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 proy (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}}
