如何只制作注册邀请? [英] How to make sign-up invitation only?

问题描述

使用 Meteor 帐户(和 accounts-ui)是否有一种简单的方法可以仅邀请新用户注册?例如通过提供邀请链接或邀请代码.

Using Meteor accounts (and accounts-ui) is there an easy way to make new user sign-ups invitation only? For example by providing an invitation link or an invitation code.

我在 Meteor 文档中唯一能找到的相关内容是 Meteor.sendEnrollmentEmail，但它并没有解决我的问题.

The only thing related I could find in the Meteor documentation is Meteor.sendEnrollmentEmail but it doesn't solve my problem.

推荐答案

你可以用内置的包来做到这一点，但我发现滚动一个简单的实现更容易和强大.

You can do this with the built in package, but I found it alot easier and powerful to roll a simple implementation.

您需要:

• 创建一个集合，例如 UserInvitations 以包含成为用户的邀请.
• 创建用于制作 UserInvitations 的 UI/插入一些使用 meteor mongo

• 使用 iron-router 或类似方法创建路由，例如:

• Create a collection, eg UserInvitations to contain the invites to become a user.
• Create UI for making UserInvitations / insert some using meteor mongo

• Using iron-router or similar create a route, eg:

Router.map ->
  @route 'register',
    path: '/register/:invitationId'
    template: 'userRegistration'
    data: ->
      return {
        invitationId: @params.invitationId
      }
    onBeforeAction: ->
      if Meteor.userId()?
        Router.go('home')
      return

当userRegistration中的表单被提交时——调用

When the form in userRegistration is submitted - call

Accounts.createUser({invitationId: Template.instance().data.invitationId /*,.. other fields */})

在服务器上，创建一个 Accounts.onCreateUser 钩子以将 invitationId 从选项传递给用户

On the server, make an Accounts.onCreateUser hook to pass through the invitationId from options to the user

Accounts.onCreateUser(function(options, user){
  user.invitationId = options.invitationId
  return user;
});

此外，在服务器上创建一个 Accounts.validateNewUser 钩子来检查 invitationId 并将邀请标记为已使用

Also, on the server make an Accounts.validateNewUser hook to check the invitationId and mark the invitation as used

Accounts.validateNewUser(function(user){
  check(user.invitationId, String);
  // validate invitation
  invitation = UserInvitations.findOne({_id: user.invitationId, used: false});
  if (!invitation){
    throw new Meteor.Error(403, "Please provide a valid invitation");
  }
  // prevent the token being re-used.
  UserInvitations.update({_id: user.invitationId, used: false}, {$set: {used: true}});

  return true
});

现在，只有拥有有效未使用的 invitationId 的用户才能注册.

Now, only users that have a valid unused invitationId can register.
