用web3.js发送signTransaction并解决问题

Question

区块链，web3.js杂志

​

我是块链上的新手，尝试使用ropsten测试网络进行交易，但是会出错。

如果有人能帮我的话，先谢谢你。

 exports.sendTransactions = () => {

      var admin = "0xEF9dE245F335e0f3ae8A9563FD54D001de1d3E2D";
      var contract_address = "0x39E2f0E87027093C6Ffe76A4d2f20AEE479E5f64";
      var tx = {
        from: admin,
        to: contract_address,
        gas: 184000,
        data: "",`enter code here`
        chainId: "1337"
      };
      web3.eth.accounts.signTransaction(tx, 'privateKey').then((hash) => {


        web3.eth.sendSignedTransaction(hash.rawTransaction).then((receipt) => {
          resolve();
        }, (error) => {
          console.log(error);
          reject(500);
        });
      }, (error) => {
        reject(500);
      });

    }

    { messageHash: '0x15e3f440015b35151c1343fb9a6be2497c082b47dbce607d32e80c10eff800f1',

Ropsten的链ID为3(参见EIP 155)，但您已经提供了1337。
