システムステータス
トークンの取得
APIリクエストをテストするためのアクセストークンを生成するだけの場合は、これを使用できますサンプルアプリ。
トークンはBrightcoveOAuthAPIから取得されます。アクセストークンを取得する前に、まず、アクセスするAPIと操作に固有のクライアント資格情報（クライアントIDとクライアントシークレット）を取得する必要があります。クライアントの資格情報を取得するには、を参照してください。 API資格情報の管理。
資格情報を取得したら、次のようにしてアクセストークンを取得します。POSTリクエスト先：
https://oauth.brightcove.com/v4/access_token
この呼び出しでは、次のヘッダーを渡す必要があります。
Content-Type: application/x-www-form-urlencodedAuthorization: Basic {client_id}:{client_secret}
全体{client_id}:{client_secret}文字列はBase64でエンコードされている必要があります（文字列を次のように渡すと、curlは自動的にBase64でエンコードします--user資格情報;他の言語では、Base64エンコーディングを自分で処理する必要があります）。
また、次のキー/値のペアをリクエスト本文または URL パラメータとして送信する必要があります。
grant_type=client_credentials
応答は次のようになります（ここでは読みやすくするためにプリティ印刷されています）。
{
"access_token": "ANB7xKhiUZmwltVd3f1odcHHM9VAwg02kwmLwtZwHv3SxGCOWLUf5W4G7X22PRjmR9StvFUqzpVZ1suOfyfOigdi-rnohxyEaSSuZceeLw_9OBW7fXldOG05HEgkeK3N-DBZZZyilodmjA1JWZHbgI3IU7Rmz5IPGyi-sDxHN3KlOr1BDZlLZpXPdFPwEyb6idq-z8AL-blKTSMtNI3_fz3oNBisfrHGUv5tXHoQT4B7FYcvdrap16gTOO7_wNt1zmgLJiUHvyxZgsgBchm_AhohVL-AYgcfCbCR0v7d2hgI4ag35pnZNeujDiBLfnCFcVMlqQGq8UEVZrmU9a8y4pVAGih_EImmghqmSrkxLPYZ800-vIWX-lw",
"token_type": "Bearer",
"expires_in": 300
}
access_token値は、次の形式で API Authorization呼び出しでヘッダーに渡す必要があるものです。
Authorization: Bearer {access_token}
ザ・expires_in valueは、アクセストークンが有効な秒数です。
実装戦略
アプリがBrightcoveAPIに対して散発的な呼び出しのみを行う場合は、無視することをお勧めします。expires_inパラメータを設定し、呼び出しごとに新しいアクセストークンをフェッチするだけです。その場合、処理シーケンスは次のようになります。
一方、アプリが頻繁に多数のAPI呼び出しをすばやく連続して行うことがわかっている場合（たとえば、長いレポートを生成する場合）、必要な場合にのみアクセストークンをフェッチする方が効率的です。これを行うには、2つの基本的な方法があります。
- 先に進んでAPI呼び出しを試してみてください。
UNAUTHORIZEDエラーが発生した場合は、新しいトークンをフェッチして、API呼び出しを再度行ってください。この場合、処理シーケンスは次のようになります。
コール失敗のチェックでトークンを取得する - 別のアプローチは、を追加することです
expires_inトークンをフェッチするたびにエポック秒単位で現在の時刻に値を設定し、その後のAPI呼び出しで、有効期限を現在の時刻と照合して、新しいトークンをフェッチする必要があるかどうかを確認します。この場合、処理シーケンスは次のようになります。
有効期限の確認でトークンを取得する
郵便配達員と不眠症
Brightcove OAuthシステムと連携してアクセストークンを取得するように、RESTAPIのいくつかの便利なテストツールを設定できます。最も人気のある2つのクロスプラットフォームツールでこれを行うための手順を含むガイドがあります。
コードサンプル
始めるのに役立ついくつかのコードサンプルを次に示します。
シェルスクリプトの例
最初の例は、上記の最初の実装ロジックを実装するシェルスクリプトです。ユーザーからの入力を受け取り、常に新しいトークンを取得してから、API呼び出しを行います。このスクリプトは、どのBrightcove APIでも機能し、アプリをビルドするときにAPI呼び出しをテストするのに役立つ場合があります。
