Wrapper for calling Restful API

wrapi allows you to call HTTP based APIs just like making calls to ordinary php functions.

Installation

Install with Composer

1. Update your composer.json to require palanik/wrapi package.
2. Run composer install to add wrapi your vendor folder.

{
  "require": {
    "palanik/wrapi": "*"
  }
}

or simply run

composer require palanik/wrapi

Easy Start

Approach I

1. Create an array listing all the API endpoints you want to work with.
2. Wrap endpoints with wrapi.
3. Call individual endpoints as functions.

See Example Code

Approach II

1. Create client object with API Base URL.
2. Register API endpoints.
3. Call individual endpoints as functions.

See Example Code

Endpoints Array

Declare each endpoint as per the following specifications.

"function_name" => array(
	"method" => "HTTP_METHOD",					// 'GET', 'POST', 'PUT', 'PATCH' or 'DELETE'
	"path" => "relative/path/to/:api/endpoint"	// Can use `Slim`/`express` style path params
)

eg. a small set of github.com API

array(
	"repo" => array(
		"method" => "GET",
		"path" => "repos/:owner/:repo"
	),

	"contributors" => array(
		"method" => "GET",
		"path" => "repos/:owner/:repo/contributors"
	),

	"languages" => array(
		"method" => "GET",
		"path" => "repos/:owner/:repo/languages"
	),

	"tags" => array(
		"method" => "GET",
		"path" => "repos/:owner/:repo/tags"
	),

	"branches" => array(
		"method" => "GET",
		"path" => "repos/:owner/:repo/branches"
	)
)

Wrap endpoints

Create a API client object from wrapi. Provide the base url for the API and the endpoints array. wrapi will create a client object with all the necessary functions.

$endpoints = array(...);

$client = new wrapi\wrapi('https://api.github.com/',	// base url for the API
  endpoints 										// your endpoints array
);

// client object contains functions to call the API

Register

Register additional API endpoints with the client object with a function name.

$client("zen", 
	array(
		"method" => "GET",
		"path" => "zen"
		)
	);

Make the call

Call the functions with arguments.

// This will make GET request to 'https://api.github.com/repos/guzzle/guzzle/contributors'
$contributors = $client->contributors('guzzle', 'guzzle');

$zenQuote = $client->zen();
echo "Today's quote: ". $zenQuote;

API

wrapi is an open ended framework and is not restricted any one or a set of public APIs. All APIs providing HTTP interface to access the endpoints can be wrapped by wrapi so that you can quickly build your client application.

Endpoint definition

method & path/url are required.

• method - Any one of the HTTP methods
• path - route path to API Endpoint. Supports express style path params
• query - an associative array with name-value pairs. This is optional. Useful where resources are identified via query string parameters
• url - fully qualified uri string to override. Useful when api calls connect to a different endpoints

Client object

The wrapi object conveniently provides the client interface to the API. Create it by calling new wrapi\wrapi().

The constructor takes the following arguments:

1. baseURL - The base url for the API. eg. https://api.github.com/repos/guzzle/guzzle/contributors
2. endpoints - The array listing the endpoints of the API. Provide an empty array or a partial list and register endpoints later.
3. options - Optional parameter. wrapi uses Guzzle module to connect to API server. The options parameter is the same options parameter used in Guzzle``request.

Register function

Add endpoints to client object.

$client(function_name, endpoint_definition)

1. function_name - Alias for the endpoint, also the name of the function to call.
2. endpoint_definition - Array defining the endpoint.

Function calls

Call the API via the function in the client object. Arguments to the function depend on the API declaration in the endpoints array.

Provide the arguments in the following order:

1. named params in the url path of the endpoint. eg. $client->contributors('guzzle', 'guzzle') // guzzle (owner) & guzzle (repo) are path params
2. querystring as an associative array with name-value pairs. eg. $client->contributors(array("since" => 364) // querystring ?since=364
3. body - JSON content for POST or PUT methods. Skip this argument if not required.
