【中文标题】使用 web3 v1.0 发送原始交易的无效类型错误

【英文标题】：Invalid Type error sending raw transaction using web3 v1.0

【发布时间】：2019-12-05 07:59:22

【问题描述】：

我尝试通过 Infura 网关向 Ropsten 发送原始交易，我收到了错误消息“`Invalid Type”。

这是我的开发环境。

“ethereumjs-tx”：“^1.3.7” “web3”：“^1.0.0-beta.55”

代码如下：

var count = web3.eth.getTransactionCount(fromAddress, 'pending').then(nonce => 
      console.log('This is the nouce'+ nonce)
      var data = MyContract.methods.transfer(toAddress, 10000, from: fromAddress);
      var gasPrice = web3.eth.gasPrice;
      var gasLimit = 90000;

      var rawTransaction = 
        "from": fromAddress,
        "nonce": web3.utils.toHex(nonce),
        "gasPrice": web3.utils.toHex(gasPrice),
        "gasLimit": web3.utils.toHex(gasLimit),
        "to": toAddress,
        "value": 0,
        "data": data,
        "chainId": 0x03
      ;

        var privKey = new Buffer('0x...', 'hex');
        var tx = new TX(rawTransaction);

        tx.sign(privKey);
        var serializedTx = tx.serialize();

      web3.eth.sendRawTransaction('0x' + serializedTx.toString('hex'), function(err, hash) 


        if (!err)
            console.log(hash);
        else
            console.log(err);
      );
      console.log(nonce)
    )

新的错误信息：

【问题讨论】：

你能打印完整的错误吗？

@AnkushRasgon - 我已经更新并分享了上面的完整错误消息

【参考方案1】：

web3 1.x 新版本 试试这个

 to: Contract._address,
  data: Contract.methods.transfer(to, 1000).encodeABI(), 

【讨论】：

@AnkushRasgon- 我试过了。现在，我收到一条新的错误消息。请看上面

改变这个值：'0x0'

okk wait 整体代码okk 有小错误需要时间去解决

我已经想通了。（也许），我应该将这行代码改为这个 MyContract.methods.transfer(toAddress, 10000)..encodeABI()。删除了 from:fromAddress。但是，我弹出了新错误，它说“web3.eth.sendRawTransaction 不是函数”。也许，web3 1.0 不再支持方法了？
