NodeJS无法识别ClamAV？nodeClam实例化配置问题求助

问题描述 #

我想用ClamAV实现文件上传流程的病毒扫描，当前用以下代码实例化nodeClam：

const nodeClam = require('clamscan');
...
const clamScan = new nodeClam().init({  
    debug_mode: true,
    preference: 'clamscan',
    clamdscan: {                
        path: '/usr/bin/clamscan',
        local_fallback: true,
        config_file: '/etc/clamav/clamd.conf',
        scan_archives: true,
        active: true,
        port: 3310
    },
});

运行时出现错误：

/app/node_modules/clamscan/index.js:241
                            const err = new NodeClamError(
                                        ^

NodeClamError: No valid & active virus scanning binaries are active and available and no host/socket option provided!
    at /app/node_modules/clamscan/index.js:241:41 {
  data: {},
  date: 2023-04-14T18:35:34.764Z
}

但本地执行clamscan命令完全正常：

$ clamscan /tmp/eicarcom2.zip
/tmp/eicarcom2.zip: Win.Test.EICAR_HDB-1 FOUND

End Date:   2023:04:14 15:08:52

请问我的nodeClam实例化配置是否存在遗漏？

问题根源 #

你把独立扫描工具clamscan的配置错误放到了clamdscan节点下，这是核心问题：

• clamdscan配置项是给ClamAV守护进程（clamd）用的，对应通过网络/套接字调用扫描的场景
• 你实际要用的是本地二进制文件clamscan，需要单独配置clamscan对象

修正后的配置 #

const nodeClam = require('clamscan');
...
const clamScan = new nodeClam().init({  
    debug_mode: true,
    preference: 'clamscan', // 指定优先使用clamscan
    clamdscan: {
        active: false // 不用clamd守护进程就直接禁用
    },
    clamscan: { // 单独配置clamscan参数
        path: '/usr/bin/clamscan',
        config_file: '/etc/clamav/clamd.conf',
        scan_archives: true,
        active: true // 激活clamscan
    }
});

额外检查点 #

• 确认Node.js进程对/usr/bin/clamscan有执行权限，可通过chmod +x /usr/bin/clamscan或调整进程用户组解决
• 开启debug_mode: true后，查看详细日志，确认nodeClam是否能正确找到并调用clamscan二进制文件
• 若仍有问题，可尝试简化配置，只保留path和active两个必要参数，逐步排查其他配置项的影响
