[ニフティクラウド]mobile backendのAPIをPHPで実装

More than 1 year has passed since last update.

仕様書

http://mb.cloud.nifty.com/doc/current/rest/common/format.html

いろいろあって、バックエンド側でAPIを取得する機会があったので
実装したときのメモとして。。。

完成品

phpのcrulにて実装

環境

PHP 5.x, 7.x
Phalcon 1.x, 2.x, 3.x

const

    /**
     * @var string
     */
    const SIGNATURE_STRING =
        "SignatureMethod=HmacSHA256"
        . "&SignatureVersion=2"
        . "&X-NCMB-Application-Key=%s"
        . "&X-NCMB-Timestamp=%s"
        . "%s";

これは、固定値でいいだろう。

setter getter

    /**
     * @param string $timeStamp
     */
    public function setTimeStamp($timeStamp)
    {
        $this->time_stamp = $timeStamp;
    }

    /**
     * @return string
     */
    public function getTimeStamp()
    {
        return $this->time_stamp;
    }

    /**
     * @param $domain
     */
    public function setDomain($domain)
    {
        $this->domain = $domain;
    }

    /**
     * @return string
     */
    public function getDomain()
    {
        return $this->domain;
    }

    /**
     * @return string
     */
    public function getEndPoint()
    {
        return $this->end_point;
    }

    /**
     * @param string $api_path
     * @return $this
     */
    public function setEndPoint($api_path)
    {
        $this->end_point = $this->getVersion() . $api_path;
        return $this;
    }

    /**
     * @return string
     */
    public function getVersion()
    {
        return $this->version;
    }

    /**
     * @param $version
     */
    public function setVersion($version)
    {
        $this->version = $version;
    }

    /**
     * @return string
     */
    public function getClientKey()
    {
        return $this->client_key;
    }

    /**
     * @param $client_key
     */
    public function setClientKey($client_key)
    {
        $this->client_key = $client_key;
    }

    /**
     * @return string
     */
    public function getApplicationKey()
    {
        return $this->application_key;
    }

    /**
     * @param $application_key
     */
    public function setApplicationKey($application_key)
    {
        $this->application_key = $application_key;
    }

可変しそうなのは別途実装だな。

construct

    /**
     *  __construct
     */
    public function __construct()
    {
        // config
        $config = $this->getDI()->get('config')->get('nifty');

        // Domain
        $this->setDomain($config->get('domain'));

        // Version
        $this->setVersion($config->get('version'));

        // client key
        $this->setClientKey($config->get('client_key'));

        // application key
        $this->setApplicationKey($config->get('application_key'));

        // time stamp
        $this->setTimeStamp(date('c'));

        $this
            // HEADER
            ->addHeader('X-NCMB-Application-Key:'. $this->getApplicationKey())
            ->addHeader('X-NCMB-Timestamp:'. $this->getTimeStamp())
            ->addHeader('Content-Type:application/json')
            // Options
            ->addOptions(CURLOPT_TIMEOUT, 10)
            ->addOptions(CURLOPT_CONNECTTIMEOUT, 5)
            ->addOptions(CURLOPT_RETURNTRANSFER, true);
    }

newのタイミングで固定値はセットしておく。

Signature

    public function addHeaderSignature()
    {
        $signature_string  = '';
        $signature_string .= $this->getMethod() . "\n";
        $signature_string .= $this->getDomain() . "\n";
        $signature_string .= $this->getEndPoint() . "\n";
        $signature_string .= sprintf(
            self::SIGNATURE_STRING,
            $this->getApplicationKey(),
            $this->getTimeStamp(),
            $this->isQuery() ? "&".$this->getQuery() : ""
        );

        $signature = hash_hmac('sha256', $signature_string, $this->getClientKey(), true);
        $signature = base64_encode($signature);

        $this->addHeader('X-NCMB-Signature:'. $signature);

        return $this;
    }

シグネチャー作ってHEADERにセット

YAML

prd:
  nifty:
    domain: mb.api.cloud.nifty.com
    version: /2013-09-01/
    application_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    client_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

使い方

$mobileBackend = new MobileBackend();
$json = $mobileBackend
    ->setMethod("GET")
    ->addQuery("target", [$os])
    ->setEndPoint("push")
    ->execute();

完成品

queryがある時とない時のURLの作り方とシグネチャーの生成で手間取った。
