This is a sample code snippet that transfer ERC20 tokens:
import { VdsRPC } from "vdsjs"
const repoData = require("./solar.json")
const vds = new Vds("http://vds:test@localhost:3889", repoData)
const myToken = vds.contract(
"zeppelin-solidity/contracts/token/CappedToken.sol",
)
async function transfer(fromAddr, toAddr, amount) {
const tx = await myToken.send("transfer", [toAddr, amount], {
senderAddress: fromAddr,
})
console.log("transfer tx:", tx.txid)
console.log(tx)
await tx.confirm(3)
console.log("transfer confirmed")
}
This is a sample code snippet that sample contract:
const {Contract, VdsRPC} = require("vdsjs")
const rpc = new VdsRPC("/")
const contractInfo = require("./MilFold.json");
const milFold = new Contract(rpc, contractInfo);
//单参数
function getHistoryRoundInfo(args) {
let callResult = milFold.call("getHistoryRoundInfo", args);//返回16进制数据
callResult.then(data => {
console.log(JSON.stringify(data));
console.log(JSON.stringify(data.outputs));
});
let funcArgs = [];
funcArgs.push(args)
let callParseData = milFold.callFunc("getHistoryRoundInfo", funcArgs);//返回10进制数据
callParseData.then(data => {
console.log(JSON.stringify(data));
});
}
//多参数
function getPlayerRoundNums(...args) {
let callArgs = [];
callArgs.push(args[0][0])
callArgs.push(args[1][0])
let callResult = milFold.call("getPlayerRoundNums", callArgs);
callResult.then(data => {
console.log(JSON.stringify(data));
console.log(JSON.stringify(data.outputs));
});
let funcArgs = [];
funcArgs.push(args[0])
funcArgs.push(args[1])
let callParseData = milFold.callFunc("getPlayerRoundNums", funcArgs);
callParseData.then(data => {
console.log(JSON.stringify(data));
});
}
let chaindemo = {
getHistoryRoundInfo: function (args) {
getHistoryRoundInfo(args);
},
getPlayerRoundNums: function (...args) {
getPlayerRoundNums(...args);
}
};
export default chaindemo;
