若是你但願立刻開始學習以太坊DApp開發,能夠訪問匯智網提供的出色的在線互動教程:git
發送一個已經簽名的交易。好比能夠用下述簽名的例子。github
若是交易是一個合約建立,請使用web3.eth.getTransactionReceipt()在交易完成後獲取合約的地址。web
調用:異步
web3.eth.sendRawTransaction(signedTransactionData [, callback])
參數:函數
signedTransacionData
: String - 16進制格式的簽名交易數據。callback
: Function - 回調函數,用於支持異步的方式執行7。返回值:學習
String
- 32字節的16進制格式的交易哈希串。示例:ui
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" });
