奇亚(Chia, XCH) 接口之获取主链相关信息(含最新块高)

奇亚(Chia, XCH) 接口之获取主链相关信息,主要是获取当前块高,调用的路径为 /get_blockchain_state

参数则传递空 JSON 即可 {}

例如

curl --insecure --cert ~/.chia/mainnet/config/ssl/full_node/private_full_node.crt --key ~/.chia/mainnet/config/ssl/full_node/private_full_node.key -d '{}' -H "Content-Type: application/json" -X POST https://localhost:8555/get_blockchain_state | python3 -m json.tool

备注,后面的 |python3 -m json.tool 主要是用于美化返回值

返回的结果为

{
    "blockchain_state": {
        "difficulty": 700,
        "genesis_challenge_initialized": true,
        "mempool_size": 7,

            "synced": true
        }
    },
    "success": true
}

里面有几个参数很重要:

  • 一个是返回的是否包含错误,如果 "success" 字段为 true 则结果正确
  • 一个是 blockchain_state/sync/synced 参数,表示当前节点是否已经同步完毕,如果同步完毕则 true
  • 一个是 blockchain_state/peak/header_hash 参数,表示当前最新区块的区块哈希,你可以理解为编号
  • 一个是 blockchain_state/peak/height 参数,表示当前最新的块高

其它参数就看你自己的需要与否了
