Use web3js to write scripts to implement automatic transactions of Ether

Note: The script must be run in an environment with web3 installed. If web3 is not installed, please refer to the following blog post.

 CentOS 7 environment web3 installation and object creation_m0_47233175's blog-CSDN blog https://blog.csdn.net/m0_47233175/article/details/121960931 The script code is as follows

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'));

var arguments = process.argv.splice(2);

if(!arguments || arguments.length != 2){
    console.log("Parameter error!");
    return;
}

var _from = arguments[0];
var _to = arguments[1];
var _value = arguments[2];

web3.eth.sendTransaction({from: _from, to: _to, value: _value}, (err, res)=>{
    if(err)
        console.log("Error: ", err);
    else
        console.log("Tx: ", res);
});

  Copy the above script code into a new transfer_script.js file 

 

run script

node transfer_script.js 0x6903269a98f6ef7ea7190fc0122d5e15ddd25526 0x456982ded2a3eb889b3c3774e48de7fd867c0e5a 10000000

Note: The first parameter   after the js file name is the sending address of Ether , the second parameter is the receiving address of Ether , and the third parameter is the number of Ether transactions .
