我正在使用ExpressJS,NodeJS构建API
问题是当我使用Postman调用我的API时,我没有得到任何返回的结果。我不知道如何让Postman等待函数返回allproduct结果。我正在使用回调,但它只是不起作用,我在我的服务部分代码中尝试了许多简单的回调代码,但它们都没有工作。只有Async Await使Postman API停止并等待结果,但是我使用的是名为Pipedrive的第三方API,它只适用于回调。如果我能以某种方式使Pipedrive API与Async / Await一起工作,它可能会解决我的问题
路线:
var express = require('express')
var router = express.Router()
// Push the job to different controller functions
var PipedriveController = require('../../controllers/pipedrive.controller');
router.get('/products', PipedriveController.pipedriveAllProducts)
// Export the router
module.exports = router;
控制器
var PipedriveService = require('../services/pipedrive.service')
// Async Controller Function
exports.pipedriveAllProducts = async function(req, res, next){
// let family = req.param.options;
try {
let all_products = await PipedriveService.pipedriveAllProducts()
// Return All product liist with Appropriate HTTP header response
return res.status(200).json({status: 200, all_products});
} catch(e){
// Return an Error Response Message
return res.status(400).json({status: 400, message: e.message});
}
}
服务:
var Pipedrive = require('pipedrive');
var pipedrive = new Pipedrive.Client('SECRET', { strictMode: true });
// Saving the context of this module inside the _the variable
_this = this
exports.pipedriveAllProducts = async function operation(options){
// Array of product object - after which will be converted to JSON
const allproducts = [];
function iterateprods (err, products) {
if (err) throw err;
for (var i = 0; i < products.length; i++) {
// console.log(products[i].prices["0"].price);
let product = {
"id": products[i].code,
"name": products[i].name,
"price": products[i].prices["0"].price
}
allproducts.push(product)
}
console.log(JSON.stringify(allproducts));
return allproducts
}
pipedrive.Products.getAll({},iterateprods)
}
答案 0 :(得分:0)
首先,不需要在async
函数之前调整operation
,您需要将服务包含在承诺中,您可以执行以下操作:
var Pipedrive = require('pipedrive');
var pipedrive = new Pipedrive.Client('SECRET', { strictMode: true });
// Saving the context of this module inside the _the variable
_this = this
exports.pipedriveAllProducts = function operation(options){
// Array of product object - after which will be converted to JSON
const allproducts = [];
return new Promise((resolve, reject) => {
pipedrive.Products.getAll({}, function(err, products){
if (err) reject(err);
for (var i = 0; i < products.length; i++) {
// console.log(products[i].prices["0"].price);
let product = {
"id": products[i].code,
"name": products[i].name,
"price": products[i].prices["0"].price
}
allproducts.push(product)
}
console.log(JSON.stringify(allproducts));
resolve(allproducts);
});
}
