NAVERクラウドプラットフォームCDN+ Purge API スタートガイド

概要

このガイドには、簡単なシナリオに従ってCDN+インスタンスを照会し、そしてPurgeを遂行します。
詳しい文書は、NAVERクラウドプラットフォームCDN+ Purge API referenceをご参照ください。

シナリオ実行

CDNインスタンス別にドメインリスト照会

CDN インスタンスドメインリスト照会APIを利用して、cdnInstanceIDとDomainID、cdn設定情報を確認します。

アクション
- getCdnPlusInstanceList
アクションパラメータ
- cdnInstanceNo : インスタンス番号(選択)

旧バージョン(12月Deprecated)

OAuth外部ライブラリを利用して、authorizationヘッダにauthparamsを含めて簡単にリクエストできます。

新バージョン

新しいAPI は、認証関連ヘッダを追加する過程を経てAPI を呼び出すことになります。認証関連Signatureを作る方式はv1、v2二つの方式があります。

v1 Signature

    public static String makeSignatureV1(String url, String apiKey, String accessKey, String secretKey, String timestamp, String method) throws Exception{
        String space = " ";
        String newLine = "\n";

        String message = new StringBuilder()
                .append(method)
                .append(space)
                .append(url)
                .append(newLine)
                .append(timestamp)
                .append(newLine)
                .append(apiKey)
                .append(newLine)
                .append(accessKey)
                .toString();

        SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes("UTF-8"), "HmacSHA256");
        Mac mac = Mac.getInstance("HmacSHA256");
        mac.init(signingKey);

        byte[] rawHmac = mac.doFinal(message.getBytes("UTF-8"));
        String encodeBase64String = Base64.encodeBase64String(rawHmac);

        return encodeBase64String;

    }

v2 Signature

    public static String makeSignatureV2(String url, String accessKey, String secretKey, String timestamp, String method) throws Exception{
        String space = " ";
        String newLine = "\n";

        String message = new StringBuilder()
                .append(method)
                .append(space)
                .append(url)
                .append(newLine)
                .append(timestamp)
                .append(newLine)
                .append(accessKey)
                .toString();

        SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes("UTF-8"), "HmacSHA256");
        Mac mac = Mac.getInstance("HmacSHA256");
        mac.init(signingKey);

        byte[] rawHmac = mac.doFinal(message.getBytes("UTF-8"));
        String encodeBase64String = Base64.encodeBase64String(rawHmac);

        return encodeBase64String;

    }

url : Action 実行 URL (Query Stringを含む)
apiKey : API GateWay Access Key
accessKey :ユーザーAccess Key
secretKey : ユーザーSecret Key
timestamp : Epoch時間 (Milli秒)
method : HTTP Request メソッド

詳しい事項はNcloud APIs共通ガイドをご参照ください。

CDN Purge 수행

CDN 특정 도메인에 대하여 Purge를 수행합니다.

アクション
- requestCdnPlusPurge
アクションパラメータ
- cdnInstanceNo : インスタンス番号
- isWholePurge : false (個別ファイルPurge実行)
- isWholeDomain
- true : ドメインが1つのインスタンスで、全体ドメイン対象、顧客保有Nのサービスドメイン+Cache Key Hostnameが'ORIGIN_HOSTNAME'に使用=>全体ドメイン対象Purge実行
- false : 顧客保有Nのサービスドメイン+Cache Key Hostnameが'REQUEST_HOST_HEADER'に使用=>ドメイン個別Purge実行
- targetFileList.1 : /sample_img.jpg (Purge対象ファイル経路とファイル名)
