Question

我正在尝试添加一个简单的处理程序来处理登录时的用户。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)

但这永远不会到达第二个console.log。

如果我发表评论user = Meteor.user()，那么它就不会崩溃。

是否可以通过这种方式从服务器端流星获取currentUser？

对于客户端我可以用跟踪器收听，但我更愿意在回调事件和服务器端使用它。 https://stackoverflow.com/a/16353336/1146785

奇怪的是错误总是引用Meteor.userId（），即使我没有调用它。

你在这里遗漏了一些东西 - Accounts.onLogin具有参数用户对象userObject，用户详细信息可以通过userObject.user访问，请使用以下内容 -

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)
