Detailed Description

abstract base class for external authentication

This class should be inherited by a class providing real authentication

Member Function Documentation

authenticate()

HttpServer::AbstractAuthenticator::authenticate	(	string	user,
		string	pass = ''
	)

called to authenticate a user for a connection

This method will only be called if requiresAuthentication() returns True

Parameters

user	the username to authenticate
pass	the password for the user

Exceptions

AUTHENTICATION-ERROR

subclasses should throw this exception if the user cannot be authenticated (must be overridden in child classes; this parent method will never throw any exceptions; all connections are accepted by default)

authenticateByIP()

HttpServer::AbstractAuthenticator::authenticateByIP	(	string	ip,
		reference< string >	user
	)

called when the connection requires authentication, but no authentication credentials were supplied, to try to authenticate the connection based on the source IP address

This method will only be called if requiresAuthentication() returns True and no authentication credentials are supplied with the request

Parameters

ip	the IP address of the source connection
user	a reference to a string that will be populated with the username to use if the request can be authenticated based on the source IP address (this method returns the string "admin")

Exceptions

AUTHENTICATION-ERROR

subclasses should throw this exception if the user cannot be authenticated (however this base class method as implemented here will never throw any exceptions

authenticateRequest()

*hash<HttpResponseInfo> HttpServer::AbstractAuthenticator::authenticateRequest	(	HttpListenerInterface	listener,
		hash< auto >	hdr,
		reference< hash >	cx
	)

primary method called to authenticate each request

Parameters

listener	an HttpListenerInterface object for the listener serving the request for logging purposes
hdr	a hash of request headers
cx	a reference to the call context hash; set the "user" key to the user name if a user was identified and authorized; this hash will have the following keys: header-info: a hash of information about the request header with the following keys: request-uri: gives the request URI in an HTTP request body-content-type: this is the "Content-Type" header without any charset declaration charset: if there is a charset declaration in the "Content-Type" header, the value is returned in this key close: set to True if the connection should be closed after responding, False if not (as derived from the request header) accept-charset: this key will be set to an appropriate value from any "Accept-Charset" header; if any of "*", "utf8", or "utf-8" are present, then this will be set to "utf8", otherwise it will be set to the first requested character encoding in the list accept-encoding: a hash where keys are values from any "Accept-Encoding" header and the values are True 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 Qore::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::getListenerInfo()) user: the current RBAC username (if any) root_path: the root URL path matched if the request was matched by a URL prefix

Returns

returns NOTHING if there were no errors, otherwise returns a hash with the following keys to indicate an authentication or authorization error:

• "code": the HTTP response code
• "body": the error message body
• "hdr": an optional hash of headers for the error response

getRealm()

string HttpServer::AbstractAuthenticator::getRealm

(

)

returns the authentication realm as a string

Returns

the authentication realm as a string (default: "Default Authentication Realm")

requiresAuthentication()

bool HttpServer::AbstractAuthenticator::requiresAuthentication

(

)

called to check if the connection requires authentication

Returns

True if authentication is enabled, False if not (False is the default value returned)
