web3.js增加eth.getRawTransactionByHash(txhash)方法步骤
eth_getRawTransactionByHash
https://ethereum.stackexchange.com/questions/7473/get-raw-transaction-from-hash
There is an "undocumented" method eth_getRawTransactionByHash from JSON-RPC
curl -H "Content-Type: application/json" -X POST --data \
'{"jsonrpc":"2.0","method":"eth_getRawTransactionByHash","params":[""],"id":1}' http://localhost:8545
1.项目node_modules 下找到web3 下types.d.ts文件
Eth
类中增加方法
getRawTransaction(hash: string, cb?: Callback<TransactionRaw>): Promise<TransactionRaw>
增加TransactionRaw定义
export declare interface TransactionRaw {
raw: string
}
2.项目node_modules 下找到 web3-eth中 index.js
methods={}
增加方法
new Method({
name: 'getRawTransaction',
call: 'eth_getRawTransactionByHash',
params: 1,
inputFormatter: [null],
outputFormatter: formatter.outputTransactionRawFormatter
}),
3.项目node_modules 下找到 web3-core-helpers中 formatters.js
增加 outputTransactionRawFormatter并module.exports中也增加对应
/**
* Formats the output of a transaction raw value
*
* @method outputTransactionRawFormatter
* @param {Object} tx
* @returns {Object}
*/
var outputTransactionRawFormatter = function (tx){
return tx;
};
module.exports = {
inputDefaultBlockNumberFormatter: inputDefaultBlockNumberFormatter,
inputBlockNumberFormatter: inputBlockNumberFormatter,
inputCallFormatter: inputCallFormatter,
inputTransactionFormatter: inputTransactionFormatter,
inputAddressFormatter: inputAddressFormatter,
inputPostFormatter: inputPostFormatter,
inputLogFormatter: inputLogFormatter,
inputSignFormatter: inputSignFormatter,
outputBigNumberFormatter: outputBigNumberFormatter,
outputTransactionFormatter: outputTransactionFormatter,
outputTransactionRawFormatter: outputTransactionRawFormatter,
outputTransactionReceiptFormatter: outputTransactionReceiptFormatter,
outputBlockFormatter: outputBlockFormatter,
outputLogFormatter: outputLogFormatter,
outputPostFormatter: outputPostFormatter,
outputSyncingFormatter: outputSyncingFormatter
};
备注：以上代码是1.0.版本的
一下是0.2
/node_modules/web3/lib/web3/methods/eth.js
var getRawTransaction = new Method({
name: 'getRawTransaction',
call: 'eth_getRawTransactionByHash',
params: 1,
outputFormatter: formatters.outputTransactionRawFormatter
});
return [
getBalance,
……………………………………………………………………………………………………
getWork,
getRawTransaction
];
node_modules/web3/lib/web3/formatters.js
/**
* Formats the output of a transaction raw value
*
* @method outputTransactionRawFormatter
* @param {Object} tx
* @returns {Object}
*/
var outputTransactionRawFormatter = function (tx){
return tx;
};
module.exports = {
inputDefaultBlockNumberFormatter: inputDefaultBlockNumberFormatter,
…………………………………………………………………………………………………………………………………………
outputSyncingFormatter: outputSyncingFormatter,
outputTransactionRawFormatter:outputTransactionRawFormatter
};
备注：可以直接用partiy搭建节点，内部web3直接返回raw
