the base abstract class for REST handler classes

Member Function Documentation

◆ dispatch()

hash<HttpServer::HttpHandlerResponseInfo> RestHandler::AbstractRestClass::dispatch ( RestHandler  rh,
string  mn,
*hash< auto >  ah,
hash< auto >  cx 
)
private

this method is called to dispatch requests on the given object

Parameters
rhthe RestHandler object
mnthe method name
ahthe holds URI and / or message body arguments for the REST call; if a request has both URI query arguments and message body arguments, then this value will be a combination of URI query arguments and deserialized message body arguments with URI query arguments taking precedence over the message body arguments
cxcall context hash; this hash will have the following keys:
  • socket: the bind address used to bind the listener ("socket-info" provides more detailed information)
  • socket-info: a hash of socket information for the listening socket (as returned by Qore::Socket::getSocketInfo())
  • peer-info: a hash of socket information for the remote socket (as returned by Qore::Socket::getPeerInfo())
  • url: a hash of broken-down URL information (as returned from parse_url())
  • id: the unique HTTP connection ID
  • ssl: True if the request was encrypted with HTTPS, False if not
  • listener-id: the HTTP server listener ID (see HttpServer::HttpServer::getListenerInfo())
Returns
the return value is the same as the return value for HttpServer::AbstractHttpRequestHandler::handleRequest()

◆ doGetPossibleSubClasses()

*hash<string, bool> RestHandler::AbstractRestClass::doGetPossibleSubClasses ( hash< auto >  cx)
private

returns a set of possible subclasses for a particular request

Parameters
cxthe HTTP call context hash
Returns
a set of possible subclasses for the request
Since
RestHandler 1.3

◆ unknownSubClassError()

hash<HttpServer::HttpHandlerResponseInfo> RestHandler::AbstractRestClass::unknownSubClassError ( string  cls_name,
hash< auto >  cx 
)
private

returns a 404 Not Found response when a request tries to access an unknown subclass

Parameters
cls_namethe URI path element that could not be matched to a REST subclass
cxthe HTTP call context hash
Returns
REST response information
Since
RestHandler 1.3 added the cx argument
