Javascript / Blockchain.info Websocket API地址訂閱

Question

我是bitcoin，Blockchain.info API和javascript的新手，但是，我正在嘗試實現一個代碼，該代碼可跟蹤特定比特幣地址上的Live Payments通知。 這里的想法是...在用戶掃描QR圖像<img src="http://chart.googleapis.com/chart?chs=200x200&cht=qr&chl=12fMma2J15qre9bZPsX3AerdgWd9Poe9ee">並付款到BTC地址12fMma2J15qre9bZPsX3AerdgWd9Poe9ee ，編號為#websocket的Div會立即顯示實時（不刷新網頁），已轉移到該地址的比特幣數量，從而將div的初始內容從monitoring...切換為已轉移的數量Recieved: 0.003 BTC 。

我已經寫了一段代碼...但是我不確定我缺少什么。 請幫忙。 謝謝。

編碼：

        <div class="row">
            <div class="col-md-4 "> 
                <img src="http://chart.googleapis.com/chart?chs=200x200&cht=qr&chl=12fMma2J15qre9bZPsX3AerdgWd9Poe9ee"> 
                <div id="websocket">
                    Monitoring Transactions ...
                </div>

                <script>
                var btcs = new WebSocket("12fMma2J15qre9bZPsX3AerdgWd9Poe9ee");
                btcs.onopen = function() {
                    btcs.send(JSON.stringify({"op":"addr_sub", "addr":"12fMma2J15qre9bZPsX3AerdgWd9Poe9ee"}));
                };

                btcs.onmessage = function (onmsg) {
                    var response = JSON.parse(onmsg.data);
                    var getOutputs = response.x.out;
                    var countOuts = getOutputs.length;

                    for (i=0; i < countOuts; i++){
                        var outAdd = response.x.out[i].addr;
                        var address = "12fMma2J15qre9bZPsX3AerdgWd9Poe9ee";
                        if (outAdd == address){
                            var amount =response.x.out[i].value;
                            var calAmount = Amount / 100000000;
                            document.getElementById("websocket").innerHTML = "Recieved" + calAmount + "BTC";
                        }
                    }
                };
                </script>

            <div class="col-md-8">

Answer 1

我在代碼的任何地方都看不到與區塊鏈api的連接，所以我猜這

var btcs = new WebSocket("12fMma2J15qre9bZPsX3AerdgWd9Poe9ee");

應該使用api的地址而不是目標比特幣錢包地址。

Answer 2

可能您需要在地址位置啟動新套接字時放入wss://ws.blockchain.info/inv 。
