Detailed Description

defines a YAML-RPC client class

The YamlRpcClient class will correctly serialize YAML-RPC messages, send them to the server, deserialize the responses and return a Qore-language data structure for the response.

YAML-RPC is a proprietary HTTP-based RPC protocol; for a description of the YAML-RPC protocol implemented by the YamlRpcClient class, see YAML-RPC Protocol Implementation.

Note

• if no URI path is given in the constructor(), the default path used is "/YAML"
• subclassed from Qore''s HTTPClient class

Member Function Documentation

call()

auto YamlRpcClient::YamlRpcClient::call

(

string

method

)

makes a method call to the YAML-RPC server using the remaining arguments after the method name as the list of arguments to send

Parameters

method

the remote method to call

Returns

the value returned from the server; if no error occurred, then a hash is returned with a result key (see YAML-RPC Non-Error Responses), otherwise a hash is returned with an error key containing the error information (see YAML-RPC Error Responses)

callArgs()

auto YamlRpcClient::YamlRpcClient::callArgs	(	string	method,
		auto	args
	)

makes a call to the YAML-RPC server using the second argument as the list of arguments to send

Parameters

method	the remote method to call
args	the argument(s) to the call

Returns

the value returned from the server; if an error response is returned, an exception is raised

callArgsWithInfo()

auto YamlRpcClient::YamlRpcClient::callArgsWithInfo	(	reference< auto >	info,
		string	method,
		auto	args
	)

makes a call to the YAML-RPC server using the third argument as the list of arguments to send

Parameters

info	a reference to a hash with technical information about the call
method	the remote method to call
args	the argument(s) to the call

Returns

the value returned from the server; if an error response is returned, an exception is raised

constructor() [1/2]

YamlRpcClient::YamlRpcClient::constructor

(

bool

do_not_connect = False

)

simple constructor using default arguments

Parameters

do_not_connect

if False (the default), then a connection will be immediately established to the remote server

constructor() [2/2]

YamlRpcClient::YamlRpcClient::constructor	(	hash	opts = hash(),
		bool	do_not_connect = False
	)

calls the base class HTTPClient constructor, overrides the "protocols" key to "yamlrpc"

Parameters

opts

valid options are: url: A string giving the URL to connect to default_port: The default port number to connect to if none is given in the URL http_version: Either '1.0' or '1.1' for the claimed HTTP protocol version compliancy in outgoing message headers default_path: The default path to use for new connections if a path is not otherwise specified in the connection URL max_redirects: The maximum number of redirects before throwing an exception (the default is 5) proxy: The proxy URL for connecting through a proxy timeout: The timeout value in milliseconds (also can be a relative date-time value for clarity, ex: 5m) connect_timeout: The timeout value in milliseconds for establishing a new socket connection (also can be a relative date-time value for clarity, ex: 30s)

do_not_connect

if False (the default), then a connection will be immediately established to the remote server
