无法使用 web3.js发送 ERC20 令牌

Question

在我阅读了几篇帖子和指南之后，我一直在努力使用 web3 发送代币交易。我正在使用人类标准令牌 abi 来获得 ERC20 abi。我只是想将 10 ZRX 从我的一个地址转移到另一个地址。

这是失败的函数。

var Tx = require('ethereumjs-tx');
const abi = require('human-standard-token-abi')
import * as Web3 from 'web3';
const fromAddress = '0xB03...'.toLowerCase();
const secondaryAddress = '0xF75...'.toLowerCase();
const zrxAddress = '0xe41d...';
deposit(zrxAddress, secondaryAddress, '10');
function deposit(tokenAddress:string, depositAddress:string, amount:string) {
        var count = web3.eth.getTransactionCount(fromAddress);
        var contract = web3.eth.contract(abi).at(tokenAddress);
        console.log('Contract Address :' + contract.address);
        try {
            var rawTransaction = {
            "from": fromAddress,
            "nonce": web3.toHex(count),
            "gasPrice": "0x04e3b29200",
            "gasLimit": "0x7458",
            "to": contract.address,
            "value": "0x0",
            "data": contract.transfer(depositAddress, size),
            "chainId": "0x01"
        }
        console.log(rawTransaction);
        var privKey = new Buffer(key, 'hex');
        var tx = new Tx(rawTransaction);
        console.log(tx);
        //tx.sign(privKey);
        var serializedTx = tx.serialize();
    } catch (err) {
        console.log('nnfailed to build');
        console.log(err);
    }
    try {
    console.log('nnAttempting to send tx');
    web3.eth.sendTransaction(tx, function(err, hash) {
        if(!err)
            console.log(hash);
        else
            console.log(err);
    });
    } catch (err) {
        console.log('nfailed to send');
        console.log(err);
    }
}

我目前在构建原始事务方面失败。这是错误输出。

它似乎拒绝了我正在输入的地址之一，但我不确定是哪一个。当我注销tokenAddress，contract.address和我的两个地址时，它们都被定义了。但是在 web3 源代码中，我添加了一个 print 语句，以查看它所说的地址无效以及它获得的地址是"未定义"的。

tx 对象中的data部分不正确(可能还有其他问题，但该部分很突出(。您需要为方法调用传入编码字符串。您实际上是在尝试在设置 data 时调用 transfer 方法。

var rawTransaction = {
            "from": fromAddress,
            "nonce": web3.toHex(count),
            "gasPrice": "0x04e3b29200",
            "gasLimit": "0x7458",
            "to": contract.address,
            "value": "0x0",
            "data": contract.transfer.getData(depositAddress, amount),
            "chainId": "0x01"
}

(我也把size改成了amount。不知道size是从哪里来的。
