Solana RPC 方法的常见 JSON 数据结构

各种 Solana RPC 方法将返回更复杂的响应作为结构化 JSON 对象，并填充特定的键值。
这些 JSON 数据结构中最常见的包括：

交易

交易与其他区块链上的交易截然不同。请务必查看交易剖析以了解 Solana 上的交易。

JSON

交易的JSON结构定义如下：

"transaction": {
  "message": {
    "accountKeys": [
      "EF3cbGuhJus5mCdGZkVz7GQce7QHbswBhZu6fmK9zkCR",
      "4LAyP5B5jNyNm7Ar2dG8sNipEiwTMEyCHd1iCHhhXYkY",
      "11111111111111111111111111111111"
    ],
    "header": {
      "numReadonlySignedAccounts": 0,
      "numReadonlyUnsignedAccounts": 1,
      "numRequiredSignatures": 1
    },
    "instructions": [
      {
        "accounts": [
          0,
          1
        ],
        "data": "3Bxs411Dtc7pkFQj",
        "programIdIndex": 2,
        "stackHeight": null
      }
    ],
    "recentBlockhash": "6pw7JBwq9tb5GHiBQgVY6RAp5otbouwYvEc1kbbxKFec"
  },
  "signatures": [
    "2M8mvwhtxyz3vAokXESVeR9FQ4t9QQxF5ek6ENNBBHVkW5XyZvJVK5MQej5ccwTZH6iWBJJoZ2CcizBs89pvpPBh"
  ]
}

JSON 解析

交易的 JSON 解析结构遵循与常规 JSON 格式类似的结构，并附加了帐户和指令信息的解析：

"transaction": {
  "message": {
    "accountKeys": [
      {
        "pubkey": "EF3cbGuhJus5mCdGZkVz7GQce7QHbswBhZu6fmK9zkCR",
        "signer": true,
        "source": "transaction",
        "writable": true
      },
      {
        "pubkey": "4LAyP5B5jNyNm7Ar2dG8sNipEiwTMEyCHd1iCHhhXYkY",
        "signer": false,
        "source": "transaction",
        "writable": true
      },
      {
        "pubkey": "11111111111111111111111111111111",
        "signer": false,
        "source": "transaction",
        "writable": false
      }
    ],
    "instructions": [
      {
        "parsed": {
          "info": {
            "destination": "4LAyP5B5jNyNm7Ar2dG8sNipEiwTMEyCHd1iCHhhXYkY",
            "lamports": 100000000,
            "source": "EF3cbGuhJus5mCdGZkVz7GQce7QHbswBhZu6fmK9zkCR"
          },
          "type": "transfer"
        },
        "program": "system",
        "programId": "11111111111111111111111111111111",
        "stackHeight": null
      }
    ],
    "recentBlockhash": "6pw7JBwq9tb5GHiBQgVY6RAp5otbouwYvEc1kbbxKFec"
  },
  "signatures": [
    "2M8mvwhtxyz3vAokXESVeR9FQ4t9QQxF5ek6ENNBBHVkW5XyZvJVK5MQej5ccwTZH6iWBJJoZ2CcizBs89pvpPBh"
  ]
}

交易状态元数据

{
  "meta": {
    "err": null,
    "fee": 5000,
    "innerInstructions": [],
    "logMessages": [],
    "postBalances": [499998932500, 26858640, 1, 1, 1],
    "postTokenBalances": [],
    "preBalances": [499998937500, 26858640, 1, 1, 1],
    "preTokenBalances": [],
    "rewards": null,
    "status": {
      "Ok": null
    }
  }
}

内部指示

Solana 运行时记录在交易处理期间调用的跨程序指令，并使这些指令可用，从而提高每个交易指令在链上执行内容的透明度。调用的指令按原始交易指令分组，并按处理顺序列出。

内部指令的 JSON 结构定义为以下结构的对象列表

"innerInstructions": [
  {
    "index": 0,
    "instructions": [
      {
        "accounts": [
          0,
          1,
          2
        ],
        "data": "WPNHsFPyEMr",
        "programIdIndex": 3,
        "stackHeight": 2
      },
      {
        "accounts": [
          0,
          1
        ],
        "data": "11111dBUPbGETd4QtNMQVg8HqgcZtKy6DcJm6R4TZufJkuhkDS47VsauCCGhLf2xrm5BQ",
        "programIdIndex": 2,
        "stackHeight": 3
      }
    ]
  }
]
