//Contract build .json to js obj
import { abi } from './contract.js'

//Init web3
import { getWeb3 } from  './getWeb3'

// Import are working fine.

export const getTokenContract = () => (
  new Promise((resolve, reject) => {
    getWeb3.then(web3 => { //Get web3
      var contract = web3.eth.contract(abi) //Instance contract with json abi
      var instance = contract.at("0x918daf9d0bd5c927ca8f1c5776e7c0c200be0fc23994dbe34dd9c9669c6a900d") //Get adress of the contract
      console.log(contract)
      resolve(instance)
    })
  })

我尝试访问实例内的智能合约功能。当我 console.log 时，abi 中的功能正确显示。

该地址没有可用的功能。举个例子：

实例.getFidelity...

getFidelity 没有定义，所以崩溃。

  • testrpc 启动。
  • 松露编译
  • 松露迁移（成功部署在 0x918...）
