SimplyREST

A micro-framework written in PHP that will help you build RESTful APIs.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Some things that you need

MySQL Server
Web Server
Composer

Installing

Make sure composer is installed on your machine and the $HOME/.composer/vendor/bin directory is in your $PATH so the srest executable can be located by your system.

Download the SimplyREST installer via composer

composer global require vinceurag/sr_installer

Initialize a new app

srest new myapi

Verify that your web server and mysql is started.

Modify config/database.php with your database details.

$db['host'] = 'localhost';
$db['user'] = 'root';
$db['password'] = '';
$db['database'] = 'test_db';

Test if it's working. Go to <server>/<directory where you put this project>/SimplyREST/ For example you're using XAMPP and you cloned this project to htdocs, you need to go to

http://localhost/myapi/

You should see something like:

{
    "status" : "successful",
    "details" : "framework was installed successfully"
}

Play around with the controllers on /api

How To Use

DO NOT MODIFY ANYTHING IN THE /core FOLDER AND index.php
SAMPLE DATABASE SCHEMA IN config/test_db.sql

Controllers

Controllers are located under /api Every controller MUST extend the SR_Controller.

This REST server supports the most common 4 HTTP Methods: GET, POST, PUT, DELETE.

When creating a function, this should be the format: HTTPMETHOD_functionname(). For example, get_name(). If the user accessed /name using the GET method, this method will be invoked. Else, if the user accessed it via POST method, the post_name will be invoked.

To send a response, use the function:

$this->sendResponse($arrayData, HTTP_Status::HTTP_OK)

$this->sendResponse() takes in two parameters, the data you want to be the response body (in array) and a status code.

Status codes are defined in core/HTTP_Status.php

HTTP_OK = 200

HTTP_CREATED = 201

HTTP_NOT_FOUND = 404

HTTP_UNAUTHORIZED = 401

To access the POST or PUT json sent to the server, use the function:

$anyVariable $this->getJsonData()

This function will return the json sent to the server in an array format.

To load the model, use the function:

$this->load("model_name")

$model_name is the class name of your model. You should load the model in your controller's constructor. To use the loaded model, you just need to append the model_name to $this->. For example, I loaded the model anothermodel in the constructor $this->load_model("anothermodel"), to access it inside the functions in my controller, I can call $this->anothermodel->getUser() assuming there is a getUser() function inside my model.

Models

Models are located under /models Every model MUST extend the SR_Model.

To make a query to the database, use the function:

$this->db->exec("SELECT * FROM tbl_users");

If the SQL statement is a SELECT statement, this function will return an array of the result (which you can directly send as a response in the controller). Else, this will return a bool.

To UPDATE a row, use the function:

$this->db->udapte_record($table, $arrayChanges, "id=condition");

If a record was successfully updated, it will return a success json.

Routes

Routes are the heart and soul of this project. It will determine which class and function will be called.

The structure of the route should always be

class_name/function_name/

Customizing Routes

You can customize the routes in the config/routes.php folder.

$route['/about'] = "test";

Here, we are routing /about to execute the get_index() of the Test class.

$route['/about/name/:param'] = "test/name";

We can also add parameters by putting :param in the place wherein we expect a parameter. This route will invoke the get_name($a) function of Test class, passing any value in place of the :param to the function.

$route['about/name/:param/age/:param'] = "test/nameage";

This project also supports multiple parameters. In this example we passed a name and age in that format. By this route, we tell our REST server to invoke the get_nameage($name, $age) method in the Test class. Also, passing the all the parameters.

Libraries

Libraries are located under /libraries

You should load the needed libraries in the constructor of the controller via the command:

$this->load("library_name")

JSON Web Token Library

The JWT Library can be used to generate a token.

To generate a token:

$this->jwt->generate_token($user_id, $arrayPayload)

$user_id is the unique identifier of the user. $arrayPayload is the custom payload you want to add to the token

To check if the user passed a VALID json web token to the authorization header:

$this->jwt->check()

If it's a valid token, it will return the decoded token and the authorization status ("authorized" or "unauthorized"). Sample response:

{
    "consumerKey": "YOUR-CONSUMER-KEY",
    "userId": 1,
    "issuedAt": "11/29/2016 00:47:42 AMNov",
    "data": {
        "name": "New Name",
        "pass": "new_pass"
    },
    "authorization": "authorized"
}

Deployment

Since some shared hosting does not read directly from the .htaccess, you may want to enter it manually or ask some help from your hosting provider.
