An advanced async HTTP server library for PHP, perfect for real-time apps and APIs with high concurrency demands.
Full Changelog: https://github.com/amphp/http-server/compare/v3.3.0...v3.3.1
RequestBody now implements Stringable so the entire request body can be buffered by simply casting the object to a string (note the request body length limits still apply).ClientException now extends Amp\ByteStream\StreamException to avoid violating the ReadableStream interface by throwing a non-StreamException from a stream method.Full Changelog: https://github.com/amphp/http-server/compare/v3.2.0...v3.3.0

Stable release compatible with AMPHP v3 and fibers! 🎉
As with other libraries compatible with AMPHP v3, most cases of parameters or returns of Promise<ResolutionType> have been replaced with ResolutionType.
The RequestHandler and Middleware interfaces along with the Request and Response objects are largely unchanged with the exception of replacing Promise objects with the resolution type.
RequestHandler::handleRequest() and Middleware::handleRequest() has changed from Promise<Response> to Response.ReadableStream or a string (note the interface name change in amphp/byte-stream). null will no longer be cast to an empty body.Initializing a server has changed significantly.
The Options object has been removed, replaced by constructor parameters on various components. PHP 8.0's named parameters allows only defining the parameters you wish to override without the need to define those you do not wish to change.
HttpServer is now an interface. ServerObserver has been removed and replaced with onStart() and onStop() methods on the HttpServer interface. SocketHttpServer is the provided default implementation of HttpServer. The methods getLogger(), getRequestHandler(), and getErrorHandler() are no longer part of HttpServer to avoid the interface being used as a service-locator.
In addition to the constructor, SocketHttpServer provides two convenience static constructors for common use-cases.
createForDirectAccess() — Creates an instance appropriate for direct access by the publiccreateForBehindProxy() — Creates an instance appropriate for use when behind a proxy service such as nginx'Listening interfaces are provided to SocketHttpServer using the expose() method. The RequestHandler and ErrorHandler instances are not provided to the constructor, instead being provided to the SocketHttpServer::start() method. As these objects are provided after constructing the HttpServer instance, RequestHandlers may now require an instance of HttpServer in their constructors to attach start and stop handlers.
SocketServer instances are then created by SocketHttpServer using an instance of SocketServerFactory passed to the constructor. This allows server bind contexts to be initialized based on the provided (or default) HttpDriverFactory.
Below is the "Hello, World!" example from examples/hello-world.php as an example of initializing a SocketHttpServer instance.
<?php
require dirname(__DIR__) . "/vendor/autoload.php";

// Run this script, then visit http://localhost:1337/ or https://localhost:1338/ in your browser.
$cert = new Socket\Certificate(__DIR__ . '/../test/server.pem');
$context = (new Socket\BindContext)
->withTlsContext((new Socket\ServerTlsContext)
->withDefaultCertificate($cert));
$logHandler = new StreamHandler(ByteStream\getStdout());
$logHandler->pushProcessor(new PsrLogMessageProcessor());
$logHandler->setFormatter(new ConsoleFormatter());
$logger = new Logger('server');
$logger->pushHandler($logHandler);
$logger->useLoggingLoopDetection(false);
$server = new SocketHttpServer(
$logger,
new Socket\ResourceServerSocketFactory(),
new SocketClientFactory($logger),
);
$server->expose("0.0.0.0:1337");
$server->expose("[::]:1337");
$server->expose("0.0.0.0:1338", $context);
$server->expose("[::]:1338", $context);
$server->start(new class implements RequestHandler {
public function handleRequest(Request $request): Response
{
return new Response(
status: HttpStatus::OK,
headers: ["content-type" => "text/plain; charset=utf-8"],
body: "Hello, World!",
);
}
}, new DefaultErrorHandler());
// Await a termination signal to be received.
$signal = trapSignal([SIGHUP, SIGINT, SIGQUIT, SIGTERM]);
$logger->info(sprintf("Received signal %d, stopping HTTP server", $signal));
$server->stop();
ConcurrencyLimitingMiddleware to limit the number of requests which may be concurrently handled by the server.ForwardedMiddleware and associated Forwarded class and ForwardedHeaderType enum. This middleware parses either Forwarded or X-Forwarded-For headers to determine the original client address when used behind a proxy supporting these headers.AllowedMethodsMiddleware which limits the allowed HTTP verbs used by requests. This middleware is used automatically by SocketHttpServer. The allowed methods can be specified through a constructor parameter, using null to disable the middleware.Generally consumers of this library need not worry about these changes unless they implemented their own HTTP driver or interacted with the Client interface beyond grabbing client metadata.
Client is a significantly thinner interface, consisting of only metadata about the client connection.HttpDriver instances now handle responding to requests instead of the Client object.HttpDriver::setup() has been replaced with HttpDriver::handleClient. Rather than returning a Generator parser which is fed data read from the client, this method is instead expected to read/write data from the provided streams itself.HttpDriver::write() has been removed, as writing to the client should be handled internally within the driver.SocketHttpServer
createForDirectAccess() — Creates an instance appropriate for direct access by the publiccreateForBehindProxy() — Creates an instance appropriate for use when behind a proxy service such as nginx'SocketHttpServer has changed to require an instance of ServerSocketFactory and ClientFactory, as well as accepting an array of middleware and a list of allowed HTTP methods. Use SocketHttpServer::createForDirectAccess() to create a server with similar defaults as the previous constructor.ForwardedMiddleware and associated Forwarded class and ForwardedHeaderType enum. This middleware parses either Forwarded or X-Forwarded-For headers to determine the original client address when used behind a proxy supporting these headers.AllowedMethodsMiddleware which limits the allowed HTTP verbs used by requests. This middleware is used automatically by SocketHttpServer. The allowed methods can be specified through a constructor parameter, using null to disable the middleware.$allowedMethods argument from the constructors of HttpDriverFactory, Http1Driver, and Http2Driver since this functionality is now handled by the middleware above.Request to get individual query keys in a manner similar to headers.2.0 of amphp/socket.SocketHttpServer::expose() in addition to a SocketAddress instance.Response::onDispose() being invoked as soon as the client connection or stream is closed. Prior it was not invoked until another chunk was read from the response body.v2.0 of amphp/byte-stream by updating ReadableStream implementations to also implement Traversable.Note: 3.0.0 Beta 5 was skipped due to the tag missing a commit to update UpgradedSocket to be iterable.
