Usage

Docker

docker run uranusq/gogetcrawl url *.tutorialspoint.com/* --ext pdf --limit 5

Docker compose

docker-compose up --build

CLI usage

• See commands and flags:

gogetcrawl -h

Get URLs

• You can get multiple-domain archive data, flags will be applied to each. By default, you will get all results displayed in your terminal (use --collapse to get unique results):

gogetcrawl url *.example.com *.tutorialspoint.com/* --collapse

• To limit the number of results, enable output to a file and select only Wayback as a source you can:

gogetcrawl url *.tutorialspoint.com/* --limit 10 --sources wb -o ./urls.txt

• Set date range:

gogetcrawl url *.tutorialspoint.com/* --limit 10 --from 20140131 --to 20231231

Download files

• Download 5 PDF files to ./test directory with 3 workers:

gogetcrawl download *.cia.gov/* --limit 5 -w 3 -d ./test -f "mimetype:application/pdf"

Package usage

go get github.com/karust/gogetcrawl

For both Wayback and Common crawl you can use concurrent and non-concurrent ways to interract with archives:

Wayback

• Get urls

package main

import (
	"fmt"

	"github.com/karust/gogetcrawl/common"
	"github.com/karust/gogetcrawl/wayback"
)

func main() {
	// Get only 10 status:200 pages
	config := common.RequestConfig{
		URL:     "*.example.com/*",
		Filters: []string{"statuscode:200"},
		Limit:   10,
	}

	// Set request timout and retries
	wb, _ := wayback.New(15, 2)

	// Use config to obtain all CDX server responses
	results, _ := wb.GetPages(config)

	for _, r := range results {
		fmt.Println(r.Urlkey, r.Original, r.MimeType)
	}
}

• Get files:

// Get all status:200 HTML files 
config := common.RequestConfig{
	URL:     "*.tutorialspoint.com/*",
	Filters: []string{"statuscode:200", "mimetype:text/html"},
}

wb, _ := wayback.New(15, 2)
results, _ := wb.GetPages(config)

// Get first file from CDX response
file, err := wb.GetFile(results[0])

fmt.Println(string(file))

CommonCrawl

To use CommonCrawl you just need to replace wayback module with commoncrawl. Let's use Common Crawl concurretly

• Get urls

cc, _ := commoncrawl.New(30, 3)

config1 := common.RequestConfig{
	URL:        "*.tutorialspoint.com/*",
	Filters:    []string{"statuscode:200", "mimetype:text/html"},
	Limit:      6,
}

config2 := common.RequestConfig{
	URL:        "example.com/*",
	Filters:    []string{"statuscode:200", "mimetype:text/html"},
	Limit:      6,
}

resultsChan := make(chan []*common.CdxResponse)
errorsChan := make(chan error)

go func() {
	cc.FetchPages(config1, resultsChan, errorsChan)
}()

go func() {
	cc.FetchPages(config2, resultsChan, errorsChan)
}()

for {
	select {
	case err := <-errorsChan:
		fmt.Printf("FetchPages goroutine failed: %v", err)
	case res, ok := <-resultsChan:
		if ok {
			fmt.Println(res)
		}
	}
}

• Get files:

config := common.RequestConfig{
	URL:     "kamaloff.ru/*",
	Filters: []string{"statuscode:200", "mimetype:text/html"},
}

cc, _ := commoncrawl.New(15, 2)
results, _ := wb.GetPages(config)
file, err := cc.GetFile(results[0])
