发送一个已经签名的交易。比如可以用下述签名的例子。

如果交易是一个合约创建,请使用web3.eth.getTransactionReceipt()在交易完成后获取合约的地址。

调用:

web3.eth.sendRawTransaction(signedTransactionData [, callback])

 

参数:

  • signedTransacionData: String – 16进制格式的签名交易数据。
  • callback: Function – 回调函数,用于支持异步的方式执行7。

返回值:

  • String – 32字节的16进制格式的交易哈希串。

示例:

var Tx = require('ethereumjs-tx');
var privateKey = new Buffer('e331b6d69882b4cb4ea581d88e0b604039a3de5967688d3dcffdd2270c0fd109', 'hex')

var rawTx = {
  nonce: '0x00',
  gasPrice: '0x09184e72a000', 
  gasLimit: '0x2710',
  to: '0x0000000000000000000000000000000000000000', 
  value: '0x00', 
  data: '0x7f7465737432000000000000000000000000000000000000000000000000000000600057'
}

var tx = new Tx(rawTx);
tx.sign(privateKey);

var serializedTx = tx.serialize();

//console.log(serializedTx.toString('hex'));
//0xf889808609184e72a00082271094000000000000000000000000000000000000000080a47f74657374320000000000000000000000000000000000000000000000000000006000571ca08a8bbf888cfa37bbf0bb965423625641fc956967b81d12e23709cead01446075a01ce999b56a8a88504be365442ea61239198e23d1fce7d00fcfc5cd3b44b7215f

web3.eth.sendRawTransaction(serializedTx.toString('hex'), function(err, hash) {
  if (!err)
    console.log(hash); // "0x7f9fade1c0d57a7af66ab4ead79fade1c0d57a7af66ab4ead7c2c2eb7b11a91385" 
});
