HTTP - Post

About

The POST method requests that the target resource process the representation enclosed in the request according to the resource's own specific semantics.

They are by default not cached.

Usage

• Providing a block of data, such as the fields entered into an HTML form, to a data-handling process;
• Posting a message to a bulletin board, newsgroup, mailing list, blog, or similar group of articles;
• Creating a new resource that has yet to be identified by the origin server
• Appending data to a resource's existing representation(s).

How to execute a Post request

To create and execute a post request, you can use the following element

• using an HTML form
• using a http library method such as the javascript fetch function
• using a http client such as curl
