基本操作

查看块高度

执行命令：

$ cita-cli rpc blockNumber

命令返回：

{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x283"
}

其中 result 表示本次查询时的块高度为 0x283。 CITA 默认 3s 出一个块，重复执行查询命令，可以观察到 result 在持续的增长。

部署合约

执行命令：

cita-cli rpc sendRawTransaction \
    --code 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 \

该命令将合约的字节码部署到区块链上。

命令返回：

{
  "id": 4,
  "jsonrpc": "2.0",
  "result": {
    "hash": "0xec4b93bab3c815950f7342781c735895a4c9dcbf50a4e9f4d28204253560f3f4",
    "status": "OK"
  }
}

查看回执

执行命令：

cita-cli rpc getTransactionReceipt --hash 0xec4b93bab3c815950f7342781c735895a4c9dcbf50a4e9f4d28204253560f3f4

其中的 hash 为部署合约的交易 hash，所查询的结果为部署合约的交易回执。

命令返回：

其中 content 为交易数据。由于数据经过了签名处理，所以与部署合约时指定的 --code 不一致。可以使用 cita-cli 提供的 decode-unverifiedTransaction 命令来解码。

执行命令：

cita-cli tx decode-unverifiedTransaction --content 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

其中的 data 数据便与部署合约中指定的 code 相一致。

调用合约

执行命令，调用 set 函数：

cita-cli rpc sendRawTransaction \
    --code 0x60fe47b10000000000000000000000000000000000000000000000000000000000000001 \

    --address 0xb701924639d802dc8093d1a43dffa9939a4506de

注意：这里的 address 要与部署合约回执中的 contractAddress 相一致。

命令返回：

{
  "id": 4,
  "jsonrpc": "2.0",
  "result": {
    "hash": "0xfa3673433191e7daa190601318295e53a92aa62b15573b8a4a439e7ee58be55e",
    "status": "OK"
  }
}

停止节点

以节点 0 为例，执行命令：

$ bin/cita stop test-chain/0
stop...ok

其他操作

更多其他操作使用以下命令查看帮助信息：

$ bin/cita help

详细说明请查看 CITA 命令说明。

Notice

  • 请不要先进到 bin 目录，再执行以上的部署操作，错误示范：

    shell $ cd bin $ cita setup test-chain/0

  • 请勿在一台服务器上运行多个容器。因为虽然 CITA 在 Docker 中运行，但是容器并没有做网络隔离。

  • 请不要同时在 host 系统里面运行 CITA 以及相关的 RabbitMQ 等软件，以免造成端口冲突。
