curl

Transfers data from or to a server. Supports most protocols, including HTTP, FTP, and POP3. More information: https://curl.se.

  • Download the contents of an URL to a file:

curl {{http://example.com}} --output {{filename}}

  • Download a file, saving the output under the filename indicated by the URL:

curl --remote-name {{http://example.com/filename}}

  • Download a file, following location redirects, and automatically continuing (resuming) a previous file transfer:

curl --remote-name --location --continue-at - {{http://example.com/filename}}

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

curl --data {{'name=bob'}} {{http://example.com/form}}

  • Send a request with an extra header, using a custom HTTP method:

curl --header {{'X-My-Header: 123'}} --request {{PUT}} {{http://example.com}}

  • Send data in JSON format, specifying the appropriate content-type header:

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

  • Pass a user name and password for server authentication:

curl --user myusername:mypassword {{http://example.com}}

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

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