在 NodeJS ClamScan 中产生错误 /usr/bin/clamscan

问题描述

我正在运行一个简单的 clamscan 示例。

const NodeClam = require('clamscan');

let options = {
    debug_mode: true,// clamdscan: {
    //     socket: '/var/run/clamav/clamd.ctl',// This is pretty typical
    //     host: '127.0.0.1',// If you want to connect locally but not through socket
    //     port: 3310,// Because,why not
    //     timeout: 300000,// 5 minutes
    //     local_fallback: true,// Use local preferred binary to scan if socket/tcp fails
    //     path: '/usr/bin/clamdscan',// Special path to the clamdscan binary on your server
    //     config_file: '/etc/clamav/clamd.conf',// A fairly typical config location
    //     multiscan: false,// You hate speed and multi-threaded awesome-sauce
    //     reload_db: true,// You want your scans to run slow like with clamscan
    //     active: false,// you don't want to use this at all because it's evil
    //     bypass_test: true,// Don't check to see if socket is available. You should probably never set this to true.
    // },preference: 'clamscan' 
};


async function some_function() {
    try {
        // Get instance by resolving ClamScan promise object
        console.log("-------------------hello world------------------------------");
        const clamscan = await new NodeClam().init(options);
        //console.log(clamscan);
        console.log("--------------------------------------------------------hello world------------------------------------------------");
        const {good_files,bad_files} = await clamscan.scan_dir('/home/abhishek/Desktop/JSINFO',);
        console.log("----------------------------------------------------------hello world--------------------------------------------------------------------");
        console.log(good_files);
    } catch (err) {
       console.log(err);
    }
};
 
some_function();

但是，我收到了这样的错误：

节点蛤：标准输出： node-clam： 已感染！ (node:109042) UnhandledPromiseRejectionWarning: E​​rror: Error: spawn /usr/bin/clamscan --no-summary --stdout.

位置 /usr/bin/clamscan 中有一个 clamscan 文件。但这还是来了

解决方法

我通过使用 Promise 函数而不是异步函数成功地使 scan_dir 工作......我想这是库中的一个问题，但如果你使用它，它应该可以工作:)

const NodeClam = require('clamscan');
const ClamScan = new NodeClam().init();


function main() {
  // Get instance by resolving ClamScan promise object
  ClamScan.then(async clamscan => {
      try {
          // You can re-use the `clamscan` object as many times as you want
          const path = '/path/to/your/folder';
          const version = await clamscan.get_version();
          console.log(`ClamAV Version: ${version}`);
  
          clamscan.scan_dir(path,(err,good_files,bad_files,viruses) => {
            if (err) return console.error(err);

            console.log(good_files);
        
            if (bad_files.length > 0) {
                console.log(`${path} was infected. The offending files (${bad_files.join (',')}) have been quarantined.`);
                console.log(`Viruses Found: ${viruses.join(',')}`);
            } else {
                console.log("Everything looks good! No problems here!.");
            }
          });
      } catch (err) {
          // Handle any errors raised by the code in the try block
      }
  }).catch(err => {
      // Handle errors that may have occurred during initialization
  });
}

main();
