[英]How can I assign a session key with Javascript?
I have a PHP program, called login.我有一个 PHP 程序,称为登录。
When the user passes something, like email and password, login.php
will return a session key to the user, if the login succeeds.当用户传递一些东西,比如 email 和密码,
login.php
将返回一个 session 密钥给用户,如果登录成功。
And I have JavaScript code to call this function to do the login.我有 JavaScript 代码来调用这个 function 进行登录。
How can I store this session key to identify whether the user is logged in?如何存储此 session 密钥以识别用户是否已登录?
The session is stored in a cookie by the server. session 由服务器存储在 cookie 中。
You don't need to do anything on the client.您无需在客户端上执行任何操作。
a session is serverside.. not clientside.. so you cant set it through js一个 session 是服务器端..不是客户端..所以你不能通过 js 设置它
Sessions are declared manually like this:会话是这样手动声明的:
$_SESSION['user'] = $_POST['username']; // or any other variable
You can then check on the other pages with PHP like this:然后,您可以使用 PHP 检查其他页面,如下所示:
if(isset($_SESSION['user'])){
//do this if true
}
