curl

Transfers data from or to a server. Supports most protocols, including HTTP, HTTPS, FTP, SCP, etc. More information: https://curl.se/docs/manpage.html.

• Make an HTTP GET request and dump the contents in stdout:

curl https://example.com

• Make an HTTP GET request, fo[L]low any 3xx redirects, and [D]ump the reply headers and contents to stdout:

curl --location --dump-header - https://example.com

• Download a file, saving the [O]utput under the filename indicated by the URL:

curl --remote-name https://example.com/filename.zip

• Send form-encoded [d]ata (POST request of type application/x-www-form-urlencoded). Use --data @file_name or --data @'-' to read from stdin:

curl -X POST --data 'name=bob' http://example.com/form

• Send a request with an extra header, using a custom HTTP method and over a pro[x]y (such as BurpSuite), ignoring insecure self-signed certificates:

curl -k --proxy http://127.0.0.1:8080 --header 'Authorization: Bearer token' --request GET|PUT|POST|DELETE|PATCH|… https://example.com

• Send data in JSON format, specifying the appropriate Content-Type [H]eader:

curl --data '{"name":"bob"}' --header 'Content-Type: application/json' http://example.com/users/1234

• Pass client certificate and key for a resource, skipping certificate validation:

curl --cert client.pem --key key.pem --insecure https://example.com

• Resolve a hostname to a custom IP address, with [v]erbose output (similar to editing the /etc/hosts file for custom DNS resolution):

curl --verbose --resolve example.com:80:127.0.0.1 http://example.com
