POST 和 PATCH 有效负载

有关/deployments端点的 POST 有效负载示例，请参阅下文，这将创建一个新的用例。

 }
 }

}

对于更新，结构与上面相同，但有一些注意事项：

共享用例 APIs

以下 REST API 端点可用于文本代理和 Bedrock Agent 用例：

用例详情 API

details API 端点检索有关特定用例的信息：

GET /details/{useCaseConfigKey}

此端点返回特定用例的配置详细信息，包括模型参数、知识库设置和其他部署信息。它需要经过 Amazon Cognito 身份验证的 JWT 令牌才能进行授权。

文本用例

发送消息有效负载

如果您直接与 /sendMessage API 集成，则必须遵守以下请求和响应负载格式。

请求有效负载

{
 "action": "sendMessage",
 "question": "the message to send to the api",
 "conversationId": "", // If not provided, a new conversation will be created, with the conversationId returned in the response. All subsequent messages in that conversation (where history is retained), should provide the conversationId there.
 "promptTemplate": "", // Optional. Overrides the configured prompt
 "authToken": "XXXX" // Optional. accessToken from cognito flow. Required for RAG with RBAC
}

响应负载

问题回答

对于每个查询， WebSocket API 将使用 1 个（如果禁用了流式传输）或许多（如果启用了流式传输）JSON 对象进行响应，其结构如下。

{
 "data": "some data",
 "conversationId": "id",
}

源文件回复

如果您已将 RAG 用例配置为返回源文档，那么对于用于创建响应的每个源文档，您还将在每个响应的末尾收到以下有效负载。

{
 "sourceDocument": {
 "excerpt": "some excerpt from the",
 "location": "s3://fake-bucket/test.txt",
 "score": 0.500,
 "document_title": null,
 "document_id": null,
 "additional_attributes": null
 },
 "conversationId": "some-id"
}

反馈 API 有效负载

以下是/feedback/{useCaseId}端点的 POST 负载示例，它将针对特定用例提交用户反馈：

{
  "useCaseRecordKey": "12345678-12345678",
  "conversationId": "12345678-1234-1234-1234-123456789012",
  "messageId": "12345678-1234-1234-1234-123456789012",
  "feedback": "positive",
  "feedbackReason": ["accurate", "helpful"],
  "comment": "This response was very helpful.",
  "rephrasedQuery": "What are the key features of Amazon Bedrock?",
  "sourceDocuments": [
    "s3://bucket-name/document1.pdf",
    "s3://bucket-name/document2.pdf"
  ]
}

基岩代理用例

InvokeAgent 负载

如果您要直接与集成/invokeAgent API，则必须遵守以下请求和响应负载格式。

请求负载

{
"action": "invokeAgent",
"inputText": "User query to the agent",
"conversationId": "", // Optional. Empty conversationId implies a new conversation. When not provided, a new conversationId will be created and returned with the response. All subsequent messages in the same conversation should provide the same conversationId (i.e. chat memory/history is maintained).
"authToken": "XXXX" // Optional. accessToken from cognito flow. If provided, it needs to be a valid JWT token associated with the user
}

响应有效载荷

问题回答

对于每个查询， WebSocket API 将使用一个（如果禁用了流式传输）或多个（如果启用了流式传输）JSON 对象进行响应，其结构如下。

{
 "data" "some data",
 "conversationId": "id",
 }
