Getting started with API - How?


V
 Share

Recommended Posts

I'm trying to learn how to create a simple API, possibly using REST. I found a lot of online tutorials on how to implement API's but how do I create my own for my own website?

 

The API I want to make is just for querying simple data and inserting data in the DB.

 

From what I learned, REST does HTTP requests from a XML or JSON file but is REST a script I have to download, I can't find a REST site. I'm confused..  :-\

An rss feed is an API, its really that simple - you can make it any type of application

 

http://site.com/example.php: (on your site)

 

<?php

$go = $_GET['q'];

echo $go;

?>

 

On the developers site

 

echo file_get_contents('http://site.com/example.php?q=funny');

 

Which will output "funny" on the developers site

 

Thats all an API is

REST uses HTTP which makes it very lightweight, a few examples of REST:

 

-- create the user

 

PUT /users

Host: www.phpfreaks.com

Accept: text/xml

Accept-Encoding: UTF-8

 

username=ignace&password=password

 

-- read the user info

 

GET /users/ignace

Host: www.phpfreaks.com

Accept: text/xml

Accept-Encoding: UTF-8

Authorization: user ignace:password

 

-- update the profile info

 

POST /users/ignace

Host: www.phpfreaks.com

Accept: text/xml

Accept-Encoding: UTF-8

Authorization: user ignace:password

 

avatar=RESTful.jpg&signature=Posted%20Using%20REST

 

-- delete it

 

DELETE /users/ignace

Host: www.phpfreaks.com

Accept: text/xml

Accept-Encoding: UTF-8

Authorization: user ignace:password

 

Full CRUD-functionality.

you can't get a REST tutorial for an API that doesn't exist!

the fact is your attempting to write something that's going to be unique to your site, with the info above, I'm not sure what else your need, other then working out what you need to access via the API and what inputs and outputs your going to be using

MadTechie yes that makes sense. I'm just trying to find a very basic API example using the REST method and from then I can figure out how to develop my own.

 

There's no (easy to understand) documentation on it, yet everyone says it's simple.. :(

Yes, just insert into the DB and query from the DB

Well Insert is a query !?! but anyways

 

Create 2 a script that accepts 3 parameters (List, Add, Name)

/index.php?List=Usernames

Would be used to list all users

 

/index.php?Add=Username&Name=MadTechie

would be used to Add a User
