README

This package provides functionality to persist PSR-7 HTTP Responses based on and PSR-17.

This package is designed to serialize within the PSR-7 standard. The data does not have the pre-serialized class name, so the restored class depends only on the PSR-17 Factory object passed to unserializePsr7().

Install

# minimum requirements when your project already has any HTTP library installed
composer require hakone/psr7-serializer

# for auto-detecting HTTP libraries installed in your project
composer require hakone/psr7-serializer php-http/discovery

HTTPlug Discovery (php-http/discovery) is a package useful for auto-discovering classes provided by installed HTTP libraries.

If you do not already have HTTP factory implementations installed: consider adding one of nyholm/psr7, guzzlehttp/psr7, or laminas/laminas-diactoros to your project.

Usage

<?php

use Http\Discovery\Psr17FactoryDiscovery;
use Http\Discovery\Psr18ClientDiscovery;
use function Hakone\Psr7Serializer\serializePsr7;
use function Hakone\Psr7Serializer\unserializeResponse;

// 1. Send HTTP Request
$http_client = Psr18ClientDiscovery::find();
$response = $client->sendRequest(
    Psr17FactoryDiscovery::findRequestFactory()
        ->createRequest('GET', 'http://httpbin.org/get?foo=bar')
);

// 2. Serialize and cache HTTP response
$serialized_data = serializePsr7($serializer->serializeResponse($response));
file_put_contents(__DIR__ . '/cache.txt', $serialized_data);

// 3. Load and unserialize HTTP response
$loaded_serialized_data = file_get_contents(__DIR__ . '/cache.txt');
$unserialized_response = unserializePsr7($loaded_serialized_data);

If you don't have HTTPlug Discovery installed, you must explicitly pass an instance of HTTP Factory to unserialize HTTP messages:

use Nyholm\Psr7\Factory\Psr17Factory;

$psr17Factory = new Psr17Factory();
$unserialized_response = unserializePsr7($loaded_serialized_data, $psr17Factory, $psr17Factory);

use Laminas\Diactoros\{ResponseFactory, StreamFactory};

$unserialized_response = unserializePsr7($loaded_serialized_data, new ResponseFactory(), new StreamFactory());
