会生成两类文件，*.abi *.bin

vote.sol 里面包含了 library和多个contract 类，我这里吧AidocVote.abi、AidocVote.bin 上链

编辑AidocVote.abi文件

address是智能合约地址，transactionHash交易hans,发现address是undefined，没关系我们来排查下

cumulativeGasUsed和gasUsed明显已经消耗完我们 AidocVote.bin 中 contract.new()交易的gas的设置，应该加大gas的消耗

web3.eth.getTransactionReceipt
web3.eth.getTransactionReceipt()方法返回指定交易的收据对象。 如果交易处于pending状态，则返回null。

调用：

web3.eth.getTransactionReceipt(hash [, callback])
参数：

hash：String - 交易的哈希值
callback：Function - 可选的回调函数，其第一个参数为错误对象，第二个参数为结果
返回值：

一个Promise对象，其解析值为交易的收据对象或者null。收据对象具有如下字段：

status - Boolean: 成功的交易返回true，如果EVM回滚了该交易则返回false
blockHash 32 Bytes - String: 交易所在块的哈希值
blockNumber - Number: 交易所在块的编号
transactionHash 32 Bytes - String: 交易的哈希值
transactionIndex - Number: 交易在块中的索引位置
from - String: 交易发送方的地址
to - String: 交易接收方的地址，对于创建合约的交易，该值为null
contractAddress - String: 对于创建合约的交易，该值为创建的合约地址，否则为null
cumulativeGasUsed - Number: 该交易执行时所在块的gas累计总用量
gasUsed- Number: 该交易的gas总量
logs - Array: 该交易产生的日志对象数组

我们将 AidocVote.bin 中的gas改成 2000000
