有什么方法可以在不通过登录/注册调用和localStorage的情况下将当前用户对象缓存在内存中？

Question

In Parse, a user object is created and cached in memory after login or signup successfull calls, and can be retrieved using current.

My need now is to create and cache the user object in memory without going through the login/signup calls and also without having to store the object in the local storage. I mean something like assigning a new user object in memory so that Parse.User.current will return it. Again I shouldn't go through login and signup.

If I go through login call:

Parse.User.logIn(login, password, {
      success: function(user) {
      // At this moment the user object is cached
      },
       error: function(error) {
      }
});

But in my case, I don't go through the login, but instead I have the user id, and with it I can get the user object:

var query = new Parse.Query(Parse.User);
query.equalTo('objectId',result.id);
query.first({

        success: function(user){
                // Now I want to cache the user in memory so that Parse.User.current will return it to me whenever I want
                // I tried to cache this in localStorage but whenever I retrieve it, I get null object
        },  
        error: function(error){
                alert(error);
        }
});

Answer 1

It is not entirely clear what you want, but you could simply call toJSON() on the current user and save that JSON in your cache, either local storage or whatever you are using.

Is there more you want? If so please expand your question.

Answer 2

Parse users are logged in until they log out, parse caches the user for you.

You can access that cached user by doing this in your code:

var query = new Parse.Query(Parse.User.Current());
