獲取令牌
如果您只想生成用於測試API請求的訪問令牌，則可以使用此令牌 示例應用.
令牌是從Brightcove獲得的 OAuth API。 在獲取訪問令牌之前，首先需要獲取特定於要訪問的API和操作的客戶端憑據（客戶端ID和客戶端密鑰）。 要獲取您的客戶憑證，請參閱 管理API憑證.
獲得憑據後，您可以通過以下方式獲取訪問令牌： POST 請求：
https://oauth.brightcove.com/v4/access_token
您必須通過此調用傳遞以下標頭：
Content-Type: application/x-www-form-urlencodedAuthorization: Basic {client_id}:{client_secret}
整個 {client_id}:{client_secret} 字符串必須經過Base64編碼（如果您將字符串傳遞為，curl會自動對字符串進行Base64編碼 --user 證書; 在其他語言中，您需要自己處理Base64編碼）。
您還必鬚髮送以下鍵/值對作為請求正文或URL參數：
grant_type=client_credentials
響應將如下所示（為便於閱讀，此處打印得很漂亮）：
{
"access_token": "ANB7xKhiUZmwltVd3f1odcHHM9VAwg02kwmLwtZwHv3SxGCOWLUf5W4G7X22PRjmR9StvFUqzpVZ1suOfyfOigdi-rnohxyEaSSuZceeLw_9OBW7fXldOG05HEgkeK3N-DBZZZyilodmjA1JWZHbgI3IU7Rmz5IPGyi-sDxHN3KlOr1BDZlLZpXPdFPwEyb6idq-z8AL-blKTSMtNI3_fz3oNBisfrHGUv5tXHoQT4B7FYcvdrap16gTOO7_wNt1zmgLJiUHvyxZgsgBchm_AhohVL-AYgcfCbCR0v7d2hgI4ag35pnZNeujDiBLfnCFcVMlqQGq8UEVZrmU9a8y4pVAGih_EImmghqmSrkxLPYZ800-vIWX-lw",
"token_type": "Bearer",
"expires_in": 300
}
access_token 價值是您必須傳遞的 Authorization 標頭以及以下形式的API調用：
Authorization: Bearer {access_token}
expires_in value是訪問令牌有效的秒數。
實施策略
如果您的應用僅會零星地調用Brightcove API，則您最好忽略 expires_in 參數，並為每個調用獲取一個新的訪問令牌。 在這種情況下，處理順序將如下所示：
另一方面，如果您知道您的應用程序將頻繁頻繁地連續多次調用API（例如，生成長報告），那麼僅在需要訪問令牌時才更有效地獲取訪問令牌。 有兩種基本方法可以做到這一點：
- 繼續嘗試API調用，如果看到
UNAUTHORIZED錯誤響應中，請獲取一個新令牌並再次進行API調用。 在這種情況下，處理順序將如下所示：
通過檢查呼叫失敗獲取令牌 - 另一種方法是添加
expires_in每次獲取令牌時，將值設置為當前時間（以紀元秒為單位），然後在以後的API調用中，對照當前時間檢查過期時間，以查看是否需要獲取新令牌。 在這種情況下，您的處理順序將如下所示：
使用過期檢查獲取令牌
郵差和失眠
可以針對REST API設置一些有用的測試工具，以與Brightcove OAuth系統配合使用以獲取訪問令牌。 我們提供了一些指南，其中包括針對兩個最受歡迎的跨平台工具執行此操作的步驟：
代碼樣例
以下是一些代碼示例，可幫助您入門。
Shell腳本示例
第一個示例是一個Shell腳本，它實現了上面的第一個實現邏輯：它從用戶那裡獲取輸入，總是獲取一個新的令牌，然後進行API調用。 該腳本可在任何Brightcove API上運行，並且在構建應用程序時可能會發現它對於測試API調用很有用。
Shell腳本代碼

normal=`tput sgr0`

echo 'Enter the full API call:'
read API_CALL
echo Your API call: $API_CALL

echo "Enter the HTTP method: [ ${bold}g${normal} (GET - default) | ${bold}po${normal} (POST) | ${bold}pa${normal} (PATCH) | ${bold}pu${normal} (PUT) | ${bold}d${normal} (DELETE) ]:"

then

Ruby示例
下一個示例是Ruby腳本，該腳本也採用了第一種實現邏輯：始終獲取令牌，然後進行API調用。 此示例調用了 Analytics API，但可以修改為與任何API配合使用。
Ruby代碼
#!/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示例
此示例是一個Python腳本，用於實現上述第3種實現邏輯。 它試圖使 Analytics API 呼叫，但是如果呼叫因未授權錯誤而失敗，它將獲取一個新的訪問令牌並重試該呼叫。
此腳本還從外部文件讀取客戶端憑據-憑據數據文件顯示在Python代碼下方。
