システムステータストークンの取得
API リクエストのテスト用にアクセストークンを生成するだけの場合は、こちらを使用できます: サンプルアプリケーション.
トークンは Brightcove OAuth API から取得されます。アクセストークンを取得するには、まずはあなたがアクセスしたい API と操作に固有のクライアントクレデンシャル（クライアントID とクライアントの秘密）を取得する必要があります。クライアントクレデンシャルを取得するには、次の記事を参照してください: API クレデンシャルの管理.
クレデンシャルを取得したら、次のような POST リクエストを実行してあなたのアカウント内のプレイリストの数を取得することもできます:
https://oauth.brightcove.com/v4/access_token
このコールでは、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}
{client_id}:{client_secret} の文字列全体は Base64 でエンコードされている必要があります（curl により自動的に Base64 でエンコードされます、もし次の形式で渡すならば --user クレデンシャル; 他の言語ではあなた自身が Base64 エンコーディング処理をする必要があります）。
また、次のキーと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
レスポンスは次のようになります（読みやすいように以下に記載します）：
{
"access_token": "ANB7xKhiUZmwltVd3f1odcHHM9VAwg02kwmLwtZwHv3SxGCOWLUf5W4G7X22PRjmR9StvFUqzpVZ1suOfyfOigdi-rnohxyEaSSuZceeLw_9OBW7fXldOG05HEgkeK3N-DBZZZyilodmjA1JWZHbgI3IU7Rmz5IPGyi-sDxHN3KlOr1BDZlLZpXPdFPwEyb6idq-z8AL-blKTSMtNI3_fz3oNBisfrHGUv5tXHoQT4B7FYcvdrap16gTOO7_wNt1zmgLJiUHvyxZgsgBchm_AhohVL-AYgcfCbCR0v7d2hgI4ag35pnZNeujDiBLfnCFcVMlqQGq8UEVZrmU9a8y4pVAGih_EImmghqmSrkxLPYZ800-vIWX-lw",
"token_type": "Bearer",
"expires_in": 300
}
挽き目 access_token の値は、以下の形式のように API 呼び出しと一緒に Authorization ヘッダーで渡す必要があります。
Authorization: Bearer {access_token}
挽き目 expires_in の値は、アクセストークンが有効な秒数です。
導入計画
あなたのアプリが Brightcove API への散発的な呼び出しを行うだけであれば、 expires_in パラメータを無視して、すべての呼び出しに対して新しいアクセストークンを取得することもできます。その場合、処理順序は次のようになります。
一方で、アプリケーションが頻繁に多くの API コールを連続して実行することがわかっている場合（長いレポートを生成するために）、必要なときにのみアクセストークンを取得する方が効率的です。こちらを行うには次の二つの基本的な方法があります:
- API コールを試しレスポンスに
UNAUTHORIZEDエラーが発生する場合は、新しいトークンを取得して API コールを再度実行してください。この場合、処理順序は次のようになります。
コールが失敗したことを確認してトークンを取得する - もう一つの方法は、トークンを取得するたびに
expires_in値を現在の時刻に Epoch 秒単位で追加し、その後の API コールでは、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するために期限が切れた時間と現在の時刻を調べます。この場合、処理順序は次のようになります:
有効期限をチェックしてトークンを取得する
Postman と Insomnia
アクセストークンを取得するために、REST API のいくつかの有用なテストツールを Brightcove OAuth システムと連携して設定できます。こちらを行うため手順として最も一般的な二つのクロスプラットフォームツールがこちらです:
コードサンプル
こちらが使い始めに役に立ついくつかのコードサンプルです。
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: ユーザーからのインプットを受け取り、常に新しいトークンを取得し、API コールを行います。こちらのスクリプトはどの Brightcove API でも動作しますし、アプリをビルドする際の API コールのテストに便利です。

Ruby の例

Ruby コード
#!/usr/bin/env ruby
# view id --> content,
#!/usr/bin/env ruby
require 'rest-client'
require 'json'
client_id = '5eb0f20e-29a8-4f19-8cb5-80336e2789ab'
client_secret = 'Zqpb_2YrvnGUEjqQUndx6GsjQ3JyAgXoA2gNbhoj-yUV4scij0jwCN0OBz9FILEwHupjeqwdbOUSFMi7zkhpVg'
response = RestClient.post 'https://oauth.brightcove.com/v4/access_token', :client_id=>client_id,:client_secret=>client_secret,:grant_type=>'client_credentials'
token = JSON.parse(response)["access_token"]
puts "The extracted token is:" + token + "\n\n\n"
data = RestClient.get 'https://data.brightcove.com/analytics-api/videocloud/account/1234567890001/report?dimensions=video&from=2014-01-01&to=2014-03-30', { 'Authorization' => "Bearer #{token}", 'Accept' => 'application/json' }
puts "This is the result from the query: \n" + data
Python の例
こちらのサンプルは Python スクリプトで、上記の三番目の実装ロジックを実装します。こちらは Analytics API コールを試行しますが、UNAUTHORIZED エラーでコールが失敗した場合は、新しいアクセストークンを取得してコールを再試行します。
こちらのスクリプトは外部ファイルからクライアントクレデンシャルも読み取ります - クレデンシャルデータファイルは Python コードの下に表示されます。

# server to server communication to obtain an access token.
