發送簽名交易

我想對部署在 rinkeby 測試網上的合約呼叫一個操作。但是交易確認似乎需要很長時間，我在 rinkeby etherscan 上找不到它。我的程式碼有問題嗎？

let Web3= require('web3');
let web3 = new Web3 (new Web3.providers.HttpProvider("http://127.0.0.1:8545"));
var Tx = require('ethereumjs-tx');

tokenAbi =

const tokenAddress = '0xAfff042F602762B59442660aCDF34fdE8681D016';
var Contract = new web3.eth.Contract(tokenAbi, tokenAddress, {from: '0x6C7bc8e30cAE5409b30c16eFA458eADAaE6e6810'});
const tokenReceiver = '0x426e238593d7969f1beb174287a367dd9f41362F';
const tokenAmount = '100000000000000000000';
const PK = 'cdfa2d70c2f309106665188dc69996e3150983737b4b0882b768b11221d8a603'

const trxData = Contract.methods.transfer(tokenReceiver, tokenAmount).encodeABI();

web3.eth.getTransactionCount('0x6C7bc8e30cAE5409b30c16eFA458eADAaE6e6810').then(function(nonce){

 var rawTx = {
 to: '0xafff042f602762b59442660acdf34fde8681d016',
 data: trxData,
 gasPrice: 1000000000,
 gasLimit: 7000000,
 nonce: nonce,
 chainId: 4
}

var tx = new Tx(rawTx);
const privateKey = Buffer.from(PK, 'hex')
tx.sign(privateKey);

var serializedTx = tx.serialize();

web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'))
.on('receipt', console.log);

})

gasPrice太低了，試試：2000000000 (2Gwei)太低gasLimit了，甚至低於一個交易的底價，試著增加它（記住未使用的gas會退還給你）

每次交易後都應該更新隨機數，使用：

web3.eth.getTransactionCount(address [, defaultBlock] [, callback])

希望這可以幫助。

很可能，100 的 gs 限制太低了。交易可能不會被提取以包含在待處理的塊中。

嘗試增加氣體限制。
