I am creating an (iphone/android) mobile app using appcelerator titanium. I have a problem using Ti.App.Properties,
I want to save the user's login data (username and password), I used Ti.App.Properties's getList and setList methods to get and set username and password at app startup. It is working fine on iPhone, but on android the data (username and password) are not retrieved at app startup.
here is the code that is executed at app startup :
var userDataArray=[{title:'name',value:''},
{title:'password',value:''}];
if(Ti.App.Properties.hasProperty("userDataArray"))
{
userDataArray = Ti.App.Properties.getList("userDataArray");
}
else
{
Ti.App.Properties.setList("userDataArray",userDataArray);
}
if((Ti.App.Properties.getList("userDataArray")[0].value.length==0)||(Ti.App.Properties.getList("userDataArray")[1].value.length==0))//check if name, password have no values.. on android, this is always the case, which is not correct
{
//go to login page
}
else if((Ti.App.Properties.getList("userDataArray")[0].value.length>0)&&(Ti.App.Properties.getList("userDataArray")[1].value.length>0))//if both username and password exist
{
//start
}
Thank you
i think your overall approach is flawed, you dont need an array just an map
// save the values as a string..
Ti.App.Properties.setString({"username":"myname", "password":"mypassword"}, "CREDENTIALS");
// retrieve the values as a string, but parse it back into an object
var credObject = JSON.parse(Ti.App.Properties.getString("CREDENTIALS"));
// dump the output
Ti.API.debug("Username "+ credObject.username);
Ti.API.debug("Password "+ credObject.password);
two remarks :
arguments for .setString() is opposite, ie Name then Value
Value must be a string, so you have to stringify() it or enter it as a string
I know this is old, but it's still relevant today as there's not a huge amount of help with Titanium. I handle this in two parts.
Part 1) After the user's credentials have been authenticated...
var username = "some username";
var password = "some password";
// Build the object and then convert it to a json string.
oCredentials = new Object();
oCredentials.username = username;
oCredentials.password = password;
var stringCredentials = JSON.stringify(oCredentials);
// Save the credentials
Ti.App.Properties.setString("Credentials", stringCredentials);
Part 2) Before you prompt the user with the login window/popup/whatever...
// Look for credentials
(function() {
var storedCredentials = Ti.App.Properties.getString("Credentials");
if (storedCredentials){
var oJson = JSON.parse(storedCredentials);
// Call your authentication function
// For example, autoAuthenticate(oJson.username, oJson.password);
} else {
// kick the user out to your login window
// For example, $.loginWindow.open();
}
})();

I am using Realm MongoDB for my android app, and I have a problem:
I have different users in my app, and each user has his "cards". The partition of each user's cards is:
"Card=userID".
So, I want to be able to send a card from one user to the other. I do it via a link that includes userID and specific cardID.
So my code looks something like:
Realm.init(this);
mainApp = new App(new AppConfiguration.Builder(APP_ID).defaultSyncErrorHandler((session, error) ->
Log.e("TAG()", "Sync error: ${error.errorMessage}")
).build());
//TEMP CODE
String partition = "Card=611d7n582w36796ce34af106"; //test partition of another user
if(mainApp.currentUser() != null) {
SyncConfiguration config = new SyncConfiguration.Builder(
mainApp.currentUser(),
partition)
.build();
Realm realmLinkCard = Realm.getInstance(config);
Log.d(TAG, "onCreate: cards found- " + realmLinkCard.where(Card.class).findAll().size());
}
The last log always shows 0. I know there are cards for sure because if the user that created the corresponding partition is signed in then it does find the cards.
permissions are set to true for both read and write for the whole sync.
What can the problem be?
You cannot access a Realm by a user who has a different partition.
Instead you can create a mongodb function and call it from your user.
Make your function here:
Check here on How to create a function
And call it by checking here on How to call a function from client
Quick example of a realm function:
exports = async function funcName(partition) {
const cluster = context.services.get('myclustername');
const mycollection = cluster.db('mydbname').collection('mycollectionname');
let result = [];
try {
result = mycollection.findOne({
_partition: partition,
});
} catch (e) {
result.push(e);
return result;
}
return result;
};
To call it, please see above for the documentation as I'm not an Android developper.
I'm a beginner of android programming. I had started a test project which is about using an android app to access web service and run function there. I am using ksoap2 to call the web services.
When I want to login to a database through phone and the web service return a session ID to me. But after that, When I want to run other function in service, and I pass it in session ID, it tell me that there is a null object reference. I tried use the session ID again to get back the login details but it shows that the session doesn't point to any session. This is the method which allow me to connect with web services. While for android, I just simply call using ksoap2.
<WebMethod(True)> _
Public Function CompanyConnectionString() As String
Dim lErrCode, lRetCode As Long
Dim sErrMsg As String = ""
Dim sSessionID As String = ""
Dim oCompany As SAPbobsCOM.Company
oCompany = New SAPbobsCOM.Company
// User and other details to connect
oCompany.Server = "xx.x.x.xx" //ip address
oCompany.DbServerType = SAPbobsCOM.BoDataServerTypes.dst_MSSQL2012
oCompany.DbUserName = "dbUser"
oCompany.DbPassword = "dbPassword"
oCompany.CompanyDB = "CompanyDB"
oCompany.UserName = "User"
oCompany.Password = "Password"
oCompany.LicenseServer = "xx.x.x.xx:xxxxx" // ip
lRetCode = oCompany.Connect
If lRetCode <> 0 Then
oCompany.GetLastError(lErrCode, sErrMsg)
sSessionID = lErrCode & "-" & sErrMsg
Else
sSessionID = Session.SessionID.ToString
Session.Add(sSessionID, oCompany)
''
Cookies.SetCookies(oCompany, "SID")
End If
Return sSessionID
End Function
I found that it might lose the session ID and I can't get back the login details for other functions later. So is that any idea for that? How I gonna do? without this I can't proceed further in my program.
Thank in advance..
Well, the problem had just solved. Me and my friend found out that that is because the sessionID is forgotten due to the max-age=0;. So we add that to our sessionID and it ran.
if (headerKey != null) {
if (headerKey.equals("Set-Cookie")) {
cookieBuilder.append(headerValue + "max-age=86400;");
}
} //headervalue is the sessionID
This will allow the session to stay active for 86400 seconds = 1 day.
So the sessionID can be use for running other function on web service
I need to authenticate via Android on my website (Zend Framework2+ZfcUser+ZfcUserDoctrineORM).
I want to call an url that authenticate me and return a json object that contains my session_id.
I don't know if it is the correct way but whatever i don't know how to do that with zfcUser.
David
Next, i will be able to store this session_id into Shared Preferences storage.
First of all sorry for my English.
In my application i need almost the same.
Ok. So in yoursite.com/module/YourModuleName/Module.php do:
use YourModuleName\Model\YourModuleName;
use YourModuleName\Model\YourModuleName;
class Module {
public function onBootstrap(MvcEvent $e) {
$app = $e->getApplication();
$em = $app->getEventManager();
$sm = $app->getServiceManager();
$auth = $sm->get('zfcuser_auth_service');
$model = new OrdersManager();
if (!$auth->hasIdentity()) {
$em->attach(MvcEvent::EVENT_ROUTE, function($e) use ($app, $sm, $auth, $model) {
$match = $e->getRouteMatch();
// No route, this is a 404
if (!$match instanceof RouteMatch) {
return;
}
$match = $e->getRouteMatch();
$matchParams = $match->getParams();
// $matchParams['hash'] == some url param
if (isset($matchParams['hash'])) {
$model->setDbAdapterColibo($sm->get('dbAdapter'));
$usersSqlObject = $model->getUsers();
$salt = md5('caw');
foreach ($usersSqlObject as $key => $user) {
$hash = hash('sha256', $salt.$param1.$user['user_id']);
if ($hash == $matchParams['hash']) {
$authAdapter = $sm->get('ZfcUser\Authentication\Adapter\AdapterChain');
$request = $app->getRequest();
$request->getPost()->set('identity', $user['email']);
// You may use user password to auth user
$request->getPost()->set('credential', $user['user_id']);
$result = $authAdapter->prepareForAuthentication($request);
$auth->authenticate($authAdapter);
// do your staff with session or other.
// after this you will be redirect to page from where query was
break;
}
}
}
});
}
}
}
Don`t forget about yoursite.com/module/YourModuleName/config/module.config.php
You need to add route with your URL param, to receive it in $matchParams = $match->getParams();
In case I have describe you will be auth and immediately redirect to the site.
Example:
http://example.com/someController/someAction/param1/param2/hash...
the result will be auth and open page http://example.com/someController/someAction/param1/param2/hash...
Ok. This is what i need for my app. Hope this help.
P.S. Some ideas get from Zend Framework 2 - Global check for authentication with ZFCUser
I have a really weird scenario that I'm stuck on. I have a ASP.Net MVC 4 app where I'm authenticating a user and creating an authCookie and adding it to the response's cookies then redirecting them to the target page:
if (ModelState.IsValid)
{
var userAuthenticated = UserInfo.AuthenticateUser(model.UserName, model.Password);
if (userAuthenticated)
{
var userInfo = UserInfo.FindByUserName(model.UserName);
//SERIALIZE AUTHENTICATED USER
var serializer = new JavaScriptSerializer();
var serializedUser = serializer.Serialize(userInfo);
var ticket = new FormsAuthenticationTicket(1, model.UserName, DateTime.Now, DateTime.Now.AddMinutes(30), false, serializedUser);
var hash = FormsAuthentication.Encrypt(ticket);
var authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash) {Expires = ticket.Expiration};
Response.Cookies.Add(authCookie);
if (Url.IsLocalUrl(model.ReturnUrl) && model.ReturnUrl.Length > 1 && model.ReturnUrl.StartsWith("/") && !model.ReturnUrl.StartsWith("//") && !model.ReturnUrl.StartsWith("/\\"))
{
return Redirect(model.ReturnUrl);
}
var url = Url.Action("Index", "Course");
return Redirect(url);
}
ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
This is working just fine in all browsers. I can login and access the secure pages in my app.
My client is requesting an android version of this app. So, I'm trying to figure out how to convert this app into an APK file. My first attempt is to create a simple index.html page with an iframe that targets the application. This works just fine in Firefox and IE 9. However, when accessing the index.html page that contains the iframe that points to the app via Chrome, I get past the login code above and the user gets redirected to the secure controller, but the secure controller has a custom attribute to make sure the user is authenticated:
public class RequiresAuthenticationAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (filterContext.HttpContext.User.Identity.IsAuthenticated) return;
if (filterContext.HttpContext.Request.Url == null) return;
var returnUrl = filterContext.HttpContext.Request.Url.AbsolutePath;
if (!filterContext.HttpContext.Request.Browser.IsMobileDevice)
{
filterContext.HttpContext.Response.Redirect(FormsAuthentication.LoginUrl + string.Format("?ReturnUrl={0}", returnUrl), true);
}
else
{
filterContext.HttpContext.Response.Redirect("/Home/Home", true);
}
}
}
My app is failing on: filterContext.HttpContext.User.Identity.IsAuthenticated. IsAuthenticated is always false, even though the user was authenticated in the code above.
Keep in mind this only happens when accessing the app via iframe in Chrome. If I access the app directly instead of via iframe, then everything works just fine.
Any ideas?
UPDATE:
My controller extends SecureController. In the constructor of SecureController I have the code that deserializes the user:
public SecureController()
{
var context = new HttpContextWrapper(System.Web.HttpContext.Current);
if (context.Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{
var serializer = new JavaScriptSerializer();
var cookie = context.Request.Cookies[FormsAuthentication.FormsCookieName].Value;
var ticket = FormsAuthentication.Decrypt(cookie);
CurrentUser = serializer.Deserialize<UserInfo>(ticket.UserData);
}
else
{
CurrentUser = new UserInfo();
}
//if ajax request and session has expired, then force re-login
if (context.Request.IsAjaxRequest() && context.Request.IsAuthenticated == false)
{
context.Response.Clear();
context.Response.StatusCode = 401;
context.Response.Flush();
}
}
First, you should be deriving from AuthorizeAttribute, not an ActionFilterAttribute. Authorization attributes execute before the method is even called at a higher level of the pipeline, while ActionFilters execute much further down, and other attributes can execute before yours.
Secondly, you aren't showing the code you use to decrypt the ticket and set the IPrincipal and IIdentity. Since that's where the problem is, it's odd that you didn't include it.
I am currently developing an Android application using Flex 4.5.1 and I am having an issue when trying to pass data that I have stored in a SharedObject array to my Web Service for a Database query. the code below shows how I am storing the data in the SharedObject:
var so:SharedObject = SharedObject.getLocal("app");
public var prefsArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefsArray.source.push(getFrsByIDResult.lastResult.id);
so.data.prefs = [prefsArray];
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
I have tested the SharedObject to see if the information is being entered into it correctly and all seems fine. Now I have used the code below in order to retrieve the data from the SharedObject and try and send it to the PHP web Service to run the DB query.
var so:SharedObject = SharedObject.getLocal("app");
var arrCol:ArrayCollection = new ArrayCollection(so.data.prefs);
var str:String = new String(arrCol.toString());
protected function list_creationCompleteHandler(event:FlexEvent):void
{
getPrefsByprefIdsResult.token = prefsService.getPrefsByPrefIds(so.data.prefs);
}
I have tested the Webservice in Flex and have it configured to recieve an Array of Ints (int[]) and it works when i run a test operation on it with two dummy values. However when I try to use the code above to pass the Web Service the Shared Object data I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert []#97e97e1 to mx.collections.ArrayCollection.

I have replaced certain filenames and locations with *'s to protect the work i am doing, but can someone please help me with this issues as I believe it has to be something simple???
Thanks
ok so let me explain in more detail. This is being designed for an Android app like I said, but image what I am trying to do is to store Bookmarks persistently using the Local Shared Object.
The first chunck of code you see above is designed to create the LSO attribute for the bookmark i want to create and imagine that there can be more than one bookmark set at different times like in a web browser. The only way i could find to do this was to store these items/details in an array which I retrieve and then update before saving back to the LSO and saving.
The second piece of code related to imagine a "Bookmarks Page" with a list of all the content that I have bookmarked. Now what I wanted to happen was thta I would be able to call up the LSO attribute which held the id's of the bookmarks and then load up thier details in a list format.
I have managed to create the LSO and store the bookmark deatils in and allow them to be updated and entries added. Also I have made sure that the PHP code that I have pulls back all the database objects relating to the array of id's and this has been tested using flex. The only thing that I cant seem to do is to pass the id's to the PHP web service file. The code in the Web Service file is below if that helps:
public function getPrefsByPrefIds($PrefIds) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE $this->tablename.id IN(" .implode(",", $PrefIds). ")");
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
$rows = array();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
while (mysqli_stmt_fetch($stmt)) {
$rows[] = $row;
$row = new stdClass();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
}
mysqli_stmt_free_result($stmt);
mysqli_close($this->connection);
return $rows;
}
Yes I had already tried that but thanks. I have made some more progress on my own as I have been experimenting with the different types of objects that can be stored in SharedObjects. I have managed to get the solution part working with this code:
This code is designed to capture the boomark info and store it in an arrayCollection before transferring it to a bytesArray and saving
var so:SharedObject = SharedObject.getLocal("app");
public var prefArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefArray.source.push(getCompaniesByIDResult.lastResult.id);
so.data.prefs = [prefArray];
var bytes:ByteArray = new ByteArray();
bytes.writeObject(prefArray);
so.data.ac = bytes;
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
This next code is the designed to retrieve that information from the SahredObjects bytesArray and put it back into an Array Collection
var so:SharedObject = SharedObject.getLocal("app");
var ba:ByteArray = so.data.ac as ByteArray;
var ac:ArrayCollection;
protected function list_creationCompleteHandler(event:FlexEvent):void
{
ba.position = 0;
ac = ba.readObject() as ArrayCollection;
getPrefsByPrefIdsResult.token = prefsService.getPrefsByPrefIds(ac);
}
however as I have said this works in a small way only as if I store only one Bookmark (id) for an item and then go to the bookmarks list the details for that bookark are successfully retrieved, however if I save more than one Bookmark(2 or more id's) the page will not load the details, i do not get an error but I believe it is hanging because it is looking for say id's "1,2" instead of "1" and "2" but i dont know why this is or how to resolve this. I appreciate the advice I have been given but am finding it hard there is no one who can help me with this issue and I am having to do various experiemnts with the code. Can someone please help me with this I would really appreciate it :-) Thanks
