README
This library provide tools for more clean handling responses for PHP apps running inside OpenWhisk runtime.
In raw OpenWhisk action you need to return clearly defined Array - that's missing type control and it's liitle dirty.
This library provides tools to build responses for most of usually cases (HTTP, HTML, JSON responses, etc.).
Install
composer require jakubboucek/openwhisk-runtime
Usage
Sending OpenWhisk runtime's response without this library
<?php function main(array $args) : array { $name = $args['name'] ?? 'stranger'; $greeting = "Hello $name!"; return ['body' => $greeting, 'headers' => ['Content-Type' => 'text/html; charset=utf-8']]; }
Raw Response (just only for back compatibility with OpenWhisk's raw)
<?php use JakubBoucek\OpenWhisk\Runtime\Response; function main(array $args) : array { $name = $args['name'] ?? 'stranger'; $greeting = "Hello $name!"; return new Response\RawResponse(['body' => $greeting, 'headers' => ['Content-Type' => 'text/html; charset=utf-8']]); }
Raw JSON Response (just only for back compatibility with OpenWhisk's raw)
<?php use JakubBoucek\OpenWhisk\Runtime\Response; function main(array $args) : array { $name = $args['name'] ?? 'stranger'; $greeting = "Hello $name!"; return new Response\RawJsonResponse(['message' => $greeting]); }
HTTP Response
<?php use JakubBoucek\OpenWhisk\Runtime\Response; function main(array $args) : array { if (!isset($args['name'])) { return (new Response\HttpResponse("Error: Missing required field 'name'.")) ->setStatusCode(400) ->setContentType(Response\HttpHeader::PlainContentType); } $greeting = "Hello {$args['name']}!"; return (new Response\HttpResponse($greeting)) ->setContentType(Response\HttpHeader::PlainContentType); }
HTML Response
<?php use JakubBoucek\OpenWhisk\Runtime\Response; function main(array $args) : array { $name = $args['name'] ?? 'stranger'; $greeting = sprintf('Hello <strong>%s</strong>!', htmlspecialchars($name)); return new Response\HtmlResponse($greeting); }
JSON Response
<?php use JakubBoucek\OpenWhisk\Runtime\Response; function main(array $args) : array { if (!isset($args['name'])) { return (new Response\JsonResponse(['error' =>"Error: Missing required field 'name'.")) ->setStatusCode(400); } $greeting = "Hello {$args['name']}!"; return new Response\JsonResponse(['message' => $greeting]); }
Catching standard Output Buffer Response
<?php use JakubBoucek\OpenWhisk\Runtime\Response; use JakubBoucek\OpenWhisk\Runtime\Source; function main(array $args) : array { $response = new Response\DynamicResponse(new Source\OutputBuffer()); echo 'Dumping $args variable:' . "\n"; var_dump($args); return $response; }
