Web Crawling Proxy: Highly anonymous proxy IP for intelligent web crawling

Why is web crawling always blocked? You may be missing this magic tool

Engaged in data crawling old drivers understand that the biggest headache is just grabbed a few pages on the IP blocked. those sites anti-crawler mechanism than the cell gates are even more stringent, moving to give you an "access anomaly" warning. At this time, if the hard head with their own IP hard just, minutes will be hit into the blacklist.

Take a real case: there is a price comparison website team, using their own server to capture data, the results of the next day the entire company network are blocked by the target platform. Later, they switched toHighly anonymized proxy IPs for ipipgo, by rotating the IP addresses of different regions, it is now steadily crawling millions of data per day and has never rolled over again.

Normal proxies vs. high anonymity proxies, the difference is bigger than you think

A lot of newbies think that just find a free agent can be used, the results found that either slow speed into a turtle, or just used to be recognized. Here must be popularized under the agent of the three stealth level:

What makes ipipgo's highly anonymous proxy so reliable is that it disguises your request exactly as a normal user would access it. Just as a secret agent would change clothes and disguise himself when performing a mission, our request will automatically remove all proxy features, so that even the strictest anti-crawling system will not be able to see the cracks.

Hands-on guide to configure proxy crawling

Here's a chestnut in Python, suppose we want to crawl an e-commerce site with the requests library:

import requests

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

response = requests.get('https://目标网站.com', proxies=proxies, timeout=10)
print(response.text)

Note that you have to replace username and password with the authentication information you get in the ipipgo backend. It is recommended that you randomly switch IPs for each request. This can be done by setting up an automatic rotation policy directly in the ipipgo control panel.

Top 3 Tips to Prevent Banning

1. The speed should be like a real person.Don't send requests as if you're playing chicken blood, add random delays as appropriate, ipipgo's intelligent scheduling system can automatically adjust the frequency of requests.

2. The disguise has to be complete.Remember to randomly change the User-Agent, this works better with ipipgo's geolocation camouflage!

3. Fail with grace.: Don't be dead set on a 403 error, switch IPs and retry immediately. ipipgo's API can fetch the list of available proxies in real time.

QA time: the pitfalls you may have encountered

Q: Why do I still get blocked after using a proxy?
A: Check if you are using a transparent proxy, or the request header has a proxy feature. If you use ipipgo, remember to turn on "deep anonymization" mode.

Q: How many IPs are needed at the same time to be enough?
A: Depends on the size of the crawl, generally small projects with ipipgo 500 IP package is enough, the amount of large data is recommended to choose 5000 IP of the enterprise version!

Q: What should I do if my overseas website is particularly slow to crawl?
A: In the ipipgo background to select the target area nodes, such as catching the United States site on the local IP room, the speed can be increased by 3-5 times!

When it comes to choosing the right proxy service provider, you can really save half of your mind. ipipgo has a particularly practical "trial package", newcomers can test the effect by spending a milk tea money. Their IP survival rate can reach 95% or more, which is much better than those who are using the chicken proxy that will lose connection. Recently, there is also a "smart route" black technology, automatically select the fastest line, the actual test capture efficiency directly doubled.

If you encounter any moth in the configuration process, do not hesitate to directly find their technical support. Last time I had a proxy authentication problem, customer service at two o'clock in the morning also returned the message in seconds, this service is really enough to fight. Remember, professional things to professional tools, don't go against your own hair ~!
