javascript - http.get() 中的每秒请求数 - Node.js

Question

我正在 node.js 中做一个 super 基本的 http 请求应用程序。

var http = require('http');

var options = {
  host: 'www.domain-here.com',
  port: 80,
  path: '/index.html'
};

for(var i = 0; i < 500; i++) {
    http.get(options, function(res) {
            console.log("[" + this.count + "] Response: " + res.statusCode);
    }.bind({ count: i })).on('error', function(e) {
            console.log("[" + this.count + "] Error: " + e.message);
    }.bind({ count: i }));
}

不过，我需要获取每秒的 http 请求数。知道我如何每秒获取请求吗？

Answer 1

// begin timestamp
var begin = new Date();

for(var i = 0; i < 500; i++) {
    http.get(options, function(res) {
            console.log("[" + this.count + "] Response: " + res.statusCode);
    }.bind({ count: i })).on('error', function(e) {
            console.log("[" + this.count + "] Error: " + e.message);
    }.bind({ count: i }));
}

// end timestamp
var end = new Date();

// Then, you need a simple calculation
var reqPerSec = i / ( end - begin );
