What do you fear most about data crawling? Especially when batch processing, if you are not careful, you will be caught by the website wind control. Today we nag how to use proxy IP compliance grip robots.txt, both can get the data and do not step on the mine.
First of all, understand robots.txt is what the hell!
This file is like a traffic sign for a website, telling you which intersections you can go (allowing crawling) and which are one-way streets (prohibiting access). For example, if you seeDisallow: /adminThe smart ones know to take a detour. But some newbies go straight through, and end up eating closed doors in minutes.
User-agent.
Allow: /public
Disallow: /private
Why Proxy IPs are a must-have
Imagine you are going through customs with ten boxes of goods, and if you use the same passport for all of them... (the image is too beautiful to look at). Using a proxy IP is like having multiple passports:
| take | Naked IP | proxy IP |
|---|---|---|
| single request | It barely works. | lit. kill a chicken with a sledgehammer |
| batch file collection | Died on the spot. | Silky smooth |
Here's the point! You have to look at three things to choose an agent:The IP pool is large enough,Switching is fast enough,Hidden enough.It is not a good idea to use the same kind of technology as you do in your own home. Here must be Amway's own products ipipgo, 100,000 dynamic IP pool, comes with request header camouflage, who uses who knows.
Four Steps to Compliance Acquisition
1. peaceful measures before using force (idiom); diplomacy before violence: Read robots.txt first, don't be blind.
2. Distributed fire: Use ipipgo's rotating proxies, don't catch a single IP and build it!
3. control the tempo: Don't request less than 2 seconds between requests, and don't crawl too often!
4. Keep the evidence.: Records the timestamp of each request and the proxy IP used
import requests
from ipipgo import ProxyPool
proxies = ProxyPool.get_ips(type='https', count=5) get 5 IPs from ipipgo
for url in target_list.
proxy = next(proxies)
try.
res = requests.get(url, proxies={"https": proxy}, timeout=10)
print(f "Successfully fetched data using {proxy}")
time.sleep(3)
except.
print(f"{proxy} dropped, automatically switching to the next one")
Guide to avoiding the pit
- seeCrawl-delay: 10Don't be a smart ass and wait 10 seconds.
- don't touch the tape!Disallowdirectory, some sites will put bait files to fish for
- Don't fight the CAPTCHA, change your IP when it's time to change ipipgo's quality proxies!
Frequently Asked Questions QA
Q: Can a website be crawled without robots.txt?
A: What do you think! You have to look at the other side of the terms of service, some hidden in the user agreement of the pit more hidden
Q: Is it okay to use a free proxy?
A: Free is the most expensive! I've met a guy who used a free proxy and all he caught was ad code...still ipipgo's exclusive IP is reliable!
Q: What should I do if all the proxy IPs suddenly hang up?
A: First check the request frequency, if there is no problem hurry to contact ipipgo customer service, they have a large IP pool, within five minutes can change the batch of new
Say something from the heart.
Doing data collection is like dancing tango, you have to follow the rhythm of the website. Don't always think of violent crack, use ipipgo this kind of professional tools, both the rules and can work efficiently. Remember, live a long time crawler are not rash!
