Testing Endpoints with Postman

We can test GET endpoints directly in the browser.

Browser Test

  • We can also POST with an HTML form, but other HTTP methods require JavaScript to execute.

Another tool for interacting with a server is curl, a command-line client for requesting URLs.

curl -X GET http://localhost:8080/ping
pong
  • curl can execute any HTTP request method, reading request body content from a file or the command line, allows setting of request headers and many other options, and works with a wide variety of protocols.
