Ionic cordova添加平台(错误:插座挂断)

Question

我正在创建一个带有离子框架的应用程序。之后，我通过cheerio scrape创建了一个API，并连接到heroku进行Hattp调用。问题是，在添加android平台时，我遇到了一个"套接字挂断"错误。我该如何着手解决这个问题？提前谢谢。这是我的代码：

//code server (index.js) 
const express = require("express");
const ok = require('./srabs')
const corsi = require('./corsiS')
const app = express();
const porta = '8000'
var cors = require('cors');
var https = require("https");



app.use(cors())

app.get('/', (req, res) => {
res.send(Array(ok.Arra, corsi.cors));

})



app.listen(process.env.PORT || 8000, () => {
console.log(`Server ex ${porta}`);
});



exports
//this is cheerio srcrape n1

const request = require('request');
const cheerio = require('cheerio');
const Arra = []
const arra2 = []


request('https://wwww.mywebsite.it/', (error, response, html) => {
// reset Array on each call

if (!error && response.statusCode == 200) {
const $ = cheerio.load(html)
const art = $('article').each((i, el) => {
const title = $(el)
.find('.entry-title.mh-posts-grid-title')
.text();
const link = $(el)
.find('a')
.attr('href');
const image = $(el).find('noscript').attr('data-img');



Arra.push({ title: [title], link: [link], image: [image] });

});
} 
} 
);
exports.Arra = Arra;
//this is cheerio srcrape n2

const request = require('request');
const cheerio = require('cheerio');
const KEY_aff = '/?ffverf4fergtrrgefe12321b'
const cors = []



request('https://curses.it/courses', (error, response, html) => {
// reset Array on each call

if (!error && response.statusCode == 200) {
const $ = cheerio.load(html);
const art = $('.course-listing').each((i, el) => {
const img = $(el).find('.course-box-image-container')
.find('img')
.attr('src');
const link = $(el)
.find('a').attr('href')


var http = 'https://curses.it' + link + KEY_aff;

const title = $(el).find('.course-listing-title').text();
const subtitle = $(el).find('.course-listing-subtitle').text();

cors.push({ title: [title], sub: [subtitle], linkAF: [http], img: [img] });

})
}
}),
exports.cors = cors;
//this is error in terminal of ionic

我解决了它，它不是API问题。我刚刚重新安装了的依赖项：node.js，离子，crodova-res.
