Rust Crawler Framework: High Performance Concurrent Collection Library

Hands-On Proxy Capture with Rust

Recently, a lot of data collection partners and I spit, said that now the site anti-climbing more and more strict. This is not, last week a brother with Python to write the collection script just run two days on the blocked IP. this time to take out my home magic ---Rust + Proxy IPThe combo is up.

Let's talk about why we chose Rust, the concurrency performance of this dude is really top, faster than Python is not a half a star. For example, to handle 100,000 requests, Python may take two cups of coffee time, Rust two minutes to give you a clear understanding.

Proxy IPs are the real deal.

It's not enough to be fast, you have to learncamouflageThe first thing you need to do is to use the ipipgo proxy service. Here we have to invite our ipipgo proxy service. The quality of their residential proxy IP can really beat, I have tested the continuous collection of 8 hours have not been blocked. Here to teach you a trick: the proxy IP pool and Rust's asynchronous characteristics of the combination of use, the effect of direct pull full.

// Example of configuring a proxy
use reqwest::Proxy;

let proxy = Proxy::all("http://user:pass@ipipgo-proxy:8080")? ;
let client = reqwest::Client::builder()
    .proxy(proxy)
    .build()? ;

Practical Tips and Tricks

Here are a few dry tips summarized from real projects:

1. Remember to give each concurrent taskRandom nap.Don't let the site think you're a robot
2. Don't panic when you encounter CAPTCHA, use ipipgo's dynamic IP switching function, it works!
3. Don't be too cheap to set a timeout, 10-30 seconds is recommended to be more secure

question-and-answer session

Q: What should I do if my proxy IP often fails?
A: This is why recommended ipipgo, their IP pool updated every day 200,000 +, the failure of the automatic replacement of new

Q: What is the appropriate number of concurrency?
A：Ordinary website open 50-100 threads enough, with ipipgo IP resources completely hold

Q: What should I do if I encounter SSL authentication failure?
A: In the client configuration, adddanger_accept_invalid_certs(true)But don't use it indiscriminately.

Say something from the heart.

To engage in this line of data collection, tools are important but resources are more important. I've used a lot of proxy service providers before, and finally used ipipgo for a long time to get a better idea of how to collect data.be spared worryThe first time I saw the company, I was able to get a good deal of money from the company. Their customer service is really 7 × 24 online, once at three o'clock in the middle of the night encountered problems actually seconds back, this service is no one.

One final note to newbies: don't just focus on code optimization.A good proxy IP is the root of successful harvesting. Get the ipipgo API into your Rust project and you'll come back and thank me (laughs).
