Question

我正在创建这个非常简单的程序，它将ETH从一个地址发送到另一个地址。我正在使用 rinkeby.infura.io 获得免费的以太网并用于测试目的。

我的代码似乎运行正常，因为当我在 http://localhost:8545 上的testrpc中测试它并使用虚拟帐户地址时，一切正常。但是，当我更改为真实帐户地址并将HttpProvider更改为 https://rinkeby.infura.io/ 时，我收到以下错误：

错误：无效的JSON RPC响应：＆＃34;＆＃34; at Object.InvalidResponse（D：\ Documents \ Projects \ Eth \ node_modules \ web3 \ lib \ web3 \ errors.js：38：16）在HttpProvider.send（D：\ Documents \ Projects \ Eth \ node_modules \ web3 \ lib \ web3 \ httpprovider.js：91：22）在RequestManager.send（D：\ Documents \ Projects \ Eth \ node_modules \ web3 \ lib \ web3 \ requestmanager.js:58:32）在Eth.send [as sendTransaction]（D：\ Documents \ Projects \ Eth \ node_modules \ web3 \ lib \ web3 \ method.js：145：58）在sendBalance（D：\ Documents \ Projects \ Eth \ routes \ index.js：57：11）在D：\ Documents \ Projects \ Eth \ routes \ index.js：80：12 在Layer.handle [as handle_request]（D：\ Documents \ Projects \ Eth \ node_modules \ express \ lib \ router \ layer.js：95：5）在下一个（D：\ Documents \ Projects \ Eth \ node_modules \ express \ lib \ router \ route.js：137：13）在Route.dispatch（D：\ Documents \ Projects \ Eth \ node_modules \ express \ lib \ router \ route.js：112：3）在Layer.handle [as handle_request]（D：\ Documents \ Projects \ Eth \ node_modules \ express \ lib \ router \ layer.js：95：5）

我注意到我忘记在代码 web3.eth.sendTransaction（{}）的部分包含一个回调函数，因此我将其更改为 web3.eth.sendTransaction （{}，function（err，hash）{}）。它删除了无效的JSON RPC错误消息，但它根本不执行整个 sendTransaction（） ，因为我可以看到余额未受影响。

以下是使用rinkeby.infura.io和回调函数的输出：

供您参考，以下是我的代码的两个版本：（1）带有 sendTransaction（） 的回调函数，（2）没有回调函数< / p>

（1）使用回调功能

var express = require('express');
var router = express.Router();

var util = require('ethereumjs-util');
var tx = require('ethereumjs-tx');
try {
    var lightwallet = require('eth-lightwallet');
} catch (err) {
delete global._bitcore
    var lightwallet = require('eth-lightwallet');
}
var txutils = lightwallet.txutils;

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/'));

function balance(addr) {
    var start = Date.now();
    var latestBalance = web3.eth.getBalance(addr, "latest");
    var nonce = web3.eth.getTransactionCount(addr, "latest");
    var end = Date.now();
    return nonce;
}

function showBalance(addr) {
    var start = Date.now();
    var latestBalance = web3.eth.getBalance(addr, "latest");
    var nonce = web3.eth.getTransactionCount(addr, "latest");
    var end = Date.now();
    var res = {
        "address": addr,
        "balance": latestBalance + " Wei / " + web3.fromWei(latestBalance).toString() + " ETH",
        "nonce": nonce.toString(),
        "timestamp": (end - start).toString() + "ms"
    }
    return res;
}

function sendBalance(_from, _to) {
    var nonce = balance(_from);
    var amount = 0.05;
    var rawTx = {
        nonce: web3.toHex(nonce),
        gasPrice: web3.toHex(10),
        gasLimit: web3.toHex(21000),
        to: _to,
        value: web3.toHex(amount * 1000000000),
        data: "",
        chainId: 1
    }

    var addFromPrivateKey = new Buffer('4ce80ef53f9c13e5d68737ff078e0660e803f87735fab9c79bf408335be8963d', 'hex');
    var transaction = new tx(rawTx);
    transaction.sign(addFromPrivateKey);
    var res ="";
    var serializedTx = transaction.serialize().toString('hex');
    web3.eth.sendTransaction({ 
        from: _from, 
        to: _to,
        value: web3.toWei(amount, "ether"),
        gas: rawTx.gasLimit,
        price: rawTx.gasPrice,
        nonce: rawTx.nonce
    }, function(error, hash){res = error;});
    var txLog = "";
    // web3.eth.sendRawTransaction('0x' + serializedTx, function(err, result) {
    //  if(err) {
    //      txLog = err;
    //  } else {
    //      txLog = result;
    //  }
    // });
    res = "Status: " + res + " |||| from: " + _from + "\nsendValueETH: " + amount + "\nrawTx: " + JSON.stringify(rawTx, null, 4) + " " + txLog; 
    return res;
}

// Get Homepage
router.get('/', function(req, res) {

    var dti = sendBalance('0xa5d1274a05ab92e3830d81e0e4302498ccb5b22f', '0x6a1366a19b6dbb4d9fe4781f38538e9dc2ec0698');
    dto = showBalance('0xa5d1274a05ab92e3830d81e0e4302498ccb5b22f');
    dtt = showBalance('0x6a1366a19b6dbb4d9fe4781f38538e9dc2ec0698');

    data = {
        "dta": {
            "sender": dto,
            "recipient": dtt,
            "transaction": dti
        }
    }
    res.render('index', {data});
});


module.exports = router;

（2）没有回叫功能

var express = require('express');
var router = express.Router();

var util = require('ethereumjs-util');
var tx = require('ethereumjs-tx');
try {
    var lightwallet = require('eth-lightwallet');
} catch (err) {
delete global._bitcore
    var lightwallet = require('eth-lightwallet');
}
var txutils = lightwallet.txutils;

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/'));

function balance(addr) {
    var start = Date.now();
    var latestBalance = web3.eth.getBalance(addr, "latest");
    var nonce = web3.eth.getTransactionCount(addr, "latest");
    var end = Date.now();
    return nonce;
}

function showBalance(addr) {
    var start = Date.now();
    var latestBalance = web3.eth.getBalance(addr, "latest");
    var nonce = web3.eth.getTransactionCount(addr, "latest");
    var end = Date.now();
    var res = {
        "address": addr,
        "balance": latestBalance + " Wei / " + web3.fromWei(latestBalance).toString() + " ETH",
        "nonce": nonce.toString(),
        "timestamp": (end - start).toString() + "ms"
    }
    return res;
}

function sendBalance(_from, _to) {
    var nonce = balance(_from);
    var amount = 0.05;
    var rawTx = {
        nonce: web3.toHex(nonce),
        gasPrice: web3.toHex(10),
        gasLimit: web3.toHex(21000),
        to: _to,
        value: web3.toHex(amount * 1000000000),
        data: "",
        chainId: 1
    }

    var addFromPrivateKey = new Buffer('4ce80ef53f9c13e5d68737ff078e0660e803f87735fab9c79bf408335be8963d', 'hex');
    var transaction = new tx(rawTx);
    transaction.sign(addFromPrivateKey);
    var res ="";
    var serializedTx = transaction.serialize().toString('hex');
    web3.eth.sendTransaction({ 
        from: _from, 
        to: _to,
        value: web3.toWei(amount, "ether"),
        gas: rawTx.gasLimit,
        price: rawTx.gasPrice,
        nonce: rawTx.nonce
    });
    var txLog = "";
    // web3.eth.sendRawTransaction('0x' + serializedTx, function(err, result) {
    //  if(err) {
    //      txLog = err;
    //  } else {
    //      txLog = result;
    //  }
    // });
    res = "Status: " + res + " |||| from: " + _from + "\nsendValueETH: " + amount + "\nrawTx: " + JSON.stringify(rawTx, null, 4) + " " + txLog; 
    return res;
}

    dtt = showBalance('0x6a1366a19b6dbb4d9fe4781f38538e9dc2ec0698');

    data = {
        "dta": {

        }
    }
    res.render('index', {data});
});


module.exports = router;

P.S。值得一提的是，这些是样本私钥，地址仅用于演示目的。而且，您可以忽略有关rawTx的任何事情：）

以下是使用testrpc的示例成功输出：

同样，它适用于testrpc，但不适用于rinkeby.infura。我认为它绝对不会对真正的以太坊网络起作用。我是以太坊和区块链开发的新手。任何帮助，即我的问题的解决方案，对我的代码的建议，我将非常感谢它们！提前谢谢！

无法使web3.eth.sendTransaction（）正常工作。该功能无法触发
