Humanoid
A Node.js package to bypass WAF anti-bot JS challenges.
About
Humanoid is a Node.js package to solve and bypass CloudFlare (and hopefully in the future - other WAFs' as well) JavaScript anti-bot challenges.
While anti-bot pages are solvable via headless browsers, they are pretty heavy and are usually considered over the top for scraping.
Humanoid can solve these challenges using the Node.js runtime and present the protected HTML page.
The session cookies can also be delegated to other bots to continue scraping causing them to avoid the JS challenges altogether.
Features
- Random browser User-Agent
- Auto-retry on failed challenges
- Highly configurable - hack custom cookies, headers, etc
- Clearing cookies and rotating User-Agent is supported
- Supports decompression of
Brotlicontent-encoding. Not supported by Node.js'requestby default!
Installation
via npm:
npm install --save humanoid-js
Usage
Basic usage with promises:
const Humanoid = require("humanoid-js");
let humanoid = new Humanoid();
humanoid.get("https://www.cloudflare-protected.com")
.then(res => {
console.log(res.body) // <!DOCTYPE html><html lang="en">...
})
.catch(err => {
console.error(err)
})
Humanoid uses auto-bypass by default. You can override it on instance creation:
let humanoid = new Humanoid(autoBypass=false)
humanoid.get("https://canyoupwn.me")
.then(res => {
console.log(res.statusCode) // 503
console.log(res.isSessionChallenged) // true
humanoid.bypassJSChallenge(res)
.then(challengeResponse => {
// Note that challengeResponse.isChallengeSolved won't be set to true when doing manual bypassing.
console.log(challengeResponse.body) // <!DOCTYPE html><html lang="en">...
})
}
)
.catch(err => {
console.error(err)
})
async/await is also supported, and is the preferred way to go:
(async function() {
let humanoid = new Humanoid();
let response = await humanoid.sendRequest("www.cloudflare-protected.com")
console.log(response.body) // <!DOCTYPE html><html lang="en">...
}())
Humanoid API Methods
rotateUA() // Replace the currently set user agent with a different one
clearCookies() // "Set a new, empty cookie jar for the humanoid instance"
get(url, queryString=undefined, headers=undefined) // Send a GET request to `url`.
// if passed, queryString and headers should be objects
post(url, postBody=undefined, headers=undefined, dataType=undefined) // Send a POST request to `url`.
// `dataType` should be either "form" or "json" - based on the content type of the POST request.
sendRequest(url, method=undefined, data=undefined, headers=undefined, dataType=undefined)
// Send a request of method `method` to `url`
bypassJSChallenge(response) // Bypass the anti-bot JS challenge found in response.body
TODOs
- [ ] Add command line support
- Support a flag to return the cookie jar after challenge solved - for better integration with other tools and scrapers
- Have an option to simply bypass and return the protected HTML
- [ ] Solve other WAFs similar anti-bot challenges
- [ ] Add tests for request sending and challenge solving
- [ ] Add Docker support 🐳
Issues and Contributions
All anti-bot challenges are likely to change in the future. If this is the case, please open an issue explaining
the problem - try to include the target page if possible. I'll do my best to keep the code up to date with
new challenges.
Any and all contributions are welcome - and are highly appreciated.
