Java播放！ 2 - 使用Cookie的用户管理 [英] Java Play! 2 - User management with cookies

问题描述

我想透过Cookie管理我的使用者。这不是那么容易，因为没有关于这个主题的文档。

I am trying to manage my user via cookie. It's not that easy because there is absolutely no documentation about this topic.

在示例zentask的帮助下，我做了：

With the help of the sample "zentask" I made this:

session("username", filledForm.field("username").value());

public class Secured{

    public static Session getSession() {
        return Context.current().session();
    }

    public static String getUsername() {
        return getSession().get("username");
    }

    public static boolean isAuthorized() throws Exception {
        String username = getUsername();
        if (username == null)
            return false;
        long userCount = DatabaseConnect.getInstance().getDatastore()
                .createQuery(User.class).field("username").equal(username)
                .countAll();

        if (userCount == 1)
            return true;

        return false;

    }

我使用它像这样：

public static Result blank() throws Exception {

        if (Secured.isAuthorized())
            return ok(Secured.getUsername());
        else
            return ok(views.html.login.form.render(loginForm));

    }

现在我有几个问题/问题：

Now I have several questions/problems:

• 1。）Cookie不受保护，并且总是看起来相同。例如bdb7f592f9d54837995f816498c0474031d44c1a-username％3Akantaki

• 1.) Cookie is not dectypted and always looks the same. eg bdb7f592f9d54837995f816498c0474031d44c1a-username%3Akantaki

2。）Security.Authenticator类是什么？

2.) What does the class Security.Authenticator do?

3。）我认为通过cookies的用户管理是一个很常见的问题，是打！2.0给我一个完整的解决方案？或者至少有一些文档吗？

3.) I think user management through cookies is a very common problem, does play!2.0 offer me a complete solution? Or is there at least some documentation?
