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);
