Bitcoin getblock用法及代码示例

比特币(Bitcoin) RPC Blockchain API中getblock的用法及代码示例。

用法:

getblock "blockhash" ( verbosity )

如果 verbosity 为0，则返回已序列化的字符串，即块‘hash’的hex-encoded数据。

如果 verbosity 为1，则返回一个对象，其中包含有关块‘hash’的信息。

如果 verbosity 为2，则返回一个对象，其中包含有关块‘hash’的信息以及有关每个事务的信息。

参数1 - blockhash

类型：字符串，必填

区块哈希

参数2 - verbosity

类型：数字，可选，默认值= 1

0表示hex-encoded数据，1表示json对象，2表示带有事务数据的json对象

返回结果(对于 verbosity = 0)

名称	类型	描述
data	string	块‘hash’的已序列化字符串hex-encoded数据。

返回结果(对于 verbosity = 1)

{
  "hash" : "hash",     (string) the block hash (same as provided)
  "confirmations" : n,   (numeric) The number of confirmations, or -1 if the block is not on the main chain
  "size" : n,            (numeric) The block size
  "strippedsize" : n,    (numeric) The block size excluding witness data
  "weight" : n           (numeric) The block weight as defined in BIP 141
  "height" : n,          (numeric) The block height or index
  "version" : n,         (numeric) The block version
  "versionHex" : "00000000", (string) The block version formatted in hexadecimal
  "merkleroot" : "xxxx", (string) The merkle root
  "tx" : [               (array of string) The transaction ids
     "transactionid"     (string) The transaction id
     ,...
  ],
  "time" : ttt,          (numeric) The block time in seconds since epoch (Jan 1 1970 GMT)
  "mediantime" : ttt,    (numeric) The median block time in seconds since epoch (Jan 1 1970 GMT)
  "nonce" : n,           (numeric) The nonce
  "bits" : "1d00ffff", (string) The bits
  "difficulty" : x.xxx,  (numeric) The difficulty
  "chainwork" : "xxxx",  (string) Expected number of hashes required to produce the chain up to this block (in hex)
  "nTx" : n,             (numeric) The number of transactions in the block.
  "previousblockhash" : "hash",  (string) The hash of the previous block
  "nextblockhash" : "hash"       (string) The hash of the next block
}

返回结果(对于 verbosity = 2)

{
  ...,                     Same output as verbosity = 1.
  "tx" : [               (array of Objects) The transactions in the format of the getrawtransaction RPC. Different from verbosity = 1 "tx" result.
         ,...
  ],
  ,...                     Same output as verbosity = 1.
}
