Ruby proxy IP network crawling: Ruby proxy network crawler practice

Ruby crawler meets IP blocked? Try this trick to save your life

Crawlers know that the biggest headache is that the target site suddenly gives you aIP blocking. Last week I have a friend with Ruby to climb the e-commerce data, just run half an hour on the 403 error, so angry that he almost smashed the keyboard. Later I taught him to use proxy IP rotation, and now run for three consecutive days without problems.

Hands-On Cloak for Ruby Crawlers

Ruby comes with the Net::HTTP library actually comes with proxy support, change three lines of code can realize IP switching. See this live example:

require 'net/http'

proxy_addr = 'gateway.ipipgo.com' Here is the address of the proxy server.
proxy_port = 9021 port number
proxy_user = 'Your account' Whitelisting is highly recommended.
proxy_pass = 'Your key'

uri = URI('https://target-site.com')
Net::HTTP.start(uri.host, uri.port,
  proxy_addr, proxy_port, proxy_user, proxy_pass) do |http|
  response = http.get(uri.request_uri)
  puts response.body
end

Notice the use ofSocks5 proxy for ipipgoIt is more stable than HTTP proxy. If you encounter certificate problems, remember to addverify_mode: OpenSSL::SSL::VERIFY_NONE(Test environment recommendations only).

Look for these three things when choosing a proxy IP

Special reminder: don't be greedy and cheap with a free agent, before we tested the free agent'sResponse times are on average 8 times slower, and there is a 30% probability that the real IP will be leaked.

A practical guide to avoiding the pit

While helping a client with airfare monitoring recently, I found a few key tips:
1. Randomly select the export IP of a different country for each request (ipipgo supports 200+ countries)
2. Do not set the timeout time more than 15 seconds, otherwise it is easy to be recognized by the anti-climbing system.
3. UseUser-Agent.randomizeLibrary automatically switches browser fingerprints
4. Important! Before crawling withping to detect proxy connectivity

Frequently Asked Questions

Q: What should I do if my Ruby crawler is always stuck on SSL validation?
A: Add this paragraph to the code:
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
But never use it in a production environment!

Q: Which one should I choose, dynamic IP or static IP?
A: Depends on the usage scenario. NeedLong-term maintenance sessions(e.g., automated order placement) with a static IP, it is more cost-effective to use a dynamic IP for simple data collection.

Q: Are ipipgo's packages expensive?
A: A chestnut: Dynamic Residential Enterprise Edition 9.47 yuan / GB, according to our measured data, climb 100,000 web pages consume about 3GB of traffic, the cost is less than 30 dollars, cheaper than self-built agent pool at least 60%.

Why do you recommend ipipgo?

Real experience after using it for more than 6 months:
✔️ At 3am customer service actually returned the work order in seconds.
✔️ Supportpay per volumeNo need to prepay the balance
✔️ provides a library of ready-to-use Ruby code samples.
✔️ Exclusive TK line is particularly effective for certain platforms

They have recently launched their new onlineTraffic Alert FunctionThe company has a lot of experience in the field of agent services, and it has set a threshold for automatic SMS reminders, so you will never have to worry about exceeding the quota again. If you ask me, choosing an agent is just like looking for a partner, it's useless to just look at the price, it's only hard to be able to carry things at the critical moment.
