How to prevent loggedIn users in creating Account in meteor such as calling Accounts.createUser when they are logged in? Can I pass Meteor.userId() when Accounts.createUser is called to detect?

推荐答案

您可以使用 Accounts.onCreateUser 中止帐户创建、添加字段等

You can use Accounts.onCreateUser to abort account creation, add fields, etc.

if (Meteor.isServer) {
  Accounts.onCreateUser(function (options, user) {
    if (Meteor.userId())
      throw new Meteor.Error(400, 'Already logged in!');

    return user;
  });
}
