There is an "undocumented" method eth_getRawTransactionByHash from JSON-RPC

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

1.项目node_modules 下找到web3 下types.d.ts文件

Eth

类中增加方法

rush:js;"> getRawTransaction(hash: string,cb?: Callback): Promise

增加TransactionRaw定义

rush:js;"> export declare interface TransactionRaw { raw: string }

2.项目node_modules 下找到 web3-eth中 index.js

rush:js;"> methods={}

增加方法

rush:js;"> 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

rush: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,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
