Meteor:在 Meteor.method 中调用异步函数并返回结果 [英] Meteor: Calling an asynchronous function inside a Meteor.method and returning the result

问题描述

我想在 Meteor 方法中调用一个异步函数，然后将该函数的结果返回给 Meteor.call.

(怎么)这可能?

Meteor.methods({我的功能:功能(arg1，arg2){//调用其他异步函数并返回结果或抛出错误}});

解决方案

Andrew Mao 是对的.Meteor 现在有 Meteor.wrapAsync() 用于这种情况.

这是通过条带进行充电并传递回调函数的最简单方法:

var stripe = StripeAPI("key");流星.方法({你的方法:函数(callArg){var charge = Meteor.wrapAsync(stripe.charges.create, stripe.charges);收费({金额:金额，货币:美元"，//我在callArg中传递了stripe token卡:callArg.stripeToken，}，功能(错误，收费){if (err && err.type === 'StripeCardError') {//该卡已被拒绝throw new Meteor.Error("stripe-charge-error", err.message);}//在此处插入您的成功"代码});}});

我发现这篇文章真的很有帮助:Meteor:在服务器上正确使用 Meteor.wrapAsync>

I want to call an asynchronous function inside a Meteor method and then return the result from that function to Meteor.call.

(How) is that possible?

Meteor.methods({
  my_function: function(arg1, arg2) {
    //Call other asynchronous function and return result or throw error
  }
});

解决方案

Andrew Mao is right. Meteor now has Meteor.wrapAsync() for this kind of situation.

Here's the simplest way to do a charge via stripe and also pass a callback function:

var stripe = StripeAPI("key");    
Meteor.methods({

    yourMethod: function(callArg) {

        var charge = Meteor.wrapAsync(stripe.charges.create, stripe.charges);
        charge({
            amount: amount,
            currency: "usd",
            //I passed the stripe token in callArg
            card: callArg.stripeToken,
        }, function(err, charge) {
            if (err && err.type === 'StripeCardError') {
              // The card has been declined
              throw new Meteor.Error("stripe-charge-error", err.message);
            }

            //Insert your 'on success' code here

        });
    }
});
