如何在登录尝试中找到当前用户

Question

我正在尝试添加一个简单的处理程序来处理用户登录。我认为这很简单但是......由于某种原因我无法在 Accounts.onLogin 回调中找到用户。

Meteor.startup ->
  if Meteor.isServer

    Accounts.onLogin ->
      console.log("login | onLogin")
      user = Meteor.user()
      console.log("login | onLogin user:", user)

但这永远不会达到第二个 console.log。

如果我注释掉 user = Meteor.user() 则它不会崩溃。

服务端meteor是否可以通过这种方式获取currentUser？

对于客户端，我可以用跟踪器收听，但是我更愿意在回调事件和服务器端使用它。

奇怪的是，错误总是指向 Meteor.userId()，即使我没有调用它。

您在这里遗漏了一些东西- Accounts.onLogin 具有参数用户对象 userObject 并且可以通过 userObject.user 访问用户详细信息，使用以下 -

Accounts.onLogin (userObject)->
 # userObject.user object can get you currently successful logged in user 
 console.log("login | onLogin")
 console.log("login | onLogin user:", userObject.user)
