Discogs Api

Build Status Latest Stable Version Total Downloads License Quality

This library is a PHP 5.4 implementation of the Discogs API v2.0. The Discogs API is a REST-based interface. By using this library you don't have to worry about communicating with the API: all the hard work has already be done.

This API is build upon the shoulders of a giant: Guzzle 4.0. This is an absolutely awesome library.

Installation

Start by installing composer. Next do:

$ composer require ricbra/php-discogs-api

Requirements

PHP >=5.4.0

Usage

Creating a new instance is as simple as:

<?php
$client = Discogs\ClientFactory::factory([]);

User-Agent

Discogs requires that you supply a User-Agent. You can do this easily:

<?php
$client = Discogs\ClientFactory::factory([
    'defaults' => [
        'headers' => ['User-Agent' => 'your-app-name/0.1 +https://www.awesomesite.com'],
    ]
]);

Throttling

Discogs doesn't like it when you hit their API at a too high connection rate. Use the ThrottleSubscriber to prevent getting errors or banned:

<?php

$client = Discogs\ClientFactory::factory();
$client->getHttpClient()->getEmitter()->attach(new Discogs\Subscriber\ThrottleSubscriber());

Authentication

Discogs API allow to access protected endpoints with either a simple Discogs Auth Flow or a more advanced (and more complex) Oauth Flow

Discogs Auth

As stated in the Discogs Authentication documentation:

In order to access protected endpoints, you’ll need to register for either a consumer key and secret or user token, depending on your situation:

  • To easily access your own user account information, use a User token.
  • To get access to an endpoint that requires authentication and build 3rd party apps, use a Consumer Key and Secret.

With the Discogs Php API you can add your credentials to each request by adding a query key to your own defaults like this:

$client = ClientFactory::factory([
    'defaults' => [
        'query' => [
            'key' => 'my-key',
            'secret' => 'my-secret',
        ],
    ]
]);

OAuth

There are a lot of endpoints which require OAuth. Lucky for you using Guzzle this is peanuts. If you're having trouble obtaining the token and token_secret, please check out my example implementation.

<?php

$client = Discogs\ClientFactory::factory([]);
$oauth = new GuzzleHttp\Subscriber\Oauth\Oauth1([
    'consumer_key'    => $consumerKey, // from Discogs developer page
    'consumer_secret' => $consumerSecret, // from Discogs developer page
    'token'           => $token['oauth_token'], // get this using a OAuth library
    'token_secret'    => $token['oauth_token_secret'] // get this using a OAuth library
]);
$client->getHttpClient()->getEmitter()->attach($oauth);

$response = $client->search([
    'q' => 'searchstring'
]);

History

Another cool plugin is the History plugin:

<?php

$client = Discogs\ClientFactory::factory([]);
$history = new GuzzleHttp\Subscriber\History();
$client->getHttpClient()->getEmitter()->attach($history);

$response = $client->search([
    'q' => 'searchstring'
]);

foreach ($history as $row) {
    print (string) $row['request'];
    print (string) $row['response'];
}

More info and plugins

For more information about Guzzle and its plugins checkout the docs.

Perform a search:

Per august 2014 a signed OAuth request is required for this endpoint.

<?php

$response = $client->search([
    'q' => 'Meagashira'
]);
// Loop through results
foreach ($response['results'] as $result) {
    var_dump($result['title']);
}
// Pagination data
var_dump($response['pagination']);

// Dump all data
var_dump($response->toArray());

Get information about a label:

<?php

$label = $service->getLabel([
    'id' => 1
]);

Get information about an artist:

<?php

$artist = $service->getArtist([
    'id' => 1
]);

Get information about a release:

<?php

$release = $service->getRelease([
    'id' => 1
]);

echo $release['title']."\n";

Get information about a master release:

<?php

$master  = $service->getMaster([
    'id' => 1
]);

echo $master['title']."\n";

Get image

Discogs returns the full url to images so just use the internal client to get those:

php

$release = $client->getRelease([
    'id' => 1
]);
foreach ($release['images'] as $image) {
    $response = $client->getHttpClient()->get($image['uri']);
    // response code
    echo $response->getStatusCode();
    // image blob itself
    echo $client->getHttpClient()->get($image['uri'])->getBody()->getContents();
}

User Collection

Authorization is required when folder_id is not 0.

Get collection folders

<?php

$folders = $service->getCollectionFolders([
    'username' => 'example'
]);

Get collection folder

<?php

$folder = $service->getCollectionFolder([
    'username' => 'example',
    'folder_id' => 1
]);

Get collection items by folder

<?php

$items = $service->getCollectionItemsByFolder([
    'username' => 'example',
    'folder_id' => 3
]);
