Accounts.onCreateUser 中的流星承诺 [英] Meteor Promises in Accounts.onCreateUser

问题描述

我想在用户注册期间创建一个条纹帐户，并为此目的调整 Accounts.onCreateUser 并承诺.

Accounts.onCreateUser((options, user) => {如果(user.services.facebook){const { first_name, last_name, email } = user.services.facebook;用户配置文件 = {}user.profile.first_name = first_nameuser.profile.last_name = last_name}别的{user.profile = options.profile}user.stripe = {}return new Promise((resolve,reject) => {stripe.customers.create({描述:user.profile.first_name + ' ' + user.profile.last_name}，函数(错误，响应){如果(！错误){user.stripe.id = response.id解决(用户)；} 别的 {拒绝('无法创建用户');}});})});

虽然在条带中正确创建了用户，但meteor mongo 数据库中的用户文档仅包含用户 ID，没有其他字段.

我是否使用了错误的承诺?任何帮助将不胜感激！

解决方案

因为 onCreateUser 在服务器上运行，我们可以使用 Meteor.wrapAsync 将 Stripe 调用包装在 Fiber 中>.

Fibers 允许异步代码像同步一样运行，但只能在服务器上运行.(这里有一个关于 Fiber 是什么以及 Meteor 为何使用它们的精彩演示)>

使用 wrapAsync 代码如下所示:

Accounts.onCreateUser((options, user) => {如果(user.services.facebook){const { first_name, last_name, email } = user.services.facebook;用户配置文件 = {}user.profile.first_name = first_nameuser.profile.last_name = last_name} 别的 {user.profile = options.profile}user.stripe = {};const createStripeCustomer = Meteor.wrapAsync(stripe.customers.create,stripe.customers);const 响应 = createStripeCustomer({描述:user.profile.first_name + ' ' + user.profile.last_name});user.stripe.id = response.id返回用户；});

I would like to create a stripe account during the user registration in meteor and adjusted Accounts.onCreateUser for that purpose with a promise.

Accounts.onCreateUser((options, user) => {
  if (user.services.facebook) {
    const { first_name, last_name, email } = user.services.facebook;
    user.profile = {}
    user.profile.first_name = first_name
    user.profile.last_name = last_name

  }
  else{
    user.profile = options.profile
  }
  user.stripe = {}
  return new Promise((resolve,reject) => {
    stripe.customers.create({
      description: user.profile.first_name + ' ' + user.profile.last_name
    },function(err,response){

        if (!err) {
          user.stripe.id = response.id
          resolve(user);
        } else {
          reject('Could not create user');
        }

    });
  })
});

While the user gets properly created in stripe, the user document in the meteor mongo database only contains the userid but no other field.

Am I using the promise wrong? Any help would be appreciated!

解决方案

Because onCreateUser runs on the server, we can wrap the Stripe call in a Fiber using Meteor.wrapAsync.

Fibers allow async code to run as though it was synchronous, but only on the server. (Here's a great presentation on what Fibers are and why Meteor uses them)

With wrapAsync the code looks like this:

Accounts.onCreateUser((options, user) => {
  if (user.services.facebook) {
    const { first_name, last_name, email } = user.services.facebook;
    user.profile = {}
    user.profile.first_name = first_name
    user.profile.last_name = last_name
  } else {
    user.profile = options.profile
  }

  user.stripe = {};
  const createStripeCustomer = Meteor.wrapAsync(stripe.customers.create,stripe.customers);
  const response = createStripeCustomer({
      description: user.profile.first_name + ' ' + user.profile.last_name
  });
  user.stripe.id = response.id
  return user;
});
