It provides request, response, URI, uploaded file, and stream objects that work with Guzzle and any other library using the PSR-7 interfaces. Use this package directly when you need to create or inspect PSR-7 messages without sending HTTP requests. If you only want to make HTTP requests, install [`guzzlehttp/guzzle`](https://github.com/guzzle/guzzle/blob/8.0/README.md)instead; it already depends on this package. Installation ------------ [](#installation) ``` composer require guzzlehttp/psr7 ``` Version Guidance ---------------- [](#version-guidance) VersionStatusPHP Version3.0Latest>=7.4,<8.62.13Maintenance>=7.2.5,<8.61.9End of Life>=5.4,<8.2Quick Start ----------- [](#quick-start) ``` use GuzzleHttp\Psr7\Request; use GuzzleHttp\Psr7\Response; use GuzzleHttp\Psr7\Utils; $request = new Request('GET', 'https://example.com/api'); $response = new Response(200, ['Content-Type' => 'text/plain'], 'OK'); $stream = Utils::streamFor('request or response body'); echo $request->getMethod(); echo $response->getStatusCode(); echo $stream; ``` PSR-7 messages and URIs are immutable. Methods such as `withHeader()` and `withUri()` return a changed copy instead of modifying the original object. Streams are mutable body handles; reading, writing, seeking, and closing a stream can change its cursor, contents, or usability. ``` $request = $request->withHeader('Accept', 'application/json'); ``` Documentation ------------- [](#documentation) - [PSR-7 Messages](docs/psr-7-messages.md) - [Streams and Decorators](docs/streams-and-decorators.md) - [URI Helpers](docs/uri-helpers.md) - [PSR-17 Factories](docs/psr-17-factories.md) - [Message Helpers](docs/message-helpers.md) - [Diagnostic Values](docs/diagnostic-values.md) - [Header and Query Helpers](docs/header-and-query-helpers.md) - [Stream Helpers](docs/stream-helpers.md) - [URI and MIME Helpers](docs/uri-and-mime-helpers.md) - [Upgrade Guide](UPGRADING.md) - [Changelog](CHANGELOG.md) Security -------- [](#security) If you discover a security vulnerability within this package, please send an email to .
