Question

我试图缩小此nodejs脚本的实时输出。

var autobahn = require('autobahn');
var wsuri = "wss://api.poloniex.com";
var connection = new autobahn.Connection({
  url: wsuri,
  realm: "realm1"
});

connection.onopen = function (session) {
        function marketEvent (args,kwargs) {
                console.log(args);
        }
        function tickerEvent (args,kwargs) {
                console.log(args);
        }
        function trollboxEvent (args,kwargs) {
                console.log(args);
        }
        session.subscribe('BTC_XMR', marketEvent);
        session.subscribe('ticker', tickerEvent);
        session.subscribe('trollbox', trollboxEvent);
}

connection.onclose = function () {
  console.log("Websocket connection closed");
}

connection.open();

该脚本取自交换的API文档： https://poloniex.com/support/api/

当我在节点中运行它时，我会获得所有货币对的实时更新。如何仅输出所选对？

我在文档中看不到类似内容。

Answer 1

 function tickerEvent (args,kwargs) {
        if(args[0] !== "BTC_SDC"){
            return; // causes anything not "BTC_SDC" related to be filtered out.
        }
        console.log(args); // information you want.
     }

我建议在自动收报机中对该数组的第一项进行套接。
