Proxy IP data crawling strategy: data crawling proxy strategy optimization

Why do you always get blocked for data crawling? Let's see what you're missing.

Recently, many of my friends who do data collection have been complaining to me, saying that now the website is getting more and more ruthless in anti-climbing. Last month, the old king to do e-commerce price monitoring, just grabbed 2000 pieces of data IP was blocked, and he was so angry that he straight shot the keyboard. In fact, this matter, with fishing a reason - always use the same rod in the same position fishing, fish early learning.

Let's take a real example: a ticketing platform detects the same IP request more than 50 times per hour and then pulls the black. If you don't use a proxy IP hard, but not last half a day quasi break. This time you have to learn guerrilla warfare.lit. shoot one shot and move to another location (idiom); fig. to make a clean sweep, leaving the anti-crawl system puzzled.

Three Tough Tips to Teach You to Play with Proxy IPs

The first move: the combination of movement and static works wonders

Dynamic IPs are like mobile vendors, suitable for high-frequency crawling as they are used. Static IP is like a fixed store, which is suitable for the scenarios that need to keep the session. For example, if the data can only be captured after logging in, first log in with dynamic IP, change to static IP to keep the session, and finally cut back to dynamic to continue to capture.

import requests
from ipipgo_client import get_proxy hypothetical ipipgo client library

 Get dynamic proxy
dynamic_proxy = get_proxy(type='dynamic')
login_session = requests.
login_session.proxies = {"http": dynamic_proxy}

 Toggle static proxies to maintain the session
static_proxy = get_proxy(type='static')
data_scraper = requests.Session()
data_scraper.proxies = {"http": static_proxy}

Tip #2: There's a way to distribute traffic

Don't try to use a single IP, it's recommended to assign it this way:

Tip #3: Keep up with camouflage techniques

It's not enough to change IPs, you have to learnpretend to be normal::
1. Random User-Agent do not use existing libraries, maintain a list of their own
2. Don't be too regular with mouse trajectory simulation
3. Don't make the visit interval look like a stopwatch, add some random jitter.

A guide to stepping on the pit in real life (with solutions)

Pitfall 1: Sudden cut-off of the proxy pool
Last month a platform was doing an event and the proxy IP provider suddenly dropped the ball. Later changed to ipipgoDedicated Static IP Package, support API real-time replenishment of the IP pool, and then no more problems.

Pothole 2: HTTPS certificate reporting errors
Some proxies will trigger SSL authentication, adding a verify=False parameter in the requests request can be an emergency, but in the long run it is recommended to use a proxy service that supports native HTTPS.

question-and-answer session

Q: What can I do about slow proxy IPs?
A: Prioritize local operator resources, such as doing domestic collection with ipipgoTK LineThe measured latency can be squeezed to within 200ms.

Q: How do I choose a package for my enterprise level needs?
A: The average daily data volume exceeds 50GB, directly on ipipgo'sDynamic Residential (Enterprise Edition)It is much more stable than the standard version, with dedicated channels and automatic expansion of traffic pools.

the right tool saves effort and leads better results

I've used 7 or 8 agencies and finally settled on ipipgo for three main reasons:
1. Dynamic or static, but also mixed
2. Transparent price, no tricks, 35 dollars can use a static residential IP
3. Technical support is available, the last time we had a cookie retention problem, the engineer gave us a solution in 10 minutes.

They recently came out with a newIntelligent Routing FunctionQuite interesting to automatically match the fastest routes. It's like installing GPS for data collection, which road is not blocked. If you need it, you can take a look at the official website, and new users get 5GB of experience traffic (don't ask me for a coupon code, I really don't have one).

Lastly, I would like to say that proxy IP is not a panacea, and it should be used in conjunction with anti-climbing strategies to maximize its effectiveness. Just like frying vegetables with a good pot is not enough, the fire seasoning have to keep up. What specific questions welcome to leave a message, see will be back.
