Using Session php android

Question

In my android application i call php web service .at the first service is checking the login page if the user and the password are correct ,i create a new session for this user and i call this variable in another php page to treat some request .. The problem is when i call this variable from my android app it tells me:Undefined index :id_utilisateur in c:/wamp..../ajouteroffre.php

My login page is:

  session_start();
  include("mesfonction.php");
  require "init.php";

   $user_name =@$_POST["login_name"]; 
   $user_pass =@$_POST["login_pass"]; 


  $rows  = checkloginConnexion($user_name, $user_pass);
   $count = count($rows);

    if( $count==1 )
    {
    $_SESSION['id_utilisateur']=$rows[0]['ID_User'];
    $_SESSION['profile']=$rows[0]['Profil'];

    $_SESSION['login']=$user_name;
    $_SESSION['pass']=$user_pass;  

    if ($_SESSION['profile'] =='Employeur') 
       {


       echo "Connecte en tant que Employeur..";

        }       

     if ($_SESSION['profile'] =='Chercheur') 
       {
        echo "Connecte en tant que Candidat..";
        }           


      }
     else 
      {
     echo "Erreur:Connexion...Reesseyez!";
     }

    ?>

My second page is:

<?php  
 session_start();
 require "init.php";  
 include("mesfonction.php");


 $id_user =$_SESSION["id_utilisateur"];
 $ThisUser = getInfopro($id_user);

?>

i think your android application didn't request with cookie like sessionID, so the web server can not find the session.

Differences between cookies and sessions:

Sessions are server-side files that contain user information, while Cookies are client-side files that contain user information. Sessions have a unique identifier that maps them to specific users. This identifier can be passed in the URL or saved into a session cookie.

Most modern sites use the second approach, saving the identifier in a Cookie instead of passing it in a URL (which poses a security risk). You are probably using this approach without knowing it, and by deleting the cookies you effectively erase their matching sessions as you remove the unique session identifier contained in the cookies.

you can use OAuth2.0 to solve the problem http://oauth.net/2/

Process is as follows：

step1:input username and password in android app
step2:android app send the info to web service
step3:after web service authenticating,return a token to app
step4:get other resource with the token

“i tried the web service at localhost it gives me the right response” You are using a browser？

Oumayma Jaziri Over a year ago

yes i test it at the browser it gives me the value 2 which is stored in $_SESSION['id_utilisateur']; ... But when i call it from android it return an empty message without any error

suibber Over a year ago

i think ,the browser will automatically maintain a cookie but not android.so the web server didn't who you are when you call it from android
