Samples

This manual consist info about Flashphoner Samples.
Samples is the examples of applications and functions that can be implemented in Flashphoner.
These examples are opensource and free. You can use them as you wish.

Samples has no official supports from Flashphoner team. This is just examples.

Auto login

Working scheme

Auto login may be used in personal pages.
This way uses token, which used for retrieving SIP login and SIP password at the server-side by this token.
So, SIP password can not be sniffed or intercepted in client-side.

Scheme:

Web page uses flashvars to set token value for swf application.
Flash application sends token value to Flashphoner-server
Flashphoner-server sends a HTTP request to the authentication server, for example: http://authserver.mydomain.com?token=12345abcdef
Authentication server returns an XML:

<sip_user sip_login="vasya" sip_password="123" sip_server="sipnet.ru" auth="true"/>

Flashphoner-server uses the sip_user and sip_password to connect with a voip server.
If auth = "false", Flash-server rejects the connection.

Client implementation

We have changed 4 client files related standard Flashphoner-1.0.3.512 sources, you can find complete sources here: svn://flashphoner.com/branches/auto_login

flashphoner_api FlashAPI.as
flashphoner_api PhoneServerProxy.as
flashphoner_client Phone.html
flashphoner_client phone.mxml

You need to add the token value in html page.
You may use any server-side technology as php, jsp, asp, cgi, e.t.c or plain HTML to do this.
Phone.html
```
flashvars.token="q1zaw2xse3cd";
```

Use accepted token in phone.mxml

phone.mxml

var token:String;
try{
	if (Application.application.parameters != null && Application.application.parameters.token!=null){
		token = Application.application.parameters.token;
	}
} catch (e:Error){
	token = "";
}
DataPhone.getInstance().viewController.showConnectingView();
DataPhone.getInstance().flash_API.loginWithToken(token);

Introduce Flash_API.loginWithToken() function.

Flash_API.as

public function loginWithToken(token:String):int{
	ExternalInterface.call("notifyRegisterRequired",PhoneConfig.REGISTER_REQUIRED);
	if (PhoneConfig.REGISTER_REQUIRED){
	upRegisteredTimer();
	startRegisterTimer();
	}
return phoneServerProxy.loginWithToken(token);
}

Introduce PhoneServerProxy.loginWithToken() function.

PhoneServerProxy.as

public function loginWithToken(token:String):int{
	var modelLocator:ModelLocator = flash_API.modelLocator;
	var obj:Object = new Object();
	obj.registerRequired = PhoneConfig.REGISTER_REQUIRED;
	obj.token = token;
	obj.mode = "flashphoner";
	modelLocator.mode="flashphoner";
	nc.addEventListener(NetStatusEvent.NET_STATUS,netStatusHandler);
	nc.connect(PhoneConfig.SERVER_URL+"/"+PhoneConfig.APP_NAME,obj);
	return 0;
}

Server implementation

Change method onConnect(IClient client, RequestFunction requestFunction, AMFDataList params) of FlashphonerApp.java.
Algorithm is quite simple: if we have no token, then the authorization goes through the usual algorithm, otherwise we will send a request to the auth-server.
Then we parse the xml answer, to get necessary data:sip_login, sip_password, e.t.c.

           if (token == null) {
                //usual algorithm of the authorization
           } else {
                URL url;
                StringBuilder response = new StringBuilder();
                try {
                    url = new URL(AUTH_URL + token);
                    URLConnection conn = url.openConnection();
                    BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));

                    String line;
                    while ((line = rd.readLine()) != null) {
                        response.append(line);
                    }
                    rd.close();
                    Logger.logger.info("response from auth server - " + response.toString());
                } catch (MalformedURLException e) {
                    Logger.logger.error("ERROR - " + AUTH_URL + " is wrong;\n" + e);
                    client.rejectConnection();
                    return;
                } catch (IOException e) {
                    Logger.logger.error("ERROR - " + AUTH_URL + " is wrong;\n" + e);
                    client.rejectConnection();
                    return;
                }
                Document dom;
                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                try {
                    DocumentBuilder db = dbf.newDocumentBuilder();
                    InputStream in = new ByteArrayInputStream(response.toString().getBytes("UTF-8"));
                    dom = db.parse(in);
                } catch (Exception e) {
                    Logger.logger.error("ERROR - '" + response.toString() + "' has wrong format;\n" + e);
                    client.rejectConnection();
                    return;
                }

                Element el = dom.getDocumentElement();

                String temp = el.getAttribute("auth");
