如何在php app和Java EE app之间共享会话? [英] How to share session between php app and Java EE app?
问题描述
我们可能会用Java EE应用程序替换PHP应用程序,但问题是我们要逐个替换模块,这意味着两个应用程序将共存并相互通信。
We may replace a PHP app with a Java EE app, but the problem is we wanna replace the modules one by one, which means two apps would co-exist and communicate with each other.
那么可以在两个应用之间共享用户会话吗?或使用cookie来解决问题?
So is it possible to share the user session between the 2 apps? Or use a cookie to solve the problem?
推荐答案
使用 session_set_save_handler()。
更新
效率明智的,它将是非常小的,与读取文本文件到查询数据库(可能使用现有连接)的区别。
UPDATE Efficiency wise it would be very mininal, the difference from reading a text file to querying a database (presumably using an existing connection).
一些示例代码(简化了我使用的内容) )
Some example code (simplified from what I use)
class Session {
public function __construct() {
session_start();
$this->clean();
}
public function __destruct() {
session_write_close();
}
public function open() {
return TRUE;
}
public function close() {
return TRUE;
}
public function read($id) {
global $Database;
if ($Database->select('session_data FROM sessions WHERE session_id="%s"', $id)) {
list($data) = $Database->fetch(MYSQL_NUM);
return $data;
} else {
return '';
}
}
public function write($id, $data) {
global $Database;
return $Database->replace('sessions SET session_id="%s", session_data="%s", session_updated=%d', array($id, $data, time()));
}
public function destroy($id) {
global $Database;
$_SESSION = array();
return $db->delete('sessions WHERE session_id="%s"', $id);
}
public function clean($expire = 600) {
global $Database;
$Database->delete('FROM sessions WHERE session_updated<%d', $time - $expire);
return TRUE;
}
}
// Declare the functions to use:
session_set_save_handler(array('Session', 'open'), array('Session', 'close'), array('Session', 'read'), array('Session', 'write'), array('Session', 'destroy'), array('Session', 'clean'));
$Session = new Session;
您可以使用 $ _ SESSION ['读取/写入会话数据名称'] =数据;
采用通常的技术。
The you can read/write to the session data using $_SESSION['name'] = data;
in the usual technique.
