Mojio.Client

As PHP is the language of choice for many of you developers out there, we have put together a simplified client built on top of Guzzle to help you get started. This client is still very much in it's alpha stages, we appologize for any bugs and incomplete features.

Installation

Using Composer (recommended)

The client has been added to packagist under the name georgo/mojio and can be included in your project using Composer.

  1. First you will need to add "georgo/mojio" as a dependency in your composer.json file (currently only the dev-master is available, more stable versioning coming soon):

    {
        "require": {
          "georgo/mojio": "~2.0"
        }
    }
  2. Next you will need to download an install Composer and dependancies:

    curl -sS https://getcomposer.org/installer | php
    php composer.phar install
  3. Lastly, you need to include the Composer autoloader in your bootstrap:

    require '[/path/to/vendor]/autoload.php';

From Source (GitHub)

If you do not want to use Composer, you can download or checkout the complete source off github. You must also download or checkout Guzzle

Getting Started

To begin developing with Mojio PHP client, you will need your very own application ID and secret key. First you will need to create an account and login to the MOJIO developer center.

Once you have logged in, you can create a new Application. From here, you will want to copy the Application ID and the Secret Key, these will be required to initialize the MOJIO client

Initializing the Client

To get started using the client, instantiate a new instance of the MOJIO client class. This is where you will need to pass in the Application ID and Secret Key, as well as the developer environment you are using (Sandbox, or Live).

use Mojio\Api\Client;

require '[path/to/vendor]/autoload.php';

$appId = "{APPID}";
$secretKey = "{SecretKey}";

$client = Client::factory([
        'base_url' => Client::LIVE,
        'app_id' => $appId,
        'secret_key' => $secretKey
]);

// ...

Authenticate a Mojio User

Now that your MojioClient is associated with your app, you can get started making some API calls. However, many of Mojio API calls also require an authorized user to be associated with the client session. A user can grant you access using Mojio OAuth2 service, and client calls. For redirectUri, https scheme is required.

// ...

// Set the redirect URI to point to this exact same script.
$redirectUri = 'https://' . $_SERVER['HTTP_HOST'] 
                   . strtok($_SERVER['REQUEST_URI'], '?');
                   
if(!isset($_GET['code'])) {
    // Initiate an OAuth request
    header('Location: '.$client->getAuthorizationUrl($redirectUri));
    exit;
} else {
    // Handle the OAuth response
    $client->authorize($redirectUri, $_GET['code']);
}

// ...
// Logout user.
$client->logout();

Please note, you must add the $redirectUri to the allowed Redirect URIs in your application settings on the Developer Center.

Fetching Data

To retrieve a set of a particular MOJIO entities, you can use the "GET" method. The returned results will depend on what user and application your client session is authorized as. Lists of data will be returned in a paginated form. You are able to set the page size and request a particular page. In order to keep response times fast, it is recommended to keep the page size low.

// ...
// Fetch first page of 15 users
$results = $client->getTrips([
    'pageSize' => 15,
    'page' => 1
]);

foreach( $results as $trip )
{
    // Do something with each trip
    // ...
}

Fetch a specific Entity

By passing in the ID of an entity (often a GUID), you can request a single MOJIO entity from Mojio API.

// ...
$mojioId = "0a5123a0-7e70-12d1-a5k6-28db18c10200";
	
// Fetch mojio from API
$mojio = $client->getMojio([
    "id" => $mojioId
]);
	
// Do something with the mojio data
// ...

Update an Entity

If you want to update and save an entity, you need to first load the entity from the API, make your changes, and then post it back. Typically only the owner of an entity will be authorized to save changes and not all properties of an entity will be editable (for example, for an App, only the Name and Description properties can be changed).

// ...
$appId = "0a5123a0-7e70-12d1-a5k6-28db18c10200";
	
// Fetch app from API
$app = $client->getApp([
    'id' => $appId
]);
	
// Make a change
$app->Name = "New Application Name";
	
// Save the changes
$client->saveEntity([
    'entity' => $app
]);

Get a list of child entities

If you want to fetch all the entities associated with another entity, you can call the GetBy method. For example, if you want to fetch all the events associated with a particular MOJIO device.

use Mojio\Api\Model\MojioEntity;
use Mojio\Api\Model\EventEntity;

    // ...
    $mojioId = "0a5123a0-7e70-12d1-a5k6-28db18c10200";
	
    // Fetch mojio's events
    $events = $client->getList([
        "type" => MojioEntity::getType(),
        "id" => $mojioId,
        "action" => EventEntity::getType()
    ]);
	
    // Or, alternatively
    $mojio = $client->getMojio(['id' => $mojioId]);
    $events = $client->getList([
        'entity' => $mojio,
        'action' => EventEntity::getType()
    ]);

    // ...

Using the Mojio Storage

With the MOJIO API, you are able to store your own private data on Mojio servers as key value pairs. These key value pairs will only be accessible by your application, and you can associate them with any MOJIO entities (ex: MOJIO Device, Application, User, Trip, Event, Invoice, Product).

use Mojio\Api\Model\UserEntity;

    // ...
    $userId = "0a5453a0-7e70-16d1-a2w6-28dl98c10200";  // Some user's ID
    $key = "EyeColour";	// Key to store
    $value = "Brown"; 	// Value to store

    // Save user's eye colour
    $client.setStored([
        'type' => UserEntity::getType(),
        'id' => $userId,
        'key' => $key
        'value' => $value
    ]);

    // ...
    // Retrieve user's eye colour
    $client.getStored([
        'type' => UserEntity::getType(),
        'id' => $userId,
        'key' => $key
    ]);

Requesting Event Updates

Instead of continuously polling the API to check for updates, you can request Mojio API send a POST request to an endpoint of your choosing everytime certain events are received.

    $mojioId = "0a5123a0-7e70-12d1-a5k6-28db18c10200";

    $sub = SubscriptionEntity::factory(
              'IgnitionOn', // Event Type to receive
              'Mojio',      // Subscription Type
              $mojioId,     // Entity ID
              "https://my-domain-example.com/receiver.php" // Location to send events
    );

    $client->newEntity(['entity' =>$sub]);

And in your "receiver.php" file you will want to process any incoming events:

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
  $raw = file_get_contents('php://input');
  $event = json_decode( $raw );
  
  // ... Do something with the event!
}
?>
