JavaScript Web Page Capture: JS Web Page Capture Proxy Settings

First, why use a proxy IP to engage in web crawling?

The old iron engaged in data collection know that the website anti-climbing mechanism is becoming more and more ruthless. For example, when loading data with JS, the same IP frequent requests are blacked out in minutes. At this time it is necessary to rely onProxy IP Rotationto masquerade as different users, especially with ipipgo's Residential Proxy, which can simulate real user network environments.

For example, an e-commerce site blocks 2,000+ crawler IPs per hour, and if you use an ordinary server IP, you may be cool in half an hour. But with a dynamic residential IP pool, each request for a different exit IP, the survival rate directly pull full.

Second, JS crawl agent configuration three-piece suite

Here to the guys whole a few common scenarios of the proxy setting method, according to copy the homework on the line:

// Axios version (Node.js environment)
const axios = require('axios');
const proxy = {
  host: 'gw.ipipgo.com',
  port: 9021,
  auth: {
    username: 'Your account',
    password: 'API key'
  }
}

axios.get('Target URL', {proxy})
  .then(response => console.log(response.data))

// Puppeteer version (browser environment)
const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({
    args: [
      '--proxy-server=socks5://gw.ipipgo.com:1080',
      '--disable-blink-features=AutomationControlled'
    ]
  });
  const page = await browser.newPage();
  await page.authenticate({
    authenticate({ username: 'account name', password: 'password'); await browser.newPage(); await page.
    password: 'password'
  }); await page.authenticate({ username: 'account name', password: 'password'); }
})();

Third, avoid the pit guide to see here

These moths are common in real-world testing:

IV. QA First Aid Kit

Q: What can I do about slow proxy IPs?
A: change to use ipipgo static residential IP, 35 dollars a month that, specializing in a variety of loading slow

Q: What if I want to capture a website that requires a login?
A: Bind a fixed account with an exclusive IP to avoid triggering the wind control of off-site login

Q: How to use the IP extracted by API?
A: Directly tune ipipgo's interface to get the IP list, it is recommended to randomly select an IP before each request.

Fifth, how to choose packages do not step on mine

Match the business scenario to the business scenario:

• Dynamic residential (standard): Suitable for small-scale collection, $7.67/G real incense price
• Dynamic Residential (Business): Required when high concurrency is needed, with exclusive API channel
• Static homes: A must for long-term assignments, with IP survival cycles of over 30 days

Lastly, I'd like to say, don't use the free proxy for data collection, nine out of ten of those things are pits. How about spending a little money with ipipgo's reliable service, save time to jerk skewers do not smell good? There are special needs can also find their technical brother to get customized solutions, than their own toss much stronger.
