Wrapping Stripe 在 Meteor 的 Fibers 中创建客户回调 [英] Wrapping Stripe create customer callbacks in Fibers in Meteor

问题描述

我在创建新客户时无法让 Stripe.js 正常工作.这是他们教程中的 Node.js 代码:

I'm having trouble getting Stripe.js to work when creating a new customer. Here is their Node.js code in their tutorial:

// Set your secret key: remember to change this to your live secret key in production
// See your keys here https://dashboard.stripe.com/account/apikeys
var stripe = require("stripe")("sk_test_9999999999999999999999");

// (Assuming you're using express - expressjs.com)
// Get the credit card details submitted by the form
var stripeToken = request.body.stripeToken;

stripe.customers.create({
  source: stripeToken,
  description: '[e-mail]'
}).then(function(customer) {
  return stripe.charges.create({
    amount: 1000, // amount in cents, again
    currency: "usd",
    customer: customer.id
  });
}).then(function(charge) {
  saveStripeCustomerId(user, charge.customer);
});

这是我的尝试.我将所有回调都封装在 Meteor.bindEnvironment 中，因为异步回调需要在纤程中运行.我在服务器控制台中收到错误消息:

This is my attempt. I wrapped all the callbacks in Meteor.bindEnvironment because async callbacks need to run in a fiber. I get an error in the server console:

Exception while invoking method 'submitOrder' Error: Stripe: Unknown arguments (function (/* arguments */) {  

有人能指出我用纤维包裹它的正确方向吗?还是使用 Meteor.wrapAsync?

Can anyone point me in the right direction for wrapping this in fibers? Or utilizing Meteor.wrapAsync?

var createStripeCustomer = function(ShoppingCartObject){
    check(ShoppingCartObject, Object);
    var stripe = Stripe("sk_test_9999999999999999");
    // (Assuming you're using express - expressjs.com)
    // Get the credit card details submitted by the form
    var stripeToken = ShoppingCartObject.charge.token;

    stripe.customers.create(
        {
          source: stripeToken,
          description: ShoppingCartObject._id,
          email: ShoppingCartObject.customerInfo.agentEmail,
        }, 
        Meteor.bindEnvironment(function(customer){
            return stripe.charges.create({
            amount: ShoppingCartObject.totalPrice, // amount in cents, again
            currency: "usd",
            customer: customer.id
            });
        }), 
        Meteor.bindEnvironment(function(charge){
            ShoppingCartObject.charge.customer = charge.customer;
            submitOrder(ShoppingCartObject);
        })
    );
};

var submitOrder = function(ShoppingCartObject){
  check(ShoppingCartObject, Object);
  var data = _.omit(ShoppingCartObject, '_id');
  var setHash = { $set: data };
  ShoppingCarts.update({_id: ShoppingCartObject._id}, setHash);
};

推荐答案

这是对我有用的方法的简化版本.我基本上为每个 Stripe 调用创建了一个返回 Future 的函数.

Here is a simplified version of an approach that has worked for me. I basically create a function for each Stripe call that returns a Future.

// Server

var Future = Npm.require('fibers/future');

function createCustomer(token){
    var future = new Future;
    Stripe.customers.create({
      card: token.id,
      email: token.email
    }, function(error, result){
      if (error){
        future.return(error);
      } else {
        future.return(result);
      }
    });
    return future.wait();
  }

Meteor.methods({
  purchase: function(token){
    check(token: Object);
    try {
      var customer = createCustomer(token);
    } catch(error) {
      // error handle
    }
    // create charge, etc. repeating same pattern
  }
});
