Server communication

[sofiane-soufi]

Hi again,

I'm having some problems creating a base server to read the login credentials from the client you made. Here's my code:

HaxeExtension.hx

`package;

import java.Lib;
import com.smartfoxserver.v2.extensions.SFSExtension;
import com.smartfoxserver.v2.extensions.ExtensionLogLevel;
import com.smartfoxserver.v2.core.SFSEventType;

@:nativeGen
class HaxeExtension extends SFSExtension
{
@:overload override public function init()
{
this.log("Extension started");

	this.addEventHandler(SFSEventType.USER_LOGIN, cast(UserLogin, java.lang.Class<Dynamic>));
}

public function log(obj:Dynamic):Void
{
	this.trace(ExtensionLogLevel.WARN, java.NativeArray.make(Std.string(obj) ));
}	

}`

UserLogin.hx

`package;

import com.smartfoxserver.v2.entities.User;
import com.smartfoxserver.v2.core.ISFSEvent;
import com.smartfoxserver.v2.core.SFSEventParam;
import com.smartfoxserver.v2.entities.data.ISFSObject;
import com.smartfoxserver.v2.entities.data.SFSObject;
import com.smartfoxserver.v2.extensions.BaseServerEventHandler;
import com.smartfoxserver.v2.extensions.ExtensionLogLevel;

@:nativeGen
class UserLogin extends BaseServerEventHandler
{

@:overload
override public function handleServerEvent(event:ISFSEvent):Void
{
	var credentials:SFSObject = event.getParameter(cast SFSEventParam.LOGIN_IN_DATA);
	var user:User = event.getParameter(cast SFSEventParam.USER);
	this.trace(ExtensionLogLevel.WARN, java.NativeArray.make(user.getName()+" joined the game with the sid: "+credentials.getUtfString("sid")));
}

}`

Here's what I get in the logs:

16 Mar 2017 | 12:06:21,368 | INFO | SocketReader | bitswarm.sessions.DefaultSessionManager | | Session created: { Id: 3, Type: DEFAULT, Logged: No, IP: 0 } on Server port: 9933 <---> 0

Never mind!

Here's what I did to solve my problem:

HaxeExtension.hx

`package;

import java.Lib;
import com.smartfoxserver.v2.extensions.SFSExtension;
import com.smartfoxserver.v2.extensions.ExtensionLogLevel;
import com.smartfoxserver.v2.core.SFSEventType;

@:nativeGen
class HaxeExtension extends SFSExtension
{
@:overload override public function init()
{
this.log("Extension started");

	this.addEventHandler(SFSEventType.USER_LOGIN, cast(UserLogin, java.lang.Class<Dynamic>));
}

public function log(obj:Dynamic):Void
{
	this.trace(ExtensionLogLevel.WARN, java.NativeArray.make(Std.string(obj) ));
}	

}`

UserLogin.hx

`package;

import com.smartfoxserver.v2.entities.User;
import com.smartfoxserver.v2.core.ISFSEvent;
import com.smartfoxserver.v2.core.SFSEventParam;
import com.smartfoxserver.v2.entities.data.ISFSObject;
import com.smartfoxserver.v2.entities.data.SFSObject;
import com.smartfoxserver.v2.extensions.BaseServerEventHandler;
import com.smartfoxserver.v2.extensions.ExtensionLogLevel;

@:nativeGen
class UserLogin extends BaseServerEventHandler
{

@:overload
override public function handleServerEvent(event:ISFSEvent):Void
{
	var user:String = event.getParameter(cast SFSEventParam.LOGIN_NAME);
	var params:SFSObject = event.getParameter(cast SFSEventParam.LOGIN_IN_DATA);
	var sid:String = params.getUtfString("sid");
	
	
	this.trace(ExtensionLogLevel.WARN, java.NativeArray.make(user+" joined the game with the sid : "+sid));
}

}`
