nodejs批量ping

来源：互联网发布：詹姆斯数据历史排名编辑：程序博客网时间：2024/04/19 19:31

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：
