потеря сессии на php сервере при использовании android-запроса
У меня проблема с использованием метода AndroidQuery ajax …
Вот мой PHP-код на сервере для page1.php:
<?php
session_start();
$_SESSION["valid_user"] = "mysession";
echo '{ "value" : "S_'.$_SESSION["valid_user"].'" }' ;
?>
и ниже php-код на сервере для page2.php:
<?php
session_start();
echo '{ "value" : "S_'.$_SESSION["valid_user"].'" }' ;
?>
Итак, на Android, под изображением экрана моего приложения:
http://i.stack.imgur.com/4esSo.png
Событие для кнопки «Run page 1»:
aQuery.ajax("http://www.example.com/page1.php", JSONObject.class, new AjaxCallback<JSONObject>() {
@Override
public void callback(String url, JSONObject json, AjaxStatus status) {
Toast.makeText(aQuery.getContext(), json.getString("valid_user"), Toast.LENGTH_LONG).show(); // print : S_mysession
}
});
и событие для кнопки «запустить страницу 2»:
aQuery.ajax("http://www.example.com/page2.php", JSONObject.class, new AjaxCallback<JSONObject>() {
@Override
public void callback(String url, JSONObject json, AjaxStatus status) {
Toast.makeText(aQuery.getContext(), json.getString("valid_user"), Toast.LENGTH_LONG).show(); // print : S_
}
});
сначала я нажимаю кнопку «запустить страницу 1», а затем показываю «S_mysession», поэтому затем я нажимаю кнопку «запустить страницу 2» и затем показываю «S_» !!! Зачем терять мой сеанс в другом соединении AQuery.ajax ?!
Помогите мне, пожалуйста …
Решение
Я использую плагин org.apache.httpcomponents, и это работает!
просто добавьте сюда коды в файл build.gradle:
compile 'org.apache.httpcomponents:httpcore:4.4.4'
compile 'org.apache.httpcomponents:httpmime:4.3.5'
так что используйте в классе:
