Data API: Data API interface service

What's the point of a data API interface anyway?

Brothers engaged in data collection know that now the site anti-climbing mechanism is more and more perverted. Last week I helped a friend get a commodity price comparison script, with their own broadband ran for two days on the IP blocked. At this timeProxy IP ServiceIt's like turning on a plug-in - switching to a different IP address to request data directly doubles the success rate.

As a solid example, crawl the price of an e-commerce platform with an ordinary IP:

import requests

url = 'https://example.com/api/products'
 Without a proxy, it's cool
response = requests.get(url)
print(response.status_code) Most likely to return 403

How do proxy IPs make data interfaces more stable?

Here's a trick for you:Dynamic rotation of IP poolsThe API service of ipipgo has a special feature, each request is automatically changed to a new IP. it's like playing a game of unlimited renewal, not afraid of being blocked.

The modified code looks like this:

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}

for _ in range(10).
    response = requests.get(url, proxies=proxies)
    print(f "This time using IP: {response.headers['X-Forwarded-For']}")

What are the doors to look for when choosing an agency service?

Agent services on the market are mixed, to teach you three tricks to avoid the pit guide:

Special mention to ipipgo'sIntelligent RoutingThe function can automatically select the fastest server node. It's like a taxi software that automatically dispatches orders without having to fiddle around.

Practical experience sharing

Last year, we helped a merchant to do price monitoring on double eleven, and we had to deal with 3000+ bans per day with ordinary proxy services. After switching to ipipgo.Request failure rate reduced from 42% to 5%. The point is that their home supports pay-per-use, so it doesn't hurt to use it for small projects.

One last rant:Don't buy a junk proxy on the cheap.The first thing you need to know is that you're not going to be able to use the same IP! Some service providers sell actually public proxy pools, dozens of people share the same IP, using it is worse than not using it. The difference between the regular army and the miscellaneous army can really save your life at critical moments.
