CloudScraper Go

Simple go module to bypass CloudFlare securities

For now only passive checks based on TLS footprint (JA3) and user agents are handled
Inspired of python project https://github.com/venomous/cloudscraper

Rely on CycleTls to customize JA3

JA3 list: https://raw.githubusercontent.com/trisulnsm/trisul-scripts/master/lua/frontend_scripts/reassembly/ja3/prints/ja3fingerprint.json

Get my JA3: https://kawayiyi.com/tls

Example of usage

Simple Post

package main

import (
    "github.com/RomainMichau/cloudscraper_go/cloudscraper"
)

func main() {

    client, _ := cloudscraper.Init(false, false)
    res, _ := client.Post("https://www.facebook.com/anything/", make(map[string]string), "")
    res2, _ := client.Get("https://www.facebook.com/anything/", make(map[string]string), "")
    print(res.Body)
    print(res2.Body)
}

Customize request

package main

import (
    "github.com/Danny-Dasilva/CycleTLS/cycletls"
    "github.com/RomainMichau/cloudscraper_go/cloudscraper"
)

func main() {

    client, _ := cloudscraper.Init(false, false)
    options := cycletls.Options{
        Headers:         map[string]string{"my_custom_header": "header_value"},
        Body:            "",
        Proxy:           "proxy.company.com",
        Timeout:         10,
        DisableRedirect: true,
    }
    res, _ := client.Do("https://www.facebook.com/anything", options, "PUT")
    print(res.Body)
}

Async Request

package main

import (
    "github.com/Danny-Dasilva/CycleTLS/cycletls"
    "github.com/RomainMichau/cloudscraper_go/cloudscraper"
)

func main() {

    client, _ := cloudscraper.Init(false, true)
    options := cycletls.Options{
        Headers:         map[string]string{"my_custom_header": "header_value"},
        Body:            "",
        Timeout:         10,
        DisableRedirect: true,
    }
    client.Queue("https://www.facebook.com/anything", options, "PUT")
    respChannel := client.RespChan()
    res := <-respChannel
    print(res.Body)
}
