Proxy IP Crawler: Highly efficient proxy IP integrated web crawler tool recommendation

How to choose a proxy IP crawler tool? This is enough to read

Brothers engaged in data capture understand that no reliable proxy IP is like driving without a steering wheel. There are a variety of tools on the market, today we will break up the crumbs to say, how to pick the best proxy IP capture tool, and incidentally, we are honed three years of theipipgoServices.

How many of the three pits of tool selection have you stepped in?

1. IP quality not up to scratch: Many free tools claim to have millions of IP pools, but the actual rate is less than 10%.
2. Slower than a snail.: some tools don't even support basic multithreading
3. Configuration complexity discouragement: Newbies can't read the docs for half an hour and still not be able to run it

Last year to help a friend tuned a certain open source tool, just processing the CAPTCHA took two days. Later, I switched toipipgoThe SDK, which directly integrates the automatic IP rotation function, directly doubles the efficiency.

Practical recommendation: three pro-tested good tools

Hands on configuration of ipipgo proxy

Here's a chestnut in Python. Remember to install the ipipgo SDK package first:

import ipipgo

 Initialize the client (remember to replace your own API key)
client = ipipgo.Client(api_key="your_key_here")

 Get the latest proxy IP
proxy = client.get_proxy()

 Use in requests
response = requests.get(
    'https://target-site.com',
    proxies={
        'http': f'http://{proxy.ip}:{proxy.port}',
        'https': f'http://{proxy.ip}:{proxy.port}'
    }
)

Here's the kicker.Automatic switching mechanism: It is recommended to set the IP to change every 50 requests, or to switch immediately when encountering a 403 error. ipipgo's package comes with smart switching, which is a lot less work than writing your own rotation logic.

Frequently Asked Questions QA

Q: What should I do if my proxy IP is always blocked?
A: three methods: 1. reduce the frequency of requests 2. use ipipgo's on-demand billing package 3. with the User-Agent random switching

Q: What if I need to deal with CAPTCHA?
A: It is recommended to use the image recognition service, or switch to ipipgo's high stash of residential IP, which has been tested to reduce the CAPTCHA trigger rate of 70%.

Q: Will it conflict to have more than one crawler on at the same time?
A: Remember to assign independent API keys to each crawler instance, and the ipipgo backend can monitor the use of each key individually

Why do you recommend ipipgo?

A little more must be said about self-service:
1. ExclusiveIP Quality Scoring SystemAutomated filtering of failed nodes
2. Support for hourly billing, small projects do not need to buy a whole month package
3. 7 × 24 technical customer service, the last three o'clock in the morning to mention the work order actually seconds back!
4. Provision of completeRequest Log AnalysisIt's very easy to locate the problem.

One final piece of cold knowledge: many of my peers don't know that ipipgo'sCity-level targeted acquisitionFunction, do localized data collection is very good to use. For example, as long as the Shanghai region's proxy IP, background check on the line, do not have to write their own screening logic.
