A guzzle middleware that can be used to validate if requests and responses match what is defined in the schema

Getting Started

Prerequisities

You'll need to install:

  • PHP (Minimum 5.6)

Installing

composer require fitbug/guzzle-swagger-validation-middleware

Usage

Simply add it to the guzzle you use as middleware.

use Fitbug\Guzzle\SwaggerValidation\SwaggerSchemaValidationHandler;
use GuzzleHttp\HandlerStack;
use Http\Adapter\Guzzle6\Client as GuzzleClientFactory;
use Http\Message\MessageFactory\GuzzleMessageFactory;

$this->messageFactory = new GuzzleMessageFactory();
$swaggerFile = 'file://';
$swaggerFile .= '/path/to/your/swagger.json';
$this->swaggerValidation = new SwaggerSchemaValidationHandler($swaggerFile);
$stack = new HandlerStack();
$stack->setHandler(GuzzleHttp\choose_handler());
$stack->push($this->swaggerValidation);
$this->httpClient = GuzzleClientFactory::createWithConfig(
    [
        'base_uri' => $apiEndpoint,
        'handler' => $stack,
    ]
);

You get output like the request or response doesn't match the specification
