Thereisan"undocumented"methodeth_getRawTransactionByHashfromJSON-RPC

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):Promise
增加TransactionRaw定义
exportdeclareinterfaceTransactionRaw{
raw:string
}
2.项目node_modules下找到web3-eth中 index.js
methods={}
增加方法
newMethod({
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
/**
*Formatstheoutputofatransactionrawvalue
*
*@methodoutputTransactionRawFormatter
*@param{Object}tx
*@returns{Object}
*/
varoutputTransactionRawFormatter=function(tx){
returntx;
};
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
};
