Question

我有人声称我的网站使用了相当大量的带宽，他们的互联网提供商正在限制他们或类似的东西。

关于如何获取客户端每秒接收和发送的数据量的任何想法？我想在可以监控的地方（在客户端的屏幕上）显示少量使用情况。

看起来这是可能的，我找到了gist。我测试了它似乎工作！

它不是特定于socket.io，~~我找不到任何东西~~（ooooh我发现this）。但看起来您可以将其实现为服务器上的emit函数来计算发送的字节数。祝你好运。

const net = require("net");

var server = net.createServer(function (c) {
    var oldWrite = c.write;
    c.write = function(d) {
            if (!Buffer.isBuffer(d)) {
                    d = new Buffer(d);
            }
            oldWrite.call(this, d);
            server.bytesSent += d.length;
    };

    c.on('data', function(d){
            server.bytesReceived += d.length;
    });

    c.write('Hello world!\r\n');
    c.pipe(c);
    c.end();
});

server.bytesReceived = 0;
server.bytesSent = 0;

server.listen(3000);

var units = ["B", "kB", "MB", "TB"];
function simplifiedUnits(input) {
    var unit = units[0];
    var i = 0;
    while (input > 1024 && ++i) {
            unit = units[i];
            input /= 1024;
    }
    return Math.round(input) + " " + unit;
}

var time = process.hrtime();
setInterval(function (){
    process.stdout.write('\u001B[2J\u001B[0;0f');
    var diff = process.hrtime(time)[0] + process.hrtime(time)[1]/1000000000;
    var bpsSent = Math.round(server.bytesSent/diff) || 0;
    var bpsReceived = Math.round(server.bytesReceived/diff) || 0;
    console.log("Running node.js %s on %s-%s", process.version, process.platform, process.arch);
    console.log("Memory usage: %s", simplifiedUnits(process.memoryUsage().rss));
    console.log("Uptime: %ds", Math.round(process.uptime()));
    console.log("Open connections: %d", server.connections);
    console.log("In: %s (%s/s)", simplifiedUnits(server.bytesReceived), simplifiedUnits(bpsReceived));
    console.log("Out: %s (%s/s)", simplifiedUnits(server.bytesSent), simplifiedUnits(bpsSent));
}, 100);

我可以检测Socket.IO客户端节点使用的带宽吗？
