README

Provides objects describing HTTP requests and responses as well as the ability to send HTTP requests. The request and response classes are extended by the rest-api package, which uses them to represent incoming REST API requests and responses.

👀🌋 This Is A Module Of The Caldera Framework

Overview

Request and response have the following public APIs

Request Only:

  • getParam($name) - Get the value of a request body (or query argument) field.
  • getParams() - Get the values of all request body (or query argument) fields.
  • setParam($name,$value) - Set the value of a request or response body (or query argument) field.

Response Only:

  • getData() - Get the values of all request body (or query argument) fields.
  • getStatus() - Set the request HTTP method.
  • getStatus($code) - Set the HTTP status method.

Request and Response

  • getHeader($name) - Get the value of a request or response header.
  • getHeaders() - Get the values of a all request or response headers.
  • setHeader($name,$value) - Set the name of a request or response header.
  • getHttpMethod - Get the request HTTP method.
  • setHttpMethod - Set the request HTTP method.

Usage

Main module class methods:

  • send() - Send an HTTP request to the specified URL.
    • Supply a Request object and a URL. The response will be returned, represented by a Response object.
    • Uses Guzzle by default.
  • setClient() Reset the HTTP client.
    • Useful for testing. There is an example in the phpunit cheatsheat
    • Could be used to add a different HTTP transport or something that pretends to be HTTP.

There are other public methods. They really should get moved to another class, as this class. Don't use them please.

Install

  • Add to your package:
    • composer require calderawp/http
  • Install for development:
    • git clone git@github.com:CalderaWP/http.git && composer install

Using

  • Access from main container:
$http = \caldera()->getHttp(); 
  • Reset Client
        use GuzzleHttp\Handler\MockHandler;
        use GuzzleHttp\HandlerStack;
        use GuzzleHttp\Psr7\Response;
        
        //...
        
        $mockResponse = new Response(200, ['X-HELLO' => 'ROY'],
			json_encode(['messageFromServer' => 'Everything Is An Illusion.']));
		$mock = new MockHandler([
			$mockResponse,
		]);
		$handler = HandlerStack::create($mock);
		$client = new Client(['handler' => $handler]);
		\caldera()->getHttp()->setClient($client);

Making A Remote HTTP Request

All HTTP requests are represented by the objects of the Request class and then passed to CalderaHttp::send()

  • Create An Request Object First, you need to create a request object:
$apiRequest = new \calderawp\caldera\Http\Request();
$apiRequest->setHttpMethod('POST'); //how to dispatch 
$apiRequest->setParams([ 'stateOfMind' => 'Super Chill' ); //Request body
$apiRequest->setHeaders([ 'X-CONTENT-TYPE' => 'application/json' ] ); //Request headers
  • Dispatch Request Object Then you can dispatch your request. If the request is invalid and exception may be thrown -- by CalderaHttp or Guzzle. A generic catch is recommenced:
try {
    $response = \caldera()
        ->getHttp()
        ->send($apiRequest, $url);
} catch (\Exception $e) {
    throw  $e;
}
  • Using The Response
$status = $response->getHeaders(); //All headers returned by remote API
$status = $response->getStatus(); //status code returned
$body = $response->getData();// body of remote request response

Testing

  • Run all tests (JK, just unit tests because that's the pattern)
    • composer test
  • Run unit tests
    • composer test:unit
  • Run acceptance tests
    • composer test:acceptance
