Any existing sample on how to use puppeteer with nordVpn ?
I tried that:
page = await browser.newPage();
await useProxy(page, `socks5://login:password}#fr806.nordvpn.com:1080`);
I also tried:
'--proxy-server=socks5://login:password#fr806.nordvpn.com:1080'
This script works, you need to change the user/pass to yours... these are not your Nord user/pass... you need to get the service/api ones from in your account settings. Change the server to whatever one you need to use.
#!/usr/bin/env node
// Screengrab generator
// outputs a JSON object with a base64 encoded image of the screengrab
// eg;
const puppeteer = require('puppeteer');
let conf = new Object();
conf.url = "https://www.telegraph.co.uk";
// VPN
conf.vpnUser = conf.vpnUSer || 'USERNAME';
conf.vpnPass = conf.vpnPass || 'PASSWORD';
conf.vpnServer = conf.vpnServer || "https://uk1785.nordvpn.com:89";
(async() => {
const browser = await puppeteer.launch({
headless: true,
args: [
'--disable-dev-shm-usage',
'--proxy-server='+conf.vpnServer
]
});
try {
const page = await browser.newPage();
await page.authenticate({
username: conf.vpnUser,
password: conf.vpnPass,
});
await page.goto(conf.url, { waitUntil: 'networkidle2' });
} catch (error) {
console.error(error);
} finally {
await browser.close();
}
})();

When using a proxy for my puppeteer request to scrape a page, some data is missing such as price but the rest is there. When I remove the proxy, everything loads correctly.
const getData = async () => {
const browser = await puppeteer.launch({
headless: true,
args: ["--no-sandbox", "--disable-setuid-sandbox", "--ignore-certificate-errors", "--proxy-server=myproxy"],
});
const page = await browser.newPage();
await page.authenticate({ username: "username", password: "password" });
await page.goto(url, {
timeout: 300000,
waitUntil: "load",
});
const html = await page.evaluate(() => document.body.innerHTML);
const $ = cheerio.load(html);
const products = [];
$("[data-automation=product-results] > div").each((index, el) => {
const id = product.attr("data-product-id");
const name = product.find("[data-automation=name]").text();
const image = product.find("[data-automation=image]").attr("src");
const price = product.find("[data-automation=current-price]").text();
const data = {
id,
name,
image,
price,
};
products.push(data);
});
console.log(products);
};
I have tried: waitUntil: 'domcontentloaded' (same results), waitUntil: 'networkidle0' and waitUntil: 'networkidle2' both times out (5 minutes).
I don't quite understand why I am able to get all the data without using a proxy and only get partial data using a proxy.
Hi Guys can you please point my mistake on this code?
console.log(urls) is printing undefined.
Thanks in advance.
const puppeteer = require('puppeteer');
async function GetUrls() {
const browser = await puppeteer.launch( { headless: false,
executablePath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe' })
const page = await browser.newPage();
await page.goto("https://some page");
await page.waitForSelector('a.review.exclick');
let urls = await page.evaluate(() => {
let results = [];
let items = document.querySelectorAll('a.review.exclick');
items.forEach((item) => {
results.push({
url: item.getAttribute('href'),
});
});
return results;
browser.close();
});
}
(async () => {
let URLS = await GetUrls();
console.log(URLS);
process.exit(1);
})();
Here is a list:
you don't have a return statement in your GetUrls() function
you close the browser after a return statement AND inside the page.evaluate() method
Keep in mind that anything that is executed within the page.evaluate() will relate to the browser context. To quickly test this, add a console.log("test") before let results = []; and you will notice that nothing appears in your Node.js console, it will appear in your browser console instead.
Therefore, the browser variable is visible within the GetUrls() function but NOT visible within the page.evaluate() method.
Here is the corrected code sample:
const puppeteer = require('puppeteer');
async function GetUrls() {
const browser = await puppeteer.launch({
headless: false,
executablePath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe'
})
const page = await browser.newPage();
await page.goto("https://some page");
await page.waitForSelector('a.review.exclick');
let urls = await page.evaluate(() => {
let results = [];
let items = document.querySelectorAll('a.review.exclick');
items.forEach((item) => {
results.push({
url: item.getAttribute('href'),
});
});
return results;
});
await browser.close();
return urls;
}
(async () => {
let URLS = await GetUrls();
console.log(URLS);
process.exit(1);
})();
I'm trying to submit a login form, but all I get is a timeout after 30 seconds.
My code is rather simple and I can't find anything wrong:
const puppeteer = require('puppeteer');
const creds = {
user: "1234",
password: "1234"
};
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setViewport({width: 1280, height: 800});
await page.goto('https://shop2.idena.de/NewShop/');
await page.type('input[name="FORM_LOGIN"]', creds.user);
await page.type('input[name="FORM_PASSWD"]', creds.password);
await Promise.all([
page.click('button[name="FORM_TYPE"]'),
page.waitForNavigation()
]);
await page.screenshot({path: 'example.png', fullPage: true});
await browser.close();
})();
Any ideas what's going wrong here?
Change the order of the promises a bit, it could be possible, the navigation happens super fast and the waitForNavigation is just waiting for nothing. Or maybe your website loads very slow after clicking the login button.
await Promise.all([
page.waitForNavigation({timeout: 60000}),
page.click('button[name="FORM_TYPE"]'),
]);
If I use your example with headful option, I get this dialog that prevents the page from loading:
So this addition can help (not sure if some dialog emerges with correct credentials):
const puppeteer = require('puppeteer');
const creds = {
user: "1234",
password: "1234"
};
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setViewport({width: 1280, height: 800});
await page.goto('https://shop2.idena.de/NewShop/');
await page.type('input[name="FORM_LOGIN"]', creds.user);
await page.type('input[name="FORM_PASSWD"]', creds.password);
page.on('dialog', async dialog => {
console.log(dialog.message());
await dialog.accept();
});
await Promise.all([
page.click('button[name="FORM_TYPE"]'),
page.waitForNavigation()
]);
await page.screenshot({path: 'example.png', fullPage: true});
await browser.close();
})();
EDIT: I'm updating my answer since more infomration has been provided in the original question.
The problem is that there's a dialog you need to confirm/dismiss:
Perhaps you didn't see it because the script was too fast. I recommend debugging puppeteer scripts with headless set to false and slowMo to some number greater than 0:
const browser = await puppeteer.launch({ headless: false, slowMo: 200 });
Then you need to get rid of the dialog:
page.on('dialog', async (dialog) => {
await dialog.accept();
});
The whole script that now passes:
const puppeteer = require('puppeteer');
const creds = {
user: "1234",
password: "1234"
};
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setViewport({width: 1280, height: 800});
await page.goto('https://shop2.idena.de/NewShop/');
await page.type('input[name="FORM_LOGIN"]', creds.user);
await page.type('input[name="FORM_PASSWD"]', creds.password);
page.on('dialog', async (dialog) => {
await dialog.accept();
});
await Promise.all([
page.click('button[name="FORM_TYPE"]'),
page.waitForNavigation()
]);
await page.screenshot({path: 'example.png', fullPage: true});
await browser.close();
})();
I am currently doing a project that needs to scrape a data from the search result in carousell.ph
I basically made a sample HTML and replicate the output HTML of carousell, so far the javascript work except when I tried to migrate it using puppeteer it always gives me an error.
The task is basically get all the product list from the search url "https://www.carousell.ph/search/iphone"
Here's the code I made.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch()
const page = await browser.newPage()
let url = 'https://www.carousell.ph/search/iphone';
await page.goto(url, {waitUntil: 'load', timeout: 10000});
await page.setViewport({ width: 2195, height: 1093 });
await page.screenshot({ fullPage: true, path: 'carousell.png' });
document.querySelectorAll('main').forEach(main => {
main.querySelectorAll('a').forEach(product => {
const product_details = product.querySelectorAll('p');
const productName = product.textContent;
const productHref = product.getAttribute('href');
console.log(product_details[0].textContent + " - "+ product_details[1].textContent);
});
});
await browser.close()
})()
As #hardkoded stated, document is not something that is out of the box in puppeteer, it's dogma in the browser, but not in Node.js. You also do not need to for each in Node.js. The Map Technique outlined in this video is very helpful and quick. I'd make sure also to keep await on your loop or map technique, because the function is asynchronous so you want to make sure the promise comes back resolved.
Map technique
An extremely fast way to get many elements into an array from a page is to use a function like below. So instead of getting an array of the elements and then looping them for their properties. You can create a function like this below using $$eval and map. The result is a formatted JSON array that takes all the looping out of the equation.
const links = await first_state_list.$$eval("li.stateList__item", links =>
links.map(ele2 => ({
State_nme: ele2.querySelector("a").innerText.trim(), //GET INNER TEXT
State_url: ele2.querySelector("a").getAttribute("href") //get the HREF
}))
);
Already made it work.
const puppeteer = require('puppeteer');
async function timeout(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
(async () => {
const browser = await puppeteer.launch()
const page = await browser.newPage();
let searchItem = 'k20&20pro';
let carousellURL = 'https://www.carousell.ph/search/' + searchItem;
await page.goto(carousellURL, {waitUntil: 'load', timeout: 100000});
//await page.goto(carousellURL, {waitUntil: 'networkidle0'});
await page.setViewport({
width: 2195,
height: 1093
});
await page.evaluate(() => {
window.scrollBy(0, window.innerHeight);
})
await timeout(15000);
await page.screenshot({
fullPage: true,
path: 'carousell.png'
});
var data = await page.evaluate(() =>
Array.from(
document.querySelectorAll('main div a:nth-child(2)')).map(products => products.href
)
)
var i;
for (i = 0; i < data.length; i++) {
console.log(data[i]);
// comment this section but this will open the page to get product details.
//await page.goto(data[1], {"waitUntil" : "networkidle0"});
// inner product page details
// this will get the title
// document.querySelectorAll('h1')[0].innerText;
// this will get the amount
// document.querySelectorAll('h2')[0].innerText;
// this will get the description
// document.querySelectorAll('section div div:nth-child(4) p')[0].innerText;
// this will get sellers name
// document.querySelectorAll('div div:nth-child(2) a p')[0].innerText;
let ss_filename = 'carousellph_'+searchItem+'_'+i+'.png';
console.log(ss_filename);
console.log("\r\n");
//await page.screenshot({ fullPage: false, path: ss_filename });
}
await browser.close()
})()
I'm new to puppeteer and node, trying to use a proxy with puppeteer in order to collect requests & responses, hopefully also websocket communication, but so far couldn't get anything to work..
I'm trying the following code:
const puppeteer = require('puppeteer');
const httpProxy = require('http-proxy');
const url = require('url');
let runProxy = async ()=> {
// raise a proxy and start collecting req.url/response.statusCode
};
let run = async () => {
await runProxy();
const browser = await puppeteer.launch({
headless: false,
args: ['--start-fullscreen',
'--proxy-server=localhost:8096']
});
page = await browser.newPage();
await page.setViewport({ width: 1920, height: 1080 });
await page.goto('http://www.google.com',
{waitUntil: 'networkidle2', timeout: 120000});
};
run();
I've tried some variation from https://github.com/nodejitsu/node-http-proxy but nothing seems to work for me, some guidance is at need, thanks
try this, use https-proxy-agent or http-proxy-agent to proxy request for per page:
import {Job, Launcher, OnStart, PuppeteerUtil, PuppeteerWorkerFactory} from "../..";
import {Page} from "puppeteer";
class TestTask {
#OnStart({
urls: [
"https://www.google.com",
"https://www.baidu.com",
"https://www.bilibili.com",
],
workerFactory: PuppeteerWorkerFactory
})
async onStart(page: Page, job: Job) {
await PuppeteerUtil.defaultViewPort(page);
await PuppeteerUtil.useProxy(page, "http://127.0.0.1:2007");
await page.goto(job.url);
console.log(await page.evaluate(() => document.title));
}
}
#Launcher({
workplace: __dirname + "/workplace",
tasks: [
TestTask
],
workerFactorys: [
new PuppeteerWorkerFactory({
headless: false,
devtools: true
})
]
})
class App {}
