使用 的 Amazon Bedrock 代理程式程式碼範例 AWS SDKs
下列程式碼範例示範如何使用 Amazon Bedrock Agents 搭配 AWS 軟體開發套件 (SDK)。
Actions 是大型程式的程式碼摘錄，必須在內容中執行。雖然動作會告訴您如何呼叫個別服務函數，但您可以在其相關情境中查看內容中的動作。
案例是向您展示如何呼叫服務中的多個函數或與其他 AWS 服務組合來完成特定任務的程式碼範例。
如需開發人員指南和程式碼範例的完整清單 AWS SDK，請參閱搭配 使用 Amazon Bedrock AWS SDK。本主題也包含入門的相關資訊，以及先前SDK版本的詳細資訊。
開始使用
下列程式碼範例說明如何開始使用 Amazon Bedrock Agents。
- JavaScript
-
- SDK for JavaScript (v3)
-
import { fileURLToPath } from "node:url";
import {
BedrockAgentClient,
GetAgentCommand,
paginateListAgents,
} from "@aws-sdk/client-bedrock-agent";
/**
* @typedef {Object} AgentSummary
*/
/**
* A simple scenario to demonstrate basic setup and interaction with the Bedrock Agents Client.
*
* This function first initializes the Amazon Bedrock Agents client for a specific region.
* It then retrieves a list of existing agents using the streamlined paginator approach.
* For each agent found, it retrieves detailed information using a command object.
*
* Demonstrates:
* - Use of the Bedrock Agents client to initialize and communicate with the AWS service.
* - Listing resources in a paginated response pattern.
* - Accessing an individual resource using a command object.
*
* @returns {Promise<void>} A promise that resolves when the function has completed execution.
