getblock 方法

根据指定的索引，返回对应的区块信息。

{
  "jsonrpc": "2.0",
  "method": "getblock",
  "params": [index, verbose],
  "id": 1
}

参数说明

• index：区块索引（区块高度） = 区块数 - 1。

• verbose：可选参数，verbose 默认值为 0，

  • verbose 为 0 时返回的是区块的序列化后的信息，用 16 进制字符串表示，如果从中获取详细信息需要调用 SDK 来进行反序列化。
  • verbose 为 1 时返回的是对应区块的详细信息，用 Json 格式字符串表示。
