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

For example, POST is used for the following functions (among others):

  • 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

Example

With CURL, to create a page with a title with Json data

curl -b cookie.txt \
   -d '{"page": [{"title": "Hello World"}]}' \
   -H "Content-Type: application/json" \
   -H "Origin: https://mywebsite.com" \
   https://api-host.com/api/posts

Management

  • a 201 (Created) response
  • containing a Location header field that provides an identifier for the primary resource created

Cache

Responses to POST requests are only cacheable when they include explicit freshness information
