Puppeteer Agent Setup: Node.js Configuration

Hands-on teaching you to use Puppeteer with a proxy IP

Crawler brothers know that the use of Puppeteer to do automation often encountered IP blocked the bad things. Today we will chatter how to use ipipgo proxy service, to Node.js project to wear a "cloak".

Why do I need an agent vest for Puppeteer?

For example, if you let the program to go to a certain website every day, the result is that the IP is blocked every three days, if you give Puppeteer a proxy, it is like giving the program to wear a face mask, and every time you visit the program, you can change a new identity. ipipipgo proxy pool has millions of IP resources, especially suitable for this kind of need to frequently switch the scenarios.

Three Axes for Configuring Agents

First move: startup parameter assignment

const puppeteer = require('puppeteer');

async function run() {
  const browser = await puppeteer.launch({
    args: [
      '--proxy-server=http://username:password@ipipgo-proxy.com:8080'
    ]
  });
  //... Subsequent operations
}

Note that you have to change the username and password to the account you registered with ipipgo, and the port number depends on the specific package. If you're using a dynamic proxy, just replace the address with the API link they provide.

Tip #2: Separate settings for pages

const page = await browser.newPage();
await page.authenticate({
  authenticate({ username: 'ipipgo_user123', password: 'your_password')
  password: 'your_password'
}); await page.

This method is suitable for cases where different pages need to use different proxies, such as opening multiple pages at the same time to collect data.

Common Rollover Scene Handling

QA 1: What should I do if I can't connect to the agent?

First check if the network can ping the proxy server. If you use ipipgo's service, you can log into the backend to see the remaining traffic and expiration date. They have a real-time testing tool that can quickly troubleshoot if it's a code problem or a proxy problem.

QA 2: How do I know the proxy is really working?

await page.goto('http://ip.ipipgo.com/checkip'); const content = await page.content('http://ip.ipipgo.com/checkip');
const content = await page.content(); console.log(content); // This should display the proxy IP address.
console.log(content); // This should show the proxy IP.

Using this detection page, you can immediately see which IP is currently being used. it is recommended to do this check every time you start up to avoid using invalid proxies.

The unique advantages of ipipgo

Especially theirs.Dynamic Residential AgentsIt can simulate real user behavior when doing data collection, and it is more difficult to be identified than the IP of the server room. New user registration also send 1G flow trial, enough to run a small project.

Guide to avoiding the pit

1. Don't write the password explicitly in the code, it is recommended to use environment variables instead.

2. When an SSL certificate error is encountered, the startup parameter plus-ignore-certificate-errors

3. Long-time operation should be added to the proxy automatic switching mechanism, ipipgo's API support for the number of times / time to automatically change the IP

Lastly, do not just look at the price of choosing a proxy service. Like some free agents look at the cost-effective, the actual use of the three-day disconnect, delaying the progress of the project is really a big loss. Professional things or to ipipgo this kind of veteran service providers reliable, time-saving and worry.
