找到this question后,我的Silex会话至少得到了一个ID,但我没有看到会话数据在不同的页面浏览量中保存:
require(__DIR__.'/vendor/autoload.php'); // Composer autoload
$app = new Silex\Application();
$app['debug'] = true;
$app['db'] = $app->share(function() { // Database connector as a service
return new PDO('mysql:host=localhost;dbname=myawesome_db', 'user', 'paswd');
});
$app['session.db_options'] = array(
'db_table' => 'php_sessions',
'db_id_col' => 'session_id',
'db_data_col' => 'session_value',
'db_time_col' => 'session_time',
);
$app['session.storage.pdohandler'] = $app->share(function () use ($app) {
return new Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler(
$app['db'],
$app['session.db_options'],
$app['session.storage.options']
);
});
$app['session.storage'] = $app->share(function() use ($app) {
return new Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage(
$app['session.storage.options'],
$app['session.storage.pdohandler']
);
});
$app->register(new Silex\Provider\SessionServiceProvider()); // Start session management
$app['session']->start();
$app->get('/session-set', function() use ($app) {
$app['session']->set('foobar', 'test');
$app['session']->save();
$out = "User session is: ".$app['session']->getId()."<br />\n";
$out .= "Session variable is: ".var_export($app['session']->get('foobar'), true)."<br />\n";
return $out;
});
$app->get('/session-get', function() use ($app) {
$out = "User session is: ".$app['session']->getId()."<br />\n";
$out .= "Session variable is: ".var_export($app['session']->get('foobar'), true)."<br />\n";
return $out;
});
$app->run(); // Off into the sunset
/session-set
页面显示foobar
会话变量的值,但/session-get
页面没有。有谁能帮我弄明白为什么?
答案 0 :(得分:0)
我的解决方案结果是PDO数据库连接未正确设置(其中一个列名称错误)。但是,默认情况下,PDO MySQL连接在出错时不会抛出异常,只会设置ErrorInfo()
详细信息。一旦我打开异常抛出我的PDO连接,我发现错误并修复它。我还向Symfony提交了一个补丁,以确保会话PDO对象启用了异常抛出,以避免其他人遇到此问题。
