becomeInBackground

[ghost]

Hi,

Is it possible to use becomeInBackground (like in the Android guide from Parse : https://docs.parseplatform.org/android/guide/#setting-the-current-user)

ParseUser.becomeInBackground("session-token-here", new LogInCallback() {
  public void done(ParseUser user, ParseException e) {
    if (user != null) {
      // The current user is now set to user.
    } else {
      // The token could not be validated.
    }
  }
});

Yes, you need to send the token from a cloud function, and then you can do this:

initUserFromToken () async{
    ParseUser user = new ParseUser(null,null,null);
    var response = await user.getCurrentUserFromServer(token:"r:78095e44937ff1732f18ea04d04ad67e");
    if (response.success){
      user = await ParseUser.currentUser();
      print("user"+user.get(ParseUser.keyUsername));
    }
  }

But this is not in release, so we need to wait to the new release, see #58

Oh ok and could you show me an exemple of how you retrieve the token from your cloud function response please ?

[pcg92]

Yes, this is not a cloud function, but you can do something like this, and return the token in the cloud function.

async function getTokenFromUser(user: Parse.User): Promise<string> {
    var randomPassword = generateRandomPw();
    user.setPassword(randomPassword);
    await user.save(null, {useMasterKey: true});
    user = await Parse.User.logIn(user.get("username"), randomPassword);
    return user.getSessionToken();
}

I dont know if this code will work for you, Im doing a login without password, its by email link/code.

The method 'getSessionToken' isn't defined for the classe 'ParseUser'.

Oh, I can't call .getSessionToken() on my user, where this method comes from ?

[pcg92]

Is a js method, in your cloud code you can call it:
https://parseplatform.org/Parse-SDK-JS/api/2.1.0/Parse.User.html#getSessionToken

[ghost]

Oh ok and is it possible to retrieve this token in app with Dart code ?

[pcg92]

Why do you need login with token?, I think that no, this a server thing, and must be done with the masterkey

[ghost]

Because it's the way that I have to login on my server like this : https://docs.parseplatform.org/android/guide/#setting-the-current-user

[pcg92]

You can do the normal way:
https://docs.parseplatform.org/android/guide/#logging-in

This is implemented in this sdk, with username and password
