HTTP POST data to an API

Published on: September 2, 2018

Welcome to the 16th Easy jQuery tutorial! We are still on AJAX and today we cover the HTTP POST method with $.ajax()

POST allows you to send data to an API end point as a "write" - meaning you are asking the server to add new data. This is the C in CRUD. Create. 

Sure, you can send data to be written using GET, but using HTTP POST is also much safer than using GET because the data is not being sent via the URL query string, instead it's being sent in the body of the request. It ensures no one can read the sent request easily. 

Here's a quick example of the HTTP POST used in the video:

        url: 'http://localhost:3000/api/tutorials',
        method: 'POST',
        dataType: 'json',
        data: {
            tutorialNumber: 4,
            title: 'fourth tutorial',
            author: 'Nazmus',
            type: 'Excel'
        }, success: function(data) {

The properties of $.ajax() is the same as GETting data. The only difference is that the method has been changed to POST, and we are sending more data back to write to the database. 

Check out the AJAX GET tutorial for an explanation of all the properties.

Since this tutorial was done in Brackets, there is no JS Fiddle. This description will be updated after the AJAX series has been completed and I've uploaded the files in the resources section below.
