Flight Data Collection Tool: Real-time Airfare Monitoring

How to capture flight data? Proxy IP helps you

Recently, many friends asked how to do airfare monitoring tool, today we nag some real. Do real-time airfare monitoring is the most headacheIP blockedIf the website realizes that you are constantly checking prices, it will pull your IP in minutes. This is the time to use a proxy IP tofight a guerrilla warThe Monkey King is like the Monkey King pulling out hairs to change into countless doppelgängers.

Why do I have to use a proxy IP?

Airline websites are equipped with "electronic security", the same IP frequent visits immediately alarm. Last week, a buddy did not believe in the evil and used his own server to capture, and the next day the whole server room IP was blocked. Proxy IP can realize three key effects:

• IP addresses change all the time, like in Sichuan opera.
• The frequency of visits can be adjusted higher (not too much, of course)
• Ability to disguise as a user in a different region to check prices

How to choose a reliable proxy IP?

There are many proxy IP service providers on the market, but we have to pick one that can handle the job. RecommendedipipgoHome services, they have three tricks up their sleeve:

Here's the kicker.IP type selection: Catch airline websites with residential IPs, not server room IPs. Airlines are particularly sensitive to data center IPs, and residential IPs look like real users and are not easily recognized.

Hands On Configuration

Here's a Python example, using the requests library + ipipgo proxy:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'https://用户名:密码@gateway.ipipgo.com:9020'
}

url = 'https://航空公司官网/机票查询接口'
headers = {'User-Agent': 'Mozilla/5.0 proper browser UA'}

try.
    response = requests.get(url, proxies=proxies, headers=headers, timeout=8)
    print(response.text)
except Exception as e.
    print(f "Crawl error: {str(e)}")

Watch out for two potholes.① timeout time is not set too short, it is recommended that 6-8 seconds ② remember to randomly switch User-Agent, just change the IP is not enough!

A practical guide to avoiding the pit

I stepped on a mine last year helping a travel agency with a monitoring system:

1. Don't write a dead proxy IP in the code, use ipipgo's API to get it dynamically!
2. Don't fight with CAPTCHA, it's more cost-effective to change IP and retry than cracking it
3. The collection interval can be shortened from 1-5am, when there are fewer people checking tickets

Frequently Asked Questions QA

Q: What should I do if I am always prompted for frequent visits?
A: Change the collection interval from 30 seconds to 45-120 seconds randomly, and at the same time check if you are using a low-quality proxy IP. ipipgo users can contact customer service to open the "high stash mode".

Q: What should I do if the slow response of proxy IP affects the collection?
A: ① choose ipipgo's exclusive air ticket collection channel ② set the timeout to automatically switch IP ③ set the number of retries to 3 times

Q: What's wrong with incomplete data capture?
A: Eighty percent of the site revamped, remember to check the crawl rules every week. Use ipipgo'sPage change monitoringfunction that automatically alerts you to rule expirations

Finally, a piece of cold knowledge: some airlines have a strange price caching mechanism, continuous use of the same city IP check instead of getting outdated data. This time, use ipipgo'sCross-city pollingFunctions that can keep the data up to date with fast cooked 30% or more.
