nodejs批量ping

       阅读(535)  2017-11-03 09:23:02

在一批大量的ip地址之中查找哪个地址是有效的并且应答的时间最快

nodejs中可以使用net-ping模块

ip地址所在的json文件格式如下,只粘贴部分信息,文件名:gui-config.json

{
	"configs" : [
		{
			"remarks" : "德国",
			"server" : "172.104.155.76",
			"method" : "rc4-md5",
			"obfs" : "plain",
			"obfsparam" : "",
			"remarks_base64" : "5b635Zu9",
			"tcp_over_udp" : false,
			"udp_over_tcp" : false,
			"protocol" : "origin",
			"obfs_udp" : false,
			"enable" : true,
			"id" : "12-AC-19-DF-D8-3D-2F-F3-8C-52-34-C3-8B-12-B6-F5"
		},
		{
			"remarks" : "俄罗斯",
			"server" : "92.38.129.13",
			"method" : "rc4-md5",
			"obfs" : "plain",
			"obfsparam" : "",
			"remarks_base64" : "5L-E572X5pav",
			"tcp_over_udp" : false,
			"udp_over_tcp" : false,
			"protocol" : "origin",
			"obfs_udp" : false,
			"enable" : true,
			"id" : "0F-4B-E0-06-6E-69-75-D1-E4-68-F2-CD-A2-B3-04-06"
		}
	],
}

nodejs代码

const ping = require ("net-ping");
const session = ping.createSession();
const fs = require('fs');

function pingHost(host) {
  session.pingHost(host, (error, target, sent, rcvd) => {
    if (error) {
      console.log(`${target} failed:${error.toString()}`);
    } else {
      const spent = rcvd.getTime() - sent.getTime();
      console.log(`${target} ok, spent: ${spent}ms`);
    }
  })
}

const guiconfig = 'C:/Users/tujiawei/Downloads/pgfastss/gui-config.json';
const content = fs.readFileSync(guiconfig, 'utf8');
const contentObj = JSON.parse(content);
contentObj.configs.forEach((item) => {
  pingHost(item.server);  
})

需要注意的是,我的机器运行这个js文件在windows下需要管理员权限
所以,用管理员权限运行cmd(打开命令行提示工具),cd到指定目录执行

node ping.js

结果如下:

60.248.112.164 ok, spent: 44ms
175.98.163.226 ok, spent: 63ms
175.98.163.216 ok, spent: 67ms
92.38.129.13 ok, spent: 72ms
47.88.224.254 ok, spent: 75ms
103.76.104.227 ok, spent: 165ms
45.58.54.190 ok, spent: 166ms
