Apollo Server：如何根据回调发送响应？

Question

我目前正在尝试使用此软件包验证 iOS 应用内购买的收据：https://github.com/Wizcorp/node-iap

这是我不完整的解析器：

export default {
  Query: {
    isSubscribed: combineResolvers(
      isAuthenticated,
      async (parent, args, { models, currentUser }) => {
        const subscription = await models.Subscription.find({ user: currentUser.id });

        const payment = {
          ...
        };

        iap.verifyPayment(subscription.platform, payment, (error, response) => {
          /* How do I return a response here if it is async and I don't have the response object? */
        });
      }
    ),
  },
};

如果响应是异步的并且我没有响应对象，我如何 return 在此处响应？通常，我只是习惯 returning 任何模型 returns。但是，这次我使用的是 node-iap，它是基于回调的。

您可以使用 Promise：

const response = await new Promise((resolve, reject) => {
  iap.verifyPayment(subscription.platform, payment, (error, response) => {
    if(error){
      reject(error);
    }else{
      resolve(response);
    }
  });
});
