eth_getCode

返回给定块高的区块中存储在给定地址的合约代码。

参数

• quantity | TAG : 区块的块高，或字符串 "latest" 、 "earliest" 或 "pending"

params: [
    '0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b',
    'latest'
]

返回值

• data : 指定地址处的合约代码

示例代码

• 请求：

curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"eth_getCode","params":["0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b","0xb"],"id":1}' "http://127.0.0.1:6791"

• 响应：

{
    "jsonrpc":"2.0",
    "id":1,
    "result":"0x开头的合约代码数据"
}

eth_getStorageAt

返回指定块高的区块中指定地址存储的key对应的value。

参数

• data : 20字节，存储地址

• string : key

• quantity | TAG : 区块的块高，或字符串 "latest" 、 "earliest" 或 "pending"

返回值

• data : 指定区块中指定地址所存储的指定key对应的值

示例代码

根据要提取的存储计算正确的位置。考虑下面的合约，由0x391694e7e0b0cce554cb130d723a9d27458f9298 部署在地址 0x295a70b2de5e3953354a6a8344e616ed314d7251 ：

contract Storage {
    uint pos0;
    mapping(address => uint) pos1;

    function Storage() {
        pos0 = 1234;
        pos1[msg.sender] = 5678;
    }
}

提取pos0的值很直接：

curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"eth_getStorageAt","params":["0x295a70b2de5e3953354a6a8344e616ed314d7251","0x0", "latest"],"id":1}' "http://127.0.0.1:6791"

响应结果：

{
    "jsonrpc":"2.0",
    "id":1,
    "result":"0x00000000000000000000000000000000000000000000000000000000000004d2"
}

要提取映射表中的成员就难一些了。映射表中成员位置的计算如下：

keccack(LeftPad32(key, 0), LeftPad32(map position, 0))

这意味着为了提取 pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] 的值，我们需要如下计算：

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"))

venachain console控制台自带的web3库可以用来进行这个计算：

> var key = "000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298" + "0000000000000000000000000000000000000000000000000000000000000001"
undefined
> web3.sha3(key, {"encoding": "hex"})
"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

现在可以提取指定位置的值了：

curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"eth_getStorageAt","params":["0x295a70b2de5e3953354a6a8344e616ed314d7251","0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"],"id":1}' "http://127.0.0.1:6791"

相应结果如下：

{
    "jsonrpc":"2.0",
    "id":1,
    "result":"0x000000000000000000000000000000000000000000000000000000000000162e"
}

eth_call

立刻执行一个新的消息调用，无需在区块链上创建交易。

参数

• object : 交易调用对象

  • from data : 20 Bytes，发送交易的原地址，可选

  • to data : 20 Bytes，交易目标地址

  • gas quantity : 交易可用gas量，可选。eth_call不消耗gas，但是某些执行环节需要这个参数

  • gasPrice quantity : gas价格，可选

  • value quantity : 交易发送的以太数量，可选

  • data data : 方法签名和编码参数的哈希，可选

• quantity : 区块的块高，或字符串 "latest", "earliest" 或 "pending"

返回值

• data : 所执行合约的返回值

示例代码

• 请求：

curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"eth_call","params":[{"from":"0x054c138b7ed3083ee9a36e1b09542fccdc155d75","to":"0x0000000000000000000000000000000000000011","gas":"0x106000","gasPrice":"0x0","value":"0x1","data":""},"0x8"],"id":1}' "http://127.0.0.1:6791"

• 响应：

{
    "jsonrpc":"2.0",
    "id":1,
    "result":"0x00000003"
}

eth_estimateGas

执行并估算一个交易需要的gas用量。该次交易不会写入区块链。

注解

由于多种原因，例如EVM的机制及节点的性能，估算的数值可能比实际用量大的多。

参数

• object : 交易调用对象

  • from data : 20 Bytes，发送交易的原地址，可选

  • to data : 20 Bytes，交易目标地址，可选

  • gas quantity : 交易可用gas量，可选。eth_call不消耗gas，但是某些执行环节需要这个参数

  • gasPrice quantity : gas价格，可选

  • value quantity : 交易发送的以太数量，可选

  • data data : 方法签名和编码参数的哈希，可选

所有的属性都是可选的。如果没有指定gas用量上限，venachain将使用挂起块的gas上限。在这种情况下，返回的gas估算量可能不足以执行实际的交易。

返回值

• quantity : gas用量估算值

示例代码

• 请求：

curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc":"2.0","method":"eth_estimateGas","params":[{"gas":"0x106000","gasPrice":"0x0","value":"0x1","data":""}],"id":1}' "http://127.0.0.1:6791"

eth_sign

使用如下公式计算 Venachain 签名 sign(keccak256("\x19Venachain Signed Message:\n" + len(message) + message))) 。

通过给消息添加一个前缀，可以让结果签名被识别为 Venachain 签名。这可以组织恶意DApp签名任意数据（例如交易）并使用签名冒充受害者。

注解

进行签名的地址必须是解锁的。

返回值

array : 日志对象数组，如果没有新生成的日志，则返回空数组。

1. 使用 eth_newBlockFilter 创建的过滤器将返回块哈希（32字节），例如 ["0x3454645634534..."] 。

2. 使用 eth_newPendingTransactionFilter 创建的过滤器将返回交易哈希(32字节)，例如 ["0x6345343454645..."] 。

3. 使用 eth_newFilter 创建的过滤器，日志对象具有如下参数：

   • removed bool : 如果日志已被删除则返回true，如果是有效日志则返回false

   • logIndex quantity : 日志在块内的索引序号。对于挂起日志，该值为null

   • blockNumber quantity : 该日志所在区块的块高。对于挂起日志，该值为null

   • blockHash data : 该日志所在块的哈希。对于挂起日志，该值为null

   • transactionHash data : 创建该日志的交易的哈希。对于挂起日志，该值为null

   • transactionIndex quantity : 创建日志的交易索引序号，对于挂起日志，该值为null

   • address data : 该日志的源地址

   • data data : 包含该日志的一个或多个32字节无索引参数

   • topics data array : 0~4个32字节索引日志参数的数据。在solidity中，第一个主题是事件签名，例如 Deposit(address,bytes32,uint256) ，除非你声明的是匿名事件
