I was part of CRIO-Winter of doing and I learned about curl and it’s super awesome to have a tool like that. Although there are tools like postman now-s-days curl was invented way back in 1997 that can be used in Linux terminal.
- Introduction:
CURL is Client URL which is a command line tool used to send and get HTTP requests for debugging or testing while you are developing or using Api’s .
Commands:
curl https://www.google.comThe above command is by default a GET command where the response is displayed in the form of HTML.
curl -o store.html https://www.google.comThe above command is used to push the content into a file like store.html and you can retrieve the data using the below command.
cat store.html For printing response headers the below command can be used
curl -i -X GET http://www.flipkart.com- Response:
