AgentCore 게이트웨이의 리소스 템플릿 나열
AgentCore 게이트웨이가 제공하는 사용 가능한 모든 리소스 템플릿을 나열하려면 게이트웨이의 MCP 엔드포인트에 POST 요청을 하고 요청 본문에서를 메resources/templates/list서드로 지정합니다.
POST /mcp HTTP/1.1
Host: ${GatewayEndpoint}
Content-Type: application/json
Authorization: ${Authorization header}
${RequestBody}
다음 값을 교체합니다.
응답은 URI 템플릿, 이름, 설명 및 MIME 유형과 함께 사용 가능한 리소스 템플릿 목록을 반환합니다.
리소스 템플릿은 RFC 6570 URI 템플릿을 사용하여 파라미터화된 리소스를 설명합니다. 클라이언트는 템플릿 파라미터를 입력하여에 사용할 구체적인 리소스 URIs 구성할 수 있습니다resources/read. 예를 들어 템플릿을 로 확장할 users://{user_id}/profile 수 있습니다users://123/profile.
리소스 템플릿 나열을 위한 코드 샘플
게이트웨이에서 사용 가능한 리소스 템플릿을 나열하는 예를 보려면 다음 방법 중 하나를 선택합니다.
