Proxy IP combined with Puppeteer Page Load Waiting: Proxy IP Puppeteer Load Optimization

How does the pairing of Proxy IP and Puppeteer work?

Anyone who has done web automation knows that Puppeteer is like a robot that helps you automate your browser. However, if you use it naked, you will often encounterPinched for visiting too oftenof embarrassment. This is the time to give the robotchange clothes--that is, using a proxy IP to disguise your identity.

Let's take our ipipgo proxy as a chestnut, suppose you want to collect data from a certain website in bulk. If you use Puppeteer alone, you may get your IP blocked if you visit it more than 10 times in a row. If each visit to change a new suit (different proxy IP), the other site can not tell whether the operation of the real person or machine running.

const puppeteer = require('puppeteer');
const proxy = 'http://username:password@ipipgo-proxy-server:8080'; //proxy format provided by ipipgo

async function run(){
  const browser = await puppeteer.launch({
    args: [`--proxy-server=${proxy}`]
  });
  //... Subsequent operations
}

How do I load a proxy IP into Puppeteer?

Here are three practical tricks to teach you:

Focusing on the first method, when using ipipgo's proxy, pay attention to theirdynamic password authenticationMechanism. Many newbies will fall into this pit and directly write the account password to death in the code. The right posture is to use the API they provide to dynamically get the authentication information, like this:

const getProxy = async () => {
  const res = await fetch('https://api.ipipgo.com/getproxy');
  return `http://${res.data.proxy}`;
}
// Get a new proxy before each browser start

How do I break the loading lag?

After putting on the proxy, sometimes it will become turtle speed, here to share a few real test effective acceleration techniques:

1. prioritizeDedicated Static IP(ipipgo's package B has this service)
2. Set a reasonable timeout and don't wait around!
3. Disable unnecessary resource loading

Setting it up like this saves a lot of time, for example:

await page.setRequestInterception(true);
page.on('request', req => {
  if(['image','stylesheet'].includes(req.resourceType())){
    req.abort();
  } else {
    req.continue();
  }
}).

Frequently Asked Questions QA

Q: What should I do if the agent often fails to connect?
A: Check the authentication information format first, ipipgo's proxy needs to be used with theusername:password@ip:portformat. If that doesn't work, contact their customer service for an alternate server address.

Q: What should I do if the page doesn't load fully?
A: Try adjusting your waiting strategy, don't use a deadbeatpage.waitForTimeout()Switching topage.waitForSelector()and other elemental detection methods.

Q: What if I need a multi-region IP?
A: Directly on ipipgo'sCity-level agent poolWhen selecting the IP, just specify the region parameter, for example, if you want the Shanghai IP to passcity=shanghaiThe

Lastly, don't just look at the price when choosing a proxy service. Some of the free proxies look cheap, but in reality, they are not as good as they look.be disconnected for three daysThe agent of ipipgo, although it costs money, but it is stable and reliable, especially if you are doing serious projects, don't lose a lot of money by saving a small amount of money in this area.
