Proxy pool (proxypool): self-built IP proxy pool building and maintenance tutorials

Hands on with building a reliable agent pool

What is the biggest headache for friends who engage in data capture? Nine out of ten will complain to you that the IP is blocked. At this time there is a proxy pool of their own is like having a master key, Lao Zhang I was doing crawler project, three days two to three times was blocked IP, and then tossed their own proxy pool to find the way.

Why do I have to build my own agent pool?

The free agents on the market look pretty, but those who have actually used them know that:Nine out of ten agents are in trouble.. Either you can't connect, or the speed is as slow as a snail. The best thing about building your own pool is that you can control the quality, change the water regularly like a fish, and make sure that the pool is full of "good fish" that are alive and kicking.

Choosing a proxy IP is like buying groceries

You have to look at three things to pick a proxy IP:
1. Positive sources of goods (operator resources)
2. Variety should be complete (dynamic and static)
3. Long shelf life (survival time)
Here must be complimented ipipgo home goods, their home directly from the local operator to take resources, unlike some second-hand dealers pouring IP. especially the TK line, cross-border e-commerce friends used to say stable.

Four Steps to Build

 Using Python as an example, use the ipipgo API to get a proxy
import requests

def get_proxies():
    api_url = "https://api.ipipgo.com/get?format=json"
    res = requests.get(api_url).json()
    return res['proxies']

The first step is to get a proxy collector, it is recommended to use Redis survivor, access speed. The second step is to get a validation module, don't think it's too much trouble, if you save this step, you'll be blind. The third step to get the scheduling system, do not let some IP tired to death, some idle panic. Finally, the whole API interface, convenient for other programs to call.

There is a way to care for it.

Maintaining an agency pool is similar to keeping a car, it has to be serviced regularly:
- Automatically clean up invalid IPs at dawn every day
- Dynamic resizing of pools based on business volume
- Manual replenishment in case of unforeseen circumstances
One advantage of using ipipgo's client is that you can see the IP health in real time, like a car dashboard, so you can find out what's wrong right away.

Frequently Asked Questions QA

Q: What about total agent failure?
A: It is recommended to change the static residential IP, although more expensive but durable. ipipgo's static package of 35 bucks / IP can be used for a month, do long-term projects cost-effective.

Q: How can I test the quality of the agent?
A: Don't just measure connectivity! To simulate real requests, such as access to the target site to measure the return status code, the response time should not exceed 3 seconds.

Money-saving tips

The combination of dynamic and static is the king! Dynamic IP as the main force, static IP to deal with critical tasks. ipipgo's dynamic package minimum 7 yuan more than 1G traffic, the ordinary collection enough to use. If the enterprise-level projects, directly on the customized program, can save two or three percent of the expenditure.

When it comes to proxy pooling this thing is a continuous optimization process. At first, you may find it troublesome, but when you run smoothly, you will find it really fragrant. If you are too lazy to toss, directly with ipipgo ready-made program can also be, their API docking is particularly troublesome, the document is also written to understand, suitable for newcomers to start.
