RPC API를 사용하면 노드 및 밸리데이터에 대한 상태 정보를 쿼리할 수 있습니다.

노드 상태​

주어진 노드의 일반 상태(동기화 상태, nearcore 노드 버전, 프로토콜 버전 등)와 현재 밸리데이터 집합을 반환합니다.

무엇이 잘못될 수 있나요?​

API 요청이 실패하면 RPC 서버는 제한된 수의 잘 정의된 오류 변형과 함께 구조화된 오류 응답을 반환하므로, 클라이언트 코드는 가능한 모든 오류 사례를 철저하게 처리할 수 있습니다. JSON-RPC 오류는 오류 응답을 구조화하기 위해 verror 규칙을 따릅니다.

검증 상태​

Queries active validators on the network returning details and the state of validation on the blockchain.

  • 메서드: validators
  • params: ["block hash"], [block number], {"epoch_id": "epoch id"}, {"block_id": block number}, {"block_id": "block hash"}, or [null] for the latest block

Note: If you want the latest block hash, block number and epoch id, you will need to query from the last block in an epoch. You can also query validators endpoint for past epochs if you input block hash, block number or epoch id of the past epoch that you want.

Example:

input: [block number]

{
  "jsonrpc": "2.0",
  "id": "dontcare",
  "method": "validators",
  "params": [17791098]
}

무엇이 잘못될 수 있나요?​

API 요청이 실패하면 RPC 서버는 제한된 수의 잘 정의된 오류 변형과 함께 구조화된 오류 응답을 반환하므로, 클라이언트 코드는 가능한 모든 오류 사례를 철저하게 처리할 수 있습니다. JSON-RPC 오류는 오류 응답을 구조화하기 위해 verror 규칙을 따릅니다.

{
    "error": {
        "name": <ERROR_TYPE>,
        "cause": {
            "info": {..},

주의

위 구조의 code, data, 및 message 필드는 레거시 항목으로 간주되며, 향후 사용되지 않을 수 있습니다. 이에 의존하지 마세요.

다음은 validators 메서드에 의해 반환될 수 있는 오류 변형의 전체 목록입니다.
