6. Auth Plug-in Sample Code
Here is a sample code that explains how to implement init and lookup method.
package com.domain.proxy.plugins ;
import com.brekeke.common.* ;
import com.brekeke.net.usrdir.* ;
public class SampleUserDir implements UserDir
{
Envrnmt env = null ;
Logging log = null ;
LogLevel loglevel = null ;
// init
public void init( Envrnmt env, Logging log ) throws Exception
{
this.env = env ;
this.log = log ;
// Log level setting
// It is obtained from the variable “net.userdir.loglevel.console”
loglevel = new LogLevel( 0,
env.getInt( "net.userdir.loglevel.file", LogLevel.LOG_LEVEL_EXCEPTION ) ) ;
log.println( "SampleUserDir: start", loglevel, LogLevel.LOG_LEVEL_SYSTEM ) ;
//
// Initialization of database connection, etc.
//
}
// lookup
public UserRecord lookup( String username, String method, String destination,
String authinfo ) throws Exception
{
//
// database inquiry for a user information by username key.
//
if ( the user info not found ) {
return ( null ) ;
}
if ( the user doesn’t have the authority to execute the method ) {
return ( null ) ;
}
if ( the user doesn’t have the authority to access the destination SIP-URI ) {
return ( null ) ;
}
UserRecord record = new UserRecord() ;
record.username = username ;
record.password = the plain password obtained from the database
return ( record ) ;
}
}
