meteor :onUserCreation

Question

我对 Meteor 很陌生并且已经有很多头疼的问题..也许任何人都可以解释以下内容:

我正在使用 Josh Owen entry package用于 FB、G+ 等登录。最终我想向用户集合添加更多字段。但现在我只是在测试并登录到控制台:

Accounts.onCreateUser(function(options, user) {
    console.log(user);
});

在控制台中，我收到以下错误:

Answer 1

您必须返回用户。来自 Meteor 文档的示例:

// Support for playing D&D: Roll 3d6 for dexterity
Accounts.onCreateUser(function(options, user) {
  var d6 = function () { return Math.floor(Random.fraction() * 6) + 1; };
  user.dexterity = d6() + d6() + d6();
  // We still want the default hook's 'profile' behavior.
  if (options.profile)
    user.profile = options.profile;
  return user;
});

您可以使用 console.log(user);在返回语句之前。
