HTTP methods and status codes


Let us look at the HTTP methods and status codes. The HTTP methods are a communication channel for performing operations on the HTTP protocol.

The following are the HTTP methods used:

  • GET: This gets the existing resource for a given identifier.

  • PUT: This puts a new resource.

  • POST: This updates the existing resource.

  • DELETE: This deletes the existing resource.

Status code is human readable diagnostic information about HTTP messages.
