	this method ensures that thread-local data is set properly
hash< auto >	handleRequest (hash< auto > cx, hash< auto > hdr, *data body)
	this method calls handleRequestImpl() to service the request, if handleRequestImpl() returns NOTHING, then it tries to automatically serve service file resources or serve the default resource if no resource can be matched More...

Detailed Description

this class is used to customize and control the behavior of the Qorus HTTP server as it redirects URLs to Qorus services providing HTTP-based REST services

If any listeners are added to the AbstractServiceRestHandler object, then the URL set in the object is only bound to the new listeners specified in this object. Otherwise, the URL is bound to all listeners in the system HTTP server.

Member Function Documentation

constructor() [1/2]

OMQ::AbstractServiceRestHandler::constructor	(	string	path,
		bool	isregex = False,
		HttpServer::AbstractAuthenticator	auth = new DefaultQorusRBACAuthenticator(),
		*RestSchemaValidator::AbstractRestSchemaValidator	validator
	)

creates the object with the given arguments

Parameters

path	the string or regular expression for the path to match on incoming requests (ex "my-service")
isregex	determines if path is a regular expression or simply the leading path component
auth	the AbstractAuthenticator for the object; if no argument is passed, then the system RBAC authenticator is used; meaning that Qorus application users are required to connect, and the users must have the OMQ::QR_LOGIN role to connect as well
validator	an option REST schema validator object to validate and process incoming and outgoing requests

Example:

class MyRestHandler inherits AbstractServiceRestHandler {
    constructor() : AbstractServiceRestHandler("my-service", svc_get_resource_data("my-swagger-schema-v1.0.yaml")) {
    }
}

Note

that the path argument defaults to a string instead of a regular expression in this constructor

constructor() [2/2]

OMQ::AbstractServiceRestHandler::constructor	(	string	path,
		HttpServer::AbstractAuthenticator	auth = new DefaultQorusRBACAuthenticator(),
		*RestSchemaValidator::AbstractRestSchemaValidator	validator
	)

creates the object with the given arguments

Parameters

path	the string or regular expression for the path to match on incoming requests (ex "my-service")
auth	the AbstractAuthenticator for the object; if no argument is passed, then the system RBAC authenticator is used; meaning that Qorus application users are required to connect, and the users must have the OMQ::QR_LOGIN role to connect as well
validator	an option REST schema validator object to validate and process incoming and outgoing requests

Example:

class MyRestHandler inherits AbstractServiceRestHandler {
    constructor() : AbstractServiceRestHandler("my-service", svc_get_resource_data("my-swagger-schema-v1.0.yaml")) {
    }
}

Note

that the path argument defaults to a string instead of a regular expression in this constructor
