JSON RPC Framework (JRF)
========================

[](#json-rpc-framework-jrf)

[![Build Status](https://camo.githubusercontent.com/acd1e7ee1ca49f2d7332ea07948726d049f41c8cca3704460d60aaf27f589409/68747470733a2f2f7472617669732d63692e6f72672f72616d626c65722d6469676974616c2d736f6c7574696f6e732f4a52462e737667)](https://travis-ci.org/rambler-digital-solutions/JRF)

**JRF** is a **JSON-RPC over HTTP** data providing framework. Simple component-based architecture allow you to fast and easy web service developing. From the box (as-is) **JRF** supports a controller/action factory, input interface (PhpInput by default), and MiddleWare request checking.

SchemaChecker interface allow to hint-and-check incoming params for any method provided by yours application service.

Smart-fault interface is very easy to use. You don't need to care about anything low-level lifecycle catchers and response result builders. Just raise and see =)

Outside of the box, you can create a powerful controller-based application service with controller factory.

Usage example
=============

[](#usage-example)

```
use \jrf\JRF;
$service = new JRF();

$service->controller()->handleMethod('method',
    function($param_1, $param_2, JRF $app, $request_id) {
        return $param_1 + $param_2
    });

$service->listen();
```

Just post JSON on it:

```
{
    "jsonrpc": "2.0",
    "id": 100,
    "method": "method",
    "params": [1, 3]
}
```

Overriding input interface
==========================

[](#overriding-input-interface)

If php://input is a bad way for you, you can create your own input:

```
use jrf\http\Input;

class MyInput extends Input
{
    private $input;

    public function __construct($input)
    {
        $this->input = $input;
    }

    public function read()
    {
        return $this->input;
    }
}
```

And override default like this:

```
// ..... service init
use MyInput;
$input = new MyInput($_POST['json']);
$service->request()->setInputProvider($input);
```

All done =) Your provider will work fine inside JRF ecosystem.

Create access middleware
========================

[](#create-access-middleware)

In "captain obvious" opinion, all available private service must have access provisioning module. Let's code-in it:

```
use \jrf\middleware\Base;
use \jrf\fault\ServerError;

class AccessMiddleware extends Base
{
	private $ip_list=[];
	public function __construct(array $ip_list) {
		$this->ip_list = $ip_list;
	}

	public function call()
	{
		$info = $this->app->request()->info();
		$ip   = $info['ip_address'];

		if (!in_array($ip, $this->ip_list)) {
		    ServerError::raise('access error');
		}

		$this->next->call();
	}
}
```

Let's add our middleware into service:

```
// ... service init
use AccessMiddleware;

$list_allowed_ip = ['127.0.0.1'];

$service->add(new AccessMiddleware($list_allowed_ip));
```

Create custom controller factory
--------------------------------

[](#create-custom-controller-factory)

Simple and easy way to create factory - use namespace-based action provider.

```
use jrf\controller\Base;
use jrf\fault\MethodNotFound;

class MyControllerFactory extends Base
{
    public function runMethodWithArgs($method, array $args =[], $request_id=0)
    {
        // fall-back if want to use closure-based methods
        if ($this->isHandledMethod($method)) {
            return parent::runMethodWithArgs($method, $args, $request_id);
        }

        // now try to create action class
        if (strpos('.', $method)===false) {
            MethodNotFound::raise();
        }

        list($group, $action) = explode('.', $method);

        $class_name = sprint_f("\my\action\namespace\%s\%s", strtolower($group), ucfirst($action));

        if (!class_exists($class_name)) {
            MethodNotFound::raise();
        }

        $action = new $class_name($this->app());

        if (!is_callable([$action, 'run'])) {
            MethodNotFound::raise();
        }

        return $action->run();
    }
}
```

Implementation:

```
// .... service init
use MyControllerFactory;
$factory = new MyControllerFactory;
$service->controller($factory);
```

Incoming params hinting/checking
--------------------------------

[](#incoming-params-hintingchecking)

For example, json was posted is:

```
{
    "jsonrpc":"2.0",
    "id":120,
    "method":"test",
    "params":{
        "a":11,
        "b":10
    }
}
```

Rules:

- a > 0
- b > 0
- a is INT
- b is INT
- a REQUIRED
- b REQUIRED

Implementation

```
use jrf\json\Schema;

$params_definition = [
    'a' => [
        'type' => Schema::TYPE_INT,
        'definition' => Schema::DEFINITION_REQUIRED,
        'expression' => function ($v) { return intval($v) > 0; }
    ],
    'b' => [
        'type' => Schema::TYPE_INT,
        'definition' => Schema::DEFINITION_REQUIRED,
        'expression' => function ($v) { return intval($v) > 0; }
    ],
];

$schema = new Schema($params_definition);
$service->controller()->setSchemaForMethod('test', $schema);
```

Configuration container
-----------------------

[](#configuration-container)

Configuration Container instantiated Inside JRF constructor method with options passed inside it. To access container JRF provide method named "config", config access examples:

```
use jrf\JRF;

$options = [
    'app.debug' => true,
    'app.secret' => 'secret'
];

$service = new JRF($options);

// return: null
$val = $service->config('unknown-option');

// return default defined value: 123
$val = $service->config('unknown-option', 123);

// return true
$val = $service->config('app.debug');
$val = $service->config('app.debug', false);
$val = $service->config()->get('app.debug');
$val = $service->config()->{'app.debug'};
$val = $service->config()['app.debug'];
```

Client usage
------------

[](#client-usage)

```
$client = new Client("http://json-rpc.server/");

$pipe = $client->createPipe();

$batch = $client->createBatch();
$m1_id = $batch->append($client->method('m1', [1,2,3]));
$m2_id = $batch->append($client->method('m2'));
$m3_id = $batch->append($client->method('m3'));

$pipe->add('batch', $batch);
$pipe->add('news', $client->method('news.search', ['limit'=>50]));
$pipe->add('users', $client->method('users.all', ['limit'=>10]));

$response = $client->executePipe($pipe);

$m1 = $response['batch'][$m2_id];

var_dump($m1->getResult());
var_dump($client->getTotalTime());
```

Unit Tests
----------

[](#unit-tests)

```
cd path/to/jrf-root
php composer.phar update --dev
vendor/bin/phpunit
```

No-HTTP Usage
-------------

[](#no-http-usage)

If that really needed, JRF allow to handle custom input interface without any listeners. By this way JRF is not provide response output. However, if you need to use couple of providers both, you can run service by add **$service->listen()**.

```
// input interface from example
use MyInput;

$payload = ["jsonrpc"=>"2.0", "id"=>1, "method"=>"my.method"];
$input   = new MyInput(json_encode($payload));

// ... defining service

$result_string = $service->handleInputProvider($input);
$result_array  = json_decode($result_string, true);

// if HTTP listener needed
$service->listen();
```
