管理 VOD 会话

使用 Video Stitcher API,您每次在将广告动态插播到客户端设备之前,都会创建一个视频点播 (VOD) 会话。创建会话时,响应中会包含播放网址以及您插入视频的广告的相关信息。

本页介绍了如何创建和管理 Google Ad Manager 启用的 VOD 会话。如需详细了解这些类型的 VOD 会话,请参阅管理由 Google Ad Manager 启用的 VOD 会话

准备工作

创建会话

如需为广告插播视频创建会话,请使用 projects.locations.vodSessions.create 方法。

创建 VOD 会话时,必须填写以下字段:

  • adTracking:确定是客户端播放器应触发播放和活动事件,还是 Video Stitcher API 应代表客户端播放器触发播放事件;如需详细了解客户端广告跟踪,请参阅处理 VOD 客户端广告跟踪

    本部分中的示例使用服务器端广告跟踪。

创建 VOD 会话时,以下字段是可选的:

REST

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_NUMBERIAM 设置页面上的项目编号字段中的 Google Cloud 项目编号
  • LOCATION:创建会话的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • us-west1
    • asia-east1
    • asia-south1
    • asia-southeast1
    • europe-west1
    • southamerica-east1
  • VOD_CONFIG_ID:用户定义的视频点播配置标识符

如需发送您的请求,请展开以下选项之一:

您应该收到类似以下内容的 JSON 响应:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID",
  "interstitials": {
    "sessionContent": {
      "duration": "60s"

Video Stitcher API 会为每个请求生成唯一的会话 ID。会话会在 4 小时后过期。

广告必须先编码,然后才能拼接到 VOD 会话中。当您为广告接缝的视频创建会话时,Video Stitcher API 会确定广告是否已从上一个会话编码。如果有,JSON 响应将指明广告插播事件。该 API 仅查找与您的 Google Cloud 项目关联的会话创建的编码广告。如需详细了解此过程,请参阅概览

查看 JSON 响应。此响应表示广告缝合到会话中。如果是这种情况,请等待 5 分钟(用于广告编码),然后重新运行创建会话命令。响应现在应类似于以下内容:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID",
  "interstitials": {
    "adBreaks": [
      {
        "progressEvents": [
          {
            "timeOffset": "0s",
            "events": [
              {
                "type": "IMPRESSION",
                "uri": "https://securepubads.g.doubleclick.net/pcs/view..."
              },
              {

                "uri": "https://pubads.g.doubleclick.net/pagead/interaction/..."
              },
              ...

              },

                "uri": "https://pubads.g.doubleclick.net/pcs/click...",
                "id": "GDFP"
              },

  "assetId": "ASSET_ID",
  "adTracking": "SERVER",
  "vodConfig": "projects/PROJECT_NUMBER/locations/LOCATION/vodConfigs/VOD_CONFIG_ID"
}

响应是一个 VOD 会话对象,其中包含以下字段:

如果您要代表客户的设备生成会话,请使用 HTTP 标头设置以下参数:

参数 HTTP 标头
CLIENT_IP x-user-ip
REFERRER_URL referer
USER_AGENT user-agent

您可以将以下标头添加到上述 curl 请求中:

-H "x-user-ip: CLIENT_IP" \
-H "referer: REFERRER_URL" \
-H "user-agent: USER_AGENT" \

广告代码宏

广告代码可以包含宏,这可能会导致每个会话的广告代码不同。在广告代码中,宏用方括号表示,如以下示例所示:

AD_TAG_URI&macro=[my-key]

adTagUriVOD 配置中定义。

如需替换广告代码宏中的值,请在 adTagMacroMap 字段中提供映射。例如,如果您想将 [my-key] 宏替换为字符串 my-value,则需要提供以下内容:

{
  ...
  "adTagMacroMap": {
    "my-key": "my-value"
  },
  ...
}

当 Video Stitcher API 请求广告元数据时,它会使用以下广告代码:

AD_TAG_URI&macro=my-value

获取会话

如需获取广告插播视频的会话,请使用 projects.locations.vodSessions.get 方法。

REST

处理客户端广告跟踪

启用客户端广告跟踪后,播放器负责触发广告跟踪事件。您可以在创建 VOD 会话时返回的 interstitials 对象中找到客户端跟踪信息。

interstitials 对象包含从广告代码请求解析出的随播广告的广告跟踪信息和元数据。如需检查哪些广告已拼接,请参阅检查 VOD 会话

插页式广告

广告跟踪信息在 interstitials 对象中按广告插播时间点分组。

广告插播时段可能包含进度事件,这些事件会指定已触发的每个事件的事件 URI 和相对于广告插播时段开始时间的时间偏移量。如需详细了解进度事件,请参阅 ProgressEvent 参考文档。

广告插播时间点可能还包含活动事件和随播广告。如需详细了解配套广告,请参阅 CompanionAds 参考文档。

以下是插页式广告示例:

{
  "adBreaks": [
    {
      "progressEvents": [
        {
          "timeOffset": "0s",
          "events": [
            {
              "type": "IMPRESSION",
              "uri": "https://example.com/impression"
            },
            {
              "type": "START",
              "uri": "https://example.com/start"
            }
          ]
        },
        {
          "timeOffset": "1.250s",
          "events": [
            {
              "type": "FIRST_QUARTILE",
              "uri": "https://example.com/firstquartile"
            }
          ]
        }
      ],
      "ads": [
        {
          "duration": "5s",
          "activityEvents": [
            {
              "type": "PAUSE",
              "uri": "https://example.com/pause"
            }
          ],
          "companionAds": {
            "required": "all",
            "companions": [
              {
                "width": 200,
                "height": 100,
                "staticResource": {
                  "uri": "https://example.com/static.png",
                  "creativeType": "image/png"
                }
              }
            ]
          }
        },
        {
          "duration": "10s"
        }
      ],
      "startTimeOffset": "0s",
      "endTimeOffset": "15.000s"
    }
  ],
  "sessionContent": {
      "duration": "120.000s"
  }
}

在上例中,有一个前贴片广告插播时间点,其中有两个广告缝合到一个 VOD 资产中。第 1 个广告的时长为 5 秒,第 2 个广告的时长为 10 秒。拼接视频的总时长为 120 秒,如 sessionContent 中的 duration 字段所示。

客户端收到此对象后,应执行以下操作:

  • 在广告插播时间点开始时向 https://example.com/start 发出请求。
  • 在广告插播开始时向 https://example.com/impression 发出请求。
  • 每当观看者在第一个广告期间暂停视频时,都向 https://example.com/pause 发出请求。
  • 在第一个广告播放 1.25 秒后向 https://example.com/firstQuartile 发出请求。
  • 在第一个广告期间加载随播广告 https://example.com/static.png

检查 VOD 会话

本部分介绍了如何检查给定 VOD 会话的广告代码详情和拼接详情。如需了解详情,请参阅 VodAdTagDetailVodStitchDetail 的 REST 文档。

adTagUri 字段在 VOD 会话的 VOD 配置中定义,用于指定用于检索广告元数据的网址。Video Stitcher API 在发出请求时还会包含用户元数据。

/vodAdTagDetails 端点包含以下信息:

  • 已解析的广告代码
  • 用户元数据
  • 请求正文和标头
  • 响应正文和标头

/vodStitchDetails 端点包含以下信息:

  • 广告插播时间点 ID
  • 广告 ID
  • 广告时间偏移值(以秒为单位)
  • 广告未插入的原因
  • 广告媒体元数据

列出广告代码详情

如需列出 VOD 会话的广告代码详情,请使用 projects.locations.vodSessions.vodAdTagDetails.list 方法。

REST

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_NUMBERIAM 设置页面上的项目编号字段中的 Google Cloud 项目编号
  • LOCATION:会话所在的位置;请使用某个受支持的地区
    显示位置
    • us-central1
    • us-east1
    • us-west1
    • asia-east1
    • asia-south1
    • asia-southeast1
    • europe-west1
    • southamerica-east1
  • SESSION_ID:视频点播会话的会话 ID

如需发送您的请求,请展开以下选项之一:

您应该收到类似以下内容的 JSON 响应:

{
  "vodAdTagDetails" : [
    {
      "name": "projects/PROJECT_NUMBER/locations/LOCATION/vodSessions/SESSION_ID/vodAdTagDetails/VOD_AD_TAG_DETAILS_ID",
