Block命令介绍

DNA区块链客户端 dnaNode-CLI 提供了信息获取模块，可以在命令行中通过 info 命令进行以下操作：

  • 查询交易信息
  • 查询交易状态
  • 查询区块信息
  • 查询区块高度

此外，你可以通过 help 命令获取模块的帮助信息 。

dnaNode info help

1. 交易信息

要根据交易哈希查询交易信息，使用 tx 命令。

你可以在第一个终端启动单机测试模式。

dnaNode --testmode

然后在第二个终端中查询测试网中的交易信息。

请求正文如下：

$ dnaNode info tx 1ebde66ec3f309dad20a63f8929a779162a067c36ce7b00ffbe8f4cfc8050d79
{
   "Version": 0,
   "Nonce": 0,
   "GasPrice": 0,
   "GasLimit": 18446744073709551615,
   "Payer": "AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM",
   "TxType": 209,
   "Payload": {
      "Code": "1c010114c27820271114214d747b0b577daf32a19911dcb90400ca9a3b04696e69741400000000000000000000000000000000000000010068164f6e746f6c6f67792e4e61746976652e496e766f6b65"
   },
   "Attributes": [],
   "Sigs": [],
   "Hash": "1ebde66ec3f309dad20a63f8929a779162a067c36ce7b00ffbe8f4cfc8050d79",
   "Height": 0
}

在返回的交易状态中，各字段的含义如下：

  • GasLimit：交易对应的智能合约执行步数。
  • Payer：交易签名的账户。
  • Hash：交易哈希。

2. 交易状态

要根据交易哈希查询交易状态，使用 status 命令。

你可以在第一个终端启动DNA单机测试模式。

dnaNode --testmode

然后在第二个终端中查询测试网中的交易状态。

请求正文如下：

$ dnaNode info status 1ebde66ec3f309dad20a63f8929a779162a067c36ce7b00ffbe8f4cfc8050d79
Transaction states:
{
   "TxHash": "1ebde66ec3f309dad20a63f8929a779162a067c36ce7b00ffbe8f4cfc8050d79",
   "State": 1,
   "GasConsumed": 0,
   "Notify": [
      {
         "ContractAddress": "0100000000000000000000000000000000000000",
         "States": [
            "transfer",
            "AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM",
            "AZW8eBkXh5qgRjmeZjqY2KFGLXhKcX4i2Y",
            1000000000
         ]
      }
   ]
}

在返回的交易状态中，各字段的含义如下：

  • State：交易执行结果，若值为 1，表示交易执行成功。
  • Notify ：交易执行时所触发的事件。

3. 区块信息

要根据区块高度或者区块哈希查询区块信息，使用 block 命令。

你可以在第一个终端启动DNA单机测试模式。

dnaNode --testmode

然后在第二个终端中查询测试网中的区块信息。

4. 区块高度

要获取所接入网络的当前区块高度，使用 curblockheight 命令。

你可以在第一个终端启动DNA单机测试模式。

dnaNode --testmode

然后在第二个终端中查询测试网的当前区块高度。

$ dnaNode info curblockheight
CurrentBlockHeight:241331
