web3.eth.compile.solidity
调用web3.eth.compile.solidity()
方法编译采用solidity编写
的智能合约源代码。
调用方法:
web3.eth.compile.solidity(sourceString [, callback])
参数:
sourceString
:String ,solidity合约源代码callback
:Function,可选的回调函数,当指定此参数时将采用异步http请求节点旳API
返回值
Object
- 编译结果对象
示例代码:
var source = "" +
"contract test {\n" +
" function multiply(uint a) returns(uint d) {\n" +
" return a * 7;\n" +
" }\n" +
"}\n";
var compiled = web3.eth.compile.solidity(source);
console.log(compiled);
