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":["<TX_HASH>"],"id":1}' http://localhost:8545<TX_HASH> - transaction id

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

Eth

   類中增加方法

 getRawTransaction(hash: string, cb?: Callback<TransactionRaw>): Promise<TransactionRaw>

增加TransactionRaw定義

export declare interface TransactionRaw { raw: string}

2.項目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.項目node_modules 下找到 web3-core-helpers中  formatters.js

增加 outputTransactionRawFormatter并module.exports中也增加對應

/** * 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};

備注：以上代碼是1.0.版本的
