HTTP Multipart Form Parsing

Learn how to parse x-www-form-urlencoded or multipart/form-data data submitted to an HTTP server request handler.

This package is an add-on to amphp/http-server, which allows parsing request bodies as forms in either x-www-form-urlencoded or multipart/form-data format.


This package can be installed as a Composer dependency.

composer require amphp/http-server-form-parser


Basic usage works by calling Form::fromRequest($request), which will buffer the request body and parse it. This method may be called multiple times, so both a middleware and request handler may access the form body.

use Amp\Http\Server\FormParser\Form;
use Amp\Http\Server\Request;
use Amp\Http\Server\RequestHandler\ClosureRequestHandler;
use Amp\Http\Server\Response;
use Amp\Http\Status;

$requestHandler = new ClosureRequestHandler(function (Request $request) {
    $form = Form::fromRequest($request);

    return new Response(Status::OK, [
        "content-type" => "text/plain; charset=utf-8"
    ], $form->getValue("text") ?? "Hello, World!");

There’s also an advanced streaming parser included, StreamingFormParser, which can be used to stream uploaded files to disk or other locations.
