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
options	connection options

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

Additional Attributes

• error a custom error string

Exceptions

CONNECTION-OPTION-ERROR

missing or invalid connection option

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
