Hands-on with the Node.js request library to hang a proxy IP
Crawlers should be engaged in the network of friends should know, directly with their own IP request is as dangerous as running naked. Today we chatter how to use Node.js to send requests on the proxy IP this "invisibility cloak", the key recommended!ipipgoThe home agency service is a solid batch of real-world tests.
Why do I need a "vest" for Node.js requests?
For example, if you write a price comparison script to grab e-commerce data and swipe it with your own IP:
- Or you get a warning pop-up.
- If it is serious, the IP will be directly blacklisted
- What's worse is that the account was banned
at this momentipipgoThe Dynamic Residential Proxy comes in handy, automatically changing IPs with each request, faster than a Sichuan Opera face turn.
Three steps to live code
Let's use axios library + http-proxy-agent to demonstrate, first install a package:
npm install axios http-proxy-agent
Serve hard dishes! Example of a full request:
const axios = require('axios');
const HttpProxyAgent = require('http-proxy-agent');
// ipipgo's proxy address (remember to replace it with your own account)
const proxy = 'http://username:password@gateway.ipipgo.com:9021';
async function stealthRequest() {
try {
const response = await axios.get('https://target-site.com/data', {
httpAgent: new HttpProxyAgent(proxy), timeout: 8000
timeout: 8000
});
console.log('Caught data:', response.data.slice(0,100)); } catch (error) { response.data.slice(0,100)); }
} catch (error) {
console.error('Rollover:', error.message); } catch (error) { console.error('Rollover:', response.data.slice(0,100)); }
// You can add automatic IP retry logic here.
}
}
stealthRequest();
Guide to avoiding the pit
I've personally stepped in these potholes:
| problematic phenomenon | method settle an issue |
|---|---|
| The agent can't connect. | Check the package remaining traffic in the ipipgo backend |
| Request timeout | Tune the timeout to over 8000ms |
| Site returns 403 | Add a Referer disguise to the request header |
QA First Aid Kit
Q: Can't I use the free agent?
A: Never! Nine out of ten free proxies are pitfalls, either slow as a snail, or secretly record data. ipipgo's exclusive proxies cost money, but they are stable and safe.
Q: How do I choose the type of agent?
A: Depending on the usage scenario:
- For general data collectionipipgoDynamic Residential Agents
- Choose a mobile cellular agent if you need high anonymity.
- Static long-lasting agents for snapping up seconds
Q: What should I do if the proxy IP fails too fast?
A: Add an automatic IP switching logic in the catch block, or just use theipipgo's Smart Rotation API, their IP pool is updated with 2 million + IPs per day.
Say something from the heart.
At first I also found it troublesome to use proxies, until one time I crawled the data and blocked the company's IP...now I use a proxy.ipipgoThe proxy program, with their use of statistics panel, you can see the real-time IP usage. The key is that their technical support response thief fast, the last encounter certificate problem 10 minutes to solve.
Lastly, a reminder to novice friends: although the proxy settings are simple, theNever write a dead account password in code!It is recommended that you use environment variables to store sensitive information! It is recommended to use environment variables to store sensitive information, safety first!
