邮递员在发出 node.js 请求时挂起

Question

I'm using postman to make a request to my node.js API, to which I'm using my orders route to send a request following my order controller. Whatever requisition I make using my orders route my requisition hangs and instead of receiving either a 400 or a 500 response, my postman gets stuck on loading screen and it times out after some time. I tried alternatively using the google chrome extension, same results. After the requisition is unsuccessful I receive the following message

I was wondering if it has something to do with how I did the routing in my backend, but I am unsure of this. Hence, here's my code:

model.js:

'use strict';

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const schema = new Schema({
    customer: {
        type: mongoose.Schema.Types.ObjectId,
        ref: 'Customer'
    },
    number: {
        type: String,
        required: true
    },
    createDate: {
        type: Date,
        required: true,
        default: Date.now
    },
    status: {
        type: String,
        required: true,
        enum: ['created', 'done'],
        default: 'created'
    },
    items: [{
        quantity: {
            type: Number,
            required: true,
            default: 1
        },
        price: {
            type: Number,
            required: true
        },
        product: {
            type: mongoose.Schema.Types.ObjectId,
            ref: 'Product'
        }
    }],
});

module.exports = mongoose.model('Order', schema);

post method in my order-controller.js:

exports.post = async(req, res, next) => {
    try {
        const token = req.body.token || req.query.token || req.headers['x-access-token'];
        const data = await authService.decodeToken(token);

        await repository.create({
            customer: data.id,
            number: guid.raw().substring(0, 6),
            items: req.body.items
        });
        res.status(201).send({
            message: 'Order registered with success!'
        });
    } catch (e) {
        console.log(e);
        res.status(500).send({
            message: 'Fail to process your requisition'
        });
    }
};

order-repository.js:

'use strict';
const mongoose = require('mongoose');
const Order = mongoose.model('Order');

exports.get = async(data) => {
    var res = await Order
        .find({}, 'number status customer items')
        .populate('customer', 'name')
        .populate('items.product', 'title');
    return res;
}

exports.create = async(data) => {
    var order = new Order(data);
    await order.save();
}

order-route.js:

'use strict';

const express = require('express');
const router = express.Router();
const controller = require('../controllers/order-controller');
const authService = require('../services/auth-service');

router.get('/', authService.authorize, controller.get);
router.post('/', authService.authorize, controller.post);

module.exports = router;

Answer 1

This can happen if you are debugging your nodejs server and it's caught on a breakpoint. If so, the response will hang. To fix it, just disable that breakpoint, restart your nodejs server, and issue the request again with Postman.

Answer 2

Maybe you are using a GET request in the postman instead of POST request. Make sure that they comply with the type.
