nodejs批量ping

Posted 2022-08-31 ningto.com

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: $spentms`);
    
  )


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
