Member Function Documentation

JsonRpcHandler::JsonRpcHandler::addMethod	(	string	name,
		code	func,
		string	text,
		string	help,
		any	logopt,
		any	cmark
	)

adds a method to the handler dynamically

Parameters

name	a regular expression to use for matching the method name
func	a string (giving a function name to call), a call reference, or a closure to call with the deserialized arguments to the method; the return value will be serialized to XML-RPC and sent back to the caller
text	the human-readable name of the method
help	help text for the method
logopt	log options which can be used by a custom logger (see the getLogMessage parameter)
cmark	any value that will be added in the method hash under the `"cmark"` key

JsonRpcHandler::JsonRpcHandler::constructor	(	AbstractAuthenticator	auth,
		list	methods,
		*code	getLogMessage,
		bool	dbg = `False`,
		*string	get_prefix,
		*code	log
	)

creates the handler with the given method list

Parameters

auth	an authentication object (use new AbstractAuthenticator() for no authentication)
methods	a list of hashes with the following keys: `name:` a regular expression to use for matching the method name `function:` a string (giving a function name to call), a call reference, or a closure to call with the deserialized arguments to the method; the return value will be serialized to JSON-RPC and sent back to the caller `text:` the human-readable name of the method `help:` help text for the method `logopt:` (optional - by convention) log options which can be used by a custom logger (see the getLogMessage parameter) `cmark:` (optional) a data structure to be added to the context argument when the request method is called
getLogMessage	an optional closure or call reference to be called when an incoming request is received; if this is set then it will be called with the following arguments: a context hash (see HttpServer::AbstractHttpRequestHandler::handleRequest() for a description of the context h ash), the method definition as passed in the methods argument to this constructor, and a reference to the arguments in this call
dbg	this parameter is set to True, then additional information will be logged when errors occur
get_prefix	prefix to add to derived methods with GET requests if no "." characters are in the path
log	an optional closure or call reference to be called when logging

Exceptions

JSON-RPC-CONSTRUCTOR-ERROR missing "name", "function", or "text" key in method hash, \c "function" key not assigned to a callable value
