Guzzle Services

Provides an implementation of the Guzzle Command library that uses Guzzle service descriptions to describe web services, serialize requests, and parse responses into easy to use model structures.

use GuzzleHttp\Client;
use GuzzleHttp\Command\Guzzle\GuzzleClient;
use GuzzleHttp\Command\Guzzle\Description;

$client = new Client();
$description = new Description([
	'baseUri' => 'http://httpbin.org/',
	'operations' => [
		'testing' => [
			'httpMethod' => 'GET',
			'uri' => '/get{?foo}',
			'responseModel' => 'getResponse',
			'parameters' => [
				'foo' => [
					'type' => 'string',
					'location' => 'uri'
				],
				'bar' => [
					'type' => 'string',
					'location' => 'query'
				]
			]
		]
	],
	'models' => [
		'getResponse' => [
			'type' => 'object',
			'additionalProperties' => [
				'location' => 'json'
			]
		]
	]
]);

$guzzleClient = new GuzzleClient($client, $description);

$result = $guzzleClient->testing(['foo' => 'bar']);
echo $result['args']['foo'];
// bar

Installing

This project can be installed using Composer:

composer require guzzlehttp/guzzle-services

For Guzzle 5, use composer require guzzlehttp/guzzle-services:0.6.

Note: If Composer is not installed globally then you may need to run the preceding Composer commands using php composer.phar (where composer.phar is the path to your copy of Composer), instead of just composer.

Plugins

Change regarding PostField and PostFile

The request locations postField and postFile were removed in favor of formParam and multipart. If your description looks like

[
    'baseUri' => 'http://httpbin.org/',
    'operations' => [
        'testing' => [
            'httpMethod' => 'GET',
            'uri' => '/get{?foo}',
            'responseModel' => 'getResponse',
            'parameters' => [
                'foo' => [
                    'type' => 'string',
                    'location' => 'postField'
                ],
                'bar' => [
                    'type' => 'string',
                    'location' => 'postFile'
                ]
            ]
        ]
    ],
]

you need to change postField to formParam and postFile to multipart.

Cookbook

Changing the way query params are serialized

By default, query params are serialized using strict RFC3986 rules, using http_build_query method. With this, array params are serialized this way:

$client->myMethod(['foo' => ['bar', 'baz']]);

// Query params will be foo[0]=bar&foo[1]=baz

However, a lot of APIs in the wild require the numeric indices to be removed, so that the query params end up being foo[]=bar&foo[]=baz. You can easily change the behaviour by creating your own serializer and overriding the "query" request location:

use GuzzleHttp\Command\Guzzle\GuzzleClient;
use GuzzleHttp\Command\Guzzle\RequestLocation\QueryLocation;
use GuzzleHttp\Command\Guzzle\QuerySerializer\Rfc3986Serializer;
use GuzzleHttp\Command\Guzzle\Serializer;

$queryLocation   = new QueryLocation('query', new Rfc3986Serializer(true));
$serializer      = new Serializer($description, ['query' => $queryLocation]);
$guzzleClient    = new GuzzleClient($client, $description, $serializer);

You can also create your own serializer if you have specific needs.
