Public Member Methods

 constructor (string path, HttpServer::AbstractAuthenticator auth=new DefaultQorusRBACAuthenticator())
 creates the object with the given arguments More...
 
hash< HttpResponseInfo > handleRequest (HttpListenerInterface listener, Socket s, hash< auto > cx, hash< auto > hdr, *data body)
 this method ensures that thread-local data is set properly
 
OMQ::QorusWebSocketConnection getConnectionImpl (hash< auto > cx, hash< auto > hdr, string cid)
 called when a connection is established; the default implementation creates an OMQ::QorusWebSocketConnection object
 
- Public Member Methods inherited from OMQ::AbstractServiceHttpHandler
OMQ::ThreadLocalData otld ()
 thread-local data to add before calling handleRequest()
 
 constructor (string n_path, *softlist< auto > n_content_type, *softlist< auto > n_special_headers, HttpServer::AbstractAuthenticator n_auth=new DefaultQorusRBACAuthenticator(), bool n_isregex=True)
 creates the object with the given arguments More...
 
hash< auto > getServiceInfo ()
 returns a hash with info about the linked service
 
 addListener (hash< HttpServer::HttpListenerOptionInfo > opt)
 adds a listener from a bind string in the format: "address:port" (ex: "192.168.20.1:8011") More...
 
 addListener (softstring bind, hash< HttpServer::HttpListenerOptionInfo > opt)
 adds a listener from a bind string in the format: "address:port" (ex: "192.168.20.1:8011") More...
 
 addListener (softstring bind, *string cert_path, *string key_path, *string key_password, *hash< HttpServer::HttpListenerOptionInfo > opt)
 adds a listener from a bind string in the format: "address:port" (ex: "192.168.20.1:8011") More...
 
 addListener (softstring bind, *Qore::SSLCertificate cert, *Qore::SSLPrivateKey key, *hash< HttpServer::HttpListenerOptionInfo > opt)
 adds a listener from a bind string in the format: "address:port" (ex: "192.168.20.1:8011") More...
 
 addListeners (softlist< auto > l)
 adds a list of listeners; each element should be either a bind string in the format: "address:port" (ex: "192.168.20.1:8011") or an integer port, meaning to bind on all interfaces on that port More...
 
final *hash< auto > saveThreadLocalData ()
 called before handleRequest() any data returned here will be given to restoreThreadLocalData() after the handleRequest() call
 
final restoreThreadLocalData (*hash< auto > data)
 called after handleRequest() with any data returned from saveThreadLocalData()
 
 log (int ll, string fmt)
 logs to the service log file
 
 setUserIndexInfo (string heading, string title, string url)
 sets heading and title for user HTTP services
 
 clearUserIndexInfo ()
 clears heading and title into for user HTTP services More...
 
hash< HttpResponseInfo > handleRequest (HttpListenerInterface listener, Socket s, hash< auto > cx, hash< auto > hdr, *data body)
 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...
 
string getRequestPath (string hpath)
 returns the request path with the common leading part of the URL stripped off and also any URI query argument stripped off
 
*hash< auto > handleRequestImpl (reference< hash< auto >> cx, hash< auto > hdr, *data body)
 this method is called by this class's handleRequest() before trying to service the request automatically based on service file resources More...
 
 setDefaultResource (string name)
 sets the default service file resource to be rendered when the request is not matched to a resource and handleRequestImpl() does not return a response
 
private AbstractStreamRequest getStreamRequestImpl (HttpListenerInterface listener, Socket s, hash< auto > cx, hash< auto > hdr, *data body)
 returns the AbstractStreamRequest object for handling chunked requests
 
private AbstractServiceStream getServiceStreamRequestImpl (Socket s, hash< auto > cx, hash< auto > hdr, *data body)
 returns the AbstractStreamRequest object for handling chunked requests

Detailed Description

this class is used to allow Qorus services to provide dedicated WebSocket server services to external clients

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()

OMQ::AbstractServiceWebSocketHandler::constructor ( string  path,
HttpServer::AbstractAuthenticator  auth = new DefaultQorusRBACAuthenticator() 
)

creates the object with the given arguments

Parameters
paththe regular expression for the path to match on incoming requests (ex "^my-service")
auththe 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
Example:
class MyWebSocketHandler inherits OMQ::AbstractServiceWebSocketHandler {
constructor() : AbstractServiceWebSocketHandler("my-websocket") {
}
WebSocketHandler::WebSocketConnection getConnectionImpl(hash<auto> cx, hash<auto> hdr, string cid) {
return new WebSocketHandler::WebSocketConnection(self);
}
}
