Command line acquisition tool: wget parameter optimization and camouflage scheme

The secret weapon that turns wget into a data harvester

We are engaged in data collection brothers are clear, with wget under the things like driving a tractor to collect wheat - simple and rough, but the movement is big. If you don't do a good job of camouflage, you will be exterminated by the target site as a pest in a minute. Today, we will teach you how to install the tractor with thecloaking device, making it a silent reaper.

Proxy IP is the real armor

Ever seen a fool fight in a tank top? That's what the Naked Crawler is like. Putting a proxy IP on a wget is like putting body armor on a soldier. This is a must for my brother.ipipgoThe best thing about it: his proxy pool has more IPs than a square-dancing mom, and he can change to a new vest at any time. Use this configuration command:

wget --proxy=on --proxy-user=ipipgo_user --proxy-password=your_pwd
--proxy=http://gateway.ipipgo.com:9021 https://目标网站

Take care to replace _password_ with your own account key, so that each request is like a new ID card, and the site simply can't figure out the routine.

Three knives for parameter tuning

Here's the kicker.-user-agentThis teaser parameter. It's recommended to have 5-10 UA's of different browsers on hand to rotate through, so you don't always have Chrome on your back. With ipipgo's Dynamic Residential Proxy, it's alive and well with a global internet user accessing it.

The hidden tricks of the master of disguise

1. time trick: Slip a sleep command into the script, and don't make the access time too regular, like a human who swipes his cell phone in the middle of the night.
2. batch harvest: Split the task into dozens of small files, and download them in batches using different export IPs from ipipgo.
3. stagger travel to the peak: Observe low traffic periods on target websites and set wget to start automatically at 2-5am

Practical QA First Aid Kit

Q: What should I do if I keep getting banned from IP?
A: 80% of the proxy quality pulls crotch. Change ipipgo'sLong-lasting static residential agentHis IP survival cycle is 3 times more than that of his peers, and he personally tested that he did not turn over for half a month of continuous picking.

Q: What should I do if I get disconnected in the middle of the download?
A: Sacrifice-cParameters then, with ipipgo's disconnection automatic IP change function, even if the telecom bombing can be renewed transmission.

Q: How can I tell if the disguise is successful?
A: Use this command to look at the request headers received by the site:

wget -S --spider --proxy=... Target URL

Focus on checking the X-Forwarded-For fields, if it shows ipipgo's proxy IP instead of your local IP, it's a good idea to disguise it.

The Ultimate Combo

Finally, a crushed configuration template:

wget -c -np -r -l 5
--limit-rate=150k
--random-wait=45
--user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36..."
--header="Accept-Encoding: gzip"
--proxy-user=ipipgo_dynamic_key
--proxy-password=Auto-refresh token
--proxy=http://rotating.ipipgo.com:9083

This combo is paired with ipipgo'sIntelligent RoutingThe feature automatically selects the fastest node. Remember to regularly update the UA and download intervals, the site wind control see have to shout big brother.
