Detailed Description

JsonRpcHandler class definition; to be registered as a handler in the HttpServer class.

Member Function Documentation

JsonRpcHandler::JsonRpcHandler::addMethod	(	string	name,
		code	func,
		string	text,
		string	help,
		auto	logopt,
		auto	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	(	HttpServer::AbstractAuthenticator	n_auth,
		list< auto >	n_methods,
		*code	n_getLogMessage,
		bool	n_dbg = `False`,
		*string	n_get_prefix,
		*code	n_log
	)

creates the handler with the given method list

Parameters

n_auth	an authentication object (use new AbstractAuthenticator() for no authentication)
n_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
n_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 hash), the method definition as passed in the methods argument to this constructor, and a reference to the arguments in this call
n_dbg	this parameter is set to True, then additional information will be logged when errors occur
n_get_prefix	prefix to add to derived methods with GET requests if no "." characters are in the path
n_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
