README

The library provides an Async HTTP client for making HTTP request. It uses PHP streams API for send request to resource servers, there must only be used in environment that support PHP streams and sockets APIs.

Usage

To send HTTP request using this library, follow the examples below:

use function Drewlabs\Async\Future\await;
use function Drewlabs\Async\Http\createRequest;
use function Drewlabs\Async\Http\fetch;

// Creates the fetch client
$promise = fetch(createRequest('http://www.dneonline.com/calculator.asmx?wsdl', 'GET', null, []), ['debug' => true]); // Debugging should not be used in production

$response = await($promise);
printf("Content-Length: %d\n\r", strlen($response->getBody()));

If one is familiar which async syntax, one might do the following:

use function Drewlabs\Async\Http\createRequest;
use function Drewlabs\Async\Http\fetch;

// Creates the fetch client
$promise = fetch(createRequest('http://www.dneonline.com/calculator.asmx?wsdl', 'GET', null, []), ['debug' => true]); // Debugging should not be used in production

// Provide then handlers
$promise->then(function($response) {
	printf($response->getBody());
	printf($response->getStatusCode());
});

// wait for request to complete response
$promise->wait();

API

• createRequest createRequest(string $url, string $method = 'GET', ?string $body = '', $headers = []) This function is used to create a request instance compatible with the fetch interface

• createResponse createResponse(string $body = '', int $statusCode = 200, array $headers = [], string $reasonPhrase = 'OK') Creates a response instance compatible with one returned by the fetch interface

• fetch fetch(RequestInterface $request): ResponseInterface fetch(RequestInterface[] $requests): ResponseInterface[] fetch(string $url): ResponseInterface HTTP client for sending HTTP request asynchronously.
