Why use a proxy ip to catch LinkedIn?

Old iron engaged in data collection know that LinkedIn's protection mechanism is even stricter than the security door. For example, if you use your own broadband to brush for half an hour, you are guaranteed to receive a "your requests are too frequent" warning. At this timeProxy ip service for ipipgoIt's like a master key that helps youBypassing Access Restrictions. Note that it's not ha, it's purely to make the server think that a different user is operating on each request.

There is a competitive analysis of buddies told me that his company used a free proxy, the result of the data did not pick but hit the Trojan horse. This thing sounds evil, but with a regular proxy service provider such as ipipgo, you can make sure that you can get the data from the Trojan.IP pool is clean and hygienicUnlike some wildcard proxies, the IPs are loaded with viruses.

Second, hand in hand to teach you to match the proxy ip, white people can immediately get started!

First of all, I understand the principle: each request is a different IP address, so that LinkedIn's servers do not recognize the same user. Let's use python's requests library as an example:

import requests
from itertools import cycle

 List of proxies provided by ipipgo
proxies = [
    "http://user:pass@123.123.123.123:8888",
    "http://user:pass@124.124.124.124:8888"
]
proxy_pool = cycle(proxies)

for page in range(1,10): current_proxy = next(proxy_pool)
    current_proxy = next(proxy_pool)
    current_proxy = next(proxy_pool)
        response = requests.get(
            "https://www.linkedin.com/company/目标企业/posts/",
            proxies={"http": current_proxy},
            timeout=10
        )
        print(f "Page {page} captured successfully")
    except.
        print("Current IP failed, automatically switch to the next one")

There are a couple potholes to watch out for here:Don't set the timeout for more than 15 seconds, otherwise it is easy to be targeted by anti-crawling mechanisms;User Agent HeaderTo randomize the replacement, ipipgo has a ready-made UA library in the backend that can be called directly.

Third, the actual pit guide, these minefields must not step on

Based on three months of data from our testing team, we've put together a pit avoidance form:

There is a cross-border e-commerce customers, before the collection of 200 times per hour was blocked, change to use theipipgo's intelligent scheduling systemAfter that, the requests were spread out to different IP segments, and now the average daily collection is 5,000 times steady as an old dog.

Fourth, the common problems QA, you step on the pit of others have traveled

Q: What should I do if my IP is blocked halfway through the collection?
A: Open in the ipipgo consoleautomatic fusing mechanismWhen an IP anomaly is detected, it is automatically quarantined and a new IP is added to the connection pool.

Q: What if I need to capture content from multiple countries?
A: Go with ipipgo'sglobal positioning IPservice, you can specify the export nodes in the United States, Europe and other regions, and collect localized content more accurately.

Q: How to do the enterprise dynamic update reminder?
A: with ipipgo'sLong-lasting static IPservice, set up timed tasks + incremental collection, more stable than using dynamic IP.

Fifth, upgrade the gameplay, so that the collection efficiency doubled

The combinations that the masters are using:
1. With ipipgoResidential Proxy IPSimulate real user behavior
2. SettingsRandom Click Interval(3-8 seconds floating)
3. OpeningDeep scroll loadingFeature to automatically load the content of the comments section
4. DockingAutomatic CAPTCHA RecognitionModule (to be configured separately)

There is a team doing public opinion monitoring, originally can only pick 300 pieces of data per day, after using this program directly dry to 5000 pieces. They said the most flavorful is ipipgo'sProprietary Channel TechnologyIt also guarantees stable bandwidth during peak hours, unlike some proxies that get stuck in PPT at night.
