# 使用会话属性的请求示例
<a name="bedrock-agent-intent-sample"></a>

以下示例说明如何调用 AMAZON。 BedrockAgentIntent 并演示了在响应中填充的会话和请求属性。这些属性包含 Bedrock 代理的响应数据，并可用于访问此代理的输出、Amazon Bedrock 知识库来源和操作组调用详细信息。

```
{
    "sessionId": "user-session-123",
    "messages": [{
        "content": "Your order #12345 is currently being processed and will ship within 2-3 business days. You will receive a tracking number via email once it ships.",
        "contentType": "PlainText"
    }],
    "sessionState": {
        "sessionAttributes": {
            "x-amz-lex:bedrock-agent-search-response": "Your order #12345 is currently being processed and will ship within 2-3 business days. You will receive a tracking number via email once it ships.",
            "x-amz-lex:bedrock-knowledge-base-search-response-source": "[{\"title\": \"Order Processing Guide\", \"uri\": \"s3://knowledge-base/orders/processing.pdf\", \"excerpt\": \"Standard orders typically ship within 2-3 business days...\"}]",
            "x-amz-lex:bedrock-agent-action-group-invocation-input": "{\"actionGroupName\": \"OrderLookup\", \"function\": \"getOrderStatus\", \"parameters\": {\"orderId\": \"12345\", \"customerId\": \"67890\"}}",
            "x-amz-lex:bedrock-agent-knowledge-base-lookup-input": "{\"knowledgeBaseId\": \"KB123456\", \"query\": \"order status processing time\", \"numberOfResults\": 3}"
        },
        "intent": {
            "name": "BedrockAgentIntent",
            "slots": {},
            "state": "Fulfilled",
            "confirmationState": "None"
        },
        "dialogAction": {
            "type": "ElicitIntent"
        }
    },
    "interpretations": [{
        "intent": {
            "name": "FallbackIntent",
            "slots": {}
        },
        "interpretationSource": "Lex"
    }],
    "requestAttributes": {
        "x-amz-lex:channels:platform": "Web",
        "x-amz-lex:accept-content-types": "PlainText",
        "x-amz-lex:bedrock-agent-search-response": "Your order #12345 is currently being processed and will ship within 2-3 business days. You will receive a tracking number via email once it ships.",
        "x-amz-lex:bedrock-knowledge-base-search-response-source": "[{\"title\": \"Order Processing Guide\", \"uri\": \"s3://knowledge-base/orders/processing.pdf\", \"excerpt\": \"Standard orders typically ship within 2-3 business days...\"}]",
        "x-amz-lex:bedrock-agent-action-group-invocation-input": "{\"actionGroupName\": \"OrderLookup\", \"function\": \"getOrderStatus\", \"parameters\": {\"orderId\": \"12345\", \"customerId\": \"67890\"}}",
        "x-amz-lex:bedrock-agent-knowledge-base-lookup-input": "{\"knowledgeBaseId\": \"KB123456\", \"query\": \"order status processing time\", \"numberOfResults\": 3}"
    }
}
```

在此示例中，会话属性显示了如何 BedrockAgentIntent 填充响应数据，包括代理的答案、使用的 Amazon Bedrock 知识库来源、操作组调用以及用于生成响应的 Amazon Bedrock 知识库查询详细信息。
