Introduction

Bundle provides possibility for validate data according to the Swagger 2 documentation. You describe your API documentation by Swagger and provides verification of data for compliance with the described requirements. When documentation has been updated then verification will be updated too, all in one place!

Documentation is cached through the standard Symfony Warmers mechanism. In debug mode, the cache automatically warms up if you change the file containing the description of the documentation.

Note: as result bundle returns SwaggerResolver object - extension for the OptionsResolver. In this way you get full control over created resolver.

Attention: remember, when you change generated SwaggerResolver object you risk getting divergence with actual documentation.

Integrations

Bundle provides integration with NelmioApiDocBundle, supports configuration loading by swagger-php and also supports loading directly from the json or yaml(yml) configuration file. When used default bundle configuration then swagger documentation will be load in most optimal available way. Loaders priority:

NelmioApiDocBundle - do not require any additional configuration.
swagger-php - scan src/ directory by default. Uses swagger_php.scan and swagger_php.exclude parameters.
json - looking for web/swagger.json by default. Uses configuration_file parameter.

Installation

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

    composer require adrenalinkin/swagger-resolver-bundle

is command requires you to have Composer install globally.

Step 2: Enable the Bundle

Then, enable the bundle by updating your app/AppKernel.php file to enable the bundle:

<?php declare(strict_types=1);
// app/AppKernel.php

class AppKernel extends Kernel
{
    // ...

    public function registerBundles()
    {
        $bundles = [
            // ...

            new Linkin\Bundle\SwaggerResolverBundle\LinkinSwaggerResolverBundle(),
        ];

        return $bundles;
    }

    // ...
}

Configuration

To start using bundle you don't need to define some additional configuration. All parameters have values by default:

# app/config.yml
linkin_swagger_resolver:
    # default parameter locations which can apply normalization
    enable_normalization:
        - 'query'
        - 'path'
        - 'header'
    # strategy for merge all request parameters.
    path_merge_strategy:            Linkin\Bundle\SwaggerResolverBundle\Merger\Strategy\StrictMergeStrategy
    configuration_loader_service:   ~   # the name of the configuration loader service
    configuration_file:             ~   # full path to the configuration file
    swagger_php:                        # settings for the swagger-php
        scan:       ~                   # array of the full paths for the annotations scan
        exclude:    ~                   # array of the full paths which should be excluded

Usage

Step 1: Swagger documentation preparation

Swagger documentation preparation differ according to used tools of your project.

NelmioApiDocBundle

If your project has NelmioApiDocBundle connected, then no additional configuration is required.

swagger-php

In the absence of NelmioApiDocBundle, the bundle will degrade to the configuration loading by swagger-php annotations. In this case, by default, will be used src/ directory to scan. To optimize scanning process you can describe directories in the configuration:

# app/config.yml
linkin_swagger_resolver:
    swagger_php:
        scan:
            - '%kernel.project_dir%/src/Acme/ApiBundle'
        exclude:
            - '%kernel.project_dir%/src/Acme/ApiBundle/Resources'
            - '%kernel.project_dir%/src/Acme/ApiBundle/Repository'

JSON

In the absence of NelmioApiDocBundle and swagger-php, the bundle will degrade to the configuration loading by json file. In this case, by default, will be used web/swagger.json file. Also, you can set custom path to the json configuration:

# app/config.yml
linkin_swagger_resolver:
    configuration_file: '%kernel.project_dir%/web/swagger.json' # json extension is required

YAML or (yml)

In the absence of NelmioApiDocBundle and swagger-php, but available configuration file in the yaml or yml format you need to define path to that file:

# app/config.yml
linkin_swagger_resolver:
    configuration_file: '%kernel.project_dir%/web/swagger.yaml' # yaml or yml extension is required

Custom

If you need to use custom configuration loader you should implement custom loading process in the class, which implements SwaggerConfigurationLoaderInterface interface. After that you need to define name of that service in the configuration:

# app/config.yml
linkin_swagger_resolver:
    configuration_loader_service: acme_app.custom_configuration_loader

Step 2: Data validation

Validation for model

<?php declare(strict_types=1);

/** @var \Linkin\Bundle\SwaggerResolverBundle\Factory\SwaggerResolverFactory $factory */
$factory = $container->get('linkin_swagger_resolver.factory');
// loading by fully qualified class name
$swaggerResolver = $factory->createForDefinition(AcmeApiModel::class);
// loading by class name
$swaggerResolver = $factory->createForDefinition('AcmeApiModel');

/** @var \Symfony\Component\HttpFoundation\Request $request */
$data = $swaggerResolver->resolve(json_decode($request->getContent(), true));

Validation for request

<?php declare(strict_types=1);

/** @var \Linkin\Bundle\SwaggerResolverBundle\Factory\SwaggerResolverFactory $factory */
$factory = $container->get('linkin_swagger_resolver.factory');
$request = $container->get('request_stack')->getCurrentRequest();
// Loading by request
$swaggerResolver = $factory->createForRequest($request);

$data = $swaggerResolver->resolve(json_decode($request->getContent(), true));

Advanced

Custom validator

Bundle validates the data through the validator system. List of all validators, you can find out by going to the Validator folder. All validators registered as tagging services. To create your own validator it is enough to create class, which implements SwaggerValidatorInterface and then register it under the tag linkin_swagger_resolver.validator.

Custom normalizer

Bundle validates the data through the normalizer system. List of all normalizers, you can find out by going to the Normalizer folder. All normalizers registered as tagging services. To create your own normalizer it is enough to create class, which implements SwaggerNormalizerInterface and then register it under the tag linkin_swagger_resolver.normalizer.
