Conflux HTTP

Conflux HTTP — This is a flexible architecture for integration with external HTTP services, built on the basis of the PSR-18 and Guzzle. Each request is made out as a separate class that implements the necessary interfaces, providing readability, testability and expansion.

Requirements

• PHP 8.3 or higher.

Installation

The package could be installed with Composer:

composer require uzdevid/conflux-http

Quick start

1. Configuration

class GithubConfig implements UzDevid\Conflux\Http\ConfigInterface {
    public function getClient(): ClientInterface {
        return new GuzzleHttp\Client;
    }

    public function getBaseUri(): string {
        return 'https://api.github.com';
    }

    public function getDefaultHeaders(): array {
        return ['Accept' => 'application/json'];
    }
}

2. Create request class

use UzDevid\Conflux\Http\Request\RequestInterface;
use UzDevid\Conflux\Http\Request\RequestQueryInterface;
use UzDevid\Conflux\Http\Request\RequestBodyInterface;
use UzDevid\Conflux\Http\Request\ConvertableBodyInterface;
use UzDevid\Conflux\Http\Request\Method;
use UzDevid\Conflux\Http\Parser\JsonParser;

class GetUser implements RequestInterface, RequestQueryInterface, ConvertableBodyInterface {
    use JsonParser;
    
    public function getMethod(): Method {
        return Method::GET;
    }

    public function getUrl(): string {
        return '/users/{id}';
    }

    public function getQueryParams(): array {
        return [];
    }

    public function getQueryPath(): array {
        return ['{id}' => 123];
    }

    public function convert(array $response): UserDto {
        return new UserDto($response);
    }
}

3. Send request

use UzDevid\Conflux\Http\ConfluxHttp;
use \Yiisoft\EventDispatcher\Dispatcher\Dispatcher;

$config = new GithubConfig();
$conflux = new ConfluxHttp($config, new RequestHandler(), new Dispatcher();
$response = $conflux->withRequest(new GetUser())->send(); // UserDto

Implemented request interfaces

RequestInterface

Mandatory interface, sets the method, path and parser answer:

interface RequestInterface {
    public function getMethod(): Method|string;
    public function getUrl(): string;
    public function parse(string $content): array;
}

You can use trait Uzdevid\Conflux\Http\Parser\JsonParser to pars the answers in JSON format

RequestQueryInterface

If you need to send the query parameters or specify them to the URL:

interface RequestQueryInterface {
    public function getQueryParams(): array;
    public function getQueryPath(): array;
}

RequestBodyInterface

If you need send body (POST, PUT etc.):

interface RequestBodyInterface {
    public function getOption(): Option; // Например, 'json', 'form_params'
    public function getBody(): array|string;
}

RequestHeadersInterface

Custom headers:

interface RequestHeadersInterface {
    public function getHeaders(): array;
}

ConvertableBodyInterface

If after parsing the body needs to be converted into an object:

interface ConvertableBodyInterface {
    public function convert(array $response): mixed;
}

---

Example with POST request and body:

class CreateUser implements RequestInterface, RequestBodyInterface {
    use JsonParser;
    
    public function getMethod(): Method {
        return Method::POST;
    }

    public function getUrl(): string {
        return '/users';
    }

    public function getOption(): Option|string {
        return 'json';
    }

    public function getBody(): array|string {
        return ['name' => 'John', 'email' => 'john@example.com'];
    }
}

---

URL replacement

If the getUrl() contains the placeholders {}, they will be automatically replaced by values from getQueryPath().

getUrl(): '/users/{id}'
getQueryPath(): ['{id}' => 5]

Result: GET /users/5

---

Handle events

You can subscribe to the events of BeforeRequest, AfterRequest and OnThrow using the EventDispatcherInterface from the package yiisoft/event-dispatcher
