curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_getRawTransactionByHash","params":["<TX_HASH>"],"id":1}' http://localhost:8545
<TX_HASH> - transaction id

 getRawTransaction(hash: string, cb"htmlcode">

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
};
