编译合约

这里以Counter合约为例:

$ cat Counter.sol
pragma solidity ^0.4.24;

contract Counter {
    uint public count;

    function add() public {
        count += 1;
    }

    function reset() public {
        count = 0;
    }
}

$ curl -o solc -L https://github.com/ethereum/solidity/releases/download/v0.4.24/solc-static-linux
$ chmod +x solc
$ sudo mv ./solc /usr/local/bin/
$ solc --hashes --bin Counter.sol

======= Counter.sol:Counter =======

创建合约

创建合约的参数是编译合约输出的二进制字节码，注意前面要增加0x前缀。

返回值为这笔创建合约交易的交易哈希。

}

参数为前一步操作返回的交易哈希。

返回值为该笔交易的执行结果信息，其中contract_addr字段为刚才部署的合约的地址。

得到合约地址后，就可以调用其中的方法。

查询合约状态

查询合约中的count值：

$ cldi call -t 0x138e2c0098ab9a5c38a7bc4a16a186f58fc4058a 0x06661abd
result: 0x0000000000000000000000000000000000000000000000000000000000000000

-t参数为合约地址。

第二个参数为要调用的count()方法的函数签名。

返回值为count的当前值。

发送交易

向合约发送交易，调用add方法改变count的值：

$ cldi send -t 0x138e2c0098ab9a5c38a7bc4a16a186f58fc4058a 0x4f2be91f

-t参数为合约地址。

第二个参数为要调用的add()方法的函数签名。

等待交易上链之后，再次查询就可以发现合约状态有了变化：

$ cldi call -t 0x138e2c0098ab9a5c38a7bc4a16a186f58fc4058a 0x06661abd
result: 0x0000000000000000000000000000000000000000000000000000000000000001
