基本上我一直试图弄清楚如何使用bitcoinjs-lib来拥有一个快速简便的钱包(在节点js中)。这个程序不是一个完整的钱包,它只需要能够判断比特币地址何时收到付款以及收到多少钱。

您可以使用Blockchain.info的WebSocket服务获取地址更新,然后计算通过输出收到的总金额:
var WebSocket = require('ws');
var btcWS = new WebSocket("wss://ws.blockchain.info/inv");
var BTC_ADDR = "1FoxBitjXcBeZUS4eDzPZ7b124q3N7QJK7";
// NOTIFY ON ADDRESS UPDATE
btcWS.onopen = function(){ btcWS.send(JSON.stringify({ "op": "addr_sub", "addr" : BTC_ADDR })); };
// WE GOT AN UPDATE
btcWS.onmessage = function(msg){
var response = JSON.parse(msg.data);
var getOuts = response.x.out;
// LET'S CHECK THE OUTPUTS
getOuts.map(function(out,i){
if ( BTC_ADDR == out.addr ){
var amount = out.value;
var calAmount = amount / 100000000;
console.log(calAmount + " BTC"); // <-- The total amount just received
}
});
};
btcWS.onerror = function (error){ console.log('connection.onerror', error); };
