視訊雲端 SSAI 廣告標籤驗證

在本主題中，您將學習如何跟踪通過服務器端廣告插入（SSAI）指定的廣告調用。

概覽

為了幫助調試服務器端廣告，帶有SSAI的動態投放提供了API端點來跟踪廣告調用。

要使用存儲在Video Cloud中的視頻內容調試服務器端廣告，請按照以下步驟操作：

查看有關API路徑和授權的常規信息
跟踪廣告配置
檢索跟踪詳細信息

一般資訊

下列資訊適用於所有 SSAI API 要求。

基本網址

SSAI API 的基本網址為：

  https://ssai.api.brightcove.com/v1

帳號路徑

在所有情況下，我們都會針對特定的視訊雲端帳戶提出要求。因此，您將始終將該術語accounts後跟您的帳戶 ID 添加到基本 URL 中：

  https://ssai.api.brightcove.com/v1/accounts/your account id

授權

API請求需要一個Authorization標頭：

  Authorization: Bearer your access token

這access_token是一個臨時的 OAuth2 訪問令牌，必須從布萊特灣 OAuth 服務獲得。如需有關如何取得用戶端認證並使用它們來擷取存取權杖的詳細資訊，請參閱 Brightcove OAuth 概觀。

作業

當您要求用戶端認證時，您必須指定您想要的帳戶存取或作業類型。以下是 SSAI API 目前支援的作業清單：

SSAI 資料：
video-cloud/ssai/read
video-cloud/ssai/all

跟踪廣告配置

要跟踪廣告配置，請按照以下步驟操作：

收集信息

收集以下信息身體您的API請求：

參數	類型	描述
`account_id`	字串	用戶帳號
`playback_config`	物件	字段在配置字段詳細信息 SSAI API文檔中的部分。
`title_metadata`	物件	告訴系統您的內容多長時間才能生成正確的廣告響應。例如，以下內容告訴系統內容為1分鐘長。用於插入相應的廣告。 `"title_metadata": { "duration": "1m" }`
`videocloud_metadata`	物件	可選。僅當您使用引用元數據字段的模板變量時才需要。這些定義在廣告變數 SSAI API文檔中的部分。

請求

為SSAI廣告配置創建跟踪。

檢索跟踪詳細信息

如上一節所述運行廣告跟踪後，您可以使用會話ID檢索有關跟踪的詳細信息。

的session_id指定緩存會話。每個會話基於視頻內容長度都有自己的長度。您可以在上一步中從API調用的響應中獲取ID。

會話ID可以在上一節的VMAP響應中找到。這是一個例子：

  <bc:BrightcoveDebug sessionID="your session id"></bc:BrightcoveDebug>

請求

要通過提供會話ID來檢索廣告呼叫跟踪信息，請使用類似於以下內容的GET請求：
