常见的结构 AWS Lambda 函数用于

在 Lambda 响应中，有许多结构会反复出现。本节提供了有关这些常见结构的详细信息。

意图

"intent": {
    "confirmationState": "Confirmed | Denied | None",
    "name": string,
    "slots": {
        // see 槽值 for details about the structure
    },
    "state": "Failed | Fulfilled | FulfillmentInProgress | InProgress | ReadyForFulfillment | Waiting",
    "kendraResponse": {
        // Only present when intent is KendraSearchIntent. For details, see
// https://docs.aws.amazon.com/kendra/latest/dg/API_Query.html#API_Query_ResponseSyntax       }
}

intent 字段映射到包含以下字段的对象：

槽值

slots 字段存在于 intent 结构中，并映射到一个结构，该结构的键是用于该意图的槽位的名称。如果该槽位不是多值槽位（有关更多详细信息，请参阅 使用一个插槽中的多个值），则会将其映射到具有以下格式的结构。请注意，shape 取值为 Scalar。

{
    slot name: {
        "shape": "Scalar",
        "value": {
            "originalValue": string,
            "interpretedValue": string,
            "resolvedValues": [
                string,
                ...
            ]
        }
    }
}

如果该槽位是多值槽位，则其映射到的对象中包含另一个名为 values 的字段，该字段映射到一个结构列表，其中每个结构都包含有关构成多值槽位的槽位信息。列表中每个对象的格式与常规槽位所映射到的对象的格式相匹配。请注意，shape 的取值为 List，但 values 下面组件槽位的 shape 的取值为 Scalar。

{
    slot name: {
    "shape": "List",
    "value": {
        "originalValue": string,
        "interpretedValue": string,
        "resolvedValues": [
            string,
            ...
        ]
    },
    "values": [
        {
            "shape": "Scalar",
            "value": {
                "originalValue": string,
                "interpretedValue": string,
                "resolvedValues": [
                    string,
                    ...
                ]
            }
        },
        {
            "shape": "Scalar",
            "value": {
                "originalValue": string,
                "interpretedValue": string,
                "resolvedValues": [
                    string,
                    ...
                ]
            }
        },
        ...
    ]
}

槽位对象中的字段如下所述：

{
    "originalValue": string,
    "interpretedValue": string,
    "resolvedValues": [
        string,
        ...
    ]
}

"values": [
    {
        "shape": "Scalar",
        "value": {
            "originalValue": string,
            "interpretedValue": string,
            "resolvedValues": [
                string,
                ...
            ]
        }
    },
    {
        "shape": "Scalar",
        "value": {
            "originalValue": string,
            "interpretedValue": string,
            "resolvedValues": [
                string,
                ...
            ]
        }
    },
    ...
]

会话状态

sessionState 字段映射到一个对象，该对象包含与用户对话的状态相关的信息。该对象中实际显示的字段取决于对话操作的类型。有关 Lambda 响应中的必填字段，请参阅 响应中的必填字段。sessionState 对象的格式如下所示：

"sessionState": {
    "activeContexts": [
        {
            "name": string,
            "contextAttributes": {
                string: string
            },
            "timeToLive": {
                "timeToLiveInSeconds": number,
                "turnsToLive": number
            }
        },
        ...
    ],
    "sessionAttributes": {
        string: string,
        ...
    },
    "runtimeHints": {
        "slotHints": {
            intent name: {
                slot name: {
                    "runtimeHintValues": [
                        {
                            "phrase": string
                        },
                        ...
                    ]
                },
                ...
            },
            ...
        }
    },
    "dialogAction": {
        "slotElicitationStyle": "Default | SpellByLetter | SpellByWord",
        "slotToElicit": string,
        "type": "Close | ConfirmIntent | Delegate | ElicitIntent | ElicitSlot"
    },
    "intent": {
        // see 意图 for details about the structure
    },
    "originatingRequestId": string
}

这些字段如下所述：

{
    "name": string,
    "contextAttributes": {
        string: string
    },
    "timeToLive": {
        "timeToLiveInSeconds": number,
        "turnsToLive": number
    }
}

{
    string: string,
    ...
}

{
    "slotHints": {
        intent name: {
            slot name: {
                "runtimeHintValues": [
                    {
                        "phrase": string
                    },
                    ...
                ]
            },
            ...
        },
        ...
    }
}

{
    "slotElicitationStyle": "Default | SpellByLetter | SpellByWord",
    "slotToElicit": string,
    "type": "Close | ConfirmIntent | Delegate | ElicitIntent | ElicitSlot"
}
