Rotation of data center proxies: automatic switching of anti-blocking IPs

What does a rotating data center agent really do?

Let's start with a real one - why do we need to rotate agents? To give a chestnut, just like playing the game to open a small number, a number was blocked immediately change another continue to play. A lot of friends doing data collection have encountered the bad thing of IP blocked, especially for e-commerce price comparison, content aggregation and these need a lot of access to the scene. At this timeAutomatic switching of rotating agentsIt's just a lifesaver. ipipgo's proxy pool can automatically give you a new IP, saving you 800 times more work than cutting it manually.

How to play around with auto switching? Hands-on guide to match the configuration

Here's the whole Python example for the guys (don't be afraid of the code, just copy it):

import requests
from itertools import cycle

 List of proxies from the ipipgo backend (remember to replace them with your own)
proxies = [
    "http://user:[Password]@gw1.ipipgo.com:9020",
    "http://user:[Password]@gw2.ipipgo.com:9020",
     ... Continue to add more proxies
]
proxy_pool = cycle(proxies)

for _ in range(10):
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        response = requests.get("https://目标网站",
                             proxies={"http": current_proxy}, timeout=10)
                             timeout=10)
        print("Using proxy this time:", current_proxy, "Status code:", response.status_code)
    except: "current_proxy", "status_code:", response.status_code)
        print("This proxy is kneeling, switch to the next one right away!" , current_proxy)

Here's the point:The timeout parameter must be setDon't let crappy proxies jam the program; a loop call to next() enables automatic switching. ipipgo's proxies are load-balanced, and there are actually hundreds of IPs queuing up behind an address.

Three hard truths about picking ipipgo

There are so many agents on the market, why do you favor this one? Let's make a real comparison:

A special shout-out goes to theirIntelligent Routing SystemThe IP segment that can automatically avoid being blacked out by the target website. Last time there is a do airfare comparison of customers, with other agents every day was sealed, changed to ipipgo directly after the stability of the run for three days.

Frequently Asked Questions for Beginners

Q: Can you rotate too often and get benched instead?
A: This is ipipgo's masterpiece, their switching algorithm will be dynamically adjusted according to the strength of the target site's wind control, neither stupidly fast nor too slow, this month there is a product review collection of customers, with the ordinary agent every day was blocked 20 times, after the change ipipgo down to 2 times a day.

Q: Do I need to maintain my own IP pool?
A: No need at all! Their background will automatically eliminate the invalid IP, but also according to your use of the scene to recommend the appropriate geographical distribution. There is a do local life services buddy, specifically to the Yangtze River Delta region IP pool, collection efficiency directly doubled.

Q: Can you carry sudden traffic?
A: This is the advantage of the data center agent, ipipgo's server room reserves millions of IP resources. Last month, during the double eleven, a customer doing e-commerce monitoring suddenly want to increase the amount of 5 minutes to give him the expansion of 5000 IP, spread out with no problem.

A Guide to Avoiding the Pit (Blood and Tears)

Seen too many people fall into these pits:

1. Don't try to buy a shared agent cheap, the kind of dozens of dollars a month, ten IP nine thousand people are using, not seal you seal who?
2. Pay attention to the service provider'sIP Survival ReportThe ipipgo backend can see the length of time each IP has been alive in real time.
3. Test period must try high concurrency scenarios, some agents run well in single-threaded, a multi-threaded on the crotch pull!

Finally, a cold piece of knowledge: many sites are not actually blocking IPs, but blockingIP segmentipipgo's proxies are spread across 300+ different network segments, which is the key to blocking, and is much more realistic than just piling up the number of IPs.
