Fast golang web crawler for gathering URLs and JavaScript file locations. This is basically a simple implementation of the awesome Gocolly library.
Single URL:
echo https://google.com | hakrawler
Multiple URLs:
cat urls.txt | hakrawler
Timeout for each line of stdin after 5 seconds:
cat urls.txt | hakrawler -timeout 5
Send all requests through a proxy:
cat urls.txt | hakrawler -proxy http://localhost:8080
Include subdomains:
echo https://google.com | hakrawler -subs
Note: a common issue is that the tool returns no URLs. This usually happens when a domain is specified (https://example.com), but it redirects to a subdomain (https://www.example.com). The subdomain is not included in the scope, so the no URLs are printed. In order to overcome this, either specify the final URL in the redirect chain or use the
-subsoption to include subdomains.
Get all subdomains of google, find the ones that respond to http(s), crawl them all.
echo google.com | haktrails subdomains | httpx | hakrawler
First, you'll need to install go.
Then run this command to download + compile hakrawler:
go install github.com/hakluke/hakrawler@latest
You can now run ~/go/bin/hakrawler. If you'd like to just run hakrawler without the full path, you'll need to export PATH="~/go/bin/:$PATH". You can also add this line to your ~/.bashrc file if you'd like this to persist.
echo https://www.google.com | docker run --rm -i hakluke/hakrawler:v2 -subs
It's much easier to use the dockerhub method above, but if you'd prefer to run it locally:
git clone https://github.com/hakluke/hakrawler
cd hakrawler
sudo docker build -t hakluke/hakrawler .
sudo docker run --rm -i hakluke/hakrawler --help
Note: This will install an older version of hakrawler without all the features, and it may be buggy. I recommend using one of the other methods.
sudo apt install hakrawlerThen, to run hakrawler:
echo https://www.google.com | docker run --rm -i hakluke/hakrawler -subs
