Amazon EventBridge中默认事件总线分发至目标的Contact Events Schema是哪种？

实际分发至EventBridge目标的是**Wrapped（封装式）**格式。

EventBridge的事件有统一的顶层结构规范，必须包含version、id、detail-type、source等核心字段，Wrapped格式完全匹配这一标准，具体的联系事件数据会嵌套在detail字段中。而Unwrapped（非封装式）格式仅仅是Wrapped格式里detail字段的内容，不会作为完整事件直接分发。

Wrapped 格式示例 #

            "enqueueTimestamp": "2021-08-04T17:29:04.000Z"
        },
        "AgentInfo": {

        "CustomerVoiceActivity": {
           "greetingStartTimestamp":"2021-08-04T17:29:20.000Z",
           "greetingEndTimestamp":"2021-08-04T17:29:22.000Z"
        }
    }
}
