README

The HTTP Component is a PHP library designed to simplify the process of making HTTP requests and handling HTTP responses in your applications. It follows the [PSR-7 HTTP Message Interface](https://www.php-fig.org/psr/psr-7/) standards for HTTP messages, making it compatible with other libraries and frameworks that also adhere to these standards.

Installation

You can install this library using Composer:

composer require loomlabs/http-component

Features

This HTTP Component package provides the following key features:

Request and Response Handling

• Request and Response classes that implement the Psr\Http\Message\RequestInterface and Psr\Http\Message\ResponseInterface, respectively.
• Easily create and manipulate HTTP requests and responses.
• Handle headers, request methods, status codes, and more.

Stream Handling

• A Stream class that implements the Psr\Http\Message\StreamInterface for working with stream data.
• Read and write data to streams, check for stream availability, and more.

HTTP Client

• A HttpClient class that implements the Psr\Http\Client\ClientInterface.
• Simplifies sending HTTP requests using cURL and processing HTTP responses.
• Supports common HTTP methods like GET, POST, PUT, PATCH and DELETE.
• Automatically parses response headers and handles redirects.

URI Handling

• A Uri class that implements the Psr\Http\Message\UriInterface for working with URIs.
• Easily construct and manipulate URIs, including handling scheme, host, port, path, query, and fragment.

Usage

Creating an HTTP Request

use Loom\HttpComponent\HttpClient;
use Loom\HttpComponent\Request;
use Loom\HttpComponent\StreamBuilder;
use Loom\HttpComponent\Uri;

// Create a URI
$uri = new Uri('https', 'example.com', '/');

// Create an HTTP GET request
$body = 'Some text!';
$request = new Request(
    'GET', 
    $uri, 
    ['Content-Type' => 'application/json'], 
    StreamBuilder::build($body)
);

// Customise the request headers
$request = $request->withHeader('Authorization', 'Bearer AccessToken');

// Send the request using the built-in HTTP Client
$response = (new HttpClient())->sendRequest($request);

// Get the response status code
$status = $response->getStatusCode();

// Get the response body
$body = $response->getBody()->getContents();

Creating an HTTP Client

use Loom\HttpComponent\HttpClient;

// Create an HTTP client
$client = new HttpClient();

// Send GET request
$response = $client->get('https://example.com/api/resource');

// Send POST request to endpoint with headers and body
$response = $client->post(
    'https://example.com/api/resource', 
    ['Content-Type' => 'application/json', 'Authorization' => 'Bearer AccessToken'], 
    json_encode(['data' => 'value'])
);

Working with Streams

use Loom\HttpComponent\StreamBuilder;

// Create a stream from a string
$stream = StreamBuilder::build('Hello, World!');

// Read from the stream
$data = $stream->read(1024);

// Write to the stream
$stream->write('New data to append');

// Rewind the streams internal pointer
$stream->rewind();

// Get the stream contents
$contents = $stream->getContents();

URI Handling

use Loom\HttpComponent\Uri;
use Loom\HttpComponent\Web\WebServerUri;

// Create a URI
$uri = new Uri('https', 'example.com', '/api/resource');

// Modify the URI
$uri = $uri->withScheme('http');
$uri = $uri->withPort(8888);
$uri = $uri->withQuery('new_param=new_value');

// Get the URI as a string
$uriString = $uri->__toString();

// Build a URI based on the current request to your web server
$uri = WebServerUri::generate();
