【问题描述】：

您好，我想使用 ankr api 和 web3 提供程序将 bep20 令牌从一个地址转移到另一个地址，但出现类似错误

发件人无效

这是我用于传输代币的代码，我已经将chaind id用于binanace，例如bnb，bsc binance智能链主网

let tokenAddress = '0x41XXXXXXXXXXXXXXXXXXXXXXXXXXXXXbce' //  contract address
 
  let toAddress = req.params.toaddress // where to send it
  let fromAddress = req.params.fromaddress // your wallet
  let pKey = req.params.privatekey.split('0x');
  let privateKey = Buffer.from(pKey[1],'hex');
  
  let contractABI = [
    // transfer
    
      'constant': false,
      'inputs': [
        
          'name': '_to',
          'type': 'address'
        ,
        
          'name': '_value',
          'type': 'uint256'
        
      ],
      'name': 'transfer',
      'outputs': [
        
          'name': '',
          'type': 'bool'
        
      ],
      'type': 'function'
    
  ]

  let contract = new web32.eth.Contract(contractABI, tokenAddress, from: fromAddress)

  // 1e18 === 1 HST
  let amount1 = req.params.amount;

  let amount = web32.utils.toBN(amount1*1000000000000000000)
  // console.log(amount);
  web32.eth.getTransactionCount(fromAddress)
    .then((count) => 
      let rawTransaction = 
        'from': fromAddress,
        'gasPrice': web32.utils.toHex(20 * 1e9),
        'gasLimit': web32.utils.toHex(210000),
        'to': tokenAddress,
        'value': 0x0,
        'data': contract.methods.transfer(toAddress, amount).encodeABI(),
        'nonce': web32.utils.toHex(count),
        "chainId": 56
      
      let transaction = new EthereumTx(rawTransaction,chain:'bsc')
      transaction.sign(privateKey)
      web32.eth.sendSignedTransaction('0x' + transaction.serialize().toString('hex'),(err,hash) => 
        console.log(err)
        var url = "https://etherscan.io/tx/"+hash
        res.json(hash: hash, status_url: url,success:'true',message : 'Transaction has been pushed.');
      )
        
    )

【参考方案1】：

transaction.sign(privateKey)
web32.eth.sendSignedTransaction('0x' + transaction.serialize().toString('hex'),(err,hash) => 

您正在传递未签名的交易，需要传递已签名的交易。

const signedTx = transaction.sign(privateKey)
web32.eth.sendSignedTransaction('0x' + signedTx.serialize().toString('hex'),(err,hash) => 

查看readme中的示例（查找const signedTx sn-p）
