Intelligent booking system: real-time monitoring of hotel and airfares

Why do hotel airfares always change?

Folks booking tickets must have encountered this situation: yesterday good hotel prices, today and then brush up 200 dollars. Airlines are even more outrageous, the same flight at different times to check out the difference between a month's worth of meals. This matter is actually related toDynamic pricing systemsRelatedly, the back office of hotels and airline companies will monitor market demand in real time, just like a vegetable market will lower the price of vegetables in the afternoon.

Ordinary users manually refresh simply can not play the machine algorithm. A friend who does travel told me that their company uses crawler scripts to grab data a dozen times a minute, and the result is that the IP is blocked in three days. this time we need to use theproxy IPto cover up, as if giving a crawler program a cloak of invisibility.

The Pitfalls of Writing Your Own Monitoring Scripts

A lot of techies like to write their own crawlers, but often run into this crap:

 典型错误示范
import requests
url = "某旅行网站价格接口"
response = requests.get(url)  这样很快会被封

Using a single IP for high-frequency access is like picking up the same item over and over again at the supermarket, so who will the clerk stare at if not you? What's more, it's even more troublesome:

The right way to open a proxy IP

Here's what we recommendipipgoThe service is now available, and two things about his house are particularly good for price monitoring:

1. Dynamic Residential IP Pool: change IP automatically for each request, like the splitter in martial arts novels

2. Precise geographic locationSome hotels show different prices for users in different regions, so use your local IP to get the real quote.

 Example of correct configuration
import requests
from random import choice

proxies = ipipgo.get_proxy_pool() get dynamic IP pools
current_proxy = choice(proxies)

response = requests.get(
    url, current_proxies = choice(proxies)
    proxies={"http": current_proxy, "https": current_proxy},
    headers={"User-Agent": "Normal Browser ID"}
)

A practical guide to avoiding the pit

Name a few easy points to plant:

➊ Don't be too regular in your request intervals: Suggests random hibernation for 0.5-3 seconds to mimic a real person's operation

➋ User agents should be rotated: Don't always use Python's default UA, have 20 browser logos to rotate through!

➌ Pay attention to price accuracy: Some sites will show ¥699 as 6xx, you need to deal with special symbols!

Upgrade Play: Multi-Platform Price Comparison

Tips that the best of the best are using: monitoring the official website, OTA platforms and travel agency interfaces at the same time. Because:

• Certain Journey may give coupons to new users
• The official website often has exclusive prices for members
• Overseas platforms are more cost-effective to settle in US dollars

This is the time toipipgoThe multi-country IP service, such as using the Japanese IP to check the yen offer, and then use the Hong Kong IP to compare prices, and finally use the mainland IP to place an order, a set of operations down to save up to 30%.

Lastly, a reminder that price monitoring is not a panacea. When you encounter super low prices, you have to verify the inventory first, don't be like the last time a buddy grabbed 50 dollars for a five-star hotel, and as a result, when you arrived at the store, you were told that the system bugs do not recognize the account. Use the right tools + stay rational, in order to really woolgathering.
